Our Founders
Andrew Siprelle
Andrew is driven by a passion to unlock the value of simulation and modeling in helping to solve real-world problems. Since founding Simulation Dynamics, Inc. (SDI) in the early 90’s, he has been an educator, a consultant, a simulation tool developer, and a smart applications technology leader.
Andrew coined the term “Discrete Rate Simulation”, and developed one of the earliest libraries for quickly building models of multi-stage plants that produce powder or bulk solids; e.g., a breakfast cereal plant.
ChiAha is the culmination of a lifelong dream for Andrew, who has always wanted to reinvent and more widely distribute the benefits of the DRS worldview.
