Polygon, a startup that offers virtual evaluations for learning differences like ADHD and dyslexia, emerged from stealth Friday with $3.6 million in seed funding.

The seed round was led by Spark Capital and builds on a previously unannounced pre-seed led by Pear VC. In total, the company has raised $4.2 million.

WHAT IT DOES

Polygon provides remote learning assessments and screenings for conditions like ADHD, dyslexia and autism. The startup said clients between the ages of 7 and 50 can access its services. 

Its targeted psychoeducational evaluation for reading and cognition costs $495, while its most in-depth assessment for attention and learning differences is $2,745. 

WHAT IT'S FOR

Polygon said it will use new investment to continue to develop its platform and to expand geographically. It currently operates in California. 

"I wasn't properly assessed and diagnosed as very dyslexic until later in life, well after my early education years. Polygon is my attempt to create the service that I wish I'd had access to as a child," the company's founder and CEO Jack Rolo said in a statement.

"The capital we've raised has been used to build our proprietary assessment platform. We're thrilled with the progress, but we're just getting started. Further platform development, additional services and national expansion will help us provide gold-standard learning differences services to the mass market."

MARKET SNAPSHOT

Another company that provides remote learning assessment and support is Parallel Learning, which launched in December with $2.8 million in funding. Since then, the startup has hired new members for its leadership team and expanded into Illinois, Texas and Florida.

Cognoa, which is focused on digital diagnostics for behavioral health, received FDA De Novo clearance last summer for Canvas Dx, its software designed to help primary care clinicians and pediatricians evaluate and diagnose suspected cases of autism among children.

Other companies focused on learning and attention differences include Akili Interactive, which makes a video game-like digital therapeutic for kids with ADHD and recently announced plans to go public, and Mightier, which announced it had scored $17 million in Series B funding in December.
