Every NFL lineup, stress-tested against the real contest.
LineupIQ pairs projections and ownership with true contest simulation: your entries scored against up to 20,000 realistic opponent lineups and the actual payout structure, with stack correlations calibrated from seven seasons of NFL box scores.
Your entries simmed against realistic opponent fields and the real payout structure. Know your projected ROI before the entry fee.
Built for how NFL GPPs are actually won
Stacking, correlation, and leverage are the whole game on Sundays. Every piece below ships in the one LineupIQ plan.
Correlations from real box scores
QB-WR, QB-TE, and game-level correlations calibrated from seven seasons of NFL box scores (2019 to 2025), so stacks are priced by evidence, not vibes.
Stacks, run-backs, mini-stacks
Primary stacks, opposing run-backs, secondary mini-stacks, and exposure caps across your whole portfolio, all from one Stacks panel.
Your contest, recreated
LineupIQ rebuilds the contest you plan to enter: up to 20,000 opponent lineups modeled on real DraftKings fields, scored against the actual payout structure. Every build carries a projected ROI before you pay an entry fee.
Portfolio-level optimization
Optimizes bankroll results across every contest you enter at once, shrinking noisy ROI estimates before trusting them, instead of maximizing one lineup at a time.
Late swap that saves Sundays
Import your live entries, lock the players who already kicked off, and re-optimize the rest of every lineup for the afternoon slate.
Your projections, your rules
Use our projections or import your own as named sets per slate, and switch sources per build. DraftKings and FanDuel supported.

NFL questions
Which NFL contests does it support?
DraftKings and FanDuel, classic and single-game (Showdown on DraftKings, single game on FanDuel), from full Sunday main slates down to one-game primetime slates.
Can I use my own projections?
Yes. Import your projections as a named set for any slate and switch between sources per build, or blend with ours. Ownership projections are included.
How does late swap work on Sundays?
Import your live contest entries, and LineupIQ locks every player whose game has started, then re-optimizes the remaining slots across all of your entries at once.
How does the trial work?
New subscribers get 5 days of full access for $5. Nothing further is charged until the trial ends, and cancelling before then costs nothing more.
