Evidium

Evidium is a healthcare AI company based in San Francisco, California, that builds what it describes as world models for healthcare, aiming to make medical knowledge computational. Its approach projects individual patients onto a computable map of clinical states, the transitions between those states, and the causes of those transitions, positioning this as complementary to large language models: where LLMs discuss medical knowledge, Evidium models its dynamics. The company ingests trusted sources of medical evidence — clinical guidelines, published studies and care pathways — and integrates claims and utilization data to build patient-level models of current health states, then projects trajectories for disease progression, treatment pathways and associated financial impacts.

The platform is organized as a set of precision products built on a shared modeling foundation. These include quality and insight tools for clinicians and care teams and probabilistic forecasting products for medical risk-bearing organizations such as insurers, health plans and integrated delivery networks ("payviders"). Evidium emphasizes traceability: every prediction or insight is intended to be auditable back to the clinical evidence and logic that produced it, and the company frames its outputs as augmenting rather than replacing expert judgment, including grounding other AI agents in clinical dynamics. Its stated mission is to scale explanatory medical knowledge to support better decisions, research and care provision, enabling a learning health system in which science, practice and outcomes are more closely connected.

At the time of its Series A the company said it was expanding into further healthcare segments, including life sciences and broader payer-provider ecosystems, and preparing hires in AI research engineering, clinical science and business development.

Founding story

Evidium was founded by Carl Bate, who serves as Founder and CEO, and the company was founded in 2021 according to its investor Health2047. It has since assembled a multidisciplinary team of engineers, scientists and clinicians with backgrounds across healthcare, AI and applied research.

Business model

Evidium sells a software platform with multiple products aimed at distinct healthcare stakeholders — clinician and care-team insight tools and probabilistic forecasting for risk-bearing organizations — all built on a shared clinical modeling foundation. Public sources do not detail pricing or contracting terms.

Not disclosed in the available sources beyond the sale of platform products to healthcare organizations.

Traction

Reported growing demand from health plans and provider organizations at the time of the November 2025 Series A, with an expanding product portfolio and a stated performance record on quality insights with health systems that the company is extending to insurers and other risk-bearing customers. The company lists roughly two dozen team members plus a group of clinical, insurance, scientific and technology advisors.

Latest developments

In November 2025 Evidium closed a $22 million Series A and said it would accelerate product development, deepen clinical modeling capabilities, scale go-to-market operations, and make strategic hires in AI research engineering, clinical science and business development, while broadening its offerings toward life sciences and wider payer-provider ecosystems.
