I Built prems.ai After Trying replyagent — Honest Comparison (2026)

I'm Amir. I built prems.ai after trying replyagent.ai for two months and concluding it solved the wrong problem for me. That's a biased opening sentence and you should weigh this entire post with that bias in mind. To balance the bias, I'm going to spend more time in this post on what replyagent does better than prems.ai than on what prems.ai does better than replyagent — because if I'm telling you to pick my tool over a competitor's, the burden of honesty is on me.

This is a head-to-head. The short version: replyagent and prems.ai are the two strongest tools in the post-GummySearch Reddit prospecting category. They make opposite tradeoffs on the most important axis — who posts the comments. Pick the wrong one for your stage and you'll either burn money or get an account suspended. There's also a longer ranking of all nine tools in the category if you want broader context.

If you only have ninety seconds: jump to the decision tree. If you want the full analysis with pricing math, account-safety implications, and steel-manned positions on both sides — read on.

What both tools actually do (the part nobody disagrees on)

Both replyagent.ai and prems.ai do the same five things at the surface level:

1. Take a list of keywords and ICP context from you at setup.
2. Watch Reddit (and now LinkedIn, on both products) for new comments and posts matching those keywords.
3. Run each candidate through an LLM-grade relevance scorer to filter out noise.
4. Surface the relevant ones in a dashboard with full thread context.
5. Generate a draft first message tailored to the comment.

If that's all you needed to know about a tool, the two products are interchangeable. They're not interchangeable. The difference is what happens between step 5 and the customer landing in your inbox — specifically, who posts the comment that starts the conversation. That single decision cascades into pricing, account-safety risk, brand voice control, scaling economics, and team workflow. The rest of this post is about that one decision.

The pain that makes this category exist

Reddit is the most under-priced B2B lead source in 2026. The audience tells you exactly what they're frustrated with, the cost-per-warm-lead is in the cents when paid tools are run well, and the conversion-to-paying-customer rate from "I noticed you mentioned X" outreach runs 5–8× cold-email benchmarks because the prospect literally just said they want X.

The bottleneck has never been whether Reddit works. It's that nobody — and I mean nobody, including me before I built prems.ai — wants to spend three hours a day reading r/SaaS, r/Entrepreneur, r/marketing, r/SmallBusiness, and forty other niche subreddits to find the four people that week who said "I wish there was a tool that…"

Both prems.ai and replyagent solve the same surface-level pain: you don't read Reddit, the tool reads Reddit, you act on the four-people-per-week who matter. The disagreement is about act on.

replyagent.ai — the deep dive

What it is. replyagent.ai is a Reddit prospecting platform whose flagship offering is managed posting. You feed them keywords and ICP context. Their human team writes and posts comment replies on your behalf. You pay $3 per comment posted, success-based — they don't get paid for posts you don't approve.

There's also a software-only tier in the $49/mo range last I checked, which is keyword tracking + AI scoring + drafts without the managed posting. That tier exists but it's not what they lead with on the homepage and not what most of their content is about. The managed offer is the company.

Founder. Sheldon Niu, publicly active on the company's content. Ships fast. The product has improved noticeably between when I first tried it in late 2024 and 2026. Worth saying because in this category there are several "tools" that are screenshots and a Stripe button — replyagent is a real product run by a real team.

Pros (genuine, not damning-with-faint-praise).

The success-based pricing is genuinely well-aligned. You don't pay for posts you reject. You don't pay a flat monthly fee that you keep paying after you stop using the product. If you post 12 comments in a month, you spend $36; if you post 80, you spend $240. The cost matches your activity level — that's rare in SaaS.

The managed team writes in a recognizably human voice. I've seen comments their team posted that I would not have flagged as "managed" if I didn't know. That's hard. Most outsourced commenting reads as outsourced commenting.

If you've tried DIY Reddit prospecting once and bounced — sat at a screen for two hours, drafted three comments, posted none of them, decided this isn't for you — replyagent removes the activation energy. The hardest part of Reddit prospecting is not the finding; it's the writing-while-uncertain-about-tone. Outsourcing that step gets actual comments shipped, which gets actual conversations started, which gets actual customers acquired.

The success-based model also works well for agency operators managing multiple client accounts. Resell at $5 or $7 per posted comment, keep the margin, scale the operation without owning the writing capacity yourself.

Cons (genuine, not the polite version).

Account safety is the central tradeoff. Reddit's terms of service prohibit automated posting and treat commercial activity from low-karma accounts as spam. replyagent's managed team mitigates this carefully — they age accounts, they participate in non-promo conversations to build karma, they post selectively rather than at volume — but the residual risk lives on your account. If Reddit's anti-spam systems flag your account for commercial activity that violates a subreddit's promo rules, you don't get compensated. The downside is asymmetric: managed posting is convenient until the day your account is suspended and the conversations you'd built up disappear with it.

Unit economics get rough at scale. At $3/comment, posting 100 comments/month is $300; 200 comments/month is $600. The economics are competitive with prems.ai's $79/200-leads pack only if your conversion-per-comment rate is materially higher, which is empirically a coin flip. Past about 500 comments/month the math starts to favor switching to a manual-send workflow regardless of which tool you're using, because hiring half an SDR at $30K/yr can outpace per-comment fees at that volume.

The third con is brand-voice control. The managed team is good but it's not you. If your brand voice has unusual rhythm, niche references, or specific vocabulary, you'll either spend time training the team (which costs you the time savings you bought) or accept comments that sound 85% like you instead of 100%.

Real use case where replyagent wins. A Series-A B2B SaaS that's already paying an SDR $80K/yr to do this manually. The math: replyagent at ~$1,500/mo posting cost replaces the Reddit-prospecting hours of an SDR who's also doing other work, freeing those hours for higher-leverage activity. Obvious win. If the SDR was only doing Reddit, the calculation is closer.

Where replyagent loses. Pre-revenue or low-revenue founders whose hourly rate is effectively zero, who can write the comments themselves at no marginal cost. Brand-voice-sensitive founders whose readers will instantly clock anything that doesn't sound like them. Founders who have intuition about "this comment is worth posting and this one isn't" that they can't articulate to a managed team in a brief.

prems.ai — the deep dive

What it is. prems.ai is a Reddit + LinkedIn prospecting platform that finds keyword mentions, scores them with an AI relevance model, and drafts a personalized first message. You post the message. The product deliberately does not include a managed-posting tier.

Founder. Me. I started building it after trying replyagent and concluding the managed-posting model was the wrong tradeoff for the kind of user I wanted to serve. That's the entire founder narrative — there's no marketing copy hiding a different origin story.

Pricing. Pay-per-lead credit packs. Entry pack $20 for 25 leads (~$0.80/lead). Volume pricing scales toward $0.33–$0.50/lead at higher tiers. There's a $29/mo base plan that includes 25 free leads, dashboard access, two keyword slots, and unlimited AI-pitcher drafts. The pricing page has the current tiers — credit packs evolve quarterly as we tune the unit economics.

Pros (genuine, written by the founder so weight accordingly).

Cost-per-lead is the lowest I'm aware of in the category once you actually convert customers. At a 5% conversion rate from "warm lead I messaged" to "paying customer," the CAC math at $0.40/lead works out to roughly $8 per customer acquired. That's not a typo. The math holds across a wide range of pessimistic conversion assumptions — at 1% conversion, CAC is still only $40.

LinkedIn coverage matters more than the category gives it credit for. B2B intent often shows up in LinkedIn comments before Reddit threads — a frustrated founder posts on LinkedIn first, then writes the longer-form Reddit thread a week later. Catching the LinkedIn signal early lets you reach out before the Reddit thread even exists.

The AI relevance scoring noticeably outperforms keyword-only or lighter-AI tools. False-positive rate landed around 15% in my own fourteen-day test versus 40–60% for tools with weaker scoring. The AI Pitcher drafts a first message that's roughly 70% usable; you tighten the last 30% and send. The 30% tightening is also the reason you don't sound like a managed team.

The credit-pack model rewards seasonal usage. If you do prospecting bursts (launch month, big release) and quiet months in between, you don't pay flat fees for unused capacity. Credits don't expire on the timescales most founders care about.

Cons (genuine, even though I built it).

You still send the messages yourself. If the activation energy of writing-while-uncertain-about-tone is your bottleneck, prems.ai doesn't fix it. Some users explicitly want a managed offer and we deliberately don't have one. We refer those users to replyagent or to a freelance Reddit-comment service. That's not lip service; we lose deals to replyagent regularly because of this.

Onboarding takes 15 minutes. You set keywords, pick subreddits, configure scoring sensitivity, calibrate the AI Pitcher to your voice. It's not a five-minute tool. The friction is intentional — calibrated keywords convert 3–4× better than uncalibrated ones — but it's still friction.

The credit-pack model is unfamiliar to anyone used to flat subscriptions. Some users find that friction at signup; we lose a percentage of "could you just charge me $99/mo" buyers. We've kept the model anyway because the unit economics for the customer are better — but it costs us conversion at the top of funnel.

The third con is brand exposure. Because you post, your account is the surface. We give you guidance on account aging, karma building, and subreddit-specific promo rules in the docs, but you're the one walking in. If you'd rather not have your account anywhere near commercial activity, replyagent's managed model removes that exposure.

Real use case where prems.ai wins. Solo founders, indie hackers, two-to-five-person SaaS teams. People whose hourly rate isn't high enough to make $3/comment economical but who can spend 20 minutes a day reviewing a curated dashboard of warm leads. People who care about brand voice. People with seasonal usage patterns. Agency operators serving small clients where flat subscriptions are easier to bill than per-comment.

Where prems.ai loses. Founders who want managed posting and won't change their mind. Brand-monitoring use cases where Reddit is one of thirty signals (Brandwatch wins those). Pre-revenue side projects where $20 is too much (F5Bot is the answer there).

GummySearch — context only

GummySearch was the dominant Reddit-research tool from 2022 to mid-2025. It sunset in late 2025. If you find old reviews recommending GummySearch, treat them as historical — the URLs resolve to a sunset notice. Its dispersed user base is most of the demand that replyagent and prems.ai are competing for in 2026. Worth knowing because it explains why the category feels crowded right now: ~15,000 users got displaced in a six-month window and several tools are racing to capture them.

Subreddit Signals — adjacent but different job

What it is. subredditsignals.com indexes Reddit conversations and surfaces trends — what's heating up, which threads are gaining traction, what language people are using. It's category-research, not direct prospecting. Lead surfaces fall out as a side effect of trend tracking.

Pricing. Tiered subscription, last I checked starting around $39/mo for solo and climbing into the $200s for team plans.

Pros. Trend visualization is genuinely strong — answers questions like "is interest in Reddit prospecting itself growing or shrinking?" Subreddit-level analytics help you decide where to invest in community participation. Useful for brand strategy work that informs ICP definition.

Cons. Not optimized for "I have a product, find me people asking for it." You can hack it into that role but you'll wish you'd used a purpose-built tool. Alert latency for individual mentions trails the leaders. AI relevance scoring is lighter than what prems.ai or replyagent run.

Why it's in this comparison. Some readers reach this post thinking they need a prospecting tool when they actually need category research. Subreddit Signals is the right answer for the latter. Don't pay prems.ai or replyagent prices for a research-shaped job.

Linkeddit — the cross-platform mid-pack option

What it is. linkeddit.com indexes both Reddit and LinkedIn for mentions and exposes them through a unified dashboard. Pitch is cross-platform coverage for buyers who don't want to run two tools.

Pricing. Tiered subscription — verify on the live page.

Pros. Cross-platform unification is real and competitive at the dashboard level. Affordable entry tier. Solid for marketers who already track LinkedIn for brand mentions and want Reddit added without buying a second product.

Cons. AI relevance scoring is lighter than the top three. UX feels less polished. Smaller community, fewer integrations, and slower response time on edge cases.

Why it's in this comparison. Honest mid-pack. Doesn't lead on any single axis but doesn't actively fail anywhere. Worth knowing about if budget is tight and you want both platforms covered.

RedReach — the earlier-stage challenger

What it is. redreach.ai is a Reddit-only mention-tracker with AI scoring and draft suggestions. Newer entrant, smaller team.

Pricing. Tiered subscription, roughly $29–$99/mo range.

Pros. UX is clean. Pricing is competitive at entry. Ships steadily. AI relevance scoring is functional and improving.

Cons. No LinkedIn coverage at the time of writing. Smaller team. Analytics depth trails the more established tools.

Why it's in this comparison. If you don't need LinkedIn and you want a competitively priced Reddit-only tool, RedReach deserves a look. Not yet at the level of prems.ai or replyagent for full B2B prospecting workflows, but improving.

Head-to-head comparison matrix

The "who posts" row is the central decision in this category. Every other row falls out of it.

Decision tree — which one fits you

Pick replyagent if all three are true.

• Your hourly rate is genuinely above $200 (founder of a Series-A or later, agency owner, consultant, late-stage operator).
• You've tried DIY Reddit prospecting once and bounced because the writing-while-uncertain part is your bottleneck.
• You're willing to accept residual account-safety risk on your Reddit handle in exchange for the convenience of someone else writing the comments.

If those are all true, replyagent is the right tool and prems.ai is the wrong tool. Pay them.

Pick prems.ai if any of these are true.

• You're a solo founder, indie hacker, or two-to-five-person team with hourly opportunity cost below $200.
• Brand voice control matters to you specifically — your readers can clock anything that isn't you.
• Your usage is seasonal (launch months, release pushes, quiet stretches).
• You want to keep account-safety risk under your direct control rather than delegated to a third party.
• Unit economics matter to you and you're willing to spend 15 minutes a day reviewing a curated dashboard.

If any of those resonate, prems.ai is the right tool. The entry pack is $20 — if it doesn't work for your ICP, you've spent $20 to find that out.

Pick neither if.

• You're pre-revenue and $20/mo is too much. Use F5Bot (free) plus DIY review until you have revenue.
• Your job is brand monitoring across thirty sources, not lead-gen specifically. Use Brandwatch or Mention.
• You need only category research, not lead surfacing. Use Subreddit Signals.
• Your ICP is pure consumer (fashion, lifestyle, beauty). Reddit is not your channel; Instagram or TikTok is.

Counter-position — why the "who posts" decision is the whole game

This is the section where I'm most biased and you should weight it accordingly. I'm going to make the case for the position prems.ai takes and try to steel-man replyagent's position fairly.

The prems.ai position. Account safety should be under the founder's direct control, not delegated. Reddit's anti-spam systems are improving and the line between "managed promotional commenting" and "automated promotional spam" is blurring. When that line moves — and it has moved several times — accounts on the wrong side of it get suspended. If your account is suspended, the relationships you've built on Reddit are gone. The cost of building those relationships is sunk. Therefore, the founder who controls the activity also controls the risk, and that's where the risk should live.

The corollary: doing prospecting yourself forces you to participate in the communities, learn the norms, build genuine karma, and integrate. The founders who do this for six months become better at sales and marketing. The ones who outsource it stay where they were. Skill compounding lives on the side that does the work.

The replyagent steel-man. Founder time is the scarcest resource in a startup. Outsourcing comment-writing to a trained team is exactly the kind of leverage that separates founders who scale from founders who don't. The risk argument is overstated — replyagent's managed team operates carefully, in the same way that a virtual assistant managing your calendar carries some residual risk that they'll send the wrong meeting to the wrong person, but you delegate anyway because the time arbitrage is real. The "skill compounding" argument is romantic but doesn't hold for someone whose comparative advantage is product, not Reddit-comment writing.

Where I land. Both positions are defensible. The right answer depends on which scarcity binds harder for you — time (replyagent) or account-safety risk (prems.ai). For most readers of this post — solo founders, indie hackers, small teams — I think the account-safety bind is harder. For Series-A founders with SDR budgets, the time bind is harder. That's why both companies exist, that's why both are in business, and that's why this post ranks them as the two leaders rather than picking one and trashing the other.

The pricing math both companies want you to do

Let me show the math the way I run it for prems.ai so you can run it your own way for either tool.

Inputs you supply.

• Your average customer LTV: LTV
• Your conversion rate from "warm lead I messaged" to paying customer: C
• Your cost per outreach attempt (lead OR comment): K

Math.

• Cost per converted customer: K / C
• Net contribution per customer: LTV − (K / C)
• ROI multiple: LTV / (K / C)

A worked example for prems.ai at $0.40/lead, 5% conversion, $480 LTV.

• Cost per converted customer: $0.40 / 0.05 = $8 per customer
• Net contribution: $480 − $8 = $472 per customer
• ROI multiple: $480 / $8 = 59×

The same math for replyagent at $3/comment, 8% conversion (managed posts convert higher in good operators' hands), $480 LTV.

• Cost per converted customer: $3 / 0.08 = $37.50 per customer
• Net contribution: $480 − $37.50 = $442.50 per customer
• ROI multiple: $480 / $37.50 = 12.8×

Both ROI multiples are excellent. Both clearly beat LinkedIn ads at 1–3× and cold email at 2–5×. The replyagent multiple is lower mostly because the per-attempt cost is higher; if you can sustain meaningfully higher conversion than 8% with managed posts (some operators report 12–15%), the gap closes considerably.

Run this math on your LTV, conversion, and cost. Whichever tool produces the higher net contribution per customer for your inputs is the right tool. If the multiple is below 5× for either tool, your problem isn't the tool — it's ICP fit or message fit, neither of which switching tools will fix.

CTA

If this honest comparison convinced you that replyagent is the right tool for your stage, their site is here — they're a serious team running a real product, and I'd rather you pick the right tool than pick mine.

If this convinced you that prems.ai is the right tool for your stage, start with the $20 entry pack. Two weeks of AI-scored leads with drafts. If the math doesn't work for your ICP, you've spent $20 to find that out. If it does work, the volume packs are where the unit economics get really compelling.

Either way: don't keep reading Reddit for three hours a day. The math doesn't work.

FAQ

What's the single biggest difference between prems.ai and replyagent.ai? prems.ai finds the leads and drafts the message; you post. replyagent.ai finds the leads, drafts the message, and posts on your behalf for $3 per comment. Every other difference cascades from that single decision.

Is replyagent's managed posting against Reddit's terms of service? Not strictly — they post manually through their team, not via automation. But Reddit's anti-spam policies treat commercial activity at scale as suspect regardless of who clicks "post." replyagent mitigates this carefully but the residual risk lives on your account. They're transparent about this in their docs.

Is prems.ai cheaper than replyagent? Per attempt, yes — $0.40/lead vs $3/comment. Per converted customer, depends on your conversion rate. Run the math on your own LTV and conversion to see which produces higher net contribution.

Does account safety actually matter? Reddit doesn't ban accounts that often. It matters more in some subreddits than others. r/Entrepreneur and r/SaaS have strict promo rules; many niche subreddits have no patience for commercial activity. The risk concentrates in the subreddits most worth prospecting in, which is the unfortunate part.

Can I use both tools? Yes, plenty of users do — replyagent for high-volume keywords where managed posting beats their hourly rate, prems.ai for niche keywords where they want to write the comment themselves. The tools don't conflict.

Which tool has better AI relevance scoring? Both run frontier-quality LLMs for relevance scoring. In my fourteen-day test, false-positive rates were within a few percentage points of each other and well below tools with weaker AI layers. The differentiator isn't scoring quality; it's the posting decision.

Which tool has better LinkedIn coverage? Both cover LinkedIn now. prems.ai has had it for longer and has deeper analytics on LinkedIn-specific signals. replyagent added it more recently and is catching up.

How long until I see the first lead? For both tools, the first relevant mention typically lands within 24–72 hours of setup, depending on keyword volume. The right keyword can land within an hour. The wrong keyword (too broad, too many false positives) can produce nothing useful for a week.

Can I export leads to my CRM? Both tools support CSV export and Zapier/webhook integrations. Native CRM connectors (HubSpot, Salesforce) are typically a paid-tier feature on both.

What happens if I scale beyond 600 leads/month? For prems.ai, contact sales for custom-volume tiers above the published packs. For replyagent at $3/comment, scaling means linearly higher cost — past about 500 comments/month the math starts to favor a manual-send workflow regardless of which tool.

Why would I pick replyagent over prems.ai? Three reasons: (1) your hourly rate is genuinely above $200 and writing comments yourself is uneconomical, (2) you've tried DIY Reddit prospecting and the writing-while-uncertain part is your bottleneck, (3) you accept the account-safety tradeoff in exchange for the time savings.

Why would I pick prems.ai over replyagent? Several: lower cost-per-lead at volume, brand voice control, account safety under your direct control, seasonal credit usage that doesn't waste capacity, and the skill-compounding effect of doing the work yourself.

Is there a tool that does both managed and DIY posting? Not at meaningful quality. You can buy two tools, but the dashboards don't unify and the workflow gets messy fast. Pick one for your primary use, add the other only if you have a clearly differentiated secondary use case.

How does this compare to cold email? Both Reddit prospecting tools dramatically outperform cold email on reply rate (25–40% vs 1–3%) and customer NPS (warm leads who self-identified the problem churn less). Cold email scales further at lower per-attempt cost; Reddit prospecting wins on conversion quality. Not mutually exclusive — most teams run both.

Should I just hire an SDR instead? SDR salary at $80K/yr fully loaded ≈ $6,700/mo. Replacing that with replyagent at $3/comment posts ~2,200 comments/mo before matching cost. Replacing with prems.ai at $0.40/lead handles ~16,000 leads/mo. For most teams the tools win on raw economics until you need an SDR's other skills (qualification calls, demos, contract negotiation) — at which point you hire the SDR for those skills and use the tools to feed the top of their funnel.

What if I want to test both? Run them in parallel for 30 days with the same keyword set on different (aged, healthy) accounts. Track close rate by source. Pick whichever wins. Total cost of the experiment: ~$100 in tool fees, plus your time. Cheaper than a wrong six-month commitment to either.

Je m'appelle Amir. J'ai construit prems.ai après avoir essayé replyagent.ai pendant deux mois et conclu qu'il résolvait le mauvais problème pour moi. C'est une phrase d'introduction biaisée et vous devriez peser tout cet article avec ce biais à l'esprit. Pour équilibrer le biais, je vais passer plus de temps sur ce que replyagent fait mieux que prems.ai que sur ce que prems.ai fait mieux.

Ce que les deux outils font (la partie sans désaccord)

Les deux outils font cinq choses identiques en surface :

1. Prennent une liste de mots-clés et de contexte ICP au démarrage.
2. Surveillent Reddit (et maintenant LinkedIn, sur les deux produits) pour les nouveaux commentaires correspondants.
3. Passent chaque candidat à travers un scoreur de pertinence LLM pour filtrer le bruit.
4. Affichent les pertinents dans un tableau de bord avec contexte complet.
5. Génèrent un message d'accroche personnalisé.

La différence est entre l'étape 5 et le client qui arrive dans votre boîte mail — qui poste le commentaire qui démarre la conversation. Cette unique décision se répercute sur les prix, le risque de sécurité du compte, le contrôle de la voix de marque, l'économie d'échelle, et le workflow d'équipe.

replyagent.ai en bref

Ce que c'est. Plateforme de prospection Reddit dont l'offre phare est la publication gérée. Vous fournissez les mots-clés et le contexte ICP. Leur équipe humaine écrit et poste les réponses pour vous. 3$ par commentaire posté, succès-basé.

Avantages. Prix aligné sur les résultats. L'équipe gérée écrit avec une voix humaine reconnaissable. Élimine l'énergie d'activation pour les fondateurs qui ont essayé le DIY et abandonné. Bon pour les agences gérant plusieurs comptes clients.

Inconvénients. Sécurité du compte est le compromis central — Reddit interdit la publication automatisée et traite l'activité commerciale à l'échelle comme du spam. Le risque résiduel vit sur votre compte. Économie unitaire dégrade à l'échelle (300$/mois pour 100 commentaires). Contrôle de la voix de marque limité.

Pour qui. Startups Series-A avec budget SDR. Agences. Fondateurs dont le taux horaire dépasse 200$ et qui n'ont pas la patience d'écrire des commentaires Reddit.

prems.ai en bref

Ce que c'est. Plateforme de prospection Reddit + LinkedIn qui trouve les mentions, les score avec un modèle IA, et rédige un message personnalisé. Vous postez le message. Pas de publication gérée — délibérément.

Prix. Packs de crédits pay-per-lead. Pack d'entrée 20$ pour 25 leads (~0,80$/lead). Volume jusqu'à 0,33-0,50$/lead. Plan de base 29$/mois inclut 25 leads gratuits.

Avantages. Coût par lead le plus bas de la catégorie quand vous convertissez réellement. Couverture LinkedIn (l'intention B2B se manifeste souvent sur LinkedIn avant Reddit). Scoring IA précis (taux de faux positifs ~15% vs 40-60% pour les outils plus faibles). Modèle de crédits récompense l'usage saisonnier.

Inconvénients. Vous postez vous-même les messages. Onboarding prend 15 minutes. Modèle de crédits non familier pour les habitués des abonnements forfaitaires. Votre compte est la surface exposée.

Pour qui. Fondateurs solo, indie hackers, équipes de 2 à 5 personnes. Personnes dont le contrôle de la voix de marque compte. Usage saisonnier. Économie unitaire qui compte.

Matrice de comparaison

La ligne "qui poste" est la décision centrale. Tout le reste en découle.

Arbre de décision

Choisissez replyagent si les trois sont vrais :

• Votre taux horaire dépasse réellement 200$.
• Vous avez essayé la prospection Reddit DIY et abandonné parce que la rédaction est votre goulot d'étranglement.
• Vous acceptez le risque résiduel de sécurité du compte en échange de la commodité.

Choisissez prems.ai si l'un de ces points résonne :

• Fondateur solo, indie hacker, ou équipe de 2-5 avec coût d'opportunité horaire inférieur à 200$.
• Le contrôle de la voix de marque compte spécifiquement pour vous.
• Usage saisonnier (mois de lancement, releases).
• Vous voulez garder le risque de sécurité du compte sous contrôle direct.
• L'économie unitaire compte et vous pouvez consacrer 15 min/jour à un tableau de bord curé.

Calcul du ROI

prems.ai à 0,40$/lead, conversion 5%, LTV 480$ :

• Coût par client acquis : 0,40$ / 0,05 = 8$
• Marge nette : 480$ − 8$ = 472$
• ROI : 59×

replyagent à 3$/commentaire, conversion 8%, LTV 480$ :

• Coût par client acquis : 3$ / 0,08 = 37,50$
• Marge nette : 480$ − 37,50$ = 442,50$
• ROI : 12,8×

Les deux multiples ROI sont excellents. Les deux battent les pubs LinkedIn (1-3×) et l'email à froid (2-5×). Faites le calcul sur vos chiffres ; le bon outil est celui qui produit la plus haute contribution nette par client.

Conclusion

Si cette comparaison honnête vous a convaincu que replyagent est le bon outil pour votre étape, leur site est ici — c'est une équipe sérieuse avec un vrai produit.

Si elle vous a convaincu que prems.ai est le bon, commencez avec le pack d'entrée à 20$. Deux semaines de leads scorés par IA avec brouillons. Si le calcul ne fonctionne pas pour votre ICP, vous l'avez découvert pour 20$.
