Khosla-backed Bunkerhill Health lets hospitals build their own clinical AI agents. At one health system, 20+ are live, triaging and routing patients.

Backed by Sequoia's Alfred Lin and Khosla Ventures, this startup is betting that healthcare's real AI opportunity isn't diagnosis—it's process.

Bunkerhill Health raised a $25M Series B led by Khosla Ventures, taking its total to $55M, to put healthcare AI agents to work inside hospitals.
