Best HealthTech SaaS Companies in United States
The 858 best HealthTech SaaS companies in United States in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Imaging Advantage.
The 858 HealthTech SaaS companies tracked here, all based in the United States, are ranked by disclosed equity funding and recent funding momentum. Total disclosed capital across the directory sits at $340M, and the spread tells a real story: Imaging Advantage alone accounts for $295M of that, which means the rest of the field is running lean. No unicorns in this cohort. That's worth sitting with for a second.
What you're actually looking at is a sector where funding is concentrated at the top and the mid-tier is grinding on smaller raises. ingagepatient ($14M), referwell ($12M), and Authenticx ($9M) are the next tier down, backed by accelerator money from Alchemist Accelerator, BAJ Accelerator, and MassChallenge. Coverage growth is flat right now, but the activity I'd watch is happening around digital initiatives, cloud security, and marketing automation platforms, which is where new executive hires are clustering this quarter. So the fundraising headline may feel quiet, but the operational layer underneath it isn't. Companies aren't scaling by check size here; they're scaling by how fast they can ship.
