BranchLab has raised $26 million in Series A funding led by McKesson Ventures, with participation from FCA Venture Partners, Sanofi Ventures, and AIX Ventures, announced in a press release. The round brings the company’s total funding to $35 million.

BranchLab provides an AI platform that helps pharmaceutical companies identify, segment, and activate patient and healthcare professional audiences. The platform enables teams to act on aggregated, privacy-safe data in near real time, improving marketing efficiency and reducing reliance on manual processes.

At the core of BranchLab’s system is a transformer-based architecture that trains models within customer-controlled environments. Only non-sensitive demographic and media data are deployed, allowing faster and compliant activation of campaigns. The company reports that its platform has delivered an average 70% improvement in marketing efficacy across multiple therapeutic areas.

With the new funding, BranchLab plans to expand enterprise deployments, strengthen integrations across healthcare and media systems, and continue developing its unified AI platform for pharmaceutical commercialization.
