CTO's personal experimentation/prototype team? Like mini skunkworks for experiments that benefit from and ought to have zero bureaucracy. That's what I'd ask for if I were high enough up the chain. "give me a 5 person squad of elites and the mandate to point them at anything at all."
I wonder what a researcher at the Office of the CTO at Microsoft does.
