About Flexnode

Born in design and construction. Built for AI infrastructure.

Flexnode is the industrialized platform for AI factories. Every deployment brings the same four inputs: customer requirements, site conditions, available power and a chip platform. We resolve them against one standardized system into a data center that can be built, financed and run. Industrial fabrication partners build the power, cooling and structural assemblies in factories while the site is permitted and prepared, so the two schedules finish together. Every configuration we resolve is kept, and each new project starts from validated work. We build from 4.5 to 18 MW, sized for the metros and communities where inference capacity serves its users. Our team has engineered transit hubs and supertall towers, designed libraries and memorials, and delivered millions of square feet across ten countries. We are founded from and backed by the industry, and we build AI infrastructure the way that industry builds everything else that has to last.

Story Principles Timeline

Our story

Flexnode began with a construction firm’s question. Andrew Lindsey led applied R&D at Alpha Corporation, an engineering and construction management firm, on complex, secure building programs where repeatable subassemblies had to adapt to each location. Around 2019 he began asking where the data center market was heading, and saw demand for compute about to collide with a construction industry short of skilled trades and losing experience to retirement.

With co-founder Bob Mazer, he studied the companies that had tried modular data centers before. Many had shipped fixed containers, and two limits kept recurring: the units could not be configured to a site, and adapting them later often cost more than buying new ones.

The answer they pursued was a building system: bolt-together subassemblies, built in a factory to common rules, configured for each project and adaptable after it is built. By 2021 the work centered on liquid cooling for high-density compute and on facilities a host community could live alongside.

Engineering partners including Arup helped turn the concept into a design, and the team grew to include architects, structural engineers and builders with decades of delivery behind them. Today Flexnode configures, manufactures and delivers NX buildings from 4.5 to 18 MW, and develops and operates capacity of its own.

How it works

Four principles behind every NX building.

Each one is a design rule applied on every project, from the first configuration to the last commissioning test.

Distributed

Grid-attached sites near cities and workforce, sized to the power available.

Configurable

Customer requirements, site conditions, available power and the chip platform go in. A facility configured to them comes out, from one process, on standard specifications any qualified factory can build to.

Adaptable

The building is reconfigured, expanded and re-clad after it is built.

Upgradable

A building planned to take new rack densities and chip generations as they arrive.
