CB Insights today named Ferrum Health to its ninth annual AI 100, showcasing the 100 most promising private artificial intelligence companies in the world.

“The AI 100 winners are future movers and shakers, taking big swings that will shape the future of AI,” said Manlio Carrelli, CEO at CB Insights. “This year’s cohort is pushing AI applications from emerging to emerged, working on everything from AI agents for complex processes to security and robotics. They’ve also zeroed in on new and promising technologies that might not be on the radar of many enterprises — multi-agent systems, novel computing and data curation approaches, and physical AI.”

“This recognition reinforces the growing demand for trustworthy, clinically validated AI in healthcare,” said Pelu Tran, CEO and co-founder of Ferrum Health. “We’re proud to help leading health systems deploy AI  with proper governance—bringing the promise of this technology into real-world care.”

The list recognizes early—and mid-stage startups that are leading the way in applying AI across industries and architectures. Our research team picked winning companies based on CB Insights datasets, including deal activity, industry partnerships, team strength, investor strength, employee headcount, and proprietary Commercial Maturity and Mosaic scores. We also dug into Analyst Briefings submitted directly to us by startups.

Ferrum Health is redefining how health systems access and scale clinical AI by providing a secure, private AI platform that works across diverse IT environments—from on-prem infrastructure to private and public clouds.

With a rapidly expanding marketplace of pre-vetted clinical AI tools, Ferrum Health enables these hospitals to evaluate and deploy algorithms in days rather than months.
