Welcome to

For the first twenty years of my career, I (co)founded a series venture-scale software companies, growing each from an idea to a company earning millions in revenue, collectively serving tens of millions of customers.

I now use the knowledge gained from those twenty years to help new 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.

Accelerator & Investments

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

Africa Eats is an investment holding company focused on lowering hunger and poverty in Africa through for-profit solutions. The first spin-off of Fledge, it builds upon the work of a few dozen Fledge alumni who are building the food/ag supply chain across Africa.


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 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, such as:

The philanthropic investing service at Realize Impact, a 501c3 public charity that I co-founded, which lets any philanthropist turn a donation into an impact investment.

I hope something from this long list is of help to you.

Inside the Apple II4

Do you remember my journey down the 8-bit computing rabbit hole? Well… if you are going to do something for fun like designing an upgraded 1976 CPU and writing a 1979 personal computer operating system, you might as well go all the way and write the accompanying book too, in the matching late-1970s style. I read a lot of fan fiction in my free time, but I don’t recall ever seeing much...

Apple’s IPO, before the NASDAQ was a “real” market

Apple went public in December 1980. They successfully raised $100 million at $22 per share. They’ve split those shares 2:1 three times since then, and 7:1 once, and 4:1 once, plus they’ve bought back a lot of shares, but roughly that $22 share today is worth at least $40,000. If you read this blog, you know that rise in value isn’t what mosts interests me, but rather the fact...

Berkshire Hathaway listed in 1988!?

The more I dig into Berkshire Hathaway, the odder it gets. Did you know the company wasn’t listed on the New York Stock Exchange until November 1988? In 1929, Berkshire Fine Spinning Associates was created through the merger of the Berkshire Cotton Manufacturing Company (founded in 1889) with Oliver Chace’s textile companies (founded in 1839). In 1955, Hathaway Manufacturing Company...

Venture Capital Took Decades to Be Significant

It feels like venture capital has been around forever. Forever as in at least a few hundred years, if not thousands, no? No. Venture capital as talked about and practiced today has only been around since 1959. It is younger than my parents. And it wasn’t a $1+ billion industry until the 1980s, when I was in high school. This is part 2 of a series and will focus on that slow growth of the...
