GTOkiller is an exploitative poker solver built on Mass Data Analysis (MDA). While GTO solvers compute strategies against a perfect opponent that doesn't exist, GTOkiller solves against how your player pool actually plays, measured across millions of real hands, and shows you exactly which leak...

Questions & Answers

As answered by people managing GTOKiller and Superstring.

What makes your product unique?

GTOKiller's answer

GTOkiller is an exploitative solver, not a GTO solver. GTO solvers compute strategies against a theoretically perfect opponent that doesn't exist in real games. GTOkiller computes the strategy that maximizes EV against the way your player pool actually plays, measured with Mass Data Analysis across millions of real hands. The exploitative layer is applied to the entire game tree simultaneously, and every deviation is auditable: you see the GTO baseline, the real population frequencies, and the exploit side by side.

What's the story behind your product?

GTOKiller's answer

GTOkiller was built by a small team of poker players and engineers in Spain who kept running into the same wall: hours of solver study that real opponents simply didn't respect. If the pool doesn't play GTO, a strictly better strategy must exist. They built the engine to compute it: mass data analysis over millions of real hands, turned into full-tree exploitative strategies with every number visible.

Why should a person choose your product over its competitors?

GTOKiller's answer

Compared to GTO solvers (GTO Wizard, PioSOLVER, GTO+): they teach you to play against an opponent that doesn't exist. Their exploitative features rely on manual nodelocking, which is theoretical, biased by your own assumptions, and limited to one node at a time. GTOkiller applies real population data to the full tree automatically, at roughly half the price of GTO Wizard's top tier.

Which are the primary technologies used for building your product?

GTOKiller's answer

A proprietary solving engine and a Mass Data Analysis pipeline processing millions of hands per pool, served through a web app built on Next.js and Google Cloud.

Who are some of the biggest customers of your product?

GTOKiller's answer

Individual online cash game professionals and regulars across Europe, North America and Latin America

How would you describe the primary audience of your product?

GTOKiller's answer

Online cash game regulars at low and mid stakes (NL10 to NL100) who already study with solvers but feel their study doesn't translate into winrate, because their pools don't play anything close to GTO. Today the population data covers GG Poker NL10 to NL50; since leaks depend more on the stake than on the site, players at the same stakes on other sites use it as a close proxy.
