Testimonials

How ClaimMaster.ai reflects project reality.

“

ClaimMaster.ai changes the timing of claim building. Instead of reconstructing logic at the end, the evidential position is shaped while delivery decisions are still being made.

Commercial Director Main contractor, London (UK)
“

The platform does not just store records. It structures cause, effect, support, and narrative continuity in a way that is far more useful under scrutiny.

Construction Claims Consultant Claims and dispute support

We trialled the approach on a live job and immediately saw how many events our teams would normally mention verbally but never preserve properly.

Managing Director Groundworks subcontractor
Built From Real Practice

Why ClaimMaster.ai exists.

ClaimMaster.ai was built from years of watching the same commercial failure repeat across construction projects—but high-risk specialist subcontractors paid the highest price.

We worked alongside main contractors, subcontractors, consultants, developers, and project owners. Time after time, the subcontractors closest to the work absorbed the disruption, coordination failures, late design information, acceleration pressure, and changing site conditions.

Then the project turned hostile, blame moved downstream, and their position collapsed under scrutiny. Not because the work lacked merit. Rather because the evidence trail failed.

Verbal instructions replaced clear records. Notices went out late. Emails became fragmented. Teams changed. Project memory disappeared. Payment got withheld, variations were rejected, and valid entitlement became difficult to defend months or years later.

ClaimMaster.ai was built to stop that from happening—by helping subcontractors capture project events, structure evidence, and preserve defensibility while the project is still live.

FAQ

Your questions, answered.

No. AI supports drafting and structure, but professional judgement stays with you. The platform is governed to ensure outputs align with defensibility, not automation for its own sake.

No. It replaces scattered notes, emails, and rework later. Instead of rebuilding a position under pressure, you capture it properly once, while the job is live.

Generic AI tools can help you write. They don’t structure your position, enforce causality, or link entitlement to evidence. ClaimMaster.ai is built specifically for construction claims, so what you produce stands up under scrutiny.

ClaimMaster.ai is designed around how claims are tested under scrutiny. Every record follows a structured logic—cause, effect, entitlement, substantiation, and mitigation—with timestamps, audit trail, and preserved context. It doesn’t guarantee outcomes. But it ensures your position is clear, consistent, and defensible when reviewed.

Most value is lost when positions are unclear, challenged, or rebuilt too late. ClaimMaster.ai reduces that loss by helping you:
  • Capture events properly while the job is live
  • Avoid rework under pressure
  • Strengthen negotiation positions
  • Improve recovery on variations, disruption, and loss and expense

    • The return isn’t grounded in theory. It shows up in the time and money you protect—and the relationships you don’t lose.

    For contractors, subcontractors, and commercial teams. You can use it as a single user or deploy it across a team with structured workflows and approvals.

    Full access to the platform, including the Event Record Form (CEESM), defensibility scoring, governed AI assistants, and drafting tools. You start with 3000 credits, then continue on the Pro plan at £99 per user/month.

    No. You can create unlimited records. The focus is not volume—it’s building records that hold under scrutiny.

    Yes. ClaimMaster.ai can be deployed as a whitelabel solution with custom workflows, approvals, and governance aligned to your contracts and internal processes.

    ClaimMaster.ai doesn’t replace your systems. It sits alongside them as the defensibility layer.
    You can continue using your existing tools for programme, cost, and document management—while ClaimMaster.ai structures the narrative, evidence, and contractual position that sits behind them.
