About

Achievements

I have been one of fewer than 10 people in early-stage startups 7x times, and have helped create or scale organizations that have gone on to raise or be sold for more than $450m USD ($800m USD if you include companies I've advised). I wrote a book while building Chownow, and have released several open source projects that I use to support scaling services for users and revenue.

Some companies I've helped build or scale include: Networks in Motion/Telecommunication Systems, Adly, Chownow, Openmail/System1.
