I guess it is not very likely but I would suggest a solo scientists/innovator as the best candidate...

Near future AI systems, novel research methods and unique datasets (and a lot of luck) could let a single researcher make breakthrough advances. I am thinking of a room-temperature superconductor in materials science or a better transformer architecture in computer science, potentially yielding a billion-dollar patent or company, even if that’s beyond today’s AI system's capabilities.

The specific idea here is not important, the leverage of a new scientific advancement could be though.

Not every company needs to be a SaaS with focus on B2B that won't scale sufficiently for investors with one employee...

It could even be some rando on HN with weird ideas about computer architecture and security.

But it's far more likely to be someone who contracts out a lot of things, except for one core competency, and some really strong business networks, trade secrets or intellectual property.
