Watermark

Watermark Medical is a private sleep health technology and diagnostic services company focused on home sleep testing for obstructive sleep apnea and related sleep-breathing disorders. Its core offering is the proprietary ARES Home Sleep Test Solution, which combines an FDA-cleared diagnostic device with a cloud-based portal for data upload, analytics, workflow management, and reporting. The company serves physicians, dentists, hospitals, clinics, employers, and population health programs, positioning itself as a technology-enabled service provider rather than a therapeutics developer. Watermark Medical appears to operate commercially with a broad installed testing base and an emphasis on improving access, speed, and cost efficiency in sleep diagnostics.
