The Auth0 for Startups program gives eligible early-stage companies one year of the B2B Professional plan for free, including up to 100,000 monthly active users and enterprise features. When the 12 months end you move to a standard plan.
Eligibility lists startups that are venture-backed with less than $5M in funding. The offer is not valid for existing paid Auth0/Okta customers or startups that were already in the program.
