Amazon says you can only use one AWS discount on your account, ever, so trying to find the best one before we sign up for our startup.
There are tons of AWS discounts for startups, which all offer various amounts of credit. The catch is that you can only use one deal, though, so you should make sure to pick the best one when starting out.
Amazon's own AWS Activate offers $15-100k in credit, depending on your company details and the VC firm or accelerator behind your startup. You do have to apply for access, though.
Otherwise, the best option is to get $5,000 credit, which Product Hunt Founders Club, Stripe Atlas, WeWork, Brex, and more offer: https://capiche.com/e/best-startup-deals.
