Michael has also co-founded and served in leadership roles at numerous companies and nonprofits: Codeup, Effectual Ventures, Red Runner Coffee, Dry Line Partners, Near, and Alamo Angels. In total, these ventures have enabled over 1,000 new tech jobs in the San Antonio area over the past decade.

Prior to diving into San Antonio’s tech sector, Michael was CEO of Alamo Fireworks, the largest retailer of consumer fireworks in Texas for over a decade.  Under his leadership, the family business transitioned from 3rd to 4th generation leadership.

Academically, Michael’s background is rooted in technology.  He received a BS in Computer Science from Lafayette College (where he was a 4-year Division I swimmer).  Michael began his career in San Francisco, where he held engineering and marketing roles at RSA Security and BEA WebLogic, where, at age 25, he was the lead product manager for a $300mm business. 

In 2015, the San Antonio Business Journal named Michael “Man of the Year,” and in 2016, Geekdom presented him with their first-ever “Geek of the Year” award.  Michael has also authored several books on computer programming which have been translated into four languages.

His passions are his kids, his lovely wife, and growing San Antonio’s startup ecosystem.
