I've been a software entrepreneur since I was 14. Video games, then graphics software, then internet marketing analytics, distance learning and then AI driven ad-tech. LinkedIn bio.

My ringside seat at the shitshow of ad driven tech made me question the wisdom of making all this stuff free. So I researched how we got here and what the future might be instead. Everything I uncovered is packed into my two books: Free Is Bad and the new TLDR edition at just 90 pages. An audio book is also available.
