BURL Concepts

BURL Concepts is a private, pre-revenue medical device startup based in San Francisco, founded in 2020. The company is developing the SONAS® system, a portable ultrasound-based platform combined with a microbubble solution, designed to non-invasively assess and monitor cerebral blood flow in real-time at the bedside. Its primary target is the stroke diagnosis and monitoring market, seeking to offer a cost-effective alternative to more expensive and less accessible imaging modalities like CT perfusion or MRI. The technology is not yet available for sale in the United States, indicating it is in a pre-commercial stage, likely seeking regulatory clearance.

Competition includes large medtech firms offering advanced CT and MRI perfusion imaging, as well as other companies developing non-invasive cerebral monitoring technologies (e.g., transcranial Doppler systems, optical methods). BURL must differentiate on cost, portability, and ease-of-use.
