Join us for the culmination of Build School Cohort 3 as non-technical founders publicly demo the working applications they built from scratch - and then pull back the curtain on exactly how they did it.

Here's what makes this cohort special: every single participant started with zero coding experience. No computer science background. No engineering training. Just ideas, determination, and a willingness to figure it out.

And yet, tonight they're launching live products. Including iOS apps. And one of them built a collaborative multi-user feature using a technique that stopped us in our tracks.

What's Different About Cohort 3

Build School Cohort 3 is our biggest and most advanced cohort yet - seven participants, more sophisticated projects, and a level of technical ambition we didn't expect to see this early.

More Builders, More Momentum

Cohort 3 is our largest group to date. More perspectives, more peer learning, and more proof that this isn't a fluke. Seven people with zero coding background shipped working applications in 30 days.

iOS Apps

Several participants went beyond web apps and built for iOS. Native mobile applications. From non-technical founders. In a month.

Double-Shipping

Many participants completed their first app and started a second within the same cohort window. When the process clicks, it really clicks.

The Council of Models

One student developed a technique worth talking about on its own: using Codex to stress-test implementation decisions by staging a debate between AI models before committing to an approach. Codex and Claude arguing it out, refining the solution through disagreement. It's the kind of emergent methodology we didn't teach - it came from a builder who pushed the tools further than we expected.

What You'll See

This Demo Night has a different emphasis than previous ones.

We'll show you the apps they built but the demos are the opening act. The main event is the lessons learned.

Each builder will walk through their process: what surprised them, what didn't work the way they expected, what they'd do differently, and the counterintuitive things nobody tells you before you start building with AI tools. This is candid, practical, and directly useful if you're thinking about building something yourself.

Live Product Demos

Seven working applications, deployed to production. Real interfaces, real databases, real functionality - including iOS apps and collaborative multi-user features.

Lessons Learned Deep-Dive

The part that makes this event genuinely useful. Each builder shares what they actually discovered over 30 days. Not polished retrospectives. Honest, actionable takeaways.

Why You Should Come

✅ Get Inspired Seven people who couldn't code a month ago are demoing live apps tonight. Watch ordinary people—consultants, entrepreneurs, product thinkers—ship real software. No technical background required. Just proof of what's possible in 2026.

✅ Walk Away With Something Useful This isn't a standard demo night. The emphasis on lessons learned means you'll leave with practical insight into the building process—what actually works, what the traps are, and what the counterintuitive discoveries look like from the inside.

✅ See What's Achievable Thinking about building an app? This is an unfiltered view of the process from people who just went through it. Get honest answers about the tools, the challenges, and what it actually takes.

✅ Meet the Builders Talk directly with the cohort after demos. These are people just like you who decided to stop waiting and start building.

✅ Learn About Cohort 4 Build School Cohort 4 starts May 4th. This is your chance to meet the instructor (Sean), see the results firsthand, and decide if it's right for your project. Applications are open now.

✅ Celebrate With Us This is a community milestone. Come raise a glass to seven people who shipped real products and join Lisbon's most active builder community.

Who Should Come

You're a Great Fit If:

✅ You have an app idea but don't know how to code ✅ You're "vibe curious" about AI-powered development ✅ You want to see real examples of what non-technical people can build ✅ You're considering Build School for your own project ✅ You want practical, counterintuitive lessons from people who just shipped ✅ You want to connect with Lisbon's builder community

You don't need to be technical, and you don't need to be considering Build School. Just come watch, learn, and be inspired.

About Build School

Build School is an intensive cohort where non-technical founders learn to ship working MVPs using AI development tools like Claude Code and Cursor.

What makes it work:

Self-paced video curriculum you can complete at your own speed

Live office hours (Monday & Wednesday evenings) for hands-on help

Friday in-person cowork sessions in Lisbon

Small cohort size for direct mentorship

Culminates in Demo Night where you launch publicly

Cohort 3 ran March 9 – April 13, 2026. Cohort 4 starts May 4th, 2026. Applications are open.

FAQ

"Can I attend if I'm not technical?" Absolutely. That's the whole point. These demos show what non-technical people can build with the right guidance and tools.

"Can I attend if I'm not interested in Build School?" Yes! Come for the demos, the lessons, and the inspiration. No pressure.

"Will there be food/drinks?" Light refreshments will be available at Tribe.

"Can I bring a guest?" Yes, but both people should RSVP.

"What if I can't make it?" We'll record the demos and share them with our community.

"How do I apply for Cohort 4?" Start with Confabulator to define your project, then apply for Cohort 4. We'll have applications open at Demo Night.

The Bottom Line

Thirty days ago, these builders had ideas. Tonight, they have apps and the hard-earned skills for creating them.

Come see what's possible when you stop waiting for a technical co-founder and start building yourself.

These events are always free to attend, but if you get value from it please consider donating to our friends at Lisbon Project who are doing important, thankless work integrating displaced refugees in the Lisbon community.
