About this app

Before you spend weeks building, find out if anyone actually wants it.

FirstCustomer helps solo founders and indie builders answer one question:
who will be my first customer?

Describe your idea in a short chat. FirstCustomer turns that into a
hypothesis — your target customer, the problem you're solving, and who
you're NOT building for — then scans public discussions (forums like
Reddit) for people already describing that exact problem in their own
words.

WHAT YOU GET

- A hypothesis canvas built from your idea, in one conversation
- Real pain signals — actual posts from people describing the problem,
ranked by how closely they match
- A running list of potential customers pulled from those signals, so you
know who to reach out to first
- Follow-up tasks queued automatically as new signals come in, so
research doesn't stall after the first session
- One dashboard that tracks signals found, customers identified, and
what's outstanding, across every idea you're testing

WHO IT'S FOR

Solo founders, indie hackers, and early-stage builders who want evidence
before code — not another idea-validation worksheet, but real people
saying real things about the problem you're trying to solve.

HOW IT WORKS

1. Open the app and describe your idea in chat.
2. FirstCustomer asks a few clarifying questions and builds a hypothesis
canvas.
3. It scans public discussions for posts that match your target
customer's problem and ranks them as signals.
4. Signals become potential customers you can review and contact.
5. Follow-up tasks keep the research moving without you having to
remember to check back.

FirstCustomer surfaces real, publicly posted discussions — it does not
fabricate customers, signals, or demand. What you see is what's actually
out there.

What’s new

First release.
FirstCustomer finds people who have already described your problem in their own words, and shows you which of them is worth talking to.
Describe your idea in a chat. We turn it into search terms, scan Reddit, and score what we find. Every signal carries the person's verbatim quote. No quote, no score.
Results start arriving in minutes, while the scan keeps running.
You send the messages. We never send anything on your behalf.
