Certara, Inc.
A maker of biosimulation software that lets drug developers test medicines in virtual patients before real trials, Certara's tools include Simcyp, Phoenix, and Chemaxon, and are used by researchers and regulators around the world. It was formed in 2008 from the merger of Tripos and Pharsight, two pioneers in molecular modeling and clinical trial simulation. The coined name "Certara" echoes the word certainty — a nod to its aim of making drug development more predictable.
