Sakana AI

Sakana AI is Japan's most valuable AI unicorn, valued at $2.65 billion. Founded in 2023 by Llion Jones (co-author of the "Attention Is All You Need" Transformer paper at Google) and David Ha (former Google Brain researcher), the Tokyo-based company is building AI models optimized for the Japanese market.

Sakana's approach emphasizes smaller, more efficient models inspired by natural systems — the company's name means "fish" in Japanese, reflecting its philosophy of swarm-like intelligence over monolithic large models. The company is developing AI solutions for Japanese manufacturing, government, and enterprise applications, with a focus on models that work well with the Japanese language and business culture.

Sakana AI represents Japan's ambition to have a world-class domestic AI champion. The company's founders bring deep expertise from the very origins of the Transformer architecture, and their choice to build in Tokyo (rather than Silicon Valley) signals confidence in Japan's AI ecosystem. Sakana has attracted investment from major Japanese corporations and venture capital, and is expanding into enterprise AI services.
