Somewhere in Maine, a stand of spruce and fir is getting older on purpose. A landowner who might have cut it this year is letting it stand instead - and a company in Austin, 2,000 miles away, is watching from space to make sure that decision is real. No clipboards. No handshake promises. Just LiDAR pulses, satellite passes, and a machine-learning model that counts carbon the way an auditor counts cash. This is Renoster in 2026: a company that spent years telling the carbon market it wasn't good enough, and then decided to do something about it.
The market ran on trust. Renoster ran the numbers.
The voluntary carbon market has a peculiar problem: you cannot see what you are buying. A credit is a promise that somewhere, a ton of carbon that would have entered the atmosphere didn't - because a forest was saved, a peat bog protected, a mangrove left standing. For years the industry asked buyers to take that promise largely on faith, backed by paperwork the buyer could rarely check.
Renoster's founders found that unacceptable. Founded in 2019 by Saif Bhatti and Elias Ayrey - the latter a forester with a PhD in reading trees from orbit - the company set out to do the thing the market avoided: independently verify whether the trees were actually doing what the paperwork claimed.
Their tools were unusual for a ratings shop. Instead of interviews and desk reviews, Renoster leaned on remote sensing - LiDAR, satellite imagery, and AI - to assess and forecast the quality of nature-based projects. The company specialised in forestry, mangroves, and peat, and it did its grading in public.
The results were sobering. Through its flagship product, the Mercury rubric, Renoster reviewed more than 200 projects and over 500 million credits. In its first year alone it rated 170 forestry projects, roughly 400 million nature-based credits. And project after project, the data told the same uncomfortable story: a lot of what the market was selling did not hold up.

A skeptic and a scientist
Saif Bhatti
The operator who refused to accept "trust us" as a business model. Bhatti has been Renoster's public voice - on The Pitch podcast, at the Climate Collective, and across the carbon-market debate - arguing that transparency isn't a feature, it's the whole point.
Elias Ayrey, PhD
A remote-sensing specialist with a PhD and MS in Forest Resources from the University of Maine. Ayrey combines satellite imagery, LiDAR, and AI to review and rate the world's forest carbon projects - reading forests from space so buyers don't have to take anyone's word for it.
What half a billion credits taught them
From critic to builder
Here is where most companies would have kept collecting fees. Ratings are a comfortable business: you grade, you invoice, you never have to guarantee the outcome. Renoster chose the harder road. If the credits weren't good enough, the logic went, someone had to make better ones.
So in 2025 the company did something rare - it retired its own flagship. Renoster announced that the Mercury platform's ratings represented its opinion as of July 2025 and would not be maintained further. No spin, no optimistic footnote. Just an honest expiration date on an honest product.
In its place came Apollo, an improved forest management program - and a full pivot from grading the market to supplying it. The idea is almost stubbornly simple. Small landowners in Maine, who might otherwise harvest on short rotations, are paid to wait: to let their forests grow longer, store more carbon, and turn that patience into high-integrity credits.
The engineering underneath is anything but simple. Each Apollo property carries a verified harvest history and documented intent, so that credits represent a real change in practice rather than business as usual. Renoster's stack of AI, LiDAR, and satellite data monitors the forest continuously, and the program is backed by Isometric's IFM Protocol with insurance from Kita. The pitch to landowners: 25 acres minimum, zero upfront cost.

The toolkit
Apollo
An improved forest management program with small Maine landowners. Longer rotations, more stored carbon, verified via LiDAR - backed by Isometric's protocol and Kita insurance. 25 acres, zero upfront cost.
Mercury
The public carbon-ratings platform that reviewed 200+ projects and 500M+ credits across forestry, mangroves, and peat. Frozen as Renoster's July 2025 opinion as the company moved to supply.
Project Explorer
A public interface for exploring and comparing carbon-project quality - extending the transparency mission beyond paying clients to anyone curious enough to look.
Remote-Sensing MRV
The measurement, reporting and verification layer: LiDAR, satellite imagery, and machine learning that assess and forecast project quality independent of the developers being graded.
Independence as a feature
Renoster describes itself as an AI-native climate technology company, and the phrasing matters. The science is not a marketing garnish; it is the moat. By maintaining independence from project developers during the rating process - no cozy NDAs, no revenue tied to a favorable grade - the company kept its ratings free of the conflicts that quietly hollow out other agencies.
That independence is also a culture. This is a small team, around 13 people, willing to publish inconvenient conclusions and to sunset its own products on principle. It is the kind of company that treats "show your work" not as a slogan but as an operating constraint.
The business model has evolved with the mission. Renoster began by selling rigorous, unbiased reviews to buyers, investors, and developers. Today, through Apollo, it originates and monetizes verified removals directly - using the same remote-sensing technology it once pointed at everyone else, now pointed at forests it stands behind.
The road so far
Who bet on doubt
Renoster's $3.9M in total funding - anchored by a $3.8M seed in July 2023 - came from a roster of climate-minded investors: Better Ventures, Cerulean Ventures, Climactic, Possible Ventures, and the Seraphim Space Accelerator. It is a fitting cap table for a company that reads forests from orbit.
The thesis was contrarian: back the company willing to say credits weren't good enough, and trust that honesty would eventually become the market's most valuable currency. As the industry has lurched from scandal to scrutiny, that bet has aged well.
Five things worth knowing
The name nods to the rhinoceros - thick-skinned and hard to fool. On the nose for a company built to be skeptical.
Co-founder Elias Ayrey earned a PhD reading forests from space at the University of Maine - which is now Apollo's home turf.
Renoster scrutinized over half a billion credits before deciding to produce its own.
Apollo asks for just 25 acres and zero upfront cost - unusually small for a forest carbon program.
The company retired its own ratings platform on principle, calling it a July 2025 "opinion" rather than eternal truth.
Back to that stand of spruce
Return to Maine. The forest that was getting older on purpose is still standing - but now the reason it stands is different. It is not protected because a distant buyer took a promise on faith. It stands because a landowner was paid to be patient, because a laser can prove the trees are still there, and because a company decided that the honest thing to do with an unconvincing market was to build a better piece of it. Renoster started by refusing to look away from the numbers. It has ended up, at least in one corner of Maine, changing what the numbers say.
