Break the chalk.
Win the tournament.
Monte Carlo simulation, AI-powered projections, and ownership-aware optimization. The DFS edge that costs $300/mo elsewhere — ours starts free.
No credit card required · Free tier includes Monte Carlo simulation
Every edge, one platform
Professional-grade DFS tools that were locked behind $300/month paywalls — until now.
Monte Carlo Simulation
10,000+ correlated simulations using Cholesky decomposition. Optimize for E[payout], not just E[points].
AI Autopilot
Claude Opus analyzes the full slate, builds strategy, and generates optimized lineups autonomously.
Ownership Leverage
Maximize tournament equity with ownership-weighted optimization. Fade the chalk, own the contrarian edge.
6-Factor Projections
Vegas, props, DvP, pace, minutes modeling, and injury redistribution. Fully transparent with factor breakdown.
Correlation Stacking
Empirical player-to-player correlation matrix. Auto-discover game stacks with bring-back optimization.
Contest Simulator
Model your lineup vs a 5,000-person field. See finish position, ROI, and payout distribution before you enter.
