Miami-based OpenEvidence, an ad-powered AI search tool for medical professionals, has reached a $15 billion valuation after two-thirds of US doctors began using it to scour clinical literature for patient decisions. The startup processed over 42 million prompts last month and has raised nearly $1 billion from top-tier investors including Andreessen Horowitz, Sequoia, and Blackstone. Its rapid rise has drawn both praise for easing physician workloads and scrutiny over result accuracy and competitive pressure from OpenAI and Anthropic entering the space.
Background
AI tools in healthcare have proliferated since 2023, with physicians increasingly adopting generative AI for diagnostic and treatment research. The intersection of ad-supported business models and clinical decision-making remains an emerging and controversial area.
