It's like Confabulator only for venture building

Build School teaches you to build. You can ship an app in a weekend now.

Once you have done the Claude Code course, building is the easy part. The hard part is figuring out what is worth building, and who will pay for it.

FounderOS is the missing half.

How it works

It flips the usual order. You start with an audience, not an idea.

1
Pick your people

Choose an audience you can reach and actually want to help.

2
Find where they hang out

The forums, subreddits, newsletters and Slack groups they already read.

3
Learn their pain and their language

Read what they write. Save the quotes. Notice the problems that keep coming up, in their words.

4
Ship small, useful fixes

Guides, checklists, tiny tools, given away. 30x500 calls these e-bombs. You develop deep customer empathy and earn trust before you ask anyone for money.

5
Launch something you already know will sell

By now the product falls out of your research. You know who it is for and how they describe the problem.

Stages are gated. Complete one, the coach reviews it, and the next stage unlocks once it passes.

The superpower immune to obsolescence from AI

Historically software engineering has been the hard part but the time and cost of building apps is headed towards zero with AI.

This creates a flippening where now understanding a market well enough to know what to build and who will pay for it becomes the most difficult skill.

Worried AI will make you obsolete? This is the skill that not only is timeless but compounds. Once you can find a market and sell into it, you can do it again, and again, and use your vibecoding experience to deliver each product you know will sell.

The muscle you are building is the ability to mine publicly-available information and refine that knowledge into products that sell.

What you get

A roadmap that takes you through the journey

A system known to work if you stick to it. One well thought out, linear gated path, with a coach to lead you through each step of the way.

Invaluable tools, skills and strategies that you own

A browser extension for capturing any valuable input you read. A 24x7 coach that learns your biz and paces you through the venture building process.

A group of peers going through the same process

Accountability and support a community of peers all doing the same work. Office hours, cowork days, monthly dinners, quarterly retreats and Discord as the glue.

Questions

How is this different from Confabulator?
Confabulator turns an app idea into a build plan. FounderOS sits one level up. It helps you find the market and the customers before you commit to building the app.
Do I need an idea first?
No. You start by picking an audience. The idea comes out of the research.
Do I need to know how to code?
Not for the research. When it is time to build the product, that is what Build School is for.
Is it free?
Anyone with a free account can read every stage. The coach, card reviews and the Chrome extension are for paying members.

Find the market first.

Then build the thing it is asking for.
