AWS Activate Founders are Amazon cloud credits for a startup without outside investment: you start at $1,000 and some participants can get up to $5,000. The credits only pay for AWS services and are not cash in an account; when they run out you will pay yourself. For projects with a fund, accelerator or investor there is an Activate Portfolio tier of up to $200,000.
You need a pre-Series B startup founded in the last 10 years, with an AWS account on a paid plan, that has not received Activate credits before or asks for more than it received. The application is online with an answer in 5–10 working days; the internal evaluation criteria within a tier are not published.
