Description
About Us
BigUp is building a new category of entertainment: Predictainment.
Attention has shifted from TV networks to creators, and prediction markets have transformed how audiences engage with live events.
We're building a platform that lets any creator launch their own TV network — think Twitch meets Kalshi.
Creators host livestreams supported by proprietary AI agents that handle production, clips, stats, and graphics, while fans watch and predict alongside their communities in a multiplayer experience.
We're a team of builders from Stanford, MIT, Circle, and Microsoft, backed by top-tier VCs and industry leaders from OpenAI, DraftKings, Whatnot, and Amazon Studios.
After a successful pilot this year, we're expanding rapidly into new markets — starting with NFL and college football, then non-sports verticals later this fall.
We're looking for an iOS Engineer to lead development of our iOS app and craft a delightful experience for our users.
