Yeah, there are quite a few notable startups and a strong community that is growing very quickly. Just had Startup Weekend in Orange County with another planned for March and one in LA in January.
I'm down in Orange County so I'm more involved in the community here with startups such as Mavenlink, Catchfree, and Drumbi. If you're going through LA, I strongly suggest stopping by Coloft.
If you have more questions or anything, let me know.
I was mainly wondering if there are notable startups that are based there and/or if there is a strong community of people working the startup life.
