A16Z, a private American venture capital firm, led a $20m Series A funding round in Knownwell, an in-person and virtual, weight-inclusive primary care and metabolic health company, with participation from Flare Capital Partners. "Obesity is perhaps our country's greatest healthcare challenge, from both a clinical and cost perspective. We are thrilled to back Brooke, Angela, and the team at knownwell as they leverage both technology and human care teams to allow every patient and provider nationally to access evidence-based, comprehensive, and ultimately high-value obesity medicine,” Vineeta Agarwala, A16Z General Partner.
