As leading U.S. firms like Google, OpenAI, and Anthropic accelerate their development of large language models (LLMs), a new wave of startups is emerging, carving out specialized niches tailored to specific industries, regions, and use cases. One such startup, Sakana AI, based in Tokyo, has recently made headlines by closing a significant Series B funding round of ¥20 billion (approximately $135 million), propelling its post-money valuation to $2.65 billion, an increase from a pre-money valuation of $2.5 billion, according to CEO David Ha in an interview with TechCrunch.
Founded in 2023 by former researchers from Google, including Llion Jones, Ren Ito, and David Ha, Sakana AI focuses on creating affordable generative AI models optimized for the Japanese language and culture, particularly effective when working with small datasets. This focus allows them to provide solutions that resonate with local users and businesses, a stark contrast to the broader, more generalist models being developed by established tech giants.
The latest funding round attracted a mix of both new and returning investors, featuring prominent Japanese financial institutions like the Mitsubishi UFJ Financial Group (MUFG) alongside notable global venture capital firms such as Khosla Ventures, Macquarie Capital, NEA, Lux Capital, and In-Q-Tel (IQT). “We plan to deploy the new capital for not only R&D, including AI model development, but also to expand our workforce for engineering, sales, and distribution teams in Japan,” Ha stated. This year, the company has notably expanded its presence in Japan by collaborating with leading local enterprises, including Daiwa and MUFG, to develop tailored AI solutions.
Strategic Expansion Plans
Ha, who previously led research at Stability AI and has experience at both Google and Goldman Sachs, also outlined Sakana’s ambitions for future growth. The company intends to broaden its enterprise business, expanding beyond the finance sector into areas such as industrial, manufacturing, and government by 2026. Additionally, Sakana is eyeing opportunities in the defense and intelligence sectors. Beyond organic growth, they are actively seeking strategic investments, partnerships, and mergers and acquisitions (M&A) to ensure long-term global expansion.

Their approach prioritizes R&D efforts on AI products after initial LLM training, allowing for the efficient building of advanced models specifically tailored to Japan. This deliberate strategy sets them apart from the race towards larger-scale AI models dominated by major players.
This recent funding comes just a year after Sakana’s Series A round, during which the company raised approximately ¥30 billion (around $214 million) at a valuation of $1.5 billion. With this latest round, the total amount raised by Sakana now stands at about $379 million, according to data from PitchBook.
As the competitive landscape for AI continues to evolve, Sakana AI represents a poignant example of how startups can innovate and provide tailored solutions that resonate with local markets. Their journey offers insights into the significance of cultural contexts in AI development, illustrating a broader trend toward more specialized and focused AI applications.
