About Ketryx:

Ketryx is an AI software platform that enables healthcare life sciences companies to ship life‑saving regulated products in weeks instead of years.

Since launch, Ketryx already touches the lives of 100M patients and powers all of the world's top five medical device manufacturers. Backed by Lightspeed Ventures, our founders are the former Head of AI at Amgen and CTO of Wolfram Cloud.

Healthcare and life sciences is just the beginning for us. Automotive, aerospace, energy — if it's regulated, it's because society decided it matters. These products move humanity, shape our future, and are safety‑critical. Come join us and help build the AI platform to power safe innovation.
