Pupil-based neurofeedback: making mental processes measurable
MindMetrix is a Swiss neurotechnology company. We make the brain’s arousal system visible — and trainable.
Grounded in science, driven by research.
Our approach is grounded in hard science and driven by innovative technology. Changes in pupil size are a window into the brain's arousal system, controlled by the noradrenergic locus coeruleus. MindMetrix made this system accessible to volitional control — the discovery our company is built on.

Clinical application
Taking the same core technology beyond sport. A clinical application is in development with research partners and will follow the applicable regulatory pathway.
Coming soon →myflow
Pupil-based neurofeedback to measure and train mindfulness, focus and mental wellbeing — proven in elite sport.

MindMetrix is a spin-off of ETH Zurich and a venture of the Wyss Center for Bio and Neuroengineering in Geneva.
While our team of neuroscientists and engineers focuses on making pupil-based neurofeedback a trainable skill, our partners and investors provide the financial stability that ensures long-term commitment to the project.
Our location at Campus Biotech in Geneva, our roots at ETH Zurich and our multicultural team give MindMetrix unique access to international research, sport and clinical markets.

From lab discovery to everyday life.
What we already built
- 2018Discovery at ETH ZurichConcept born at ETH Zurich's Neural Control of Movement Lab. SNSF Spark Grant funds the proof of concept.
- 2018Scientific validationTraining method and its (neuro)physiological effects validated in multiple studies with 100+ participants.
- 2020ETH Pioneer FellowshipKick-start of the entrepreneurial journey: transferring the technology from lab to market.
- 2021Venture Kick · VR proof of concept · HMZ STRESSVenture Kick stage I & II. First proof of concept in virtual reality. Implementation partner in the Hochschulmedizin Zürich flagship project STRESS.
- 2022Incorporation · Bridge DiscoveryMindMetrix AG incorporated as an ETH spin-off with its first investor. 3-year Bridge Discovery grant with ETH Zurich and SFIS Magglingen.
- 2023Nature Human Behaviour · first productMeissner et al. show people can learn to self-regulate their arousal with pupil feedback. myflow, our first product, goes into pilot use.
- 2025Nature Communications · Innosuisse SIPWeijs et al. show pupil self-regulation modulates cortical excitability and LC activity. Startup Innovation Project grant awarded.
What we are doing now
- Clinical roadmap & validationDefining the clinical path for pupil-based neurofeedback and preparing validation studies with clinical partners, following the applicable regulatory pathway.
- Collaborations & joint studiesBuilding partnerships with clinics, universities and research institutes to run joint studies.
- Prototyping XR applicationsTesting our technology across different extended-reality applications and use cases.
Where we are heading
- Advanced arousal profilingGoing beyond a single signal: rich, personal profiles of how each brain regulates arousal — over time, in context.
- Integrated across XR mediumsArousal regulation built into the headsets and immersive experiences people already use — wherever performance and wellbeing matter.
