“David and his team were an absolute pleasure to work with.  Their experience exceeded all expectations and was key to the success of the Winter 2019 YC Demo Day in San Francisco, our first offsite Demo Day.”

Demo Day

FiveEleven turned the raw space of Pier 48 in San Francisco into the first off-site venue for YC's 28th Demo Day – their largest yet.

In March 2019,180 companies from 35 countries gave 2-minute pitches to an exclusive audience of journalists and VCs over the course of 2 days on 2 simultaneous stages.

To ensure a flawless experience for this gathering of exclusive tech executives, FiveEleven brought in MIXhalo, a new audio platform that transforms the live event to create a personal, high fidelity audio experience for each member of the audience.
