RadNet, the US outpatient diagnostic imaging group, announced on March 2, 2026 that it had acquired Gleamer, a Paris company that makes AI software for radiologists. Gleamer will be integrated into DeepHealth, RadNet's wholly owned digital health subsidiary.
The deal is an all-cash transaction valued at up to €230 million (about $269 million), including a post-closing milestone whose terms were not disclosed. RadNet said the price reflects Gleamer's multi-year growth in recurring revenue, its gross margins, its customer retention and the breadth of its product portfolio.
Gleamer's team of more than 130 people joins DeepHealth. RadNet said that with Gleamer, DeepHealth becomes the largest provider of radiology clinical AI solutions in the world.
What Gleamer built
Gleamer was founded in Paris in 2017 and is led by co-founder and chief executive Christian Allouche. Its first product, BoneView, helps radiologists spot bone trauma lesions on X-rays that are easy to miss, TechCrunch reported in 2023. The company later added ChestView for lung conditions and expanded into mammography, CT and MRI.
Its portfolio now includes four FDA-cleared and six CE-marked devices covering more than 25 indications in musculoskeletal, breast, lung and neurologic imaging. Gleamer says its software has analysed more than 30 million exams at more than 2,250 locations and has been the subject of 60 peer-reviewed publications.
The company sells its software through a cloud platform on a subscription model. It has more than 700 customer contracts with hospitals, imaging centres and health systems in 44 countries. RadNet said Gleamer's annual recurring revenue grew at a compound rate of more than 90% from 2022 to 2025 and is expected to reach about $30 million in 2026.
“Joining DeepHealth marks an exciting new chapter for our business and team members.”
Why RadNet is buying
RadNet operates outpatient imaging centres in nine US states and sells AI tools under the DeepHealth brand. DeepHealth already offered AI for breast, chest, neuro, prostate and thyroid imaging. Adding Gleamer gives it products across MR, CT, X-ray, mammography and ultrasound.
RadNet also plans to use Gleamer's software inside its own clinics. X-ray accounts for almost 25% of RadNet's imaging volume, and the company intends to build an AI workflow that first triages critical findings so urgent cases are read sooner. It also wants to speed up the introduction of draft reports, which it said would let radiologists read more studies with greater consistency. RadNet expects cost savings and improvements in patient care from these changes by the third quarter of 2026.
"As imaging volumes continue to rise amid an accelerating shortage of radiologists worldwide, reengineering high-volume workflows — particularly routine imaging such as X-ray, ultrasound and mammography — is becoming essential to sustaining access, efficiency and quality of care," said Dr. Howard Berger, RadNet's president and chief executive.
The combined business
Together, DeepHealth and Gleamer have more than 2,700 customer contracts in more than 50 countries, 26 FDA-cleared and 22 CE-marked devices covering more than 75 indications, and over 550 employees on four continents. The two businesses expect combined annual recurring revenue to approach or exceed $140 million by the end of 2026.
Allouche said joining DeepHealth marked a new chapter for Gleamer and its staff, and that combining Gleamer's AI, products and commercial team with DeepHealth's would let the company shape intelligent imaging at scale. Kees Wesdorp, chief executive of DeepHealth, welcomed Gleamer's team and said the deal brought together two businesses on strong growth paths.
The founders and the funding
Gleamer raised €27 million (about $29.5 million) in a Series B round in June 2023, co-led by Supernova Invest and Heal Capital, with XAnge, Elaia, Bpifrance, F3A, MACSF, Crista Galli Ventures, UI Investissement and several European radiologists taking part. TechCrunch reported at the time that the round brought Gleamer's total funding since its founding to €36 million.
French Tech Journal described the sale as a rare large exit for a French AI startup. Gleamer's investors were not named in RadNet's announcement, and the companies did not say how the purchase price would be split between the upfront payment and the milestone.
