Bandwidth: John Siegel, Partner at Columbia Capital

In this episode of The Bear Roars, Dan sits down with John Siegel—Partner at Columbia Capital and telecom dealmaker—for a candid conversation about collapse, conviction, and the fiber-fueled comeback of digital infrastructure.

John reflects on how Columbia navigated the “nuclear winter” following the dot-com and telecom crashes, why investing in ICG felt like career suicide at the time, and how that bold bet led to Columbia’s most successful infrastructure play.

They unpack how trust between investors and operators unlocked unprecedented value, the strategic chess match behind acquiring AboveNet, and the broader implications of Zayo’s massive rollout. John also shares stories from European deals like EU Networks and GTS Central Europe, and weighs in on how the AI-driven infrastructure boom feels eerily familiar to the fiber land rush of 20 years ago.
