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 each deviation attacks and how much EV it extracts.

Key features: - Full-tree exploitation: the exploitative layer is applied to the entire game tree on every street simultaneously, not single-node nodelocking - 3-strategy view: GTO baseline, measured population frequencies, and the EV-maximizing exploit, side by side and fully auditable - Real pool data with visible sample sizes per node and a public methodology for showdown bias correction - AI Coach anchored to the actual numbers of each node, not a generic chatbot

Free plan available. Paid plans from €39/month.

startbase.dev features and specs

  • Faster project setup
    Startbase.dev appears designed to help developers and founders quickly scaffold new projects with pre-built templates and boilerplate code, saving significant time compared to starting from scratch.
  • Focus on startups/MVPs
    The platform seems tailored toward entrepreneurs and indie developers who want to launch minimum viable products quickly, which can be valuable for validating ideas without heavy upfront investment.
  • Modern tech stack
    Such starter kits typically integrate current, popular frameworks and tools (e.g., Next.js, Tailwind, authentication, payments), reducing the need to research and configure these integrations manually.
  • Reduced boilerplate maintenance
    By using a pre-built base, developers can avoid reinventing common features like user authentication, billing, and dashboards, letting them focus on unique business logic instead.
  • Potential cost savings
    Compared to hiring a development team to build core infrastructure from scratch, using a starter template service can be more affordable for solo founders or small teams with limited budgets.

Possible disadvantages of startbase.dev

  • Limited customization flexibility
    Pre-built starter kits and boilerplates often come with opinionated architecture and design choices that can be difficult or time-consuming to modify for highly specific or unconventional use cases.
  • Vendor/template lock-in risk
    Relying on a specific boilerplate structure may create dependencies on certain libraries, patterns, or update cycles that could complicate long-term maintenance if the base template becomes outdated.
  • Learning curve for the specific stack
    If the chosen tech stack differs from what a developer is familiar with, there may still be a learning curve to understand and effectively customize the starter codebase.
  • Uncertain long-term support
    As a smaller or newer platform, there may be concerns about the longevity of updates, community support, and documentation compared to more established open-source alternatives.
  • Pricing transparency concerns
    Depending on the pricing model, users may find costs less transparent or harder to justify compared to free, open-source boilerplates available elsewhere in the developer community.

Questions & Answers

As answered by people managing GTOKiller and startbase.dev.

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.

How would you describe the primary audience of your product?

GTOKiller's answer

Online cash game regulars at low and mid stakes (NL10 to NL200) who already study with solvers but feel their study doesn't translate into winrate, because their pools don't play anything close to GTO. Also MDA-oriented players who run population analysis by hand and want it automated and turned into complete strategies.

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
