A lan Trefler is the founder and CEO of Pegasystems, a software company that specializes in business process management (BPM) and customer relationship management (CRM) solutions. A native of Boston, Trefler was a gifted student and a chess prodigy, co-champion of the 1975 World Open Chess Championship. This strategic mindset would later inform his approach to building his software empire. He founded Pegasystems in 1983 with a vision to create software that could automate complex business processes and adapt to changing rules without requiring traditional programming.

For decades, Trefler has led Pegasystems, growing it from a small startup into a major publicly traded enterprise software company. Its platform, known as Pega, is used by some of the world's largest corporations in finance, healthcare, and telecommunications to streamline their operations and improve customer engagement. Trefler is not only a technologist but also an author, having written the book "Build for Change," which outlines his philosophy on creating agile and future-proof business systems. He remains deeply involved in the company's strategy and product development, staying true to his original vision of making complex software more intelligent and accessible.
