16 Jun

- The platform targets enterprises with pay-as-you-go and tiered monthly plans.

Sakana AI, a Tokyo-based startup, has launched Sakana Marlin, a B2B AI research agent designed to provide deep, long-horizon reasoning. Unlike rapid chatbots, Marlin runs continuous reasoning loops for up to eight hours, producing comprehensive 100-page strategy reports and executive slides. The platform is available immediately for enterprise clients, including corporations, financial institutions, and think tanks, with pricing structured in tiered plans and a pay-as-you-go option.
Marlin operates as a self-contained digital strategy team, formulating hypotheses, gathering data, and verifying findings. It functions more like a junior strategy consultant than a search engine. The technology is powered by Sakana's Adaptive Branching Monte Carlo Tree Search (AB-MCTS) engine, which balances exploring new hypotheses with exploiting promising ones. This engine was notably released as open-source software in June 2025 under the name TreeQuest.
The commercial product, Sakana Marlin, extends AB-MCTS to a Multi-LLM approach, dynamically selecting and coordinating various AI models for specific sub-tasks. This ensures that the extensive reports are the product of systemic, automated trial-and-error. Sakana AI was co-founded in 2023 by Llion Jones and David Ha, who aim to move beyond the limitations of single, monolithic AI models by focusing on collective intelligence and biomimicry.
Sakana Marlin strictly adheres to an enterprise-grade data policy, meaning customer data is not used for model training without explicit consent. Licensing tiers include Pay-as-you-go, Pro, and Team plans, with custom Enterprise quotes available. The company secured significant Series B funding by late 2025, valuing it over $2.6 billion, attracting investments from major financial and tech firms.
