One figure, settled before the work starts and printed after it, whichever way it came out. That is the whole offer, and everything below is the arithmetic behind it.

Casework 

Five engagements, side by side.

Each one with the client named, the figure agreed at the start, and what it came to.

01 / 06
  1. Insurance 01 / 2025

    Claims triage copilot at Meridian Mutual

    Client Meridian Mutual
    Measure −41% claims-processing time

    A copilot that reads the claim, proposes the route and shows its evidence: built with the claims team, handed to them in twelve weeks.

  2. Financial services 02 / 2025

    Model-risk framework for Cobalt Bank

    Client Cobalt Bank
    Measure 14 days to audit-ready, from ninety

    A model register with risk tiers, an audit trail from data to decision, and a policy set mapped to the regulation clause by clause.

  3. Energy & utilities 03 / 2024

    Maintenance regime redesign at Halvard Energy

    Client Halvard Energy
    Measure −23% unplanned turbine downtime

    A fixed maintenance calendar replaced by a schedule built on the machines' own readings, and argued with by the crews who run it.

  4. Logistics & transport 04 / 2024

    Network redesign at Northline Logistics

    Client Northline Logistics
    Measure +9.6pp on-time delivery across the network

    Forty depots, two disagreeing forecasts, and a network resequenced around the hours the depots actually had.

  5. Retail & consumer 05 / 2025

    Range and pricing strategy at Ostro Retail Group

    Client Ostro Retail Group
    Measure +3.4pp gross margin, twelve months after repricing

    The margin map showed that a fifth of the range was paying for the rest. The pricing was tested on the shelf before it went in a deck.

audits whose first recommendation was something we do not sell

Tell us the problem, not the brief.

Two paragraphs about what is going wrong is the most useful first message. A partner reads it, and you hear back within two working days, including when the answer is that we are not the right firm for it.
