This is a private group of CTOs who are responsible for software development within their companies. They are generally the senior most person responsible for custom software development, database design, database administration, web development, etc. In a recent conversation with a fellow CTO, we lamented about the fact that while there's very active software development and web development going on in Southern California and West Los Angeles, yet there didn't seem to be as much of a community around it. I've helped organize the Los Angeles CTO Forum for almost 10 years.
