G eorge Christ is an American billionaire who co-founded Altair Engineering, a global technology company providing software and cloud solutions for product development, high-performance computing, and data analytics. He established the company in 1985 alongside James Scapa and Mark Kistner in Troy, Michigan. While Scapa served as CEO, Christ played a significant role in the company's early growth and technological foundation.

Christ retired from Altair before its initial public offering in 2017 but retained a substantial equity stake. His wealth surged as the company grew into a major player in the simulation software market, serving industries ranging from automotive to aerospace. In a major exit event, Siemens agreed to acquire Altair for approximately $10.6 billion in late 2024/early 2025, a deal that further solidified the value of his long-held investment in the firm.
