Richard William Costolo was born on September 10, 1963, in Royal Oak, Michigan, a suburb of Detroit. Growing up in the Midwest during the 1960s and 1970s, Costolo developed an early interest in both technology and communication—interests that would later define his career trajectory.

• Degree: Bachelor of Arts (BA)
• Fields of Study: Computer Science and Communication
• Graduation Year: 1985

This combination of technical computer science training and communication studies would prove remarkably prescient, giving Costolo a foundation that bridged the gap between engineering and business—an uncommon combination in Silicon Valley at the time. The dual focus allowed him to understand both the technical aspects of product development and the critical importance of storytelling, messaging, and human connection in technology.

Early Career

Andersen Consulting / Accenture (1985-1990)

Key Influences and Development

Technical Foundation

Costolo’s computer science education gave him the technical literacy to engage with engineers and understand product development at a fundamental level. Unlike many executives who come purely from business backgrounds, Costolo could read code, understand system architectures, and participate meaningfully in technical discussions.

Communication Skills

His communication studies provided a differentiator that would serve him throughout his career. Costolo became known for his wit, storytelling ability, and public speaking skills—rare qualities in a technology executive.

The Liberal Arts Perspective

Costolo often credits his liberal arts education for shaping his approach to leadership and problem-solving. The interdisciplinary nature of his studies encouraged creative thinking and the ability to draw connections between seemingly unrelated domains—a skill that would prove invaluable in the rapidly evolving technology industry.

Transition to Entrepreneurship

After five years in the corporate consulting world, Costolo was ready to apply his unique skill set to the emerging world of web technology. The early 1990s marked the beginning of the commercial internet era, and Costolo recognized the opportunity to build something of his own.
