You're probably building the wrong thing.
80–99% of ideas fail. Even at Google. The question isn't "can we build it?" — it's "should we bother?" We help you find out in weeks, not months.
20 minutes. You'll know if this is right for you.
4,000+ experiments since 2020.

THE PROBLEM
This is how most decisions get made.
→ 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 just the failed project. It's the winning idea that never got tested because someone had a stonger opinion.
THE REFRAME
The question isn't "Can we build it?"
"Should we build it?"
Pretotyping answers this question in weeks, for hundreds of dollars - before you spend months and millions. You test demand with real customers, measure what they do (not what they say), and get data to make the call.

“I've never worked with a company where we haven't saved them at least 100k in four weeks. Never.”

What clients say
Teams across industries use Exponentially to validate before they build.

“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 kill, 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. So teams are building, before asking if anyone actually cares.
As few as ~5% of AI initiatives deliver measurable impact. And up to 88% of AI pilots/POCs never reach production.
Not because the tech doesn’t work, but because success was never defined first.
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).
