The conventional image of a tech billionaire often involves yachts, private jets, and extravagant lifestyles. Brian O’Kelley, co-founder of AppNexus , challenges this notion entirely. After selling his company to AT&T in 2018 for $1.6 billion, he chose to keep less than $100 million for himself and donated the rest to charitable causes he and his family care about. His journey demonstrates that true success is not measured by wealth alone but by the meaningful impact one creates in society. For students, O’Kelley’s story offers lessons that extend far beyond entrepreneurship, teaching leadership, purpose-driven thinking, and resilience.
By tracing O’Kelley’s trajectory, from his formative years at Princeton to the rise of AppNexus and his later ventures like Waybridge and Scope3, it becomes clear that ambition, values, and vision can coexist to build both personal success and societal good. Here’s what students can learn from his journey:
Success is measured by impact , not wealth
O’Kelley’s decision to donate the majority of his earnings highlights that financial gain is only one aspect of achievement. Students can learn that ambition should be guided by the desire to create meaningful change, and that true success lies in leaving a positive mark on society.
Build a strong academic and technical foundation
At Princeton University, O’Kelley earned a BSE in Computer Science, developing both technical expertise and critical thinking skills. Students can understand that strong academic training provides the tools to tackle complex challenges and lays the groundwork for long-term professional growth.
Develop holistic skills through extracurricular activities
Balancing studies with junior varsity basketball taught O’Kelley discipline, teamwork, and resilience. Students can learn that engagement outside the classroom nurtures character, enhances leadership skills, and prepares them for real-world challenges.
Lead through values , not authority
At AppNexus, O’Kelley emphasized a culture of inclusion, empowerment, and continuous learning. Students can learn that effective leadership is not about hierarchy, but about inspiring and enabling others to thrive while fostering innovation and collaboration.
Align career goals with purpose
O’Kelley’s ventures after AppNexus, including Waybridge and Scope3, focus on sustainability and ethical business practices. Students can see the importance of merging professional skills with meaningful causes, demonstrating that purposeful work drives both innovation and societal impact.
Cultivate vision and resilience
Transforming AppNexus from a small apartment startup into a global ad-tech leader required foresight, strategic thinking, and resilience. Students can learn that ambitious goals paired with perseverance and calculated risk-taking are essential for turning ideas into transformative ventures.
