TechCrunch Disrupt 2025 is coming to Moscone West in San Francisco, October 27–29, and we’re bringing the heavy hitters to the Builders Stage. On October 28, three names that helped shape the modern internet are sitting down for an exclusive fireside chat on what it takes to build, scale, and fund startups in today’s ever-shifting tech landscape.
Adam Bain, Dick Costolo, and David Fischer are now leading the charge at 01 Advisors, a venture firm investing in breakout companies like Tipalti and SpotOn. But before they were backing the next generation, they were the operators running some of tech’s most iconic companies.
Adam Bain, former COO of Twitter, helped transform the platform from a scrappy social tool into a global business. He built Twitter’s sales, product, and ad operations teams from the ground up, growing revenue from millions to billions in just five years.
Dick Costolo, Twitter’s former CEO, led the company through hypergrowth — expanding headcount by more than 400 percent, establishing its long-term strategy, and increasing annual revenue from $28 million to $2.25 billion. Before that, he founded FeedBurner, one of the earliest content distribution platforms, later acquired by Google.
David Fischer, former Chief Revenue Officer at Meta, was the architect of the company’s global ad business. Over more than a decade, he scaled annual revenue from under $1 billion to over $100 billion and helped more than 200 million businesses connect with customers across the globe. He also helped build Google’s early sales engine and once served in the U.S. Treasury Department.
