The doors to TechCrunch Disrupt NY 2016 opened May 9 at the Brooklyn Cruise Terminal. The three-day conference hosted 2,300 attendees and hundreds of thousands more tuning in online. Indeed, Disrupt NY 2016 was the first media conference to stream on Facebook Live in full, making it one of our most watched events ever.

In the much-anticipated Startup Battlefield, 22 competitors pitched to a panel of judges in hopes of winning the Disrupt Cup and the $50,000 Grand Prize. TechCrunch editors pored over the judges’ notes and, after hours of deliberations, narrowed the list down to six finalists: online kid safety service Bark, interactive Twitch alternative Beam, Blockchain credit startup for emerging countries BitPagos, daily vitamin maker Ritual, underwater drone SeaDrone and ultra-affordable water filtration system WaterO.

Beam took home the grand prize for its platform that ties in with the growing world of e-sports to offer a low-latency chat platform for live streamed games. Beyond that, Beam lets viewers actually interact with the games by measuring the general intent of all the comments to play along with the live streaming gamer. You can think of it as a Twitch WePlay that actually works. WaterO was the runner-up.
