Calgary's Innovation Strategy Faces Its Ultimate Test After Landmark Tech Deal

[CALGARY, AB] — A Calgary company just sold for US$4.75 billion. Let that number sit for a second.

CoolIT Systems Inc. — a local firm that makes liquid cooling technology for data centres — was acquired by Ecolab in what is officially the largest tech deal in Calgary's history. For context: less than three years ago, in June 2023, private equity giant KKR & Co. Inc. picked up CoolIT for US$270 million. Ecolab just paid nearly eighteen times that amount. That's not a valuation bump. That's a seismic reframe of what Calgary tech is worth on the global stage.

Why a Water Company Just Paid $4.75B for a Calgary Cooling Firm

If Ecolab sounds familiar but out of place here, that's because it is — and it isn't. The Minnesota-based company has deep roots in water, hygiene, and industrial services. But the AI boom has quietly turned data centre cooling into one of the most strategically critical problems on earth. Every server farm powering large language models and AI infrastructure runs hot. Dangerously hot. CoolIT's liquid cooling systems solve that problem at scale — and CoolIT is very, very good at it. The company is expected to generate approximately US$550 million in sales over the next 12 months. Ecolab wasn't buying a local darling. It was buying infrastructure for the AI era.

This Didn't Happen by Accident

The storyline of Calgary tech as a scrappy underdog is getting harder to sell. CBRE has recognized Calgary as North America's fastest-growing tech talent market for two consecutive years, spanning 2021 to 2024. In that same window, the city's tech workforce expanded by 61.1%, adding 24,500 jobs and pushing the total to 64,600 workers. The ecosystem injected $8.1 billion into the local economy between July 2021 and December 2023 alone.

Calgary Economic Development launched its city-wide Innovation Strategy in April 2025 — a 10-year roadmap targeting 187,000 new jobs and over $28 billion in economic activity by 2034. The Alberta Ministry of Technology and Innovation, stood up in October 2022, has been quietly building the provincial scaffolding around it. The CoolIT deal isn't just a win. It's proof of concept.

The Question Nobody Wants to Answer Out Loud

Here's the friction embedded in a story that reads like a pure win: when a city's crown jewel gets bought by a foreign multinational for nearly five billion US dollars, who actually benefits? Local founders and early investors who rode the valuation curve — absolutely. Calgary's reputation as a serious tech market — without question. But jobs, IP, and corporate decision-making power don't always stay put after an acquisition. Ecolab is headquartered in Saint Paul, Minnesota. CoolIT's Calgary office doesn't vanish overnight, but the long-term gravitational pull of a parent company rarely runs north.

The optimist's read — and Calgary Economic Development would certainly offer it — is that a deal this size signals to global capital that this city produces companies worth acquiring at world-class prices. That signal attracts founders, venture dollars, and the next generation of CoolITs.

The harder question is whether Calgary's innovation strategy is built to keep companies here, or just to grow them well enough that someone else wants to buy them.

CoolIT's founders and shareholders just had the best week of their professional lives. The city gets to celebrate a record. And somewhere in Saint Paul, an executive team is figuring out exactly what they're going to do with their very expensive, very Canadian cooling company — and how much of Calgary stays in the picture when they do.
