Welcome to

For the first twenty years of my career, I (co)founded a series venture-scale software companies, growing each from an idea and a starting team to a company earning millions in revenue, collectively serving tens of millions of customers.  All but the first of these startups are still in operations and a few acquired by Global 1000 companies.

I now use the knowledge gained from those twenty years to help the next set of entrepreneurs.  My goal is to have them increase their odds of success by not repeating the common mistakes that I and my peers once made.  I do this in many ways:


The Next Step series of books guides entrepreneurs step-by-step through the process of getting from idea to operational startup, breaking the paradigm of startup investing, and explaining years of lessons teaching entrepreneurship.


The Next Step: podcast shares the lessons from the books plus other advice, anecdotes, and interviews, all in bite-sized audio pieces.


Fledge is a global network of conscious company accelerators, providing intense guidance, mentorship, investment, and support for a small set of entrepreneurs.


Answering questions from entrepreneurs on Quora.

Plus in these various efforts, I do my best to uncover hidden assumptions, break investment paradigms, and seek solutions to income/wealth inequality.

And despite now writing checks to entrepreneurs, I still consider myself first and foremost an entrepreneur, and as such every so often I simply have to create something new.  Most recently that is investorflow.org, an online network gathering together all the world’s impact investors.

Hope something from this long list is of help to you.

When Statistics and AI Go Wrong

Long long ago in Pittsburgh far away I earned a Bachelors in Mathematics. I then spent the first twenty years of my career as a “techie”, using that math and Computer Science to analyze and make sense of the world. Every so often that experience is useful here in the real world. Often that experience leads me to be cynical of the use of statistics in the news, especially when the...
