About OverUndr

OverUndr is a sports tech startup building the operating system for the sports analysis content ecosystem. We provide sports analysts and creators with the tools to publish, manage, and monetize their insights on predicted game outcomes — giving subscribers a professional, centralized way to access and pay for premium content. OverUndr does not take bets or operate as a sportsbook. Instead, we’re the infrastructure layer that powers creator-led sports analysis insights — handling payments, subscriptions, and audience engagement all in one place. We’ve acquired our first creator and are continuing development to support onboarding and the arrival of active paying users in our upcoming beta. With this momentum, we’re expanding our development team to move quickly through the next phase of product buildout and live testing. Joining now means working directly with the founders to shape a live product, build for scale, and contribute to the early codebase that defines OverUndr’s long-term platform architecture.
