The platform

From scattered data to a decision you can explain.

Harrier DLI does six things, and each one builds on the last. Screenshots show Aldermere, a fictional estate in our demonstration model.

1 · One picture

Everything you hold, joined to everything the record says.

Live connections to the systems you already run, and AI agents for the documents and spreadsheets that have no connection. Every fact lands on the map with its source, marked live or confirmed.

  • Terrier, tenancies and rent roll from your terrier system (Landmark, Searchlight), and rents and costs from your finance software (Xero, QuickBooks, Sage)
  • Flood, habitat, planning, land grade and grid capacity from the public record
  • Tenancy agreements, valuations and surveys read by AI agents and checked by your team

2 · Screen

Every field, tested against every use.

Habitat bank, landscape recovery, woodland carbon, solar, development, farming in hand. For each field, Harrier shows whether the record and your terrier allow it, and why.

  • Viable, constrained or ruled out, with the source of every reason
  • The realities a land agent checks first: tenancy terms, AHA succession, grid headroom, best and most versatile land
  • A screen to argue with, not a recommendation to accept

3 · Compare

Start from what you want. See what it costs, and a cheaper way to get there.

Most strategies begin as a wish: rewild a third, keep it together, farm it ourselves, pay the next tax bill. Harrier builds the wish as you would first draw it, prices it against holding the line, and finds the version that gives up least.

  • Every option in cash and over time, with secured income kept apart from market income
  • Assumptions phased by confidence: evidenced, judgement and placeholder
  • Describe a scenario in plain words, and Harrier builds it field by field

4 · Test

Run every option through the futures that worry you.

Drag a recession, a change to inheritance tax relief or a habitat price collapse onto the timeline, and watch every option respond. See which holds up when things go wrong, not just which scores highest when they don’t.

  • A profit and loss forecast for every option
  • Dated futures you can move, combine and switch off
  • A plain statement of which option is robust, and which assumption would overturn it

5 · Plan

Know what is coming, and when you can still walk away.

Every tenancy end, succession, lease, plan review and agreement on one calendar, then worked back into a transition plan for the option you choose: the notices, the surveys, the applications, and the agreement that makes it binding.

  • Steps by year, with who does each one
  • Every point of no return marked before you reach it
  • The cash dip on the way, and when you are back ahead

6 · Record

The reasoning, kept for whoever asks next.

Each decision recorded with what was decided, the options on the table, why, and what was known at the time. Go back to any year and see the land as it was and the policy in force, then compare it with today.

  • A decision record built as you work, not written afterwards
  • Then and now: what has changed since each decision
  • Something to point to when a trustee, beneficiary or successor asks why

In the field · Harrier Air

The model, in the landscape.

Harrier Air puts the same picture on a phone, in the field. Point it at a field to see what the model knows about it, the habitat, the tenancy and what the plan says, then confirm or correct it on the spot. Every observation flows back into Harrier.

  • Ground-truth the data where it matters
  • Take the offer to the farm gate, not just to the board
  • Renewals, surveys and monitoring captured as they happen

Integrations

Live where your systems allow. AI agents for everything else.

Harrier is built to sit above what you already run, so getting started is a matter of days, not a data project.

Your systems

Connected live through their APIs, and kept in sync.

Terrier systems

LandmarkSearchlightand others

Finance software

XeroQuickBooksSage

Document stores

SharePointGoogle Drive

Your unstructured data

Documents, spreadsheets and offline records, read by AI agents. Each fact shows where it came from, and your team confirms it.
Tenancy agreementsValuation reportsHabitat and ecology surveysFarm carbon auditsScheme and stewardship agreementsSpreadsheetsGIS and shapefile exportsBoard and committee papers

What “confirmed” means

When an agent reads a document, the fact it finds is shown with its source and held until someone on your team confirms it. Nothing enters a decision unchecked.

The public record

Connected live and refreshed as it changes.
Environment Agency flood zonesNatural England designations and habitatsNutrient catchmentsDefra agricultural land classificationHM Land Registry title polygonsRPA land parcelsNetwork operator capacity mapsHistoric EnglandEPC registerLocal plan allocations

Live connections depend on each system’s API. Where a system has none, Harrier reads its scheduled exports instead.

Your data

Yours, inspectable, and never behind a veil.

It stays in your systems

Harrier reads from the systems you own. Your terrier and accounts remain the record; Harrier is the view across them.

Every number has a source

Every figure traces back to where it came from and the assumptions behind it. You can see, and change, every assumption.

Export whenever you like

The picture, the plans and the decision record Harrier builds with you can be exported at any time. No lock-in.
