What Bettors Are Saying
I've tried OddsJam and Unjuiced. SharpStack's EV tool is faster and the prediction market integration is a game changer.
The Pick’em optimizer alone paid for my subscription in the first week. The slip builder is insane.
Finally a tool that respects sharp bettors. Real data, real edges, no fluff.
Frequently Asked Questions
What is SharpStack?
SharpStack is 4for4's suite of betting tools. It includes a positive EV scanner, an arbitrage finder, a pick'em optimizer, odds and prop screens, a sharp money tracker, and a bet tracker that grades your closing line value. Everything runs in one place, so you can find an edge, place the bet, and track the result without switching between six tabs and a spreadsheet.
What is +EV betting?
Expected value is the long-run profit built into a price. Sportsbooks post thousands of numbers a day, and they cannot all be correct. When a book's price is better than the true, no-vig price of that outcome, the bet carries positive expected value and you are being paid more than the risk is worth. SharpStack calculates that true price from the sharpest markets and shows you exactly how much edge each bet carries.
How does SharpStack find these bets?
The model pulls live odds from 30-plus sportsbooks and exchanges, strips out the juice to derive true odds, then compares every available price against that number. Anything priced better than fair value surfaces in the EV Tool, ranked by edge. You can open the math behind any recommendation and see the fair odds we calculated, so you are never asked to trust a rating you cannot check.
Do I need to be a math person to use this?
No. The tools handle the math. EV percentage, Kelly sizing and arbitrage stakes are all calculated for you, and your job is deciding which bets fit your strategy. Every tool opens with a walkthrough wizard the first time you use it, and you can replay that tour anytime from the bottom left corner.

Can I use SharpStack for DFS and pick'em?
Yes. The Pick'em Optimizer prices every leg on PrizePicks, Underdog, DK Pick 6 and Sleeper against true odds, so you can see the edge on each pick and the expected value of the full slip before you submit it.
