About

Build in public shows how you build. Marketing in Public shows how you get customers.

The most useful marketing knowledge isn't in marketing blogs. It's scattered across founders' posts on X, Reddit, Indie Hackers, LinkedIn, podcasts and newsletters — usually as a sentence or two, without the numbers that would make it useful.

Marketing in Public structures those stories into experiments: the channel, the tactic, the budget, the duration, the results and the lessons. So instead of “Reddit worked for me”, you get what was tried, for how long, for how much, and what happened.

Editorial rules

1
We never invent numbers.
If a founder wrote “got a lot of signups”, the signups field says Not disclosed. No estimates, no rounding up, no filling gaps — not by a person and not by AI.
2
Every experiment has a source.
Each one links to where the founder shared it — a post, thread, article, video or their own submission — so you can check it yourself.
3
The flops count.
What didn't work is a required part of the story. It's what separates evidence from advice.
4
Promotion needs evidence.
Founders are welcome to market their products here — with a real experiment attached. “Check out my SaaS” isn't one.
5
Sponsored is labelled.
If a placement is ever paid for, it says Sponsored, and it still passes editorial review first. Paying never publishes anything.
