Nubrain is a neurotechnology startup developing foundation models for brain data, focused on decoding thoughts into text, images, and speech from non-invasive neural recordings. The company works at the intersection of machine learning, EEG and fMRI signal processing, and brain-computer interface development.

The company's technical team includes founding machine learning engineers with experience at previous startups and researchers with expertise in EEG, fMRI, and fine-tuning large models for neural data. The approach centers on building generalizable AI models that can interpret brain signals across modalities and subjects, moving beyond narrow, single-task decoders toward broad-capability brain-AI interfaces.

Nubrain's advisory board includes senior technical leaders from Vercel, Goldman Sachs, and Restack.io alongside neurosurgeons and academic neuroscientists from Maastricht University and Texas University. The company targets applications in assistive communication (thought-to-text for individuals with motor impairments), cognitive state monitoring, and eventually consumer-facing brain-computer interaction.
