There is lots of awesome happening all over SF, the city is alway bustling with parties and there are endless places to go with an influx of people coming to the city and leaving the city.
For me this is both a blessing and a curse! There is always something to do, but this environment makes it really hard to find and make new friends. SF is a transient city and all the years I've been here the most meaningful friendships come out of work friends.
We are building an app that helps connect with the people around them to do fun things and get to know each other, and we call it Wigwm (for context, a Wigwam is large building where Native American's would all come together to eat and build community). On Wigwam folks can post events so they can find people around them to share experiences. A perfect use case is someone just moved to SF for work and wants to check out a new bar in their neighborhood next thursday. They can post an event at the bar and say they are looking for 3 people to check out happy hour with them. Or go to the park, check out a concert, get some ice cream at bi-rite, play a game of pickup basketball.... there are lots of options here, but I think you get the point.
What it is: crowdsourced event platform
The space: meetup.com & eventbrite.com for user generated events. Sosh, UpOut, SFstation, FunCheap for curated content (ton's of these guys out there).
How are we different: hyper local with a focus on small groups meeting around shared interests, super simple visual single page app and user generated content.
