Beacon Biosignals

Beacon Biosignals is a neurotechnology company applying machine learning to EEG (electroencephalography) to advance precision medicine for conditions affecting the brain. Founded in 2019 by Jacob Donoghue (MD, PhD) and Jarrett Revels, the company operates two lines of business: a life-sciences platform that collects, integrates and analyzes EEG across drug development and clinical trials (over 2 million hours of EEG processed across 40+ trials), and a home sleep testing business built on the SleepView Monitor and SleepView Direct platforms (500,000+ home sleep tests completed). Beacon acquired CleveMed in April 2025, and its Dreem 3S was authorized by the FDA in December 2024 as the first sleep wearable cleared with a predetermined change control plan. Beacon publishes no public REST API or developer portal; its public technical surface is a substantial open-source Julia ecosystem under the beacon-biosignals GitHub organization, including the Onda signal-data format, the Legolas schema framework, EDF.jl and Lighthouse.jl. Backed by General Catalyst, GV, Takeda, S32 and Innoviva.

Beacon Biosignals is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Neurotechnology, EEG, and Brain Health.

Beacon Biosignals’ developer surface includes documentation, engineering blog, support, changelog, and 15 more developer resources.
