What is Customer Finder?

Customer Finder is a free tool that turns your website or product description into a targeted Google search across Reddit, LinkedIn, X, Hacker News, Quora, and 25+ other communities. It surfaces threads where people are already asking for what you sell, so you can join an existing conversation instead of starting one cold.

How does Customer Finder find customers?

Paste your URL or describe your product. An LLM picks the most relevant communities and keywords for your product, then builds a Google search using site: operators. You land on a normal Google results page filtered to threads matching your ideal customer profile — typically complaints, recommendations, and product comparisons.

Is Customer Finder really free?

Yes. No signup, no credit card to try it. The paid plan (USD 19 per month) adds unlimited searches plus a daily digest of new conversations matching your product, delivered to your inbox.

What communities does Customer Finder search?

Reddit, LinkedIn, X (Twitter), Hacker News, Quora, Indie Hackers, Product Hunt, GitHub, Stack Overflow, and 20 more — 30+ communities covering B2B, B2C, indie founder, and developer audiences. The picker auto-selects the best 5-9 communities for your product so you do not drown in irrelevant results.

How is Customer Finder different from Sales Navigator or cold outreach?

Sales Navigator and cold-email tools find people who might want what you sell. Customer Finder finds people who have already said they want it — warm intent expressed publicly. You enter an existing conversation about a need, instead of interrupting someone's day with an unsolicited pitch.

Will I get banned posting on Reddit?

Only if you spam. The communities Customer Finder surfaces are public, but each one has rules — most prohibit overt selling. The right approach: comment helpfully, answer the original question, and mention your product only if it is directly relevant and the rules allow it. Learn each community's norms before going wider.

Reddit, X, LinkedIn or Hacker News — Where Are Your Customers Actually Talking?

Published 21 May 2026~8 min read

Pick by who your customer is, not by what's trendy. Reddit fits B2C consumers, indie founders, and developers — high intent, anonymous, long-form. LinkedIn fits B2B SaaS buyers and senior ICs — public identities, professional context. X fits developer tools, design tools, and consumer-creative — short-form, fast feedback. Hacker News fits technical and B2D products — high-credibility, single-shot launches. Most founders should commit to one for 30 days before adding a second.

The mapping that matters

Founders waste months picking the wrong channel because they chose by personal preference instead of customer reality. Here's the rough mapping that holds up in 2026:

Reddit — for B2C, indie founders, and developers

Reddit's anonymous, long-form structure attracts honest opinions and detailed problem statements. It's the strongest channel for:

B2C products — consumers research openly on Reddit before buying; niche subreddits like r/BuyItForLife or r/skincareaddiction drive real purchase decisions.
Indie founder tools — r/SaaS, r/indiehackers, r/Entrepreneur (used carefully; very vendor-saturated).
Developer tools — r/programming, r/webdev, r/devops, and language-specific subs like r/Python, r/rust.

Weak fit: anything where your buyer is a CFO, CMO, or senior executive. They're not on Reddit talking about work. See our deeper Reddit guide.

LinkedIn — for B2B SaaS and senior ICs

LinkedIn is the only social platform where your audience's professional identity is the default. That makes it the right channel for:

B2B SaaS with buyers in marketing, sales, ops, or HR.
Tools sold to mid-market or enterprise where buyer titles matter and procurement processes exist.
Recruiting, professional services, and career-adjacent products.

Weak fit: B2C, anything teenagers buy, gaming, niche hobbies. See our LinkedIn guide.

X — for developer tools and creative products

X is fast, short-form, and rewards novelty. It works best for:

Developer tools and APIs — devs hang out on X; many high-traffic developer launches start there.
Design tools, AI tools, creative products — visual demos travel.
Consumer products with shareable output (productivity, fitness, etc.) — virality is occasional but when it hits, it scales.

Weak fit: long sales cycles, regulated industries, or any product that needs explaining. X's 280-character culture rewards punchlines, not value props.

Hacker News — for high-credibility one-shot launches

HN isn't a community you "engage" with daily — it's a launch venue. A successful Show HN can deliver 50-500 signups in 24 hours from a high-credibility audience (founders, engineers, investors). After the launch, traffic decays fast.

Best for: technical products, developer tools, anything with an "interesting" angle (novel tech, contrarian take, founder story). Worst for: B2C consumer apps with no story beyond "it looks pretty".

Niche forums — the underused channel

Beyond the big four, almost every category has a smaller, more concentrated forum:

r/legaladvice, AvvoStories — legal-tech.
r/medicine, MDLinx — healthcare.
r/sysadmin, ServerFault — IT.
BookwriterDB, Substack notes — writing tools.
Indie Hackers, MicroConf — bootstrapped SaaS.

These forums have 10-100× lower volume than the big four but 10-100× higher signal — the people there are deeply identified with the category. For a sub-$10k-MRR founder, a niche forum with 5000 active members often beats a big platform with 5 million.

The decision framework

Use this checklist to pick your first channel:

Who is your buyer? If their job title matters → LinkedIn. If they're a consumer → Reddit. If they're a developer → all four, with X and HN best for awareness, Reddit for evaluation.
Where do they post questions today? If you don't know, ask three existing or prospective customers. The answer is usually a forum you'd never have thought of.
Where is your competitor active? If they're posting on a channel consistently, it's working for them there.

Pick one, exhaust it for 30 days, then add a second. If you'd rather automate the "who's talking about my category" question across all four platforms, paste your URL on the homepage — Customer Finder runs the searches across 30+ communities in one go.

Frequently asked questions

Which platform is best for B2B SaaS lead generation?

LinkedIn, by a wide margin. The professional context, the buyer titles, and the public engagement norms all align with how B2B SaaS gets evaluated. Reddit can be a useful secondary channel if your product is developer-adjacent or sold to indie founders, but LinkedIn is the primary B2B channel.

Is X (Twitter) still worth it for founders?

Yes, for specific products: developer tools, design tools, AI tools, and creative products with visual demos. X's strength is fast feedback and occasional virality. It's a poor fit for products with long sales cycles, regulated industries, or anything that needs more than a punchline to explain.

Should I be on all the platforms at once?

No. Pick one for 30 days, prove it produces leads, then add a second. Founders who spread across four platforms from day one never compound on any of them. Each channel rewards consistency and contribution before promotion — splitting time across all of them means none gets to the point where it pays off.

What about niche forums versus the big four?

Niche forums (Indie Hackers, MicroConf, industry-specific Discords, legacy phpBB forums) have 10-100× lower volume but 10-100× higher signal. For a sub-$10k-MRR founder, a niche forum with 5000 active members often beats a big platform with 5 million. Ask three customers where they spend time learning — that's your forum.
