Building a Binational Fiber Alliance: Lessons from a First-of-Its-Kind Deal
Hyperscalers don’t wait. When Microsoft, Google, or Amazon decides a market is strategic, they move — and they expect the infrastructure to be ready when they arrive. The US-Mexico corridor became one of those markets faster than most carriers anticipated.
The nearshoring boom accelerated it. AI infrastructure demand accelerated it further. And suddenly, a border that the fiber industry had treated as a handoff problem became the center of some of the most significant capacity conversations in North America.
I had a front-row seat to that shift — and eventually, I built something to respond to it.
The Gap the Hyperscalers Exposed
Hyperscalers and Tier 1 carriers share one trait: they think in ecosystems, not point-to-point transactions. When a hyperscaler is planning a cross-border deployment, they’re not looking for a fiber vendor. They’re looking for a partner who can own the outcome end-to-end — across geographies, across networks, across regulatory environments.
What they kept finding instead was fragmentation. A carrier with strong US infrastructure but limited Mexico reach. A Mexican operator with dense metro coverage but no US backbone. A handoff arrangement at the border that nobody fully owned and everybody quietly hoped wouldn’t break.
For hyperscalers, that’s a disqualifier. They’ll find someone else, or they’ll build it themselves. Neither outcome is good for the carrier ecosystem.
What It Took to Build It
I led the development of a multi-carrier fiber alliance spanning the US-Mexico corridor — designed specifically to serve the scale and reliability demands of hyperscaler and carrier-grade customers.
The concept was straightforward. The execution was not.
Aligning carriers across two countries means reconciling different commercial structures, different network architectures, different regulatory frameworks, and — most critically — different competitive instincts. Carriers that compete in some segments have to find a framework where cooperation in others actually makes business sense for everyone at the table.
That framework doesn’t exist off the shelf. You build it through relationships, through commercial creativity, and through a clear-eyed commitment to what the customer at the end of the chain actually needs.
The result: a program that produced over $80M in contracted revenue and gave hyperscaler and carrier customers something they hadn’t been able to find before — a single, accountable solution across the entire US-Mexico corridor.
What Hyperscalers and Carriers Actually Need
Hyperscalers buy certainty. Speed of deployment matters. Redundancy matters. But what closes the deal is confidence that when something goes wrong at 2am in a data center in Querétaro, someone owns it — not three carriers pointing at each other across a border. Any alliance structure that doesn’t solve the accountability question first will lose hyperscaler business.
Carrier customers buy reach they don’t have to build. A regional carrier trying to serve a multinational enterprise doesn’t want to manage a patchwork of bilateral agreements. They want a trusted partner with coverage that extends their own — cleanly, commercially, without margin erosion. That’s a different sales conversation than selling capacity. It’s selling leverage.
Both buyer types reward relationships over transactions. The carriers and hyperscalers that gave us the largest deals weren’t won through RFP processes. They were won through years of showing up as a strategic partner, not a vendor. That kind of trust is slow to build and almost impossible for a competitor to replicate quickly.
The Window Is Open — But Not Forever
The US-Mexico corridor is at an inflection point. Hyperscaler investment in Mexican data center capacity is accelerating. Nearshoring is restructuring manufacturing supply chains in ways that create massive new enterprise connectivity demand. And the carriers positioned to serve that demand — cleanly, at scale, across the border — will capture a disproportionate share of the next decade’s growth.
The infrastructure opportunity is real. The customer appetite is real. What’s still being figured out is the collaborative commercial model that lets carriers capture it together rather than losing it individually to the players who already figured it out.
I built one version of that model. The lessons from it are ones I carry into every strategic conversation I have today.
