Prezent Vivo is a Life Sciences communications company headquartered in Los Altos, California. Founded in 2021, the company built an AI platform and expert services model to help BioPharma teams produce presentations, posters, and other communications faster and at lower cost than traditional medical communications agencies. The company combines a purpose-based AI agent, Astrid, with a team of medical writers, presentation engineers, and scientific directors. Prezent Vivo is used by Medical Affairs, Commercial, Clinical, and Market Access teams to produce brand-compliant, scientifically accurate data presentations, clinical posters, and other documents across the product lifecycle. Prezent offers three engagement models: a self-serve AI platform for internal, time-sensitive work; an overnight service in which teams submit a draft and receive a polished, brand-compliant deliverable by the next morning; and fixed-price projects, in which Prezent's experts deliver agency-quality work such as congress posters and MSL training decks on fixed timelines. Prezent reports that its platform is used by more than 150 Life Sciences companies, including 45 of the top 50 BioPharma organizations, and has supported more than 5 million deliverables since it began operating. Customers report time savings of 60 to 80 percent and cost reductions of 35 to 85 percent compared to traditional agency models. Prezent has raised more than $80 million in funding across six rounds, including a Series C round in October 2025 at a $400 million valuation. Investors include Greycroft, Nomura Strategic Ventures, and Multiplier Capital. Prezent acquired Prezentium in October 2025. Rajat Mishra serves as CEO.
