Since its establishment in 2023, the Japanese startup Sakana AI has rapidly increased in value to over $1 billion, becoming the fastest startup in Japan to reach unicorn status. The founder David Ha worked at Google, and he co-founded Sakana AI with his former colleague Llions Jones.

Ha said that in the current AI field, many companies are collecting massive data and building large models, which usually consume a lot of energy. But Sakana AI has taken a different path, aiming to integrate existing and emerging systems to develop what they call "collective intelligence."
The name of Sakana AI, "sakana," means "fish" in Japanese, reflecting their inspiration from nature. Ha mentioned that in nature, organisms from ants to humans solve problems through cooperation, and the goal of Sakana AI is to keep its AI programs running continuously by combining the best of multiple systems, allowing them to operate at lower performance even when some services are interrupted.
Sakana AI has not only received support from the US chip giant NVIDIA but also established partnerships with several banks and companies in Japan, helping them advance in the rapidly developing field of generative AI. Ha believes that in Japan, the scarcity of resources makes it less likely to succeed in creating energy-intensive data centers, so their team has adopted a more flexible strategy.
The current team of Sakana AI has more than 100 people, mainly located in a shared office space in Tokyo. The company's tools include a Japanese chatbot called "Little Sparrow," which can work offline and protect user privacy. In addition, they have developed an AI tool based on historical Japanese literature that can respond to text queries in the style of a samurai.
Although Sakana AI's projects have some issues in certain aspects, Ha said that experiments are inevitable. Sakana AI has been working with MUFG, a major bank in Japan, for years, focusing on developing bank-specific AI systems. They hope to find a balance between cutting-edge AI research and providing effective AI solutions for Japanese companies and public sectors.
With the rise of the AI investment boom, Ha also predicts that this excitement will gradually fade, as every major technological revolution is accompanied by a bubble. He emphasized that although speculative investments carry high risks, they are also a source of funding for fundamental breakthroughs.
