run buildings.

Exergio is the AI performance layer for buildings — born inside one of Europe's largest property and engineering groups, supervised by a dedicated engineer for every site, and paid for by the savings we guarantee.

Our roots

A spin-off from the people who already run the buildings.

Exergio isn't a startup that decided buildings looked interesting.
We were the engineering team inside the group that has operated, maintained and metered buildings across Europe for more than three decades.

We grew up inside the ICOR group — a corporate group of 100+ companies founded in 1990, operating across public utilities, energy, real-estate development, smart metering and facilities management. Sister companies like City Service (Europe-wide facilities management), Axioma Metering (ultrasonic heat and water meters in 55+ countries), and Mano Būstas (the digital property platform for residents) gave us a daily, ground-truth view of where buildings actually leak energy, comfort and money.
For years, our team was the one called when a BMS misbehaved, a chiller hunted, or an energy bill spiked. We saw the same patterns repeat across hundreds of buildings, vendors and asset classes — and we saw how much performance was being left on the table by systems that could only react, never anticipate.
So we built the platform we always wanted as engineers: an AI layer on top of any BMS that learns the building, supervises it 24/7, and is itself supervised by a real engineer. In 2021 it became its own company — Exergio — and was spun out of ICOR to scale beyond our sister companies' portfolios. Today, Exergio runs 367 buildings and 4.2 million m² across 16 markets.

We didn't write a thesis about buildings.
We worked in them for 30 years, then built the software we wished we'd had.

Our convictions

Three convictions that shape every line of code we ship.

If you remember three things about Exergio, make it these.
They answer the three biggest questions every building owner asks before buying AI: Is it safe? Does it serve my role? Will I actually save money?

01 · Supervised AI

Every building gets a Dedicated Building Engineer.

AI is not a black box at Exergio. Every property under our management is assigned a named, best-in-class engineer who watches the system 24/7, validates every algorithmic change, catches drift before clients do, and is the human voice on the other end of the line when something matters.
You don't buy software from us. You buy a managed performance partner — software plus an engineer, accountable to your numbers.

Software + engineer, always

02 · Full value chain

One platform for everyone responsible for the building.

Most building software picks a side: an owner dashboard, or a facility manager work-order app, or an asset-manager ESG report. Exergio is built for all three at once. Portfolio owners get a real-time performance view. Asset managers get shared live data and automated reporting. Facility managers get predictive alerts, fewer truck rolls, and tasks that don't get lost between organisations.

The whole real-estate value chain working from the same source of truth — and finally working in unison.

One platform, every role

03 · Guaranteed Savings

We don't promise savings. We guarantee them.

Our flagship commercial model is the Guaranteed Savings Model: the fee is contractually tied to a minimum kWh and € savings floor. If we miss the floor, the fee recalculates downward by a pre-agreed, symmetric formula. No "expected savings". No "potential". Contracted outcomes, verified against the utility meter.

Exergio is the real-time performance layer that replaces and upgrades traditional EPC — continuous optimisation in place of one- off retrofits, with 96% of our projects meeting or beating the guarantee.

Contracted outcomes, verified at the meter

Mission & vision

Why we get up in the morning.

A clear mission keeps us focused. A clear vision keeps us ambitious.
Both are written down so the team — and the buildings we work with — know exactly what we're here to do.

Mission

On a mission to stop energy waste in buildings.

Buildings account for ~40% of global energy use and a third of CO₂ emissions — and roughly a quarter of that is plain waste. Our daily work is to find that waste in every building we touch, and stop it.

No CAPEX excuses, no retrofit cycles, no waiting for the next renovation.

Vision

Buildings that think for themselves — supervised by humans.

Every asset, regardless of age, vendor or class, running at peak performance and continuously improving. Operated by AI, supervised by engineers, owned by people who finally have a real-time view of how their building is performing.

That's the world we're building toward.

The team

~20 people.
One platform. Hundreds of buildings.

Building engineers, data scientists, software engineers, customer success — and the Dedicated Building Engineers who supervise the AI across every site. Small enough to ship fast. Senior enough that you'll always speak to someone who actually knows your building.
