The Startup That Saves Energy by Turning Things Off

Somewhere, an office is asleep. The electricity isn't.

It is 2 a.m. in an empty office park, and everything is technically off. The monitors are dark. The coffee machine is cold. The printer hasn't printed since Thursday. And yet the meter is spinning - quietly, patiently, billing someone for the privilege of powering machines that are doing absolutely nothing. This is phantom power, the electric grid's junk drawer, and it accounts for roughly a tenth of the average electricity bill. Most companies never see it. Revert Technologies built a business out of seeing it, and then switching it off.

The pitch is almost insultingly simple. You plug your equipment into a Revert device. The device talks to a cloud platform. The platform learns when things are actually used, watches what the utility is charging by the hour, and quietly cuts power to the stuff idling in the dark. No electrician. No rewiring. No new habits to learn. In an industry addicted to moonshots - fusion, gigafactories, continent-spanning transmission lines - Revert made a contrarian wager: that the fastest carbon savings come not from generating cleaner power, but from wasting less of the power we already have.

A pivot that started with lawnmowers

Revert's founders, Ryan Li and Joseph Lybik, did not set out to build a smart plug. They met at Yale - Li at the School of Management, Lybik in Yale College - and their first idea was stranger and heavier: energy-storage devices built from the batteries of electric lawnmowers, aimed at professional landscapers. To research it, they literally followed Yale's grounds crew around campus, clipboard in hand. The landscaping business didn't pan out. But the founders came away with a conviction that stuck: enormous amounts of energy are wasted in plain sight, and nobody is paid to notice.

Li knew the energy world from the inside. Before Yale, he'd spent years at Shell, watching how the industry thought about supply, demand, and price. Lybik brought the engineering. Together they reframed the problem. Instead of storing energy, what if you simply stopped spending it on things nobody was using? Standby power in the United States wastes an estimated 25 gigawatts and 44 million metric tons of carbon dioxide every year - the emissions equivalent of a small country's bad habits. That, they decided, was the business.

From a cube on Kickstarter to a platform for buildings

The first product had a name as warm as its mission was cold-eyed: the Teak Smart Cube, a patented multi-outlet smart surge protector that looked like it belonged on a designer's desk and behaved like an accountant behind the scenes. It managed which devices got power and when, killing standby draw while protecting equipment from surges. Revert launched it on Kickstarter in the winter of 2022, with roughly 500 people already on a waitlist. It was, in the founders' words, an attempt at "an AI-enabled solution that could save energy, emissions, and look sleek in a home."

Homes, though, were only the on-ramp. The real money - and the real waste - lives in commercial buildings, where thousands of devices hum through nights and weekends unattended. In 2023 Revert introduced the Acorn Smart Plug, a single-outlet unit aimed squarely at businesses. By 2024 the company had folded both products into one brand and one idea: plug-load management as a service. Hardware you can install yourself, software that does the thinking, and a report at the end that tells a facilities manager exactly how much energy, money, and carbon got saved by doing nothing.

Maine-made, and proud of the accent

There's a quiet regionalism to Revert. The company runs out of Brunswick Landing in Maine, assembles and distributes locally, and manufactures through a partner - Alternative Manufacturing, Inc. - based up the road in Winthrop. The product names sound like a New England forest: Teak, Acorn. It's climate optimism with a woodsy accent, and it's more than branding. Building hardware in the United States, near the team, gives a small company control over quality and iteration speed that offshoring can't match. It also gave Revert a home-state champion.

That champion was the Maine Venture Fund, which invested alongside the Roux Institute Techstars Accelerator - the Northeastern University-affiliated program in Portland that helped Revert sharpen its commercial edge. The company has raised about $1.1 million to date. It is not a war chest. It's a runway, deliberately lean, for a team that describes itself as "small and mighty" - a dozen-odd technology lovers and, in their own phrase, climate optimists, led by Li as CEO and Lybik as CTO, with operations run by a compact crew rather than an army.

Why subtraction is a hard sell, and a good one

Selling "less" is difficult. People understand adding solar panels; they can point at them. Nobody throws a ribbon-cutting for a printer that switched itself off at midnight. Revert's challenge has never been the technology - it's making invisible savings visible enough to feel real. That's why the platform leans so hard on reporting: real-time analytics, utility-price intelligence, carbon accounting straight from the outlet. The device does the switching; the dashboard does the convincing. Support for Wi-Fi and LoRaWAN means it can reach the far corners of a warehouse or campus where Wi-Fi gives up.

The competitive field is real - energy-monitoring players and smart-plug makers all circle the same outlets. Revert's bet is that most of them stop at measurement. Knowing you waste power is a diet app that only weighs you. Revert's whole point is the second step: automatically doing something about it, at the level of the individual plug, without asking a human to remember. It's demand response for the rest of us, packaged small enough to fit in a hand.

What you can actually do with it

Strip away the mission language and Revert is a practical tool with an unusually short list of chores. A facilities manager plugs the Acorn into the outlets feeding vending machines, monitors, task lighting, or lab equipment - the quiet always-on offenders - and lets the platform build a schedule around real occupancy. Weekend shutdowns happen without a memo. Devices power down when grid electricity is at its dirtiest and priciest, then wake before anyone arrives. When a utility runs a demand-response event, the platform can lean into it, trimming load at the moment the grid is straining. And because every switch is logged, sustainability teams get carbon numbers they can put in a report instead of estimates they have to defend.

For a business, the appeal is that none of this requires a capital project. There's no panel to open, no contractor to schedule, no downtime to justify to a nervous operations lead. You buy plugs, you plug things in, and the savings accrue in the background - the kind of retrofit that pays for itself and then keeps paying. That's a deliberate design choice. Revert understood early that the enemy of energy efficiency isn't cost so much as friction: the effort, the disruption, the meeting no one wants to schedule. By shrinking the intervention to something the size of an outlet, it removed the excuse.

Back to that 2 a.m. office

Return to the empty office park at 2 a.m. The monitors are still dark, the coffee cold, the printer still idle since Thursday. But now the meter isn't spinning. The equipment that used to sip power all night has been switched off at the plug, on a schedule the building never had to think about, at exactly the hours the utility charges most. Nobody stayed late to do it. Nobody will notice in the morning - except the person who reads the bill, and the dashboard that tallies up the carbon that never got burned.

That's the whole trick, and it's why Revert Technologies is more interesting than its modest size suggests. It didn't invent a new source of energy. It noticed the energy we throw away, made it visible, and then did the unglamorous work of turning it off. In a field that loves the future tense, Revert is stubbornly present tense: plug in today, waste less tonight. The office sleeps. Now, finally, the electricity gets to sleep too.
