Baba raises $40 million to accompany Medicare patients with human teams supported by AI agents

The New York startup, led by FirstMark with CVS Health Ventures, wants to make the personalized support of elderly patients affordable. It also publishes BabaBench, a benchmark of agents on long-term health approaches.

Founded in 2025 in New York City, Baba has announced a $40 million Series A round led by FirstMark Capital, with CVS Health Ventures and Valtruis, alongside General Catalyst, Genius Ventures and Ground Up Ventures already in the capital. The funds are to finance its clinical teams, AI research and partnerships with health insurers.

A "concierge" service made profitable by AI

Personalized support for complex patients has so far been reserved for wealthy families who pay a private care manager, due to a lack of funding in traditional Medicare. Baba assigns each patient to a dedicated team — care coordinators, social workers or licensed therapists — and entrusts the logistics to AI agents: synchronization of appointments with specialists, monitoring hospital discharges, home help, contesting billing refusals, finding housing or transportation assistance. The company says it has supported more than 10,000 patients and has more than 100,000 families on the waiting list; it was selected for the CMS's ACCESS model, planned for ten years.

At the same time, Baba publishes BabaBench, a benchmark that measures the ability of models and agents to carry out administrative health procedures on their own that take weeks to complete — contesting an erroneous bill, deciphering coverage criteria, filling out social assistance files — without prohibited clinical acts or health data leaks. The paper was accepted in a NeurIPS workshop.
