Most of these seem aspirational for YC to produce them and less of something that they can offer value to the entrepreneur. They can offer very little outside of SAAS style company that is tech for enterprise or tech for consumer. If you are looking space, arms, robotics, GovTech etc you are better looking for some corporate VC or another specialized accelerator. No one is truly a generalist.
But don't expect a corporate VC to be as fun or cool as YC.
