Six things we build.

Each service is led by experienced engineers, and every project ends with something you own.

Compare all six services

Web development

A new website, or a rebuild of one you have outgrown. Fast, and easy for your team to update.

What you keep

The site, its content and its code.

How we approach websites

Mobile apps

iPhone and Android apps, from the first release to every update after it.

What you keep

The app, under your own developer accounts.

How we approach mobile apps

Custom software

One simple system in place of the spreadsheets and email chains your team relies on.

What you keep

A documented system that grows with you.

How we approach custom software

Cloud & hosting

Reliable hosting in your own account, with fast updates and tested backups.

What you keep

Your infrastructure, in your own account.

How we approach cloud and hosting

AI & automation

Reading documents, sorting requests and drafting replies, tested on your own records first.

What you keep

A tested feature, with proof of how well it works.

How we approach AI and automation

Integrations

Your tools share data on their own, so nobody has to copy it by hand.

What you keep

Documented connections and a log of every sync.

How we approach integrations

Everything in your name, from day one.

Your code, hosting, domains and app store accounts are registered to you before work begins. If you ever move on, there is nothing to transfer.

Held by ArthmarkNothing.

One stage at a time.

Four stages, each with a clear result. After every one, you decide whether to continue.

See the full process
  • 01First call

    Tell us what you need

    Explain the problem in your own words. No technical brief is needed. We ask questions, review anything you already have and send you a written plan.

    • A 30-minute call about your goals
    • A review of your current system, if you have one
    • A written plan with the approach and the risks
    • A fixed price for the next stage

    If you stop here, you keep

    A written plan you own, whether or not you continue.

    Cost. No charge, and no commitment.

  • 02Next

    We build the hard part first

    Every project has one part that decides whether the rest will work. We build it first, so you see real, working software before you commit further.

    • Designs for the main screens
    • The data structure, agreed early
    • Working code for the riskiest part
    • A walkthrough before you decide

    If you stop here, you keep

    Working software you can try, in your own account.

    Cost. Fixed price, agreed after the first call.

  • 03Main build

    We build the rest in stages

    Each stage is scoped and priced before it begins. If a stage takes longer than planned, the price stays the same.

    • Scope and price agreed before each stage
    • Working software at the end of every stage
    • Your team can use it while the rest is built
    • Stop after any stage, with no penalty

    If you stop here, you keep

    Working software, and everything built so far.

    Cost. Fixed price per stage.

  • 04After launch

    We support it or hand it over

    Some clients keep us on for ongoing support. Others bring the work in-house. We plan for both from the start, so either path is smooth.

    • Documentation written as we go
    • Handover sessions with your team
    • Or an optional monthly support plan
    • Everything stays in your accounts

    Either way, you keep

    Complete documentation, and a system that is entirely yours.

    Cost. Optional monthly support.

We know the rules lending runs on.

Loan applications, approvals, repayments and money movement, built around the regulations that govern them.

  • Loan applications
  • Approvals
  • Repayments
  • Money movement
  • Compliance
  • Reconciliation

Have another question? [email protected]

  • There is no charge for the first call. After it, you receive a written plan with a fixed price for the first stage. Each later stage is priced before it begins, and an agreed price never goes up.

Tell us what you want built.

You will hear back within one business day from an engineer who would build it.
