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.

65%
of 4th graders in the US are behind grade level in reading.
42%
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.

Who We Are

We’re a tight-knit team with deep experience in K-12 education, childhood development, and technology, who came together to support parents in creating the best learning environment for their child.
