What our students have to say

Great Course for Learning Pretotyping

“Exponentially integrates Lean Canvas with Pretotyping to capture the ideas and experiment the ideas. Working through my own ideas on the Exponentially App and getting feedback from Leslie Barry is my own learning experience of getting out of the Thoughtland, getting Skin in the Game, and getting my own data.”

Great course!

“I can really recommend this course to anyone interested in a deeper dive into pretotyping. Whether you're a beginner who want to add pretotyping to your toolbox, or an experienced "market experimenter" who want to add a bit more rigour to your process I believe this course fits great for both just as well.”

Petter Hanberger

Thought Provoking Online Course

“The course material has thought provoking questions and is well supported by relevant examples. The online tool is very useful to iterate on content in preparation for the final exercise. The feedback from the final exercise was very helpful to progress the idea with future pretotypes. Highly recommended.”

Juan Ramon Sanchez Velar

Hear from Pretotyping’s creator, Alberto Savoia

Alberto's book, The Right It, is the industry-leading text on Pretotyping. But as Alberto says: books can only take you so far – the best way to take theory into practice is to have a coach and other learners around you. 

“I endorse this course, I recommend it, and I plan to participate so expect to see me there!"
