Sadly you can't, and this is a huge flaw in the venture capital model. They invest in people that they think other vcs will invest in. More often than not who your parents are matters more than anything (unless you've had a huge exit like the OP). They'll also throw money at you if you come from a rich family, not because they think you'll succeed, but because they want your family's money as LPs in their funds.

Well regardless of whether it's hard or impossible, I'm doing this. I'm going.

The problem they have is that they're betting git is a solid foundation to build on. A tectonic change like git actually being replaced wouldn't just eliminate their moat, it would leave them trapped on the wrong side of it.

I can't win their game, so I'm changing the game.
