Founded July 2023 so been working on it a few years, it may fall short but they have the money and talent to be potentially decent.
But did they deliver anything yet? There are many startups with notable founders that are not being able to get models launched. And even if they are able to launch, so they get PMF. In case of Sakana, they clearly focus on the Japanese market an have buildup a good pipeline on sovereign AI. But similar to Aleph Alpha or to a certain extend Mistral, I don't see how they can keep up.
