Bitbrain Brain-Computer Interface

Overview

Bitbrain (formerly Liftware) is a Spanish neurotechnology company specializing in wearable brain monitoring solutions for medical, research, and consumer applications. Founded in 2012 and headquartered in Zaragoza, Spain with operations in San Francisco, Bitbrain develops high-quality EEG headsets and biosensing technologies used by leading research institutions worldwide[@bitbrain].

The company's origins trace back to its tremor-suppression technology (Liftware), which was acquired by Google in 2017. This consumer health focus evolved into a comprehensive neurotechnology platform centered on wearable EEG systems for both clinical and research applications[@bitbrain].
