FlipaClip - Backend Tech Lead

About FlipaClip FlipaClip is the world’s biggest animation app with over +90 million lifetime installs. FlipaClip turns any mobile device into an animation studio. Animated movies and shows require massive budgets, years of production, or the approval of a handful of studios to exist. That’s how the industry has worked for decades. Very soon, a blockbuster animated movie will be entirely produced by a 15-year old in her parent’s basement. On a phone. And it will be made and distributed for $0. We are on it.
