A clinical layer
for Mendi headbands
Mendi's headband is exceptional consumer hardware. EEGBase is an independent clinical platform that talks to it directly over Bluetooth — the same model Myndlift took with Muse. No Mendi app or cloud in the loop. Bring your own headband, plug it into a clinic.
EEGBase is not a Mendi product. We are not affiliated with, endorsed by, or licensed by Mendi AB. “Mendi” is a trademark of its owner.

The gap
What clinicians need that the Mendi app doesn't provide
The Mendi app is designed for consumers. Clinicians who prescribe or supervise Mendi-based neurofeedback sessions are flying blind — no caseload view, no documentation, no clinical accountability.
- 🗂️One dashboard showing every client and every session
- 📊See the full brain data — not just a single score
- 📋Track changes in mood, focus, anxiety, and energy over time
- 📝Write clinical notes tied to each session
- 🤖AI-generated clinical summaries for documentation efficiency
- 📤Shareable progress reports for clients, families, and referrers
- 🏥Billing codes, scheduling, and outcome measure tracking
- 💾EDF+ / CSV / PDF export for research and insurance
- 🔒HIPAA-friendly U.S.-hosted architecture — clinic-owned data, full export anytime
Open to collaboration · none active today
If Mendi ever wants to formalise a relationship
EEGBase will work with any Mendi headband regardless of whether Mendi wants a formal relationship — the integration is independent. The three structures below are options we’d be open to if Mendi ever wants to formalise something. Today, none of these are active.
Referral program
Mendi recommends EEGBase to clinicians who ask. EEGBase recommends Mendi to ours. Both sides get a referral cut. No code changes needed.
- Affiliate link in Mendi Pro onboarding
- EEGBase referral link to Mendi hardware
- Revenue share: ~10–15%
- Zero engineering required
Deep integration
EEGBase talks to the Mendi headband directly over Bluetooth — independent of Mendi's app or cloud. Clinicians see every client's sessions in one dashboard — even when the client trains alone at home.
- EEGBase consumer mobile app pairs with the Mendi headband over BLE
- Sessions sync to the clinician's EEGBase dashboard
- Per-clinician explicit consent in the EEGBase mobile app (GDPR Art. 9 / HIPAA authorization, revocable any time)
- EEGBase is sole data controller — no joint-controller agreement needed because Mendi's cloud is not in the loop
- Engineering owned end-to-end by EEGBase — no Mendi engineering required
White-label portal
EEGBase powers a "Mendi for Clinicians" branded dashboard. Mendi gets a B2B SaaS product and recurring revenue stream. EEGBase gets distribution to Mendi's clinician user base. Full co-brand or full white-label.
- Mendi-branded clinician portal
- B2B SaaS revenue for Mendi
- EEGBase provides ongoing development
- Revenue split: negotiable
Signal architecture
Built on Mendi signals
EEGBase already understands every signal Mendi broadcasts. Here's what each one tells clinicians.
Hardware: 660 + 805 nm wavelengths · ~31 Hz sampling · Brodmann area 10 (Fp1 / Fp2) · 2 long channels + 1 short-separation channel for skin-blood-flow regression.
Blood flow on the left side of the forehead. Goes up when someone is focused. ADHD clinicians track this during sessions.
Blood flow on the right side of the forehead. Tells you about emotional control and how alert someone is. Left-right differences matter clinically.
Tracks when oxygen is being used up by neurons. Helps confirm whether the brain is actually working harder, not just getting more blood.
Same signal on the right side. Used to compare left and right brain activity — useful for anxiety, stress, and trauma work.
Composite metric computed from OxyHb bilateral balance. Used for real-time neurofeedback. EEGBase preserves raw samples for clinical post-processing.
How the integration works
Independent BLE,
no Mendi engineering required
EEGBase reads the Mendi headband’s BLE GATT stream directly — the same approach Myndlift took with Muse. Mendi confirmed (May 2026) this is the supported model: no SDK, no licensing, no engineering effort on their side.
The adapter, decoder, Beer-Lambert helper, and unit tests are already built. The remaining work — capturing the GATT protocol from a physical Mendi via Wireshark — is being done in-house against the founder’s own headband.
Build status
Adapter scaffold (BLE transport)
MendiAdapter class — full GATT lifecycle, reconnect, control-char hook
Pure packet decoder
MendiPacketDecoder — separated from BLE I/O for unit-testing and mobile-app reuse
Beer-Lambert helper
Modified Beer-Lambert MBLL for the raw-intensity case (Wray 1988 extinction coefficients)
Unit tests
11 / 11 passing — preprocessed-Hb path, raw-intensity path, sequence-gap detection
BLE protocol capture
Wireshark + Android HCI snoop log against a physical Mendi (in progress)
Hardware-in-the-loop validation
Live session with real headband, baseline + serial-sevens task
