I joined Swoop Srch while attending the University of Wisconsin - Madison. A friend who was already working there showed me the concept for a new search UI and I was immediately hooked. The first app was an apartment search app, and I had just had a frustrating apartment hunt. The UI concept was new and interesting, with the ability to rank each search term for importantce. There was a series of dots representing each search term placed on a circle. The user could drag each dot closer to the center to signal that term was more important. For example, to search for a "2 bed, 2 bath, for $1200" would create 3 dots, and you could rank the number of bedrooms as the most important more easily.
This was my first foray into startups and I quickly learned a lot. Most importantly, I learned how to ship a product quickly to start gathering user feedback, so we could iterate more quickly.
