1 x Co-author of the landmark "Attention Is All You Need" paper
1 x google researcher
20+ big name investors funding
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.
That paper had many co-authors and only two who were considered to be the primary drivers and geniuses behind (and they are american citizens).
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.
