In case you missed it, SXTXState hosted its first hackathon just a few weeks ago to work on a mobile storytelling app using the Ushahidi platform. Most of us had never been to a hackathon before, but those who had said this was a very different environment from most.

For starters, at this hackathon, women outnumbered men 2-1. Kara Silverman of Hack’n Jill says that’s pretty rare because hackathons can be unwelcoming to women. It’s not that men who put on hackathons set out to exclude women, she says. It has to do with marketing.

Hackathons are often 24-hour events (not practical or particularly appealing for most women) with intense, competitive atmospheres. They even tend to be sponsored by brands that are marketed almost exclusively to men. What’s worse, Silverman says, is that when a woman does show up, she typically finds she’s the only woman there.

Hack’n Jill puts on hackathons that Silverman says offer welcoming environments for women without excluding men. She says having gender balance at a hackathon leads to a better product.

Silverman will join SoundCloud’s Dave Haynes, Voxy’s Jarod Reyes and Twilio’s Joel Franusic at SXSW Interactive on a panel exploring what happens After the Hackathon.

At the heart of this panel, Silverman says, is what you should do with all the creativity and energy, not to mention the finished product, after the event is over.

You can catch After the Hackathon at the Omni Downtown Tuesday at 3:30 p.m.
