Dan Caruso, Managing Director, Caruso Ventures; Founding CEO of Zayo Group

Dan Caruso built Zayo from a startup into an $8.5B bandwidth infrastructure platform through 45 acquisitions. In Part 1, he walks through the full buyer-led playbook — how the thesis was built on a contrarian bet that everyone else got wrong, how proprietary deals were sourced through early relationship-building, and why fast integration wasn't a reputation problem — it was a competitive advantage.

He also breaks down the metric trap most roll-up operators fall into: mistaking EBITDA growth for true value creation. If your board is tracking acquisitions individually or your deal structure is loaded with earnouts, this conversation will challenge how you're running the program.

What you'll learn:

How to identify and build a contrarian acquisition thesis with investor alignment
Why proprietary deal flow is a brand and relationship problem, not a sourcing problem
How Zayo executed an unsolicited, fully funded offer on a larger public company — and won
Why tracking individual acquisitions kills synergies in a roll-up
When earnouts hurt more than they help — and what to use instead
How clean, all-cash offers win on certainty, not price

Dan's approach to thesis validation, investor alignment, and platform value creation is documented in the Roll-Up Readiness Assessment inside the Intelligence Hub, a stage-gated guide built directly from this conversation.
