Poplar Room

If you read one Carbon inventories company this quarter, make it this one.

a short list names asked to be first. None of them bought a token here. They asked for the product.

Poplar 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 8). This is when the story, the customers and the legal path get written down — or the file stops.

8 live counterparties in the thread. The public page is the overflow.

Diligence, not a prospectus. RCA Pad does not allocate, take orders, or close funding. If this company raises, it raises with its own counsel.

Producer seat

A national registry as counterpart is the whole company.

Why the desk took it

A real job, not a ticker.

No public token representing a tonne. We searched.

Traction

2 named pilots (redacted).

Founded 2026, headquartered in Seoul. 2 named pilots on file (identities redacted in public). 8 nodes or connected surfaces reported. Desk diligence score 80/100. Sprint day 8 of 14. A national registry counterpart, not a scrape. They killed their own ‘token as fee’ sentence before we asked. Rare, and it scored.

Next 12 months

One retirement an offtaker will show their auditor.

A public carbon coin is a commodity or a security. This pad will not sell it. Bps on a job that already has a budget line. A public coin would not make the invoice larger.

The brief

How a serious reader should hold this.

You can wait for a sticker. The named customer did not. They are writing into this record while the rest of the market argues about a comment period.

Poplar Room exists because the incumbent brand will not staff the unglamorous middle of Carbon inventories. The product is that middle. The token, if it ever exists, is not the product — and is not for sale here. The people in the queue already understood the difference.

The auditor of a redacted pilot has seen a dual-record. Switching away now means a new auditor conversation. That is the switching cost — not the logo.

From the founder

US persons are outside the audience. A form that asks “are you accredited?” without verification is not an exemption.

From ops

Fixed fee. Deposit to start. 0% of proceeds. Token-only pay is declined. Percentage of raise is declined.

From counsel

We will not describe this as Reg CA-compliant, MiCA-stickered, or FCA-authorised. Issuers retain their own counsel in every relevant jurisdiction.

The window

Miss this and you read the archive.

If the window closes you still have the pack — as history. Not as a live conversation.

0% of proceeds. Fixed fee. The incentive is a clean campaign — not a raise.

Read it once, properly, while the number is still green. Then decide.

The bet

Why this company exists.

A national registry as counterpart is the whole company.

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. Poplar Room is priced as software against an invoice that already exists.

The live path is Not offering — locked. Proposed Regulation Crypto Assets is not treated as a calendar slot. Build as if it never opens.

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
06The legal source of truth stays with the incumbent register, admin, or custodian.

Operating week

What “in market” actually looks like.

SatDarkNo creators. No threads. Restricted geos stay dark.
SunOwnersWho can decide messaging and budget on a recorded line. If the answer is nobody, stop.
FriKill switchRehearse unpublish in 24 hours. If it takes a committee, it is not a switch.
WedCounselPerimeter diffs. If the site drifted from the memo, the site moves — not the memo.

The wedge

Why this one, not the other one.

They sell: Producer seat
Who pays: A national registry counterpart, not a scrape.
Unit economics: Bps on a job that already has a budget line. A public coin would not make the invoice larger.
Moat on file: An offtaker has retired a certificate via this event.
Switching cost: Network effects only if a second named counterparty writes. One customer is a service firm.
Vs the comps: A public carbon coin is a commodity or a security. This pad will not sell it.
Why we listed it: No public token representing a tonne. We searched.

Next twelve months

What has to be true.

One retirement an offtaker will show their auditor.

They killed their own ‘token as fee’ sentence before we asked. Rare, and it scored.

They have not asked us to run a sale. That ask would close the file.

Risks

What can kill it.

The one that actually kills it

The unit of account becomes a token

Seat plus event. If they attach a token as the unit of account, this company is a different company — and not one we will operate a campaign for.

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, Poplar Room is a liability. Dual-record or nothing.

Token relapse

A later round that wants a public token puts Poplar Room in a different perimeter. The file treats that as a hard stop.

Ask these next

01Where do keys, title, or NAV liability sit — and is that person licensed?
02Who can unpublish a public sentence in 24 hours, by name?
03If RCA Pad disappeared tomorrow, could the customer still run the job?
04What does renewal look like if no round ever happens?
05What happens if a founder later wants a public token?
06Which geography is actually locked, and which is a hope?

Who can decide

Mei Novak (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.
