Voio
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.
Adam Yala
Adam Yala is a UC Berkeley and UCSF assistant professor of Computational Precision Health turned founder, now CEO of Voio, a Berkeley AI startup building frontier radiology models. At MIT he created Mirai and Sybil, open-source AI tools that flag breast and lung cancer risk years early and are now studied at more than 90 hospitals across 30 countries. In late 2025 Voio emerged from stealth with $8.6M in seed funding and Pillar-0, billed as the most accurate open AI model for radiology, with a mission to make being a radiologist more empowering rather than to replace the profession.
