Sirona Medical Raises $40M to Expand Radiology AI Platform

Sirona Medical secured $40 million in Series D funding to bolster its AI-powered radiology software platform, RadOS. Avidity Partners led the investment, alongside 8VC, Great Point Ventures, KLT Holdings, and various other investors. The proceeds will solidify the company's long-term prospects and accelerate the adoption of RadOS, which unifies image archiving, diagnostic viewing, reporting, worklists, and workflow AI.

Since its debut in November 2023, Sirona has grown across numerous integrated sites, securing contracts with dozens of customers and handling over 12 million imaging exams annually.

Sirona's RadOS aims to simplify the integration of disconnected radiology practices within a unified cloud. By streamlining workflows, the platform seeks to assist providers in managing the surge in imaging volumes while addressing staffing challenges. Sirona's commercial execution highlights expanding customer adoption, with the average new-customer annual recurring revenue over the past year standing at $1.07 million and the mean total contract value at $5.10 million. Half of Sirona's customers already utilize its shared RadOS infrastructure.

The company's latest funding will also support the commercialization of Sirona Cortex, an agentic AI orchestration layer designed to extend automation across radiology workflows. To bolster its global presence, Sirona is establishing new US offices in Burlington, Vermont, and Cincinnati, Ohio, alongside enhanced customer support. Additionally, the firm plans to launch Sirona Global, expanding its footprint into the UK, European Union, South Africa, New Zealand, and Australia before the end of 2026.

Founder and President Cameron Andrews expressed confidence that the funding will enable Sirona to deliver its vision at a global scale. CEO Ken Kaufman detailed plans to deploy RadOS in more practices, hospitals, and health systems. The company will also release a series called "Built on Sirona," featuring customer case studies and technical insights into RadOS architecture, aiming to showcase how radiology providers leverage the platform to tackle operational challenges.
