But you're losing investors money not your own
E.g. I would rather go for 50% chance of 1 million USD than 11% chance of 1 billion USD.
The amount of personal investment it takes to get to the point of pitching investors is pretty low (and well lower than “already succeeded at your business” IMO; raising money is not in itself business success).
It was ridiculously low a few years ago; it’s still low and achievable as an investment for most anyone earning a western SWE salary and not living extravagantly.
