API Hackday Austin - Where local startups connect before SXSW

Mashed by: @ajotwani

What is API Hackday? We started doing these sometime back in 2010 along with our Mashery API friends at SendGrid & Twilio with great success. It’s an event that brings developers together for an all-day coding fest focused on building apps with APIs. My personal past API Hackday outings have included Bloomington and my home turf - New York City held at our Mashery NYC offices. Developers of all experience levels can share ideas, collaborate on projects, start new ventures and discover great tools and new APIs to play with. The one-day format forces creativity. It rewards focus, minimalism and coolness. The format forces creativity and focus. The fact that you have a little less than 8 hours to do this makes very exciting. API Hackday events are like a hackathon, but leaner and built for speed.

This time it was Austin’s turn. Held at HubAustin on Saturday, February 18th - a fantastic co-working space in South Austin, run by Keith Casey and some of his friends, API Hackday Austin was a great experience. Even though it was drizzling all day, it certainly didn’t dampen the spirits of Austin developers. We had a great turnout

Some really cool apps got built in litte less than 8 hours. What’s more, Austin based startup - opened up their API for the weekend in order to get valuable feedback from API Hackday developers prior to their public launch at SXSW. divines a consumer’s psycho-social profile by scanning and analyzing social media activity using complex context-sensitive pattern-matching algorithms.’s api allows anyone to build applications and widgets enriched with this data.

[Update: launched their Public API at SxSW and has received huge traction since then] If you haven’t, you must check out their 1 to 1 Personality app. It’s pretty cool.

Had a great time at API Hackday Austin. My love for Austin would continue into SxSW a few weeks later, but that’s another post :) A huge shout-out to Keith & HubAustin for being such an awesome host and providing a setting that was ideal for a hackathon. Plenty of desks, whiteboards, monitors. Great food. Nice Apps. Met some really cool people - I am looking in your direction Keith, Saranyan, Emanuel & Jeff Linwood. Great fun. Again, I love API Hackdays.
