What Rosa & Co does
Rosa & Co. is an employee-owned, private drug development consultancy founded in 2002 by Ron Beaver, PhD and headquartered in San Carlos, California, with a second office in Boston. The firm specializes in quantitative systems pharmacology (QSP) through its proprietary PhysioPD (Physiological Performance Dynamics) Research methodology, which translates physiology, disease pathophysiology, and drug pharmacology into customized, interactive mathematical Research Platforms that simulate disease mechanisms, drug effects, and clinical outcomes. Supporting components include the Model Qualification Method (MQM), described as the only published peer-reviewed methodology for QSP model qualification, Virtual Patients for in silico clinical trial simulation, the PhysioMap graphical model architecture, and integration of AI/ML techniques (such as surrogate modeling for virtual patient generation and ML-based biomarker discovery). Commercially, the firm has extended into market modeling via the ForecastMD Platform and a two-week DueDiligenceMD pharma asset research service.
Rosa serves pharmaceutical and biotechnology R&D organizations globally, with reported repeat engagements with a majority of the Top 20 global pharmaceutical companies and long-term strategic research agreements with Sanofi and Chugai. The customer base spans metabolic diseases, oncology, CNS, immunology, dermatology, cardiovascular, and rare diseases, and includes named relationships with Pfizer, Bristol-Myers Squibb, Merck, Genentech, Boehringer Ingelheim, Takeda, Lundbeck, Servier, Otsuka, Grünenthal, Amgen, MedImmune, and others, plus consumer product work for Procter & Gamble.
Rosa generates revenue through professional services engagements, including project-based PhysioPD consulting and multi-year strategic research agreements; pricing is custom and not publicly disclosed, with no licensing fees attached to the proprietary methodology. The firm operates through direct enterprise sales, scientific thought leadership (a worldwide webinar series since 2011, ACoP/PAGE conference presence, ISoP leadership), and an extensive peer-reviewed publication record; strategic technology partnerships include MathWorks (MATLAB/SimBiology) and, as of October 2025, PhenoVista Biosciences to support New Approach Methodologies adoption under FDA Modernization Act 2.0.
