Put teachers first
We believe teachers are the hosts of rich classroom environments—and the savvy engineers who turn instructional resources into learning outcomes. We build to support the hundreds of decisions they make every day.
About Eddo
More than 20 years ago, a science teacher started asking how technology could help him make sense of student thinking. Eddo grew from that question—and we're still following where it leads.

The beginning
Matt's physics classroom · 2002
Our story
Matt loved student sensemaking. Keeping up was the challenge.
The scale of student-generated artifacts and daily instructional decisions only grew as he mastered the mechanics of the classroom. When AI arrived, making sense of all that sensemaking suddenly seemed within reach.
He began testing ideas with real teachers and co-designing with professional learning communities. Through constant classroom experiments, iterations, and adjustments, Eddo emerged.
Today, Eddo transforms student artifacts into an assessment loop with actionable insights and instructionally aligned feedback. It's a tool built by teachers, at home in the classroom, and shaped by educators every step of the way.
We're still early. Still learning. And we'd love to have you be part of what comes next.
What guides us
Our values keep us focused on people as we drive to solve problems.
We believe teachers are the hosts of rich classroom environments—and the savvy engineers who turn instructional resources into learning outcomes. We build to support the hundreds of decisions they make every day.
Knowledge shared is knowledge multiplied. The best ideas in teaching spread from teacher to teacher. We learn from our community, contribute to it, and grow through belonging to it.
We believe in high agency and communicate with candor. By sharing our points of view while listening with respect, we create an innovative power strengthened by our differences.
Exploration drives us. We seek answers, keep learning, and open ourselves to evidence that challenges our assumptions. We hold convictions firmly—and revisit them when the evidence changes.
Every decision we make aspires to create student-centered moments. If it doesn’t move the needle for learners, we don’t build it.

Teacher curiosity, applied to building.
