With starting a startup, some of the skills which you learn or demonstrate would be transferable I think. It depends on the type of startup for sure, but talking to prospective customers, design thinking for the product and getting the product to the market is something which is useful in many industries and something which companies will look for in a resume.
Can't say the same thing about esports since I am not familiar with the space.
Certainly some esports skills are transferable. There are (for instance): surface level things, low-level mechanics (e.g. CSing in MOBAs); larger strategies (e.g. team play, map movements, game sense); and meta-learning things, like how to learn games efficiently, take care of yourself, work with a team in the physical world, manage a career, etc.
it was tongue in cheek
Startup is relevant and marketable work experience. So usually accepted in other places in huge industry. Same skills doesn't necessarily carry from role to role inside a game or cross games. And spots for supporting personnel are less and have also other competition.
