Head of Growth

We're building a +EV sports betting platform that helps bettors find mispriced odds across bookmakers and bet with a real mathematical edge rather than gut feeling.

Behind it sits the same infrastructure we build for quant funds and hedge funds: high-throughput odds feeds with real-time data from hundreds of bookmakers.

We're bringing that edge to anyone aspiring to beat the market.

We move fast, speak plainly, and care more about results than titles.
