I can speak from experience when I say that Austin's entrepreneurial community is welcoming, supportive, and full of very sharp folks. You should definitely check out the Lean Startup group (http://www.meetup.com/Austin-Lean-Startup-Circle/). Our next meetup is a joint holiday mixer with a lot of other Austin groups (like Austin on Rails), and it promises to be a great way to meet a ton of folks.

Also, I'm not sure if you're looking for a workspace with a lot of people in the same position, but we've really benefited from participation in the Austin Technology Incubator.

Edit: why do I say folks so much?

How big is the Austin startup community? Austin seems like a hell of a lot nicer place to live than the Bay Area, but I'm afraid I'd miss the incredible magnitude of the support available to startups here.

You should hit up http://cafebedouins.com and http://opencoffeeaustin.org.

Love to meet Austin entrepreneurs. Send me a note and let's get coffee: LinkedIn is in my profile or marascio at gmail.

I can vouch for getting together with Louis. He and I have done coffee a couple of times now, and he's got a great perspective on everything from funding to really in-depth technical issues.

Congratulations, good luck, and reach out often and always if you need a nudge or support. Full disclosure: I've been in the same boat and have been threatening to jump. If you're open to it, I'd love to exchange a few emails.

ps, wasn't there a new incubator recently announced in Austin?

I'm in Austin, have a company that's tiny but growing and have a few friends doing startups. I'd love to help any way I can.

Email me! It's in my profile...
