Platform

One platform, from design to signal to decision

The SSI team and platform guide practitioners and researchers through the design and deployment of real-world data collection studies and evidence-based, personalized healthcare.

Deployment is facilitated through our Stations - a self-service point-of-care hub for pre- to post-intervention assessments in clinics, health centers, and workplaces - and our mHealth App, which extends these insights through continuous 24/7 monitoring of sleep, stress, recovery, activity, and other physiological markers in everyday life.

Our platform collects research-quality sensor data from tablet or smartphone onboard sensors and attached external wearable biosensors. Data is by design organized and stored in a safe and structured manner to support research and clinical standards. Our services support SSI-hosting or self-hosted solutions.

The SSI Approach

Translating physiology into human understanding

By connecting multimodal physiological sensing and real-world context with scientific rigor, SSI transforms complex data into meaningful insights for individuals, practitioners and researchers. The platform is built to evolve as new research, technologies and applications emerge.

The SSI Approach

  1. Practice

    Integrating personalized, evidence-based protocols

  2. Signals

    Multimodal data and wearables

  3. Patterns

    State-of-the-art analytics and AI

  4. Understandings

    Harmonizing scientific data with inner experience

  5. Better decisions

    Stronger insights, better outcomes

Three products, one platform

Meet clients where they are

Stations

In your clinic

Biofeedback during in-clinic sessions - no app, no subscription for your clients.

mHealth App

Between sessions

Continuous 24/7 monitoring for the clients who want to stay engaged and get the most out of their programme.

Live Biofeedback & Intercoherence

Live, together

Synchronises multimodal measurements across sensors, apps and participants onto one shared timeline, so an individual's physiology and the group's can be followed live.

Stations meet clients in the clinic. The App walks with them through their week. Together they make the bundle: you stay with them - and they stay with you.

* Multimodal physiological data means ECG, PPG, EEG, fNIRS and movement, recorded together rather than one signal at a time. SSI gathers these alongside contextual data (location, weather), behavioural data (sleep, steps), patient-reported data (questionnaires) and cognitive assessments (reaction time) - one picture of the person, not a stack of separate readings.

Analytics

Three levels of depth

Your center study reports - monthly and final - are included at every subscription, at full depth. They are what makes the data mean something, so they are never an add-on and never counted. What changes across the three levels is how deep the per-client analysis goes.

Basic

Free, unlimited, forever

Heart rate, HRV, RR intervals and core EEG metrics, with instant and daily reports for every client. Unlimited at every subscription - measure every walk-in without watching a counter.

Advanced

Deeper per-client analysis

Advanced EEG processing, comparison across sessions, statistical analysis and statistical power. Fifty advanced client reports are included each month; beyond that they are 15 DKK / 2 EUR each.

Custom

Built around your case

Bespoke algorithm development against your own question - a measure we do not compute yet, or a method your field expects. Start a conversation.

Deliverables

Concrete decision support, not just data

The deliverables are personalized reports and insights delivered to the practitioner, researcher, or end-user according to the chosen reporting frequency.

Instant session report

After each in-clinic session - biofeedback summary of HRV, breathing and brain activity, seen immediately.

Daily / weekly report

Continuous HRV trends, sleep quality and adherence, compiled from wearable monitoring.

Monthly study report

A provider's cohort overview - running results across all clients for ongoing decisions.

Conclusive study report

Auto-compiled scientific summary: design, N, methods, statistics - ready for white-paper polish.

Deployment

Two ways to host

SSI-Hosted

We run everything. EU-native, secure, GDPR-compliant, zero setup. Focus on your clients; we handle the data and the science.

Self-Hosted

The platform runs on your servers; your data never leaves your control. We deploy, migrate, validate and train your team. Built for researchers, hospitals and anyone with strict data-sovereignty needs.

However you host, sessions can also go live: the Biofeedback Engine streams many participants' signals - multiple sensors, multiple signal types - into one synchronized picture, on a screen in the room or on any phone with a web code. Not one number from one brand of sensor: the whole room, live.

Connected Sensor Ecosystem

Leading sensors, one unified platform

Sensors are supporting evidence, not the story. SSI integrates state-of-the-art biomedical signal processing and a study-analysis pipeline with leading sensor and monitoring technologies - across health, recovery and performance.

Muse, Oura, Apple Health, Polar, Whoop, Google Health, Movesense, Dexcom

Integrations expand continuously as the ecosystem matures.

Let's understand the human beyond the data - together.

Tell us where you want to go - your research, your clinic, your people - and we'll help you get there, grounded in science and centred on the person.
