I’ve spent over 25 years building new companies and products as a founder, CEO, CPO, advisor and investment banker. Currently, I'm doing a mix of consulting, teaching, and writing. A new initiative is Product Case Camp, where I meet with small groups of senior product leaders on a weekly basis for case-based learning. Most recently, I was the Chief Product Officer at Meetup. All opinions and writing on this site are my own.
My award-winning books are used by entrepreneurs and innovation teams around the world to improve how they learn from customers and vet their ideas.
If you are interested in my science fiction writing, which I publish under G.W. Constable, you can find that here.
