Sam Altman on VCs: "The number of investors that actually show up and try to help you is unbelievably small. Josh Kushner (@JoshuaKushner), absolute MVP investor, unbelievable, has worked around the clock for what feels like years to help us. He's the only investor that I could point to that is proactively incredibly helpful all of the time. The constant, relentless all-in support is surprisingly rare…but I think founders really love that and it actually moves the needle."
