The competition is getting fierce in Colorado Inno Madness.
More than 3,000 votes were cast in the last round and the result was a major upset: the winner of last year's Colorado Inno Madness bracket, Pie Insurance, failed to make it to the final four.
Amp Robotics is advancing to the next round instead and competing against three other Colorado startups after some tight face-offs in Round 3.
Sheets & Giggles, a favorite contender this year, failed to advance over Stackhawk, which was the biggest vote-getter this round.
