SOUND FAMILIAR?
This is how it usually goes…
→ Someone has an idea. They put together a business case.
→ The team does dot-voting. The loudest voice wins.
→ Six months and $2M later: nobody uses it.
→ Repeat.
The real cost isn't the failed project, it's the winning ideas that never got tested. What if you could test ten ideas in the time it takes to build one wrong one?
THE BETTER QUESTION
The question isn't "Can we build it?"
"Should we build it?"
Pretotyping answers this in weeks, for hundreds of dollars - not months and millions. Test demand with real customers. Measure what they do, not what they say.
Get the data to back your best ideas and move on from the rest.

“I've never worked with a company where we haven't saved them at least 100k in four weeks. Never.”
TRUSTED WORLDWIDE
What clients say
Teams across industries use Exponentially to find and validate before they build.
Digital Conveyancing
“The Pretotyping course and rapid experimentation saved our organisation $200,000 before lunchtime on day 2! This should be BAU in every leading organisation.”
Dan Roesler
Executive Manager & Customer Assets, PEXA
"If you want to be a fast-paced, customer-led organisation, you have to be thinking constantly about how you're going to expand and grow across all dimensions."
"Leslie has a deeply purposeful connection to the pretotyping philosophy and has done amazing work in industrialising the training, tools and methodologies."
"Leslie is a fantastic facilitator. So important to start with the problem you are trying to solve before you jump to solution mode."
"We can pick out ideas that we know have a better chance of success, and we are able to reduce so much wasted investment."
"The lecture not only gives a convincing argument why pretotyping is very useful in developing MVP, it also gives students practice guidance."
"From prototyping to pretotyping. A great look at new models of product development in the Australian Financial Review."
HOW IT WORKS
Training
Two days to learn Pretotyping. Your team leaves with a method they can use immediately.
Sprint
Four weeks to test real ideas from your backlog. We run experiments together.
Results
Data on what to stop, what to pivot, and what to scale. Proof it works for your company.
System
The Exponentially platform stays. Your team keeps experimenting without us.
Get in. Train. Embed. Get out.
First metric: Time to first experiment. How fast can we get data?
WHY NOW
Everyone's vibe-coding AI features.
There's a perfect storm happening. Tools make it cheap and fast to build almost anything - which means the teams that validate first have an unprecedented advantage.
Only ~5% of AI initiatives deliver measurable impact. The difference isn't better tech. It's defining success before writing code.
Pretotyping is the missing step between "I have an idea" and "let's build it."
Sources: MIT “The GenAI Divide: State of AI in Business 2025” via Fortune (showing ~5% success) and IDC/Lenovo via CIO.com (showing up to 88% of POCs never reach production).
About Leslie Barry
I've run innovation inside enterprises. I know what it takes to get buy-in, navigate stakeholders, and make sure the best ideas actually get a shot. I was Head of Innovation at Sportsbet and ThoughtWorks - I've sat in your seat.
That's why I trained directly with Alberto Savoia, and spent the last eight years building a system that actually works inside large companies. A method that gets your team running real experiments - and gives you the data to back the ideas worth building.
I've also built four startups, sold two, and learned expensive lessons from the other two. The data will tell you which ideas are winners. That's what this is about.
