The idea-validation system for growing teams

Most ideas aren't worth funding. We find the winning ideas.

How do you pick the best ideas? We test them with real customers, so you can invest in the best with confidence, and save on the rest.

How it works · You win either way

Many ideas in. The few worth funding out.

One system finds them: pretotyping (built at Google, taught at Stanford), Rapidly software, and expert sprints. AI drafts the first pass; your experts decide.

Why Exponentially

Not a tool. The whole system.

Pretotyping, the software, and the people who've run it 4,000 times, working as one. A tool can't decide for you. A consultant can't scale. We do both.

Pretotyping

Should we build it?

The proven test, built at Google and taught at Stanford.

Software

Rapidly

Drafts the first pass, runs the tests, tracks the evidence and the decision.

Sprints

Our experts

We run it with your team, turning ideas into customer evidence in weeks.

Training

You own it

We upskill your team to keep doing it without us.

Leslie Barry, founder of Exponentially
“Alberto Savoia created pretotyping at Google and taught it at Stanford. I trained directly with him, then spent years adapting the method for teams, where the hard part is not understanding the theory. It is keeping momentum after the workshop ends.”
