Quell is building the future of fitness gaming. Our players get fit fighting their way through a game designed to push their physical limits while keeping them immersed in the action. Our wearable, the Quell Impact, adds real resistance, powerful haptics, heart-rate data and real-time action tracking to create a unique blend of real gaming and intense exercise.

The team is made up of passionate superstars from the likes of Square Enix, King, Meta, Paradox, EA, Sony, Nintendo, Microsoft, and Disney. We’ve sold $1.5m in pre-orders and raised many times that in funding from top-tier investors. Now, we’re gearing up for an explosive launch.

YOUR Mission.

You’ll own features from inception to delivery, solving challenging problems and making smart decisions.
