Over the past two days, 21 companies have taken the stage at the Disrupt SF Startup Battlefield. We’ve now taken the feedback from all our expert judges and chosen five teams to compete in the finals.

These teams will all take the stage again tomorrow afternoon to present in front of a new set of judges and answer even more in-depth questions. Then one startup will be chosen as the winner of the Battlefield Cup — and they’ll also take home $100,000.

Here are the finalists. The competition will be livestreamed on TechCrunch starting at 1:35pm on Friday.
