This time we'll piggy back on SuperHappyDevHouse. The organizers were nice enough to accommodate a sub-meeting for startup founders. So you get two-in-one: attend SHDH and at the same time have a dedicated room for startup entrepreneurs.
SHDH is the most awesomest developer meetup in the Bay Area (http://superhappydevhouse.org/SuperHappyDevHouse21). And with more than 150 developers attending every month, the spectrum of interests is very wide. By singing up to the sub-meeting you reserve a spot in the cool entrepreneurs section :) And, it's easier to find people doing the startup thing like you.
At SHDH you get a really nice environment, free wifi, free snacks and drinks, and even a free dinner. It's simply a wonderful day to meet people. They do accept donations, though, to cover some of their costs.
If you're NOT doing a startup but still want to attend, SHDH is open for all. More info here: http://superhappydevhouse.org/SuperHappyDevHouse21
However, if:
1. You eat ramen at least twice a week :)
2. Your startup is everything you do. Or you're in the process of making it so.
3. You have a product already or at least a demo.
Then:
1. Sign up here so I can send you updates. http://www.facebook.com/event.php?eid=20982002600
2. On the event page post your news.yc username and a link to your startup (optional).
3. On the event day bring your laptop and be ready to show your product and get feedback.
