Alexander Taubman, co-founder of Long Lake, is buying American Express Global Business Travel for $6.3 billion. The company is 111 years old. He just started Long Lake three years ago.

The Thesis: AI Deployment, Not AI Software

Long Lake was formed with the mission of "bringing AI into the real economy." Taubman observed that while frontier intelligence was advancing at a breathtaking pace—models that couldn't do addition four years ago now solve some of the ten hardest math problems—the real economy wasn't changing. The bottleneck, he argues, is not the technology. It is diffusion. Legacy systems, messy data, and human workflows make deployment genuinely hard. "The technology changes way faster than human nature does," he says.

The goal is not to sell software but to drive outcomes—faster growth, better customer experience, and higher margins.

Alexander Taubman is the co-founder and CEO of Long Lake, a company that buys established service businesses and uses AI to improve how they operate. He explains Long Lake’s $6.3 billion deal for American Express Global Business Travel, why deploying AI in the real economy is difficult and why he sees productivity gains creating more jobs as businesses grow. Alex describes how Nexus, Long Lake’s AI platform, connects models to business data and workflows, why its engineers work alongside employees in the field and why he wants to own businesses rather than sell software. He shares how his grandfather’s idea of “threshold resistance” applies to AI adoption, what he learned at Goldman Sachs and Oaktree and how investing in founder-owned businesses through Taubman Capital prepared him to build Long Lake. Alex also discusses the influence of Danaher, Henry Singleton and John Malone, why he values partners who make him more ambitious and why Long Lake plans to hold its businesses for decades. Including Amex GBT, he expects more than $4 billion in combined revenue the following year and explains why he believes long-term compounding could eventually build a trillion-dollar company.
