Seven disciplines under one delivery team — build, secure, migrate and grow without handing your project between vendors. Written architecture, fixed estimates, and code that stays yours.

ARB — Architecture, Resilience, Build. The three things we insist on, in that order.

0

Disciplines, one delivery team

Build, secure and grow without handing your project between vendors.

0 day

Response to every enquiry

A named engineer replies within one business day, not a sales sequence.

0 wks

Fixed-fee discovery

A written architecture and a real estimate before anyone commits to a build.

0 cost

Retest on security work

We retest and reissue the report once your fixes are in. Included.

02How we work

Six commitments we put in writing.

None of these are aspirations. They are the terms we work under, and you are welcome to hold us to any of them.

01

Estimates before invoices

Scope, assumptions and price are agreed in writing before a build starts. If the scope moves, you see the cost of the change before we make it — never after.

02

Small releases, often

Work ships in slices you can use and judge. Nothing disappears into a six-month black box and re-emerges as a surprise.

03

Security is not a phase

Threat modelling happens during design, dependency and secret scanning run in CI, and our own security team reviews what our developers build.

04

No lock-in by design

Your repositories, your cloud accounts, your domains, your data. Standard tooling, documented decisions, and a handover you could act on tomorrow.

05

Written down beats remembered

Architecture decisions, runbooks and trade-offs live in the repository. Institutional memory should not depend on who is still on the call.

06

Say the difficult thing early

If a deadline is unrealistic or a feature is not worth building, you hear it while it is still cheap to act on. Comfortable silence is the expensive option.

03Process

A delivery process you can audit.

Six phases, each with a defined output. You always know which one you are in, what it produces, and what it costs.

04Engagement models

Three ways to work with us.

Pick the shape that fits the problem. If you are not sure which applies, say so on the brief and we will recommend one.

01Fixed fee, invoiced per phase

Fixed-scope project

Defined outcome, known deadline

Scope, price and schedule fixed after discovery. Best when you know what needs to exist and when it needs to exist by.

  • Written scope and architecture
  • Fixed price per phase
  • Change requests priced before work starts
  • Warranty period after launch
02Monthly rate per squad

Embedded team

Evolving roadmap, continuous delivery

A cross-functional squad working in two-week cycles alongside your people, with priorities you set at the start of each cycle.

  • Named engineers, not a rotating pool
  • Your board, your ceremonies
  • Security and QA capacity included
  • 30 days' notice either way
03Fixed fee per assessment

Assessment & advisory

A decision to make, or risk to quantify

A time-boxed engagement that ends in a document: a security assessment, an architecture review, a build-versus-buy recommendation, or a migration plan.

  • Fixed-length engagement
  • Findings ranked by impact and effort
  • Presentation to technical and executive audiences
  • Retest or follow-up review included
05FAQ

Questions we get asked before the first call.

Something not covered here? Ask directly — a person answers, and it is usually the same person who would do the work.

Discovery usually begins within two weeks of a signed scope. Security assessments can often start sooner, since they need a shorter run-up.

Next step

Tell us what you're building. We'll tell you what it takes.

Two lines is enough to start. You'll get a cost range, the assumptions behind it, and a straight answer on whether we're the right team for it.
