Initial funding. There is a lot of growth non dilutive capital available but the first 500k are near impossible to get without a network in old money.
You used to raise that money through other local mittrlelstands. At the Masons lodge. At the local kiwanis or Rotary. But these have closed to young member decades ago when said younguns moved to uni degrees as a path in.
There is a lot of money idling out there to do that, but as Indie.vc showed, the usual LP are super frigid to it.
I do not have a good answer to this. The current young people simply are too unstable and too close to poverty to take the risks. And there is noone taking a risk on them either.
There is a looooot of value to make though. These markets are ripe for productivity enhancement through good software by small teams.
But the people that have the domain knowledge and the tech skills do not have the risk taking capability to execute.
Whoever find out how to provide them this will unleash massive growth on the world.
I advice to look at what calm fund is doing. https://calmfund.com/
The solution may end up being some kind of crowdfunding from other tech specialists with high income. Like FAANG devs.
