For a limited time, early-stage to Series A startups can apply for up to one year's worth of free Kiro Pro+ credits in three tiers: Starter (up to 2 Kiro users), Growth (up to 10) and Scale (up to 30).
Startups with active AWS Activate credits are not eligible, though Activate credits can be used for Kiro. Applications are reviewed on a rolling basis; approved credits are added automatically to your AWS account.
