EVORA Put a Climate Accountant Inside the Building
Its first software supplier folded before the contract ink dried. EVORA answered by spending millions on SIERA, buying the pipes that feed it, and turning sustainability paperwork into an investment tool.
ESG Book Wants to Turn the Sustainability Questionnaire Into a Shared Ledger
The old ESG market sold answers in black boxes. ESG Book is betting that banks and companies would rather see the workings - and fill out the form only once.
Scope3 Found the Waste in Your Ad Budget. Now It Wants AI Agents to Spend It.
The ad-tech veterans behind Scope3 built a carbon meter for the internet's advertising pipes. Four years and $45 million later, they are turning that map into an AI marketplace - with real budgets, open standards and a hard question about who gets to make the buy.
The 46-Year-Old Software Company Teaching Utility Bills to Talk
EnergyCAP began with an engineer who could spot waste but could not get clean data. Four decades, one Enron detour and billions of meter readings later, it is turning the least glamorous document in business into a control panel for cost and carbon.
Novata Wants to Turn Private-Market Sustainability Data Into Something Investors Can Actually Use
Private companies were asked to prove their climate and social claims with tools built for accounting by email. Novata’s bet is that one shared data layer - backed by benchmarks, carbon math and human advisers - can turn that annual scramble into useful business intelligence.

Tim Howard Is Teaching Buildings to Tell the Truth
After three decades in software, the Clemson facilities operator turned a basement experiment into CarbonCents - a company that makes power, water and occupancy data useful before the next utility bill arrives.
CarbonCents Is Betting Facilities Chiefs Want Lower Bills Before Loftier Carbon Promises
The Clemson-born startup found a practical way into the climate-software market: make scattered building data useful to the people paying the utility bills. Now it is testing whether one dashboard can stretch from boiler rooms to boardrooms.
The 30-Hour Spreadsheet That Built a Climate Startup
Trucking is the biggest carbon line item in almost every supply chain - and until recently, most carriers reported it by hand. Celine King built software to do it in seconds, and sold it to an industry that hates change.
The New York Fund That Bet on Robots Before the Robots Could Walk
Parkway keeps a short list of bets and a long memory of building companies. That combination led a New York firm of about 15 people to the front of the humanoid-robot and quantum-computing races.
Sphera
Sphera sells the software behind decisions most people never see: whether a factory job is safe, a chemical is compliant, a supplier is fragile, or a product's carbon claim can survive an audit. Its bet is that those answers become more useful when they live in one system.
Alexis Normand
Alexis Normand spent years turning personal data into useful signals. At Greenly, he is applying the same instinct to corporate carbon - making an invisible liability legible enough to manage.
