How we work

Find out what is wrong while it is still cheap to be wrong.

Five phases. The first resists the brief, the second tries to kill the idea, and the fourth deliberately breaks the system before your customers do. Everything else follows from those three decisions.

Phases

05

Delivery cadence

Two-week increments

First decision gate

End of Prove

Engagement ends

On handover, not on budget

01The method

What happens, in order.

Each phase has an exit question. We do not move on until it has an answer we can defend — and 'stop here' is always one of the permitted answers.

  1. Frame

    1–3 weeks

    What is actually the problem, and how will we know if we solved it?

    We resist the brief long enough to test it. Most engagements arrive as a proposed solution; the work of the first weeks is separating that from the underlying problem and agreeing what evidence would count as success.

    In practice

    • Stakeholder interviews across business, engineering and risk
    • Constraint mapping — regulatory, data, integration, budget, political
    • Success measures defined and agreed in writing before work starts
    • Explicit statement of what is out of scope
  2. Prove

    3–6 weeks

    Does this work on our data, in our environment, at our constraints?

    A thin but real slice, built in your environment on your data. Not a demo on synthetic inputs — a narrow vertical cut through the whole architecture, which is the only thing that surfaces the integration and performance problems early enough to matter.

    In practice

    • Working thin-slice through every layer of the proposed architecture
    • Evaluation set and baseline measurement established
    • Unit-economics model at pilot volume and at target scale
    • Honest go / no-go recommendation, including 'no'
  3. Build

    Two-week increments

    Is it getting better, and can we see it?

    Working software in your environment every two weeks. Your engineers are embedded in the team from the first increment, not briefed at the end — because the handover starts on day one, not at the close of the engagement.

    In practice

    • Two-week increments, each demonstrated in a real environment
    • Continuous integration, automated quality gates and progressive delivery
    • Joint teams — your engineers commit alongside ours
    • Documentation and runbooks written as the system is built
  4. Harden

    2–4 weeks

    What happens on the worst day?

    The phase most programs skip and most incidents come from. Before anything carries real load we deliberately try to break it — security, failure modes, recovery, and the operational reality of the team who will hold the pager.

    In practice

    • Threat modeling, penetration testing and dependency review
    • Load, chaos and failure-mode testing against defined SLOs
    • Incident runbooks, alerting thresholds and on-call readiness
    • Compliance evidence pack and formal control sign-off
  5. Operate & hand over

    4–8 weeks, tapering

    Can your team run this without us?

    We reduce our own involvement on a published schedule. Success is measured by your team's independence — the engagement ends because it is finished, not because the budget ran out.

    In practice

    • Production operation with a deliberately tapering Mercrest presence
    • Capability transfer sessions and paired on-call rotations
    • Post-launch measurement against the success criteria set in Frame
    • Written exit: architecture decisions, known limitations, next horizon
02Why it holds

The method only works because of how the firm is built.

A five-phase process is easy to publish and hard to honour. These are the structural choices that make ours survive commercial pressure.

01

One team, strategy through production

The people who recommend it are the people who build it.

There is no handoff from a strategy team to a delivery team, because they are the same team. It is the single structural reason our estimates hold up: nobody in the room is insulated from having to execute what they proposed.

02

Vendor-neutral by policy

No reseller margin. No platform quota.

We earn nothing on the licenses you buy, so our recommendation is not shaped by what we would make on it. That is what leaves 'buy rather than build' and 'stay where you are' genuinely available to us as answers.

03

Security and compliance as design inputs

Controls are architected in, not bolted on.

Regulatory posture, data residency and the control environment are settled during design. Retrofitting them onto a working system is the most reliably expensive thing we see in this industry.

04

Economics engineered in

Cost per transaction is a design constraint.

Unit economics are modeled before the architecture is fixed and tracked in production afterwards. A system that works beautifully and cannot be afforded at scale has not been engineered — it has been prototyped.

05

Built for handover

Our objective is your independence.

Your repositories, your cloud accounts, your documentation, your people trained to run it. No proprietary runtime, no black box, no dependency engineered to keep us on the invoice.

06

Small senior teams

Seniority over headcount, always.

Engagements are staffed with practitioners who have built the thing before, not with a pyramid of juniors under a partner who appears at steering committees. It is a deliberate constraint on how fast we can grow.

03Advisory

Consulting is how we work, not a product we sell beside the others.

We do not list technology strategy as a capability, because a recommendation from people who will not build it is the failure mode we exist to remove. Advisory work runs through every engagement instead.

01

Technology strategy & roadmap

A sequenced, costed plan connecting business objectives to what engineering actually does next quarter — with the investment case a CFO can read and the trade-offs stated rather than buried.

02

Engineering effectiveness

Raising the throughput of the teams you already have, usually the highest-return intervention available. Delivery-flow diagnostics, DORA instrumentation, platform investment cases and team topology.

03

Written to be argued with

Every recommendation carries its assumptions, its alternatives and the conditions under which it would be wrong. You should be able to challenge it, and the people who wrote it will be in the room when you do.

04Engagement models

Four commercial shapes.

Diagnostics are fixed price. Build teams are time and materials against a published rate card. We do not quote fixed price for work whose scope we cannot yet honestly define — that pricing model only ever produces a fight later.

DiagnosticFixed scope · 3–4 weeks
A short, independent assessment producing a decision you can act on and a costed path forward. The usual way clients start with us.
Build teamDedicated squad · 3–12 months
A senior cross-functional team embedded alongside yours, shipping in two-week increments with joint ownership throughout.
Advisory retainerNamed partner · ongoing
Continuous architecture, security and technology-strategy counsel for leadership teams, without a delivery commitment.
Managed operationSLA-backed · ongoing
We run what we built — monitoring, incident response and continuous improvement — until your team is ready to take it, or for as long as you want us to.
Start

The first three weeks tell you whether the next twelve months are worth it.

Most engagements start with a short, fixed-scope diagnostic — three to four weeks, a written recommendation, and a costed path forward. If we are not the right firm for it, we will say so and point you somewhere better.
