EnsoData

EnsoData is a healthcare technology company founded in 2015 and headquartered in Madison, Wisconsin. It develops artificial intelligence and machine learning software for sleep medicine, applying waveform AI, signal processing and PPG (photoplethysmography) techniques to help clinicians analyse sleep studies faster and more accurately, and to link diagnosis to therapy. The company's stated aim is to make healthcare more accurate, efficient and affordable; it notes that an estimated 80% of people with sleep apnea remain undiagnosed.

Its first product, EnsoSleep, is AI-powered sleep study scoring software that received FDA clearance in 2017 and reduces the time needed to score sleep studies by more than 60%. EnsoHST, a home sleep testing solution, uses FDA-cleared PPG technology to convert widely available consumer pulse oximeters into diagnostic tools.

The company operates in regulated, medical-device territory - its software falls under FDA oversight - and works across healthcare, diagnostics, home sleep testing and clinical decision support. It employs an interdisciplinary team of engineers, data scientists and clinicians, and has been remote-friendly since before distributed work became widespread. It has signalled interest in applying its technology beyond sleep medicine, including ICU monitoring and conditions such as heart disease, diabetes and neurological disorders.
