Our Students Love Us

"I absolutely loved the course and have been using the concepts in my own work.  Being able to provide actual data from assumption tests back to my stakeholders to show them how we arrived at our solution was a great benefit."
Cory Johnson
Product coach
"I've being working in Product for a long time and I've had the opportunity do lots of discovery, but I never had a 'process' to follow. This course gave us a practical framework to follow as a PM, and an important tool to help leaders who are mentoring teams."
Marta Duarte Teixeira
head of product
ambev tech
"I got a lot of value out of this course and have been using it across multiple teams. The course gave me great language and framework ideas for doing this work repeatedly and consistently which has then made it easier and lower-lift to do, can’t thank you enough for that!"
Mike Brown
Principal Product Manager
