I'm sorry for being a bit OOT, but does anyone have a list of these kinds of things, sort of like "goodies to grab when I start my startup somewhere in the near future"? E.g free AWS/Google Cloud credits and stuff.

Not the one like $10 voucher, at least few hundreds or thousands. Cash is king esp in early stage, but you don't want to cut coupons as it'll distract you from building your product.
