A cloud data platform, built by Applied Research Works, that puts quality measurement, risk adjustment, and population health in one clinician-facing view - so payers and providers can finally read from the same page.
American healthcare has spent a decade trying to pay for outcomes instead of volume. The hard part was never the ambition. It was the data.
Cozeva exists because a health plan and a doctor rarely see the same patient at the same moment. The plan knows a diabetic member missed a screening; the physician, mid-visit, does not. Cozeva - the flagship product of San Ramon-based Applied Research Works, Inc. - is a real-time, cloud-based data platform built to close that gap. It gathers claims, lab results, and clinical records from many sources, reconciles them, and hands both payers and providers a single, current view of quality and risk.
The company was founded in 2012 by Yin Ling Leung, a community health educator, and Shaibal Roy, a computer scientist. That pairing - clinical need on one side, engineering on the other - still shows in the product. Cozeva does not just report on care after the fact. It surfaces care gaps at the point of care, where a clinician can actually act on them during a visit rather than reading about them in a quarterly summary.
The name is deliberate. Cozeva blends the French coze, a friendly conversation, with the Latin va, to move or go forward. A data platform named after a conversation is a fair description of what it tries to do: get two parties that usually argue over spreadsheets to talk from a shared source of truth.
Roughly 84 organizations across 30 states run on Cozeva - covering more than 25 million lives.
Its customers fall into three groups. Health plans use Cozeva to measure and report quality (HEDIS, Medicare Stars) and to reconcile risk revenue. Provider organizations - independent practice associations, medical groups - use it to track performance and close care gaps. Partners in life sciences, research, and public health build on the same data platform. Named users include the Integrated Healthcare Association, Western Health Advantage, Providence St. Joseph Health, Elevance Health, AltaMed, and Blue Shield of California, which in 2025 tapped Cozeva to help power a member-facing digital health record.
The problems it solves are the unglamorous ones that decide whether value-based care works at all: fragmented data that never reconciles, quality measures calculated too late to change anything, risk-adjustment codes that go uncaptured, and the mutual distrust that grows when a plan and a practice can't agree on what actually happened to a patient. Cozeva's answer is a shared, NCQA-certified system of record that both sides can inspect.
Illustrative emphasis based on Cozeva's published product focus and KLAS scoring; not an independent benchmark.
Cozeva packages its platform into payer, provider, and partner tiers - with EHR integration as the connective tissue.

EHR-integrated solution with demonstrated back-end integration to major systems like Epic - metrics and clinical data flow both ways.
Vendor partnerships, research, and public health programs built on the shared Cozeva data platform.
The value-based care software field is crowded. Cozeva's distinction is where it puts the data - and who it lets read it.
Cozeva competes in value-based care analytics against names like Innovaccer, Arcadia, Cotiviti, Reveleer, and Health Catalyst. It has grown less on venture headlines than on renewals - a retention rate above 95% is its real growth engine. Third-party estimates put annual revenue near $7 million and headcount around 280.
In October 2025, the company made its biggest move: a merger with Vatica Health, a three-time Best in KLAS winner for risk adjustment backed by Frazier Healthcare Partners. The logic is neat - Cozeva's top-ranked quality platform joins Vatica's top-ranked risk platform, plus Vatica's high-touch clinical services. Terms were not disclosed. Months later, in February 2026, Cozeva took its own 2026 Best in KLAS award for risk adjustment at the point of care and in-home assessments, posting a category-high 91.2.

Cozeva's edge is domain fluency - the intersection of clinical measurement, regulatory certification, and large-scale data engineering.
The company holds the certifications that healthcare data actually requires: NCQA HEDIS and RAF data capture, HITRUST, and ONC. Those are not marketing badges - they are the gates a plan must clear to submit quality and risk data to regulators, and Cozeva builds to them by default.
Leadership reflects the mix. CEO Khanh Nguyen brings 15+ years of payer-provider collaboration. CTO Rupinder Singh leads cloud and AI/ML work. CIO Amitava Maulik carries 30+ years in large-scale data systems. Co-founder Madhurima Dhar, an SVP of product development, remains a founding voice on provider engagement and EHR integration. Co-founders Shaibal Roy and Yin Ling Leung continue as chair and board members.
An advisory board rounds it out with figures from Blue Cross Blue Shield of Massachusetts, San Francisco Health Plan, and Asian Health Services - a deliberate tilt toward equity and public health that traces back to Leung's roots as a community health educator.
