Decide what your land does next.
Harrier combines your private land data with public spatial datasets, so you can model land use strategies, compare scenarios and keep a record of when and why decisions were made.
More choices than ever. Most of them unfamiliar. Some bind the land for thirty years.
Habitat banking, carbon, landscape recovery, solar, a plan review, a tax bill. Every estate and every portfolio is being asked to do more with the same land. This is what we hear from the people deciding.
The unfamiliar option
Some new options come with thirty-year obligations and cash flows nobody has modelled against the strategy you already have.
“I can picture refurbishing a cottage or thinning a wood. I can’t picture carbon or habitat banking, so I end up deciding on instinct.”
Systems that don’t talk
The picture of the estate lives in five places, so every decision starts with weeks of assembling it.
“The terrier, the accounts and the habitat data are completely separate. Someone pulls them together by hand.”
Analysis that ages
The big report is a snapshot. Tenancies end, policy shifts and prices move, and it doesn’t.
“By the time the strategy is written, it’s out of date. And reporting once a year means we always respond late.”
Decisions that outlast you
Covenants, leases and planting bind successors and trustees for decades. The terms deserve more than a gut feel.
“If I sell in year fifteen, what is that land worth? Can it ever go back to farming?”
People to bring with you
Trustees, committees, family and tenants each need to see the same evidence, in a form that makes sense to them.
“The answer is often obvious in minutes. Taking people with you is the hard part.”
Reasons that get lost
When people move on, the reasoning goes with them, and the next decision starts from scratch.
“Why did we decide that ten years ago? It’s in someone’s head, or an email somewhere.”
One picture of your land, and every option tested against it.
Harrier is not another map and not another system of record. It sits above the systems you already run and turns what they hold into decisions you can act on and explain.
One picture
Flood zones, land grade, planning, designations and grid capacity from the public record, joined to your tenancies, rents and costs. Every field, every holding, every building.
Every field, screened
Each use tested against what the record and your terrier allow: viable, constrained or ruled out, with the source of every reason.
Options, in cash and over time
Start from what you want: rewild, farm it yourselves, pay the tax bill. See what it costs against holding the line, and a cheaper route to most of the same thing.
Tested against what could happen
Recession, relief withdrawn, habitat prices halving. Every option run through the same shocks. Not a crystal ball: a fair comparison you can argue with.
A plan you can act on
Every tenancy end, succession and plan review, worked back into a transition plan, with each point of no return marked before you reach it.
The reasoning, kept
Each decision recorded with what was known at the time and what else was considered. Ten years on, the answer to “why?” is still there.
Connected in days. Useful from the first week.
No big integration project, no data clean-up before you can start, and no new system for your team to learn.
Connect
Harrier connects live to the systems you already run, from your terrier system (Landmark, Searchlight) to your finance software (Xero, QuickBooks, Sage), and to the public record. Where there is no connection, its AI agents read your exports, spreadsheets and documents, and your team confirms what they find.
Ask
Start from what you want, or from what the data allows. Harrier screens every field, prices every option against holding the line, and tests them through the futures that worry you.
Act
Take the plan to the committee, the offer to the farm gate, and the record to the trustees. As tenancies end and the evidence changes, it stays live.
Keep what you have. Harrier bridges it.
Your terrier stays your terrier, and your accounts stay your accounts. Harrier reads from them, joins them to the public record, and gives you the one view none of them can.
Glebe Farm
Connected in days. No servers to upgrade. And for smaller estates, Harrier can hold the terrier itself.
Illustrative. Connections depend on each system’s API; AI agents read everything else.
For the people who decide what land is for.
Estate directors, CEOs and owners
Put forestry, farming, property, development and natural capital on one screen, so the executive committee chooses between options, not between advocates.
For estates →Land, nature and strategy directors
Hundreds of places and thousands of tenancies. See where to act first, what to offer each tenant, and how nature can earn its keep.
For portfolios →Trustees, beneficiaries and their advisers
Decisions you can explain: the options considered, what each would cost, and why the one chosen was chosen, kept for whoever asks next.
For trustees →Landowners facing a new line, and their agents
See what a route takes and pays, plan every field before, during and after the works, and know which route to back.
For infrastructure →Three minutes on what Harrier does.
The film uses a fictional estate and illustrative figures from our demonstration model.
Built to inform your judgement, not to replace it.
Comparative, not a crystal ball
Nobody can forecast thirty years. Harrier compares options fairly, on assumptions you can see and change.
Nothing behind a veil
Every number traces back to its source and its assumptions. No black boxes, and no recommendations you can’t interrogate.
You decide
Harrier puts the evidence in front of the people who know the land. Their judgement, and the reasons for it, are what get recorded.
Your data stays yours
It stays in the systems you own. What Harrier builds from it can be exported whenever you want it.
What people ask us first.
Isn’t this just another mapping tool?
No. Mapping shows you what your land is. Harrier tests what it could be: every option priced in cash, over time, against the strategy you already have, and run through the futures that worry you. The map is where you see the answer, not the answer itself.
We already run a terrier system, finance software and our own GIS. Do we have to replace them?
No. Harrier works above them. It connects live where those systems allow it and reads their exports where they don’t, then joins what they hold to the public record. Your teams keep the tools they know.
How long does it take to get started?
Days, not months. Harrier is useful on the public record alone, before anything is connected. Your terrier and accounts follow, then documents such as tenancy agreements, which AI agents read and your team confirms.
Our data is messy. Do we need to clean it first?
No. Most estates and portfolios start with exports, spreadsheets and scanned agreements. Harrier reads them as they are and shows where each fact came from, so gaps and conflicts are visible rather than hidden.
Does Harrier make the decision?
No. It shows the options, what each would cost, what could go wrong and when you would need to act. The people who know the land, the tenants and the family decide, and Harrier records why.
Who is it for?
Organisations that make land decisions across a large holding: estates with a CEO or estate director and an executive committee, conservation and public landholders with portfolios of places and tenancies, and the trustees and family offices who oversee them.
How is it priced?
A set-up fee to connect your systems and model your first decision, then an annual licence. We would rather start with one real decision than sell you a platform. Talk to us about yours.
Can I see it working on my own land?
Yes. Bring one decision you’re facing, such as a tenancy coming up, a habitat bank offer or a plan review, and we will show you how Harrier would approach it on your land.
Keep what you have. Decide what comes next.
Bring one decision you’re facing. We’ll show you what Harrier would make of it.
