All startups are eligible for up to $150,000 in Azure credits. To unlock more Azure credits, ensure you complete the tasks in your verification checklist found on the Home page in Founders Hub.
Accounts with an Azure credit offer of $5,000 or less, can submit a request for more credits in Founders Hub. If you are approved for an Azure credit offer of $25,000 or more, your account is reviewed approximately 45 days before your credits are due to expire. If approved, your account is automatically granted more credits and time in program.
