Our Story

1 in 5 people has a learning difference such as dyslexia or ADHD, representing 70 million people in the US alone. Polygon’s mission is to enable every person with a learning difference to reach their full potential.

We Help Polygons Thrive in a World Built for Circles

From schools to career paths, the prevailing systems have been built for the “average” person — the perfect circle.

However, people with learning differences are anything but average. Often, they have distinct weaknesses paired with undeniable strengths. They are polygons in a world created for circles.

At Polygon, we aim to change both the outcomes and the perceptions of people with learning differences. We think shapes are a great way to think about these conditions — rewriting the narrative to focus on differences, not disabilities.
