Our ds is currently on this path.
He is a second year MBA at the Stanford GSB. Support has been extensive, IMO. Stanford is hugely entrepreneurial in both course offerings and resources. He and his co-founder (who graduated from the GSB last year) took their Start Up Garage course last winter quarter. They raised significant funds last spring through Kickstarter for an industry demand study which was completed late this fall.
Ds received a Botha-Chan fellowship which enabled him to continue working on their start-up over a portion of the summer.
They are just now getting to the seed round stage. They have determined the amount they need to raise for next steps. To my knowledge, they are not going the accelerator route. I am not privy to all their inner workings at all.
As a parent, it is both exciting and nerve-wracking. But, I have told my ds that now is the time to take risks. Before returning to business school he had MBB and then FAANG (no idea what acronym is used now) employment. He didn’t go to b-school to check another, “safe,” box.
