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.

Where to Find Your First 10 Customers (When You Have $0 to Spend)

Published 21 May 2026~8 min read

Your first 10 customers won't come from ads, SEO, or product-led growth. They'll come from direct human contact with people who already have the problem your product solves. The five channels that work for $0-budget founders: Reddit niche subreddits, Hacker News Show HN, your existing LinkedIn network, X (Twitter) replies, and niche industry forums. Pick one and exhaust it before adding a second.

Why the "first 10" is different from everything after

The marketing tactics that take you from 10 customers to 100 (SEO, ads, content, partnerships) require things you don't have yet — a track record, testimonials, traffic, or a story. The first 10 is a manual, conversational, slow game where you talk to actual humans and ask them to try your thing. Founders who try to use 100→1000 tactics at this stage spin their wheels for months and conclude their product is broken when really the channel was wrong.

Acquisition cost for your first 10 customers should be measured in hours of your time, not dollars. If you're spending money to find people who'll pay you $19/month, you're solving the wrong problem.

Channel 1 — Reddit niche subreddits

Reddit is the highest-intent free channel because people post problems they want solved, in plain language. Find 3-5 subreddits where your customer hangs out (often a profession or hobby subreddit, not a software-category one), and use Google's site:reddit.com operator to find threads where someone explicitly asks for what you sell.

Don't just post your product — comment on existing threads with substantive help, mentioning your product only when relevant and permitted. See our deeper guide on how to find customers on Reddit.

Channel 2 — Hacker News (Show HN)

If your product is technical, developer-facing, or "interesting" to a startup audience, a single well-timed Show HN can produce more signups in 24 hours than a month of cold outreach. The rules:

Submit Tuesday-Thursday, 7-10am Pacific Time (peaks of US + European traffic).
Title format: Show HN: [Product] – [What it does in <10 words]
First comment, from you, explains the why, the tech, and the ask. Be honest about what's broken — HN respects builders, not marketers.
Respond to every comment in the first 6 hours. The thread dies if you go silent.

Expected outcome: 50-200 signups in 24 hours, mostly developers, mostly not your ICP — but the 5-20 who are your ICP are worth weeks of cold outreach.

Channel 3 — Your existing LinkedIn network

Look through your LinkedIn connections. There are probably 20-30 people who could either be a customer or know one. Send each a personal, non-salesy message: "Hey [name], I'm working on [Product] which does [thing]. You popped to mind because [specific reason about them]. No agenda — would love your read on whether this is dumb."

This converts because it's specific (not a blast), it's humble (not a pitch), and it primes them to either reply with thoughts (free customer interview) or refer you to someone else ("oh you should talk to X").

Channel 4 — X (Twitter) replies

Find 10 accounts your customer reads. These are usually people who post about the problem your product solves (not necessarily about your industry). Reply to their posts with substance for two weeks. The host doesn't see most replies; the audience does. Followers of the host who recognise themselves in your replies will click your profile. If your bio is clear about what you do, conversions follow.

X works better for B2C and developer products than for traditional B2B. For B2B SaaS, LinkedIn and Reddit are stronger first channels.

Channel 5 — Niche industry forums

Beyond Reddit, almost every industry has a smaller, more concentrated forum: WebmasterWorld for SEO, KissAnime-style for media, ResearchGate for academia, Indie Hackers for founders, Hacker News for tech, niche Discords for gaming and creative tools. These have 10-100× lower volume than Reddit but 10-100× higher signal — the people there are deeply identified with the topic.

For your category, ask three customers (or yourself) where they spend time learning. That's your forum.

The "exhaust one channel first" rule

Founders pre-PMF will try Reddit for two days, post once on LinkedIn, send three cold emails, and conclude "nothing works". Pick one channel, commit to it for 30 days minimum, and only add a second once you have data. Channels compound — your second Reddit week is 7× more productive than your first because you've learned the norms.

How to count your first 10 properly

Not signups. Not free trials. Paying customers — or, for a freemium product, users who have come back twice unprompted. The first 10 has to be a real signal that the product is wanted, not a vanity metric of people who clicked a link once. If you can't get 10 paying customers from manual channels, the product (or the positioning) is wrong — and no amount of paid acquisition fixes that.

Frequently asked questions

Should I run ads to get my first 10 customers?

No. Ads are for scaling a proven message; they're terrible for figuring out what the message is. Your first 10 customers should come from manual conversations on free channels (Reddit, HN, LinkedIn, X, niche forums). If you need to pay to acquire people who'd pay $19/month, the product or positioning isn't right yet.

Which channel should I start with?

Pick the one where your customer is most concentrated. For B2B SaaS: LinkedIn and Reddit. For developer tools: Hacker News and Reddit. For B2C with a passionate niche: niche forums and Reddit. For mass-market consumer: skip free channels — you'll need paid acquisition or product-led growth, neither of which is in scope for the first 10.

How long until I get my first customer?

If you commit to one channel for 30 days minimum: 2-4 weeks. The compounding effect of contribution before promotion means week 4 is much more productive than week 1. Founders who hop between channels every few days reset the compounding and rarely get to 10.

What counts as a 'real' first customer?

A paying customer for paid products, or a user who returns twice unprompted for freemium products. Signups, trials, and one-time visitors don't count — those measure curiosity, not desire. The first 10 has to demonstrate that someone wants the product enough to either pay or come back without being chased.
