About us

Real answers about ADHD shouldn’t take months.

Vextara exists to make objective, clinician-reviewed ADHD assessment fast, affordable, and available from home — closing the gap between a shallow online quiz and a months-long, thousand-dollar evaluation.

Our story

Built around access

If you’ve ever suspected you — or your child — might have ADHD, you’ve probably hit the same wall: free quizzes that don’t really tell you anything, or a specialist evaluation that means a long waitlist and a bill in the hundreds or thousands. Most people give up somewhere in the middle.

We built Vextara to be that missing middle step. It pairs the structured DSM-5 intake clinicians rely on with a short, objective attention test you take at home — then a licensed clinician reads the results against age norms and tells you what to do next. Objective evidence, a real human behind it, in days rather than months, for a fraction of the usual cost.

It’s the same philosophy the people behind Vextara have spent their careers on: meet people where they are, use real evidence, and make good care something you can actually reach.

What we stand for

Four things we won’t compromise on

Access first

Answers shouldn’t take months or cost thousands. We start from the question “how do we get this to more people, sooner?”

Evidence over opinion

Objective, norm-referenced data instead of a self-rating — so decisions rest on how attention actually performs.

A clinician behind every result

Software measures; licensed clinicians decide. There’s a human accountable for every assessment.

Privacy by design

Health-grade privacy, encrypted data, and no ad tracking. Your information is shared only with your care team.
