Pretotyping — created at Google. Taught at Stanford. Embedded by Leslie Barry in 50+ enterprises.
AI made building almost free.
It didn't make choosing what to build any easier.
We train enterprise teams to validate ideas in days, not months, and hand over an AI system that keeps validating after we leave.
2 minutes for one idea. 20 minutes and we'll show you how to embed this across your company.

"The Pretotyping course saved our organisation $200,000 before lunchtime on day 2."
Dan Roesler
Executive Manager, PEXA Group
"Google born and Stanford finessed but perfected by you! Over 150 experiments run. If you're not already using Leslie's process, best get onto it."
Derrick Dicker
GM of Innovation, RACV
"Within the first 15 minutes, I could see there was something I'd been missing that I didn't even know I needed."

What this looks like inside real companies
50 pretotypes in 9 months
CEO-sponsored company-wide adoption across 300+ people. Millions saved by killing unvalidated ideas before they reached production.
Killed a bad idea in 3 days
Mocked up a website, ran 3 days of Google Ads, got zero uptake. Saved millions by not building a service nobody wanted.
Company-wide experimentation
Embedded rapid experimentation using pretotyping across the organisation. World-class methodology created at Google and perfected at Stanford.

How it works
Get in. Train. Embed. Get out.
Most clients start with training and a sprint. The AI platform keeps validating after we leave.
Training
One day to learn pretotyping. Your team leaves with a method they can use immediately.
Sprint
Two to four weeks running real experiments from your backlog. We work alongside your team.
AI Platform
An AI system that designs the next experiment based on every result. Ideas go in. Validated decisions come out.
Capability
Your team owns the method, the platform, and the confidence to keep experimenting without us.
About Leslie Barry
I've sat in your seat.
I've run innovation inside enterprises. I've built four companies, sold two, and learned expensive lessons from the other two. I know what it takes to get buy-in, navigate stakeholders, and make sure the best ideas get a real shot.
I trained directly with Alberto Savoia — Google's first Engineering Director and the creator of pretotyping. I'm listed as a collaborator on pretotyping.org, I guest-lecture at Stanford, and I've spent the last eight years turning a methodology into a system that works inside large companies.
Recently I rebuilt my entire platform using AI agents in 71 hours. It taught me that the hard part is no longer the building. It's still knowing whether any of it matters to the people using it.
Data > Opinion. Especially now.
Stop building things nobody asked for.
20 minutes. You'll know if this is right for you.
