OpenEvidence, the Cambridge-born AI medical chatbot used by clinicians, has quietly turned its Miami relocation into a full-on Florida expansion. After moving its headquarters to Miami last year, the company is now beefing up its operational footprint across the state and leaning heavily on partnerships with medical societies to pull it off. For Boston's health-tech crowd, it is another reminder that some homegrown stars are heading south in search of bigger markets and friendlier partner networks.
As reported by Boston Business Journal, OpenEvidence launched in Cambridge and formally shifted its headquarters to Miami in 2025. The company is now expanding operations in Florida with help from a national medical society, on the heels of a string of product rollouts and partnerships that have boosted its profile with clinicians and hospital systems.
Funding, valuation and backers
Industry reporting shows OpenEvidence has raised roughly $700 million to date and closed a $250 million Series D in January 2026 that pushed its valuation toward $12 billion. The company’s rapid fundraising pace and steady stream of product launches have attracted heavyweight backers and strategic partners, per DotMed.
Medical society partnerships drive adoption
To win over clinicians, OpenEvidence has signed content-licensing and integration deals with major journals and medical societies. The American College of Emergency Physicians announced in December 2025 that ACEP clinical policies and educational materials would be integrated into the platform. "We are very pleased that the OpenEvidence platform will feature ACEP policies, point-of-care tools and educational materials," ACEP President L. Anthony Cirillo said in the group’s announcement.
Industry analyses list a broad slate of publishing and society partners, which the company says helps its rollout across specialties and states, per Clinical AI Report.
What it means back in Cambridge
OpenEvidence was founded in Cambridge and grew up inside Boston’s dense cluster of hospitals, labs and venture capital, a combination that helped it scale quickly. Local coverage of the company’s litigation and growth has kept it in the spotlight. While still based in Cambridge, OpenEvidence filed suit alleging corporate espionage against a competitor, a case that highlighted just how high the stakes had become for area startups.
Observers say the Miami move fits into a broader migration trend that Boston’s health-tech scene will be watching closely, per The Boston Globe.
OpenEvidence’s Miami expansion comes as the platform reports accelerating adoption. Company press materials show the system handled one million clinical consultations between verified physicians and its AI in a single day in March 2026 and has introduced new clinician-facing features. Those milestones, promoted through press channels, help explain why the company is investing in a larger Florida footprint and continuing to court national medical societies as distribution partners, according to PR Newswire.
