What to post when you build in public (and how to keep going)

By the LaunchPal team · Updated 21 October 2026

In short

Building in public means sharing what you ship, what you learn and your real numbers while you build. Post one small, honest update a week: what changed, one number, one lesson, one question. Small numbers are fine, people follow progress. Never show users’ data or secret keys in screenshots, and follow each community’s rules on self-promotion.

Building in public means sharing your app’s progress while you build it: what you shipped, what you learned, what went wrong and your real numbers. Some companies take it all the way. Buffer has published its finances and team salaries since 2013. You don’t need to go that far. A short, honest update once a week is enough to start.

It helps a first-time founder in three ways. People who follow your progress are the first to try what you launch. Every post is a chance to hear what confuses them before you’ve built the wrong thing. And it gives you a reason to finish something each week.

Seven kinds of posts that work

  1. What you shipped this week, with a screenshot. “Bloomly now reminds you when a plant needs repotting, not just watering.”
  2. One real number and what you learned from it. “Bloomly got 14 sign-ups this week. 9 came from one Reddit comment, none from the launch site.” Small numbers are fine. Made-up ones aren’t.
  3. A decision and why you made it. Pricing, cutting a feature, choosing who the app is for.
  4. A mistake and how you fixed it. These are often the posts people remember.
  5. Something a user said, with their permission. What they love, or what confused them.
  6. A question for your followers. “Would you rather get a reminder by email or by notification?”
  7. How you built something. The prompt that finally fixed a bug in your builder, or the setting you didn’t know existed. Other builders save these.

Where to post

You can share one update in several places. Adjust the first line for each one, and give each place its own link so you know which one brought sign-ups.

When building in public feels hard

What never to show

A weekly update you can reuse

Keep a few notes during the week, then turn them into one post: what changed, one number, one lesson and one question.

Prompt to draft your weekly update

Turn my notes from this week into a short build in public post. Start with the most interesting thing that changed, include one real number from my notes and what I learned from it, end with a question for readers, and keep it under 120 words. Write like a person talking, no hashtags except one at the end. My notes:
