About Collectly

Collectly is a fast-growing healthcare technology startup working to modernize the U.S. healthcare financial experience through AI-driven automation. Every day, millions of patients and providers navigate a system weighed down by inefficiencies, administrative burden, and confusing billing processes. The result is more work for provider offices and more confusion and frustration for patients.

Collectly applies artificial intelligence to revenue cycle management (RCM) to automate workflows, streamline billing, and create clearer, more humane financial experiences for patients. Our work focuses on real, high-impact problems: accelerating cash flow for providers, reducing operational overhead, and improving patient interactions during critical non-clinical moments.

By simplifying billing and payment experiences, we help healthcare organizations focus on what matters most: delivering care.

We’re a hybrid team, with roots in Santa Monica and teammates distributed across the U.S. and Europe.
