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.

Proof: AGL saved $7.5M+ · RACQ stopped a multimillion-dollar idea in 3 days · Tabcorp avoided $12M and added $7.3M in new revenue.

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.

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.”

The 10 methods

Evidence, not opinions.
