Many ideas in. The few worth funding out.

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.”
