Neko Health raised $700 million in a Series C to support expansion in the U.S., with the round co-led by Lightspeed Venture Partners and O.G. Venture Partners and participation from major growth investors. The financing underscores continuing capital appetite for healthcare-oriented platforms as investors target scale and operational execution. Neko’s large raise signals that digital health and adjacent healthcare tech is competing more directly with pharma and med-tech for venture dollars, especially where regulatory and clinical workflow integration is central to product differentiation. The funding also suggests that market validation is shifting from pilots to nationwide deployment strategies. For biotech-adjacent innovators, the magnitude of the round highlights a high bar for traction and data-driven product performance when entering or scaling in the U.S.
