Partnership strengthens Havas’ innovation strategy, providing premier access to the fastest-growing AI engagement platform in life sciences.

Havas today announced a strategic investment and partnership with Ostro, the trailblazing AI-powered engagement platform built for the life sciences industry. In a world where consumers and healthcare providers (HCPs) are bombarded with information about new healthcare treatment options, Ostro provides a personalized healthcare journey and serves as the AI interface connecting life science companies with the medical community and patients to drive better health outcomes for individuals and increased ROI for brands.

This milestone partnership marks a pivotal advancement in Havas’ ongoing transformation agenda, further reinforcing the Group’s leadership in data, technology, AI, and personalized content delivery. Ostro’s award-winning platform is trusted by a majority of the top 10 global biopharma companies—and adoption is accelerating both within the top 10 and across mid-sized pharma and emerging biotech. Ostro’s rapid expansion is driven by its ability to seamlessly integrate into both branded and unbranded HCP and patient digital experiences, enabling dynamic, agent-led personalized engagement—all while meeting compliance and regulatory standards in full, and with implementation in eight weeks or less.

Through this preferred partnership and strategic investment, Havas gains premier access to Ostro’s platform across its entire global ecosystem. It will support Havas Health Network clients, with plans to expand across Havas Creative and Media Networks—fueling smarter content workflows, omnichannel activations, and enhanced media precision. Ostro’s capabilities have already extended into medical affairs, with additional innovations on the horizon.

Advised by Houlihan Lokey, the investment represents the latest in a series of strategic moves by Havas to accelerate its transformation through AI, data, and content. Together, Havas and Ostro will unlock new opportunities for life sciences companies to move beyond awareness—toward engagement that is adaptive, intelligent, and agentic.
