Giff Constable

I’ve spent almost 30 years building new companies and products as a founder, CEO, CPO, advisor and investment banker. I was the CPO of Meetup until its spinout from WeWork and the CEO of Neo Innovation until it's acquisition by Pivotal.

Currently, I'm doing a mix of consulting, teaching, and writing. Two new initiatives include Product Theory, a podcast on product leadership available in audio or video. I'm also teaching a class on Financial Fluency for Product Leaders on Maven. 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.
