Evidence-based product design

Your students deserve tools backed by science

At Coral, we believe that impactful results are created through research and evidence, not by hunches or creative marketing.

That's why:
- Our first non-founder team member was a Chief Academic Officer, not a sales or marketing role

- We were named finalists in The Tools Competition, a Learning Engineering competition sponsored by The Bill & Melinda Gates Foundation, Schmidt Futures, and others

- We've signed the Research-Based Product Promise by Digital Promise and why we're on track to receive the Digital Promise Research-Based Design Product Certification

- We're on track to receive industry-recognized ESSA certifications and placement in the What Works Clearinghouse
