The operating system for renewable energy. An AI platform plus expert services that turns a chaos of project PDFs into a single source of truth - so solar and storage actually get built.
Somewhere right now a solar developer is staring at a folder. Inside it: four hundred documents, three versions of the same interconnection agreement, a tax memo nobody has read, and a deadline that moved last Tuesday. That folder is where clean energy projects go to stall. Euclid Power exists to make sure they don't.
Today Euclid is embedded in more than a thousand solar and storage projects across the United States. It does not own the power plants. It does something quieter and arguably more important - it runs the layer underneath them. Developers, investors, and asset owners use Euclid to pull every scattered file into one place, let an AI engine read it, and walk away with answers instead of anxiety.
The result reads like a magic trick that is really just good plumbing: diligence and transactions that once took months now take days, sometimes a single one.
"Our customers are navigating regulatory friction and market uncertainty every day to supply power that people desperately need. We help them move through that complexity faster."
- Jacob Sandry, Co-founder & CEOHere is the uncomfortable truth the industry rarely says out loud: the bottleneck for renewable energy is not always panels, or batteries, or even capital. Often it is information. A single utility-scale project can generate thousands of documents across development, financing, and construction. Each one hides a number that matters - a cost line, a deadline, a risk indicator - and each one is one email forward away from being lost.
When a deal needs to close, teams have historically done the only thing they could: read everything, by hand, again, under deadline. It is slow, expensive, and - in an industry where, as Sandry likes to point out, 99% accuracy isn't good enough - genuinely dangerous.
The grid cannot wait for someone to finish reading. Euclid's founders decided the reading should not be done by a person at all.
"99% accuracy isn't acceptable. In energy finance the last 1% is where the money - and the risk - lives."
- The Euclid thesis, on building AI for high-stakes diligencePlenty of software companies try to fix industries they have never worked in. Euclid did the opposite. It was founded in 2021 by three people who had spent their careers inside renewable energy and watched the document problem swallow good projects whole.
CEO Jacob Sandry started out at Generate Capital under clean-energy figure Jigar Shah, then moved to the investment team at Goldman Sachs' Renewable Power Group. That is where the a-ha moment landed - he left, taking a couple of Goldman teammates with him, to build the tool he had always wished existed. He was joined by Ryan Guay, now President and Head of Innovations, and Brian DeMaio, now COO and Head of Services.
Their bet was specific and a little contrarian: software alone would not be enough. Renewables are too messy, too high-stakes, too human. So Euclid wrapped its AI platform in actual expert services - engineering, construction, compliance, finance - run by people who have closed these deals before. Pure-software purists raised an eyebrow. Customers signed up.
"Started by renewable energy veterans who have developed, financed, and built projects themselves."
- Euclid Power, on why the founders knew where the bodies were buriedJacob Sandry, Ryan Guay, and Brian DeMaio leave the worlds of energy investment and development to build the operating system they wished they'd had.
Euclid embeds in 1,000+ solar and storage projects, onboards 12 GW of capacity, and supports more than $10B in renewable investment.
With participation from HSBC Asset Management, Spero Ventures, Toba Capital, Designer Fund, and Commonweal Ventures - fuel to meet surging energy demand and new compliance challenges.
Named one of Fast Company's Most Innovative Companies for 2026.
Launches a service that screens a renewable deal in roughly a day, as deal volume surges.
Buys Thresh to sharpen AI-powered diligence across its software and services suite.
Strip away the branding and Euclid does one deceptively simple thing: it reads. Its AI engine ingests the document pile, automatically tags each file, and extracts the data points that decide a project's fate - cost lines, deadlines, risk indicators - then collates them into one up-to-date view. The folder of dread becomes decision-ready intelligence.
On top of that core, Euclid ships tools tuned to the industry's real pain points.
The AI operating system. One source of truth that tags documents and surfaces the numbers that matter, automatically.
AI-driven due diligence that surfaces project risks fast, so a deal can be screened before it eats a quarter.
A full screening turnaround in roughly a day - built for an era where deal volume keeps climbing.
Tools and experts to stay ahead of shifting tax-equity and regulatory requirements.
Euclid reports clients cut transaction timelines by as much as 60%, with red-flag screening compressing to roughly a day. Figures are company-reported.
"A single source of truth for renewable energy teams - turning scattered documentation into actionable intelligence."
- How Euclid describes itself, and, annoyingly for competitors, how customers describe it tooEuclid's mission is four words long: build more, faster. Behind it sits a belief that the clean energy transition is not held back by ambition but by friction - and that friction is, mostly, solvable. Backers agree. The $20M Series A was led by Venrock, with HSBC Asset Management joining alongside existing investors Spero Ventures, Toba Capital, Designer Fund, and Commonweal Ventures.
Internally the company runs on six values - Excellence, Ownership, Belief in making a difference, Think big, Care, and Growth - which is a lot of values, though for a company asking customers to trust it with billion-dollar decisions, perhaps not too many.
Customers already include names like UBS, Ameresco, and Tritec Americas. The pitch to the next thousand is the same as the first: the energy people desperately need should not be delayed by a missing PDF.
Energy demand is climbing. Compliance rules keep shifting. Deal volume is surging, not slowing. Every one of those trends makes the document problem worse - and every one makes Euclid more useful. That is the bet inside the bet: the messier the energy transition gets, the more it needs a control room.
So return to that developer and that folder of four hundred documents. The deadline still moved last Tuesday. The tax memo nobody read still matters. But now the folder is not where the project stalls. It is where the project takes shape - because something already read everything, flagged the one line that would have killed the deal, and handed back an answer before lunch.
That is the whole company, really. Euclid did not make clean energy. It made clean energy easier to finish.
