Welcome to
    Circle.

    Trust infrastructure for healthcare.
    There is no X-ray for the mind. We make the care you deliver undeniable to the payors who fund it, starting where proof is hardest.

    Mission & Beliefs.

    The proof of care
    is as important as the care itself.

    Nowhere in healthcare is proof more challenging than in behavioral health. Whether care is covered is subjective, adversarial, and varies from state to state. Providers speak clinical, while payors speak actuarial. Nobody built the layer in between.

    Both founders saw that gap firsthand. Keshav spent years building regulated infrastructure at scale, from SwaggerHub to emergency-response systems, and witnessed the same failure firsthand himself. Moe, on the other hand, was seventeen when his mother was denied prior authorization for a heart condition. The care was appropriate, but the proof was lacking.

    Co-Founder · Chief Executive Officer

    Keshav co-founded Circle Health after more than a decade building infrastructure products in regulated industries, where he repeatedly encountered the same gap in his personal experience. While great care was being provided, providers struggled to demonstrate it to payors. He was the first product hire for Swagger/OpenAPI and later served as Head of Product & Design at Prepared. Under his leadership, Prepared scaled from a handful of 911 centers into a national public-safety platform before its acquisition by Axon. Keshav’s entrepreneurial journey began at the age of 19, where he used his earnings to fund a master’s degree in business and engineering at Dartmouth.

    Moe Chowdhury, Co-Founder and CTO

    Co-Founder · Chief Technology Officer

    Moe co-founded Circle Health after experiencing firsthand the exorbitant costs of prior authorization. At the age of 17, his mother’s heart condition was denied coverage, compelling his family to make significant sacrifices. As a career software engineer, Moe has built infrastructure across healthcare and other highly regulated industries, including Walmart Pharma, Bausch Health, and Nutrien. At Nutrien, he developed platforms utilized by over 100,000 farmers worldwide. Today, he leads the technical infrastructure behind Circle, designed to securely scale sensitive clinical data.
