TheraB Medical
Medical device startup acquired by Natus Sensory after developing SnugLit, an FDA-cleared wearable swaddle-style phototherapy product for neonatal jaundice.
What They Do
TheraB Medical developed SnugLit, a wearable phototherapy garment that treats neonatal jaundice while allowing parent holding, breastfeeding, and more normal infant positioning during therapy. The product was designed to reduce the separation and workflow friction created by traditional bili-light systems, and the company positioned it for hospital, home-care, and lower-resource settings. The company emerged from the Michigan State startup ecosystem and spent several years progressing through pre-seed and seed tranches before receiving FDA 510(k) clearance in January 2026.
Competitive Position
TheraB’s advantage was product-level differentiation rather than platform breadth: a family-centered phototherapy form factor in a market dominated by stationary lights and fiberoptic blankets. That made it highly complementary to a neonatal incumbent such as Natus, which could pair SnugLit with an existing newborn-care sales channel and move the product faster than an independent startup could on its own.
