At Ello, we're on a mission:

To unlock the limitless potential within all children.

Millions of children aren’t getting the individualized literacy support they need during the critical early elementary years to succeed as learners.

of 4th graders in the US are behind grade level in reading.
of 8th graders are considered functionally illiterate.

To tackle this problem in a new way, Ello’s team is bringing together their expertise in AI, machine learning, education, business, and psychology.

We created Ello, the first-ever AI reading coach that works with real books to help struggling readers with evidence-based instruction & motivation.
