Braintrust ( is a user-controlled talent network, where you keep 100% of what you earn and actually get to own the platform. We've been onboarding some big clients and specifically need an experienced and well-rounded designer for this client.

About Our Client

We all make predictions. They occur with friends in bars and restaurants deciding who is going to win the game to boardrooms where executives decide which company to invest in. We all want to know what happens next.

Our client produces a prediction game where players are rewarded for being right.

They believe knowledge should be rewarded, and pays consumers for doing what they already do naturally every day: making predictions. It’s natural human behavior to predict the outcomes of things (ex: She is... definitely going to be the Bachelorette / There’s no way the Jets beat the Patriots), and our client enhances that natural behavior, rewarding players in the process.

To date, the game has over 3 million users and has generated over $8.5M in winnings, with $4M of those winnings being during the current COVID era (since March).
