Company Overview

About INBRAIN Neuroelectronics

INBRAIN Neuroelectronics is a neurotechnology company founded in 2019 as a spin-out from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) in Barcelona, Spain. The company develops minimally invasive brain-computer interfaces built on graphene — a single layer of carbon atoms with exceptional electrical conductivity, biocompatibility, and transparency to MRI imaging. INBRAIN's graphene electrodes enable higher spatial resolution neural sensing and more precise, adaptive stimulation than conventional metal electrodes used in implantable neurostimulators.

Business Model & Competitive Advantage

The company raised €30M in a Series B round in 2024, with investors including Neurotech Capital and other European deeptech funds, bringing total funding to over €50M. INBRAIN's clinical strategy focuses on neuromodulation indications with high unmet need: Parkinson's disease, epilepsy, treatment-resistant depression, and obsessive-compulsive disorder. Its AI-driven signal processing layer enables closed-loop stimulation — the device reads neural signals, interprets them with machine learning algorithms, and adjusts stimulation parameters in real time to optimize therapeutic effect, personalizing treatment to each patient's moment-to-moment brain state.

Competitive Landscape 2025–2026

INBRAIN has achieved first-in-human implantation milestones and is advancing through clinical development under regulatory oversight in Europe. The company's graphene interface technology has applications beyond therapeutic neuromodulation — including brain-computer interfaces for motor rehabilitation and future neurocognitive augmentation — positioning INBRAIN at the frontier of both medical device regulation and emerging neural interface technology. The company collaborates with academic medical centers and neurosurgical teams across Europe to generate the clinical evidence required for CE Mark approval.
