In diligence
IN MOTIONCarbon inventoriesYarrow Room
A named Copenhagen buyer is on the record. You are still reading the public page.
Elena Holm will not run a public sale on this pad. The listing exists because of that sentence.
Yarrow Room — A ledger of energy certificates (GOs, RECs) for producers and offtakers who already sit in a national registry. It moves the event faster. It does not invent a green token for Twitter.
In a 14-day diligence sprint (day 5). This is when the story, the customers and the legal path get written down — or the file stops.
A year from now this will be an obvious company or a missed one. The window decides which.
Diligence, not a prospectus. RCA Pad does not allocate, take orders, or close funding. If this company raises, it raises with its own counsel.

Why the desk took it
A real job, not a ticker.
No public token representing a tonne. We searched.
Traction
One named pilot (redacted).
Founded 2025, headquartered in Copenhagen. One named pilot on file (redacted in public). 4 nodes or connected surfaces reported. Desk diligence score 77/100. Sprint day 5 of 14. Two licensed PSPs on a paid pilot — identities off the public file. No public APY, no public book, no ‘how to buy’ on any surface we could find.
Next 12 months
Counsel on commodity vs software — one memo.
Xpansiv is a market. This is the event under a registry. Seat plus event. If they ever attach a token as the unit of account, the file stops.
The brief
How a serious reader should hold this.
Before the waitlist, before the window, there was a refusal. Yarrow Room would not let a public sale sit on this page. That is why a company in Carbon inventories is listed here at all — and why the people who wanted a coin left, and the people who wanted the product stayed.
What you can verify today is smaller than the slide. What you cannot verify is named as a question, not a promise. That is the difference between this company and a pad listing — and why the waitlist is not a coin queue.
US traffic was taken off the public surfaces in the first working session. Yarrow Room did not argue. Adult companies do not costume a US offering.
From ops
This communication is not an offer. Participation mechanics do not exist on this pad. If a later reader treats the public stack as the offer, the stack was already wrong.
From the pilot
US persons are outside the audience. A form that asks “are you accredited?” without verification is not an exemption.
From counsel
A dual-control drill exists on paper. Production evidence is the next artefact, not a tweet.
The window
Miss this and you read the archive.
A later reader gets the same PDF. They do not get the same access.
The comment period is not a path. This company is priced as if that is already true.
Open the diligence or watch it close. There is not a third option that still counts as early.

Our TAM is an invoice the customer already pays. A coin would not make it larger. It would make the licence harder.

The bet
Why this company exists.
Yarrow Room shortens retirement, it does not invent a tonne.
Yarrow Room shortens retirement, it does not invent a tonne.
Corporate offtakers are being asked to prove what they bought. Registries lag. A dual record that the registry still owns is sellable.
GO and REC markets are measured in tens of billions. Ops software is a thin slice with high switching costs.
Versus the field
L2 wrappers are cheaper. They are also a different perimeter — and declined here. Yarrow Room is priced as software against an invoice that already exists.
Copenhagen being the city does not make local retail a default audience. Communications capable of inducing investment activity still have a promotions problem.
How it works
- 01A certificate that exists in a registry is evented here
- 02Delivery and retirement are visible to the offtaker
- 03The registry remains the legal source
- 04No public ‘carbon token’ sale on this pad
- 05Delivery and retirement are visible to the offtaker; the registry remains source
- 06Kill of a public sentence is an hour, not a committee.
In the same conversation as
- National GO registries
- Xpansiv
- Not a public carbon coin
If they raise
Where the money would actually go.
Not a token float. A budget against work. RCA Pad still takes 0% of proceeds.
Control environment
29%
A counsel memo that can survive a later reader.
Counsel & perimeter
21%
Keeping the public story from running ahead of the claims register.
Certifications & adapters
21%
Hiring the operator who already does this job at a licensed firm.
Second market
29%
The remaining certifications and the second named market.
Operating week
What “in market” actually looks like.
- WedCounselPerimeter diffs. If the site drifted from the memo, the site moves — not the memo.
- FriKill switchRehearse unpublish in 24 hours. If it takes a committee, it is not a switch.
- TueExceptionsOvernight breaks post back into the customer’s case system. No side book.
- MonClaimsEvery public sentence checked against the register. Anything extra is unpublished.
The wedge
Why this one, not the other one.
- They sell
- Producer seat
- Who pays
- Two licensed PSPs on a paid pilot — identities off the public file.
- Unit economics
- Seat plus event. If they ever attach a token as the unit of account, the file stops.
- Moat on file
- A national registry is a counterpart, not a scrape.
- Switching cost
- The customer’s auditor has seen this book. Switching means a new auditor conversation.
- Vs the comps
- Xpansiv is a market. This is the event under a registry.
- Why we listed it
- No public token representing a tonne. We searched.
Next twelve months
What has to be true.
Counsel on commodity vs software — one memo.
No public APY, no public book, no ‘how to buy’ on any surface we could find.
If they raise, it is to hire the remaining certifications and the second market — not to float a coin.

Risks
What can kill it.
The one that actually kills it
Counsel is a slide
Unnamed counsel is how companies die in diligence. Not offering — locked has to be a memo you can file, not a slogan on the hero.
Double count
If the registry and this ledger can both be sold, the product is a liability.
Green token
A freely traded climate token is usually a commodity or a security. This pad will not sell it.
Registry cooperation
Without the registry, this is a shadow certificate.
Policy
GO rules move. The product has to move with them, not ahead of them.
Double count
If the registry and this ledger can both be sold, Yarrow Room is a liability. Dual-record or nothing.
Facts vs theatre
A proof of a fake book is still a fake book. Yarrow Room has to attach to the real one, in Copenhagen.
Ask these next
- 01Who is the first named paying customer — not a letter of intent?
- 02Which incumbent can copy this in a quarter, and what would they have to migrate?
- 03Is the waitlist demand for a product, or a queue for a coin?
- 04Where do keys, title, or NAV liability sit — and is that person licensed?
- 05Who can unpublish a public sentence in 24 hours, by name?
- 06Which geography is actually locked, and which is a hope?
Structure
How money would actually move.
Sprint is diligence, not a raise. A pack at the end is a file the company can take to its own lawyers and investors. RCA Pad does not complete funding.

Who can decide
Elena Holm (Chief executive) will take a 30-minute call and decide budget. If the only person who can accept “we are not opening a sale” is a silent co-founder in another time zone, this company would not be on the board.
A second counterparty writing into the record is the only network effect that counts. One customer is a consultancy. Two is a market.
