MultiCare Connected Care Taps Tuva Health to Optimize the Data of its 375,000+ Patients

MultiCare Connected Care, the accountable care organization of MultiCare Health System, selected Tuva Health to build, operate, and manage its enterprise healthcare data platform.

The partnership will support analytics across claims and clinical data for more than 375,000 patients across Washington state. MultiCare Connected Care will use Tuva to accelerate insights from its data and support care decisions across its population health and value-based care work.

The announcement also included a strategic investment in Tuva from MultiCare Capital Partners, the investment arm of MultiCare Health System. The investment made Tuva the first open-source healthcare data platform company backed by a health system and brought Tuva’s total funding to $6 million.

The partnership reflects a broader shift among health systems that want more ownership, transparency, and flexibility in their data infrastructure. Instead of sending data into expensive external systems that limit what internal teams can inspect or customize, MultiCare will operate on Tuva’s managed platform while retaining the benefits of an open-source model.

MultiCare’s internal data team will be able to customize the platform for its own needs while avoiding the cost and delay of building the entire foundation from scratch. Tuva’s open-source model gives organizations control over the data platform down to the code it runs on and can reduce implementation costs by 90 percent or more.

The announcement also noted that Tuva’s library of open-source algorithms and terminology sets is free to use, which can save organizations $500,000 or more annually. By adopting open-source infrastructure, MultiCare is helping demonstrate a path for other healthcare organizations to modernize data governance, security, risk management, and analytics operations without relying on black-box platforms.

MultiCare highlighted transparency and adaptability as central reasons for the decision. Previous platforms made it difficult for teams to reconcile and validate external sources of truth, and customization was often difficult. Tuva’s pre-built data marts for transforming and enriching data help MultiCare bypass a lengthy development phase and focus on tailoring the platform to its needs.

The partnership followed Tuva’s public launch with $5 million in seed funding and continued expansion across healthcare providers, payers, life sciences companies, and research institutions.
