Welcome to
Circle.

Trust infrastructure for healthcare.
There is no X-ray for the mind. We make the care you deliver undeniable to the payers 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 covered is subjective, complex, and varies from state to state. Providers speak clinical, while payers speak actuarial. Nobody built the layer in between.

Both founders saw that disconnect firsthand. Keshav spent years leading product and engineering across enterprise software and national 911 emergency response networks, building mission-critical infrastructure where life-or-death systems could not fail. Moe was seventeen when his mother was denied prior authorization for a heart condition. The care was medically appropriate, but the administrative record lacked what the health plan needed to confirm it.

Chief Executive Officer

Co-Founder

Spent more than a decade building infrastructure products in regulated industries. Across those systems, he saw the same friction again and again: clinicians delivered great care, but had no reliable way to prove it to payers. He was the first product hire at Swagger/OpenAPI and later served as Head of Product & Design at Prepared, where he led its growth from a handful of 911 centers into a national public-safety network before its acquisition by Axon. He started his first business at 19 and used the earnings to fund a master’s degree in engineering and business at Dartmouth.

Co-Founder

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