Marine Queniart Stojanovic Joins Prezent to Accelerate Life Sciences Growth

Palo Alto, CA, January 12, 2026 – Prezent announced today that Marine Queniart Stojanovic has joined the company as a Senior Executive Board Member. Marine joins industry stalwarts like Maria Martinez (ex-COO Cisco and Board Member, McKesson & Bank of America) and Charlotte Owens (SVP Medical Affairs, Genentech) on Prezent’s Senior Executive Board.

Marine has spent over 25 years in global leadership roles at GSK and Sanofi, serving in positions across commercial operations, general management, multi-country leadership, and digital transformation. Throughout her career, she has led global, local, and regional teams across the US, Europe, and South East Asia.

Marine’s appointment marks a significant milestone in Prezent’s mission to become the complete Business Communications AI platform for the Healthcare and Pharma industries.

As Senior Executive Board Member at Prezent, Marine will support the company’s global expansion into healthcare and life sciences, bringing her deep understanding of the industry, decades of experience navigating complex regulatory environments, and her impressive track record of driving enterprise transformation. Marine’s experience will help Prezent strengthen the company’s AI strategy, healthcare product capabilities, and enterprise partnerships.

"Marine’s leadership and global insight will be invaluable as we take Prezent into its next phase of growth and advance our vision of becoming an all-in-one Business Communications AI tool for the Healthcare and Pharma industries,” said Rajat Mishra, CEO and Co-Founder of Prezent AI.

“Life Sciences use-cases require deep industry and functional expertise. With Marine’s guidance, we will transform the business communication work-flows in Life Sciences, improving employee productivity and streamlining agency spends.”

Marine has led several high-impact transformation initiatives, including reinventing global commercial and medical engagement models, advancing digital and data-driven innovation, and accelerating organizational agility. 

“Healthcare and Pharma teams spend enormous time creating accurate presentations, especially in medical affairs, and this work often pulls them away from what really matters. Prezent solves a key pain point by turning complex data into compelling narratives quickly, while adding human expertise where it creates the most value. The result: clarity, impact and better decision making." said Marine Queniart Stojanovic.

‍"Communication is at the centre of every successful transformation, and Rajat and the team have a compelling vision for how life sciences companies can communicate more effectively. So I'm excited to support Prezent in shaping the future of leadership communication in healthcare."

Marine joins Prezent’s Senior Executive Board as Prezent expands its enterprise AI platform to address the complex communication needs of pharma and life sciences companies. Prezent had also recently launched Prezent API which enables pharma companies to automatically generate on-brand presentations for clinical updates, pipeline reviews, regulatory briefings, medical affairs, and executive communications directly from internal systems.
