Three active service lines operating in the United States today. Direct relationships, real outcomes, no intermediaries.

The Bigger Picture
From the US to the World

How our US operations connect to Caribbean expansion and a long-term thesis in global climate infrastructure. For investors and strategic partners.

The Green Keel Venture

Regenerative
infrastructure.
Verifiable
at the source.

"Every node generates revenue. Every node generates data. The data from one node makes the next node possible."

Architecture

Five nodes.
One circular
model.

Green Keel operates across five interconnected nodes — each a distinct business with its own customers and economics, each contributing to the next. The model is designed to scale through community partnership rather than ownership of any single parcel. What connects the nodes is not a theory. It is the work already underway.

01
Grizzley ACE
Active
Extraction
Where It Begins

Every material economy starts with extraction. Ours starts responsibly — drawing from land our family has stewarded for years, in partnership with the communities that depend on it. Grizzley ACE supplies aggregate to construction and infrastructure operators across Jamaica and the wider Caribbean. What makes it different isn't the material. It's the documentation — every extraction event recorded, every practice accountable. That data is the foundation everything else is built on.

02
Grizzley Auto
Active
Circular Fleet
Climate Work Disguised as Commerce

US commercial fleet operators retire equipment that still has years of productive life left. Caribbean construction, agricultural, and logistics operators need exactly that equipment and can't easily access it. Grizzley Auto closes that gap — sourcing, refurbishing, and redeploying vehicles and heavy equipment across the corridor. Every unit that moves through this node avoids the carbon cost of manufacturing something new. The business case and the climate case are the same transaction.

03
Land Condition Registry
In Development
Stewardship
Making Stewardship Legible

Communities across the Caribbean have been caring for land for generations. The problem is that care has never been legible to global capital markets — no documentation, no baseline, no proof. The Land Condition Registry changes that. It builds the evidentiary layer that turns responsible land use into a verifiable asset. And it's designed to scale through partnership, not ownership. Any steward, any parcel, any community — the registry works for all of them.

04
Green Trace
In Development
★ The Connective Tissue
Measurement at the Source

Green Trace is field-deployable infrastructure designed to quantify material movement and ecological activity at the point it happens. The same data that serves a commercial purpose also serves a climate one. We are building it because the operations we already run make us the right people to build it.

05
MRV Platform
In Development
Carbon Intelligence
Closing the Loop

When stewardship is documented and measurement is verified, the final step is translation — turning that verified ecological work into the financial instruments that global markets understand. Carbon credits, MRV data licenses, sustainability-linked finance pathways. This is where the work done in every prior node finds its highest-value expression. And critically, the revenue flows back — to the operators, the stewards, the communities. That's what closing the loop actually means.

About Green Keel

Built over years.
Owned by family.
Scaling with intention.

“To cultivate and to keep.”

Genesis 2:15  ·  The founding ethos

Green Keel Holdings is a family-built operating company — not a startup in the conventional sense, but a multi-generational enterprise assembled deliberately, across years, geographies, and disciplines.

The company's thesis begins with a simple observation: the world has a measurement and stewardship problem. Billions of dollars in climate finance cannot flow to the communities that need it most because the infrastructure to verify what happens on the ground doesn't exist at the scale or cost that small operators can access. Green Keel is building that infrastructure — starting from the communities we are already embedded in, with a network deep enough to scale through partnership rather than ownership.

The land in Jamaica is not the ceiling of the vision. It is proof of the model. Active extraction operations, equipment moving between continents, ecological baselines being built from real operational data — the five nodes are already functioning as a system. Green Trace is what connects them to global capital markets.

The thread running through all of it is the Hebrew call of avad and shamar — to cultivate and to keep. To work the land productively and to protect what has been entrusted. That resolves every question about how to grow, and how not to.
