Summary

Beacon Biosignals, co-founded by Jake Donoghue PhD ’19 and Jarrett Revels, is developing an AI-driven platform to diagnose and treat neurological diseases by monitoring brain activity during sleep. The company utilizes a lightweight, FDA 510(k)-cleared EEG headband to collect clinical-grade brain data from patients in their homes, which is then processed by machine-learning algorithms. This approach aims to accelerate drug development, identify disease progression markers, and create patient cohorts for clinical trials. Beacon Biosignals has participated in over 40 clinical trials globally for conditions including major depressive disorder, schizophrenia, Alzheimer’s, and Parkinson’s disease. The company is building a "foundation model" of the brain from its growing dataset, aiming to characterize disease heterogeneity and discover novel subgroups over time. In 2025, Beacon acquired a sleep apnea testing company and raised $97 million to expand its platform and reach.

Key takeaway

For AI Product Managers developing diagnostic tools, consider how at-home, longitudinal data collection during natural states like sleep can provide unprecedented insights into disease progression. Your focus should be on creating scalable, patient-friendly devices that generate high-quality data for machine learning, enabling earlier detection and more precise interventions for complex conditions like neurodegenerative diseases. This approach can transform routine testing into a foundation for prognostic biomarkers.
