featuresSakana AI’s Product Team turns the technology created by our research teams into products and delivers them to the world. Many of the questions we hear from candidates in casual interviews and throughout the hiring process turn out to be the same ones. In this article, we’ve gathered the Product Team’s culture and our answers to those frequently asked questions, based on interviews with team members.https://sakana.ai/inside-product-team/
featuresSakana AI, a Tokyo-based AI company, has released four products in rapid succession: starting with Sakana Chat in March 2026, followed by Sakana Marlin, Sakana Fugu, and Sakana Translate. Why is a company long known for research and development shipping products at this pace? And what vision lies beyond it?https://sakana.ai/product-development-interview/
featuresWe spoke with Sota Omura, who leads the product team as head of product development. The conversation ranged from how the team came into being, to the reasons behind the unusual release pace, a vision of a future in which humans and AI make decisions together, and an organizational philosophy of turning diversity into strength.https://sakana.ai/product-development-interview/

featuresSakana AI, by contrast, is run from Japan, so the core of its product-making is entirely here. For someone based in Japan competing in the global market, I saw a company born in Japan as a major advantage.https://sakana.ai/product-development-interview/
featuresAt the time, Sakana AI had two main teams: the Research team, which studies a wide range of technologies including the development of foundational AI models, and the Applied team, which puts those results to work solving problems for enterprise customers. I joined the Applied team; a product team did not yet exist. The Applied team’s work — walking closely alongside each client, one company at a time — creates value nothing else can. At the same time, from the Applied team’s earliest days there had been a discussion: couldn’t a product deliver the value of the same technology to many more customers at once?https://sakana.ai/product-development-interview/
featuresAmid all this, Ren Ito, our co-founder and chairman, approached me: he wanted to discuss how to treat model development as part of our own business. I presented a plan for growing a product business, model development included. As a result, the effort began moving as a partly independent offshoot of the Applied team. When the release of Sakana Chat was decided, we became a fully independent team to make the lines of responsibility clear, and I have led it since February 2026. Sakana AI, which began as a research and development company, is coming to wear the face of a product company as well. I feel I am standing at that turning point.https://sakana.ai/product-development-interview/
featuresAt Sakana AI, we are advancing world-class R&D through unique generative AI techniques inspired by nature. Our Product Team is on a mission to leverage our proprietary research to conceptualize and launch AI products that defy traditional boundaries. We are looking for a Business Intern to support this mission alongside our product managers.https://sakana.ai/careers/business-intern-product-team/
featuresThis is an internship position based in our Tokyo office, requiring full-time commitment (approximately 40 hours per week), for a minimum of six months, with a desired start within the next one to two months. This is not a shadowing role; you will own real operational work from your first week and experience firsthand how AI products are built, launched, and grown from Japan to the world.
