Voio is a Berkeley-based frontier AI lab building a unified reading platform for radiology. Spun out of UC Berkeley and UCSF, it develops the open-source Pillar family of models that interpret CT, MRI and X-ray scans across hundreds of conditions, aiming to help radiologists work faster without trading away accuracy. The company exited stealth in November 2025 with $8.6M in seed funding.
Bunkerhill Health is a San Francisco AI company building the 'system of action' for hospitals. Its Carebricks platform lets health systems create, share, and deploy AI agents that turn routine data - especially CT scans already sitting in the archive - into actionable clinical findings. Born out of Stanford's Center for AI in Medicine and Imaging, the company has racked up a string of first-in-class FDA clearances for opportunistic detection of cardiovascular and bone disease, and in 2026 secured a national CMS reimbursement pathway for AI cardiovascular analysis.
