Last spring a neighbor of mine (researcher/professor) was talking about how one of his students stumbled upon one of these SBF foundations and that prompted them to apply. The application process was a Google Form and within a few days they got a $1M grant. No questions or interactions outside the Google Form. The only restriction was something to the effect that the it had to be spent 100% on the research project and the university couldn’t take any of the money to cover its own expenses (or something to that effect).

He was amazed at how swift and low-detail it was as he’s generally spending most of the year flying to conferences, visiting/speaking to foundations etc to pull the funding together.
