Case Study: Illustrative Mathematics saves 50% on authentication costs with FusionAuth

Illustrative Mathematics Saved 50% By Moving To FusionAuth From Auth0

Illustrative Mathematics, a nonprofit K–12 curriculum and content organization, needed a cost-effective way to secure teacher-only content without exposing answers and assessment materials to students. The team had previously used Auth0, but authentication costs were too high for their mission-driven, open-access model.

Using FusionAuth Cloud, Illustrative Mathematics implemented login and access control for teacher content, along with custom admin and reporting integrations. FusionAuth helped them cut authentication costs by about 50% compared with alternatives, while also providing strong support and the flexibility their engineering team needed.
