The problem
QS work lives in spreadsheets and inboxes, and the truth drifts.
Excel dominates
Copying, pasting, comparing budgets against actuals, reconciling by hand. The live number is only ever as current as the last save.
Approvals get lost
When a dispute lands, finding what changed and who approved it takes hours of email and version archaeology.
Change tracking is weak
Variations, version control and final-account reconciliation are the sharpest, most costly pains in the whole workflow.
Watch the record work
A change lands. Everything downstream updates.
This is the platform promise in one loop: a variation is raised, priced and approved, and the live budget and rolling final account move with it.

The vision
One record. Every stage. Always current.
Quantity surveying is not one process, it is a chain of connected commercial workflows. Obedience holds them in a single live record so a change in one place updates everywhere downstream, automatically.

Final Account
A variation is a diff
Between two versions of the record. Raise it, price it, approve it, issue it, and the totals move with it.
A live budget
Budget versus actual, updated as variations are approved. No more month-end spreadsheet reconciliation.
A rolling final account
The projected final account, current today, not reconstructed at the end from a paper trail.
Why Obedience
Bring the walls down.
In the built environment, nothing stands by accident. Buildings rise, and cities hold, because people follow the system: the regulations, the specifications, the sequence, the coordination. That discipline has a name. We call it obedience.
The barriers are real too. Stalled schemes, planning refusals, disputes buried in email, budgets that drift from the truth. Like the walls of Jericho, they rarely fall to force. They fall to strategy, coordination, and a record everyone can trust.
Our AI is obedient: it assists, it shows its work, and it never overrides the professional who signs. We bring the barriers down not by replacing judgement, but by giving it one live, disciplined record to stand on.
Our mission
To bring the built environment’s commercial record into one live, disciplined system, so the barriers that stall projects come down. We start with quantity surveying.
How we built this, and how we work alongside practitionersGrounded in direct discovery with practising UK quantity surveyorsBuilt on a deep NRM2 knowledge baseData locations disclosed
The platform
AI where it earns its place, sign-off where it counts.
We ship the highest-leverage capabilities first and label them honestly. Nothing here claims to be live until it works end to end.
Live
NRM2 BoQ builder
NRM2-native measurement and Bills of Quantities, with version history and a live calculation store behind every total. This is QuantifyQS today.
In development
AI Change Control
Variations as diffs between versions: raise, price, approve, issue, with rolling totals. Built on the BoQ version foundation. The MVP we are building next.
Roadmap
AI Commercial Search
Ask the commercial record in plain English: what changed, who approved it, what it cost. Answers that cite their source.
Roadmap
Document ingestion & take-offs
Contracts, drawings, minutes and emails ingested and linked to the project, plus PDF take-off measurement tools.
The products
One platform. A growing set of instruments.

Obedience Cloud
The platform our products run on: a London-region project database, Western Europe object storage, EEA runtime, tenant isolation, encrypted backups, and the trust surface where our security posture lives in the open.
Trust
Built for people who are accountable for the number.
AI assists, humans author
AI drafts; a named person accepts. Nothing client-facing is signed without a human.
Data locations stated plainly
Structured records use London Postgres; file objects use R2 in Western Europe; Cloud runtime is in Germany.
Tenant isolation
Row-level security in the database itself. Your data can never leak to another practice.
Encrypted backups
Daily, off-site backups, encrypted at rest and restore-tested.
NRM2 native
Built on NRM2 structure and measurement rules, not bolted on.
Responsible AI
Every AI output shows its source and requires sign-off. Judgement stays with the professional who signs.
Every policy behind these commitments is public in our policy hub: privacy, security, data processing, responsible AI, RICS alignment and more.
