GlacierGrid

"The walk-in freezer is, somehow, a climate front line. A small SF company is making sure it doesn't stay quiet about it."

The Profile

A company built behind the refrigerator door.

At 3:14 a.m. in a Domino's somewhere in Ohio, a refrigerator compressor decides it has had enough. It does not announce this. It simply begins drawing 18% more power than it did yesterday, while creeping two degrees warmer inside. The mozzarella does not know. The night manager does not know. Nobody knows - except, in this case, a small dashboard glowing on a laptop in San Francisco, where an alert has already pinged, a work order has already drafted itself, and the fridge has been politely rescheduled for a service visit before breakfast.

This is the unglamorous, unphotogenic, deeply consequential business of GlacierGrid. It is also, depending on who you ask, one of the more interesting climate companies in the country.

"Cooling is responsible for roughly 10% of global CO2 emissions. Almost no one is paying attention." That, in a sentence, is the GlacierGrid thesis.

GlacierGrid - which until February 2024 went by Therma - is an AI-powered platform for the part of commercial buildings nobody wants to think about: the HVAC, the walk-ins, the reach-ins, the ice machines, the rooftop units humming above every McDonald's, Marriott and 7-Eleven you have ever walked into. Founded in 2020 by Manik Suri and Aaron Cohen, the company sits in a category most people would call "boring," and which the rest of us increasingly call "the climate fight."

What it does

Sensors, software, and a hard look at the cold chain.

GlacierGrid's Cooling Intelligence Platform pairs LoRaWAN-enabled sensors with machine learning and equipment controls. The sensors stream temperature, humidity and occupancy data from every fridge, freezer and HVAC unit on a property. The software figures out what is normal, what is not, and what to do about it.

Product · Platform

Cooling Intelligence Platform

The brain. Centralized analytics, alerts, compliance logs and energy reporting across every site - whether you operate three locations or three thousand.

Product · Hardware

Wireless Sensors

Low-power, long-range LoRaWAN sensors for temperature, humidity and occupancy. Installed in minutes, batteries that last years.

Product · Controls

Smart HVAC & Refrigeration

Set-point management, smart scheduling, and demand response integration that turns flexible loads into real utility savings.

Product · Mobile

Mobile & Web Dashboard

Operators see one screen across one site or 3,000. Managers see proactive alerts before the steaks turn or the AC stops blowing.

By the numbers

Why anyone bothers.

GlacierGrid customers run the kinds of operations where small inefficiencies become big problems. A 1% drift in a freezer is invisible at one store. It is catastrophic across 14,000.

The math goes like this: a typical multi-site operator is leaking 15-25% of its cooling spend to old compressors, doors left open, set points nobody adjusts, and demand charges that pile up during peak hours. GlacierGrid's pitch is that software, applied carefully, claws most of that back - and the carbon along with it.

It is not glamorous. It is the kind of climate work that looks like a Tuesday afternoon spreadsheet. Which is, of course, what most climate work actually looks like.

Who uses it

A guest list nobody planned for.

For a category that lives behind a stainless steel door, GlacierGrid has assembled an unusually recognizable customer roster. Quick-service restaurants. Hotels. Convenience stores. Universities. Ski resorts. Airlines. Anywhere cooling is critical and the operating margin is thin.

The people

The unlikely team behind the cold chain.

The CEO came from policy. The COO came from energy algorithms. The product lead came from implementations. Each arrived at GlacierGrid via a different on-ramp, and stayed for roughly the same reason.

Manik Suri

Founder & CEO

Harvard AB, Cambridge M.Phil, Harvard JD. Previously co-founded GovLab at NYU and worked at the White House National Economic Council. The unusual-for-tech detail: a policy brain pointed squarely at industrial decarbonization.

Gerald Zingraf

Chief Operating Officer

13+ years in energy management. Three-time founder with multiple patents in energy algorithms. The engineer who knows where the watts actually go.

Liz Piontkowski

VP of Operations

A decade-plus spanning finance, HR, supply chain and customer experience - including time at Chick-fil-A. Operator's operator.

What you can do with it

Five things, plainly stated.

01 · Operator

Stop losing food.

Real-time alerts on temperature drift before product is unsellable. 60.5M pounds of food protected, per company reporting.

02 · Facilities

Schedule fewer trucks.

Predictive maintenance reduces unplanned service visits. Fewer truck rolls, fewer headaches.

03 · CFO

Trim demand charges.

Peak load shaping and utility demand response unlock savings that line items can actually see.

04 · ESG lead

Report what you actually saved.

Carbon and energy dashboards designed for sustainability reporting and compliance disclosure.

Closing scene

Back to the Domino's in Ohio.

By 7 a.m., a technician has replaced a fan motor. The compressor is back to its baseline draw. The night manager will arrive in two hours and never know any of this happened, which is precisely the point. The mozzarella is fine. The energy bill is a little smaller. A modest amount of carbon never enters the atmosphere.

Multiply that quietly-averted episode across thousands of locations, across the freezers of McDonald's and the rooftop units of Marriott and the dairy walk-ins of every gas-station coffee program in America, and you start to see why a small team in San Francisco bothered.

GlacierGrid is not selling a vision of the future. It is selling a more boring version of the present - one where a fridge that is about to fail does not get to. The climate dividend is the part that nobody puts on the box. It is, however, the reason the company exists at all.

Cooling is the climate story you forgot you were standing inside. GlacierGrid is the company quietly rewriting it, one walk-in at a time.
