The Series B round attracted a mix of new and returning investors, including Japan's financial heavyweight Mitsubishi UFJ Financial Group (MUFG) and global venture firms like Khosla Ventures, Macquarie Capital, NEA, Lux Capital, and In-Q-Tel (IQT).
Sakana AI plans to use the new capital for R&D, including AI model development, as well as to expand its workforce for engineering, sales, and distribution teams in Japan. The startup has already expanded its presence in the country, partnering with leading local enterprises like Daiwa and MUFG, and developing AI solutions for their needs.
Looking ahead, Sakana AI aims to expand its enterprise business beyond the finance sector and into industries like manufacturing, industrial, and government by 2026. The company is also eyeing the defense, intelligence, and manufacturing sectors for potential growth opportunities. Sakana AI says it will be "actively pursuing strategic investment, partnerships and M&A for long-term global expansion.
