About Kurtz George
George Kurtz is the Chief Executive Officer and founder of CrowdStrike, one of the best-known U.S. cybersecurity companies listed on the NYSE/NASDAQ ecosystem. Company biographies state that he has led CrowdStrike since its founding in 2011 and brings more than 30 years of experience in security, revenue growth, and scaling organizations globally. Before CrowdStrike, Kurtz founded Foundstone in 1999 and served as its CEO until the company was acquired by McAfee in 2004. After that acquisition, he moved into senior leadership roles at McAfee, including Worldwide Chief Technology Officer, General Manager, and Executive Vice President of Enterprise. CrowdStrike’s official materials also note that he built his early entrepreneurial track record by recruiting the original Foundstone team and helping bring security technologies into broader enterprise use. At CrowdStrike, Kurtz is most closely associated with the company’s rise as a leader in endpoint protection, threat intelligence, and next-generation security services. His profile emphasizes his ability to commercialize emerging technologies, grow revenue, and build global operations. Over time, he has become one of the sector’s more visible executives, particularly on issues related to cybersecurity policy and software supply-chain risk. In 2021, he testified before the U.S. Senate Select Committee on Intelligence on cybersecurity and supply-chain threats, underscoring his standing as both a corporate leader and a policy-informed industry voice. Kurtz’s career reflects a long-running focus on cybersecurity entrepreneurship, product strategy, and business execution. He is widely presented as a founder-operator who has moved from building security products to scaling a public company with international reach. Recent company disclosures continue to identify him as CEO, founder, and a director of CrowdStrike. In public remarks and corporate positioning, he has consistently supported security models centered on visibility, automation, and rapid response to advanced threats. That combination of technical credibility and executive leadership has made him a defining figure in CrowdStrike’s evolution and in the broader cybersecurity market.
