Turn brainwaves into better treatment decisions.

A 10-minute EEG assessment and clinician dashboard for concussion and mTBI — objective recovery data you can act on at every visit..

Diagnosis happens quickly. Healing takes months — and you can't see it.

Symptom checklists stop showing change after about two weeks, while measurable brain deficits persist.
That leaves you treating a recovery you can't see.

Make brain healing visible at every visit

Circl pairs a 30-second-setup EEG headset with a 10-minute test your patient completes in the app. It captures the P300 — a brainwave response backed by 60+ years of peer-reviewed research — and returns a Brain Score and five metrics before the patient leaves the room. Because the test is fast and the subscription is flat, you measure every visit and see the whole recovery trajectory.

Clinical neuroscience, built for a therapy clinic — not a lab

Research-grade EEG has meant six-figure systems, a trained technician, and up to two hours per test. Circl brings the same validated signal into a normal clinic visit — no technician, no gel cap. Any trained staff member can run it.

How it works

Brain recovery changes week to week. Circl measures it at every visit — so you can see what's actually healing and what your treatment is moving.

Fast enough to fit the appointment you already have.

Take the test. Establish a baseline.

Your patient completes a 10-minute visual game in the Circl app. Setup takes 30 seconds — the headset goes on like a hat.

Track changes over time

Test at every visit and watch each patient's recovery trajectory against their own baseline — the trend a symptom checklist can't show.

Every reading is documentation for charts, payers, and referrals.

Understand what’s changing

See a Brain Score plus five metrics — brain power, brain speed, alertness, focus, and memory — and log symptoms and treatment against every reading, so you can tell which interventions moved the needle.

The subscription pays for itself in about three days

A flat monthly, no per-test fee. Clinics are reimbursed via CPT 96132 (~$122/test) and legal firms (~$150/test), and the busiest run about 140 tests a month per headset — roughly $10,000–$15,000 in monthly reimbursement. Test more, earn more, at no added cost.

Reimbursement varies by payer, jurisdiction, patient plan, and clinician credentials. Figures reflect what current Circl clinics report and are not a guarantee of payment.
