I don't know if it's still the case but a few years ago all major cloud providers were easily giving away thousands of dollars in cloud credits. I expect them to stop this soon since smaller cloud players build on top of them and offer better dx and startups prefer to work with these smaller companies despite free credits from larger players.
As a startup boy we are happily chewing through hundreds of thousands in GPU credits across all major cloud platforms + lambda labs.
And once those credits run out we are planning to expand our owned training hardware. Currently we just have 3x L40S but would expand to 32x L40S. I’m excited to now be a sys admin in addition to a full stack web dev.
Largely enterprise spend. Startups are a different market segment. They initially have small budgets, and eventually fail or grow large enough to move to different products.
