AI designed specifically for the task at hand

A general chatbot is not accountable for the client report.

Generic AI toolPantera's harness

Where numbers liveProse in a chat window, re-typed into a spreadsheet.A typed valuation: term and reversion, unit-level leases, evidenced yields and ERVs.

The arithmeticYears’ purchase and deferment computed by a language model.Deterministic valuation engine — hardcore and topslice, YP, deferment, growth explicit.

EvidenceComparables invented or half-remembered.ERVs and yields derive only from comparables you supplied, with weightings recorded.

StandardsNo awareness of Red Book requirements or MEES.Basis, date, assumptions and special assumptions captured as structured fields.

ReversibilityNo record of how the figure was reached.Full audit trail of every input, source and approval — defensible years after signature.

ConfidentialityClient and lease data in a general-purpose model.UK-hosted, never used for training, SSO and role-based access.

Deterministic maths

The cashflow engine does the arithmetic, not a language model. Same inputs, same answer, every time.

Provenance

Every populated value keeps its document, page and cell reference. Hover any number and see where it came from.

Approval gate

Nothing enters a shared model until a human approves the step. Reverting is one click, and logged.

A valuation is a professional opinion you sign. The evidence behind every input has to be retrievable. That is exactly what a general-purpose chatbot cannot give you.

Why vertical AI wins

The modern way to value

The workflow every valuer has been waiting for

The same rigorous methods your professional standards demand, on a platform built for how valuers actually work today. Import the evidence, set the assumptions, and interrogate the result.

Build the foundation from your documents

Import tenancy schedules, property management reports, leases and rent rolls. Pantera reads them and structures every income event, so the valuation starts from your evidence, not a blank spreadsheet.

Set assumptions in numbers or in words

Key in yields, ERVs and allowances directly, or describe the assumptions you want in plain English. The auditable Pantera engine does every calculation and produces the value, the same way every time.

Trace every figure back to its source

No black box. Every capital value opens up to the income events, rates and adjustments behind it, and each one links back to the lease or document it came from. Fully auditable, ready to defend.

Interrogate it and benchmark it

Ask questions of the valuation in plain English to understand what drives the figure. Compare it against live market evidence and your own previous valuations of the asset, so you can see and explain exactly what has changed.

The output

A clear, defensible value hierarchy

Gross value, adjusted gross value, capturing factors like lease-break penalties, then net value after purchaser's costs. Every headline number traces back to the individual income events behind it.
