During his time at Michigan, he was also drawn to improvisational theater. He became deeply involved in performing comedy, developing his skills in public speaking, creative thinking, and leadership—qualities that would later prove valuable in his business career.

After graduation, he made an unexpected move by relocating to Chicago to pursue a career in improv comedy. He trained and performed at The Second City, one of the most prestigious comedy theaters in the country, known for producing legendary comedians like Tina Fey, Bill Murray, and Stephen Colbert.
Early Career in Technology
Although Costolo enjoyed his time in the world of improv, he eventually returned to his tech roots, beginning his professional career at Andersen Consulting (now Accenture).
He worked there for eight years, gaining experience in software development, consulting, and business strategy.
In the mid-1990s, during the early days of the internet boom, Costolo decided to venture into entrepreneurship. He launched Burning Door Networked Media, a tech company focused on web-based networked media solutions.
The company was later acquired by Digital Knowledge Assets in 1996, marking his first successful business exit.
Rise as a Tech Entrepreneur
SpyOnIt (1996 – 2000)
After selling Burning Door, Costolo co-founded SpyOnIt, a company specializing in web monitoring and alerts. SpyOnIt provided tools that could track website updates and send users notifications—a concept that was ahead of its time.
In 2000, SpyOnIt was successfully sold to another company, providing Costolo with more capital and experience to continue building new tech ventures.
FeedBurner (2003 – 2007)
In 2003, Costolo co-founded FeedBurner, an RSS feed management service. At the time, RSS feeds were a crucial part of how people consumed news, blogs, and other online content. FeedBurner allowed users to track, optimize, and monetize their RSS feeds, making it a valuable tool for publishers.
FeedBurner quickly grew into a major player in the tech industry, catching the attention of Google, which acquired FeedBurner in 2007 for an estimated $100 million.
After the acquisition, Costolo joined Google, working in various leadership roles within the company.
Joining Twitter: From COO to CEO
In 2009, Costolo left Google and was hired as the Chief Operating Officer (COO) of Twitter. At the time, Twitter was still a relatively new platform but was growing rapidly as a real-time social media and communication tool.
In 2010, Costolo was promoted to CEO of Twitter, replacing co-founder Evan Williams. Under his leadership, Twitter underwent massive expansion, significantly increasing its user base, advertising revenue, and cultural influence.
