Sakana AI
Sakana AI is a Tokyo-based AI research lab founded in July 2023 by ex-Google Brain researchers David Ha and Llion Jones, pursuing nature-inspired methods — model merging, evolutionary optimization, and multi-agent orchestration — as an alternative to simply scaling one transformer architecture.
Sakana closed a $135M Series B on November 17, 2025 at a $2.65B valuation, then added Google, Citigroup, Salesforce Ventures, and Mitsubishi Electric as strategic backers through early 2026, becoming Japan's most valuable AI startup while shipping Sakana Fugu, a multi-model orchestration system, on June 22, 2026.
Think of Sakana AI as an AI lab that breeds champion racehorses by crossing existing bloodlines, rather than raising one bigger horse from scratch.

Why is it emerging now?
Sakana AI's Series B extension pulled in Google, Citigroup, and Salesforce Ventures as strategic investors through early 2026, and its CTO Llion Jones — a co-author of the original Transformer paper — went public saying he's "absolutely sick" of the architecture he helped create, right as the lab shipped its Sakana Fugu orchestration model.
Outlook
6-month signal projection and commercial timeline.
Japan's most valuable AI startup keeps compounding attention through funding and model-release news, not a single breakout moment.
Risk · Interest is announcement-driven and could fade between rounds if a rival Japanese or Chinese lab out-ships Sakana on model quality.
