Founder 500 · Free lifetime access
Stop Guessing.
Start Winning.
Prop research on desktop and mobile.
Prop research starts with the full slate on the web app, then follows you into saved props, mobile checks, and daily tracking. Founder 500 members get free lifetime access across web and mobile.
Analysis only. Propeller does not accept wagers or operate as a sportsbook. Past performance does not guarantee future results.

Trust comes from visible work, not promises.
Every published result is tracked from model output to final outcome, so the record is visible before you start researching today's board.
Props analyzed and graded
Every model result is logged and graded against actual outcomes, giving the record real sample size.
Model win rate
Calculated from the live graded record, with pushes shown separately and excluded from the percentage.
Record refresh
The verified record updates from the same results system that powers Propeller's research workflow.
From open to answer in four steps.
Move from the full slate to a researched decision without bouncing between spreadsheets, odds screens, and stat sites.
Find the slate
Today shows what is live, what changed, and where the best opportunities sit.
Inspect the prop
The right drawer explains line, odds, confidence, movement, and model support.
Compare books
Users see where the best available number is instead of guessing across tabs.
Track outcomes
Watchlist and Tracker make research feel like a repeatable workflow.

Is Propeller a sportsbook?
No. Propeller is a research and analysis tool. We do not accept wagers or place bets for users.
What does the record include?
The current verified record uses the public graded-results API and summarizes analyzed props, model win rate, wins, losses, and pushes.
Why desktop and mobile?
The desktop web app is built for deeper slate research. Mobile is for quick checks, saved props, alerts, and digest workflows when you are away from the desk.
