Medallion, a San Francisco company that sells AI-assisted credentialing and enrollment software to healthcare organisations, said on September 15, 2026 that it had acquired Andros, an NCQA-certified credentials verification organisation (CVO) that has checked providers' credentials for health plans, health systems, provider groups and telehealth companies since 2013.
Terms of the transaction were not disclosed. Bailey & Company acted as exclusive financial adviser to Andros.
Medallion said the combination brings more than one million providers across nearly 400 healthcare organisations and health plans onto a single credentialing platform. Andros customers will be moved onto Medallion's software over time rather than all at once, the company said.
What Andros built
Andros began in New York in 2013 as CredSimple, a cloud-based service that verifies the credentials of physicians and other healthcare providers for health plans, independent physician associations and telehealth companies. In January 2020 CredSimple combined with Glenridge Health, and in September of that year it adopted the andros brand for the merged company, according to AiThority. At the time founder and CEO Mike Simmons described andros as a single platform for recruiting, contracting, credentialing and directory management, and the company said it served more than 75 healthcare organisations, including three of the five largest US payers.
Earlier customers named by MedCity News included Oscar Health, Clover Health and Providers Partners Health Plan. As a CVO certified by the National Committee for Quality Assurance (NCQA), Andros carries out the primary source verification that health plans are required to complete before accepting providers.
“Our customers have pushed us for 13 years to make credentialing faster and more accurate, and we have delivered on that in a category where most people accept the status quo.”
The funding behind Andros
CredSimple raised a $14 million Series B in June 2019 led by Questa Capital, with existing investors Windham Venture Partners, which led its Series A, and Primary Ventures, which co-led its seed round, taking part. MedCity News reported at the time that the company had raised around $28 million in total. Questa managing partner Brad Sloan joined the board.
Andros did not disclose its headcount, revenue or any later funding at the time of the sale, and Medallion did not say what would happen to Andros staff or to the andros brand.
Why Medallion is buying
Medallion is led by founder and CEO Derek Lo. In August 2025 it raised $43 million in a round led by Acrew Capital, with Washington Harbour Partners and existing investors including Sequoia Capital, GV, Spark Capital and NFDG taking part, bringing its total funding to $130 million, Pulse 2.0 reported. At that point the company said it already served around one million providers. The round was announced alongside CredAlliance, a shared clearinghouse that lets health plans verify a provider once and reuse the result across networks, which Medallion estimated could save the industry $1.2 billion a year.
The company says it wants to run credentialing, payer enrollment, licensing and provider data management on one system for every organisation that handles a provider record. Buying an established CVO with long-standing health plan relationships gives it a larger base of payer customers to move onto that system. Lo said Andros had built trusted relationships with many of the country's top health plans over 13 years.
Andros customers will gain access to Medallion features including automated primary source collection, AI agents that contact providers and follow up on missing documents, real-time status tracking and credentialing specialists who work alongside the software.
Tighter rules for credentialing
The deal comes as health plans face stricter deadlines. Insurance Business reported that NCQA cut the maximum time allowed to verify a provider's credentials from 180 days to 120 days from July 1, 2025, and added a requirement to monitor all enrolled providers every month. Organisations that fail NCQA reviews in 2026 are being cited for not meeting these requirements, the publication said.
Medallion will continue to serve health plans, health systems, provider groups, digital health companies and telehealth organisations, the company said.
