Built on Experience. Engineered for Change.

Our team has developed mission-critical facilities through multiple waves of technological evolution—from early enterprise hosting to today’s AI-driven architectures. This isn’t a pivot. It’s the next step in a platform that’s always been about enabling what comes next.

Infrastructure That Moves With the Market.

We believe tomorrow’s data centers won’t be built around generic models—they’ll be shaped by use, not speculation. Our vision is to serve the evolving needs of digital infrastructure by staying nimble, grounded, and responsive. From inference models to urban densification, we’re designing for what’s actually needed—in the core, at the campus, and everywhere in between.

Leadership

Operators. Technologists. Builders.

Legacy is built by technologists, infrastructure experts, and repeat entrepreneurs.

Our leadership team has built data infrastructure for some of the world’s largest tech platforms and fastest-growing AI innovators. We’ve scaled cloud environments, delivered power in complex markets, and rethought how infrastructure should respond to new workloads. This isn’t our first cycle. It’s where we do our best work.
