At TechCrunch Disrupt 2025, we are bringing three people who helped shape the modern internet to the Builders Stage. On October 28, Adam Bain, Dick Costolo, and David Fischer, now at 01 Advisors, will sit down for an exclusive fireside chat. They will discuss what it takes to build, scale, and fund startups in today’s ever-shifting landscape.
Before they were backing breakout companies like Tipalti and SpotOn, they were the operators behind some of tech’s most iconic companies. David Fischer is the former Chief Revenue Officer at Meta, where he scaled annual revenue from less than one billion dollars to over one hundred billion dollars, connecting two hundred million businesses with customers worldwide. Earlier, he built Google’s early sales engine.
Adam Bain is the former Chief Operating Officer of Twitter. He built its sales, product, and ad operations from scratch, growing revenue from millions to billions in just five years. Dick Costolo is the former Chief Executive Officer of Twitter. He scaled the company’s headcount by four hundred percent and boosted annual revenue from twenty-eight million dollars to two point two five billion dollars. Earlier, he founded FeedBurner, which was acquired by Google.
This conversation is not just about what they have done. It is about where they believe tech is headed next. Expect insights on finding product-market fit, scaling with intention, fundraising in today’s market, and what they look for when backing founders through 01A.
