Where we help

Problems we usually get called in for

Most projects start with one of these. If yours looks different, tell us on the first call.

  • Off-the-shelf tools stopped fitting

    Your team runs the business on spreadsheets, three SaaS subscriptions and copy-paste between them. We build the one tool that matches your process and connects the data you already have.

  • A product idea with no engineering team

    You know the market and the users, but you have no developers yet. We take the idea from a written scope to a product people can sign up for and pay for.

  • A codebase nobody wants to touch

    Releases break things, the original developers have left and every change takes weeks. We audit the code, fix what blocks you first and set up tests and deployment so changes stop being risky.

  • Your in-house team is at capacity

    Your engineers are busy with the core product and a second project keeps slipping. We take a clearly scoped piece of work and deliver it inside your repository, following your conventions.

What we build

What you can hire us to build

Every project ships with the source code, a deployment pipeline and written documentation for whoever maintains it next.

  • SaaS products

    Multi-tenant web apps with sign-up, roles and permissions, subscription billing, admin panels and the usage tracking you need to run a software business.

  • Web applications

    Customer portals, booking and ordering systems, dashboards and marketplaces, built to load fast on a phone and to meet WCAG 2.2 AA accessibility.

  • Internal tools

    Back-office apps for operations, sales and finance teams that replace spreadsheets, with audit logs and access control.

  • APIs and integrations

    REST and GraphQL APIs, webhooks and connections to the payment, CRM, ERP and messaging systems you already pay for.

  • Mobile apps

    iOS and Android apps from a shared React Native codebase when your users need offline use, push notifications or the camera.

  • Modernization of existing systems

    Moving a legacy app to a current stack one module at a time, so the business keeps running while the old system is retired.

Process

How a build runs

Short iterations, a demo every week and nothing you have to take on trust.

See how we work

  1. Discovery call

    A free call about your goals, users, constraints and deadline. You receive a short written summary and our view on whether we are the right team.

  2. Scope and quote

    We break the work into features, call out the risky parts and agree on what the first release includes. You receive a written scope, a timeline and a fixed-scope quote.

  3. Build in weekly iterations

    We build in one-week cycles and show working software at the end of each one. You receive a demo, a staging link and a short progress note every week.

  4. Launch

    We set up production hosting, monitoring and backups, then release. You receive a live product, admin access to every account and handover documentation.

  5. Support and next steps

    We fix launch issues and help you plan the next release based on what real users do. You receive bug fixes for 30 days after launch and a prioritized list for the next phase.

Custom software development FAQ

How much does custom software development cost?

It depends on the number of features, integrations and user roles. After a free discovery call we write a scope and give you a fixed-scope quote for the first release, so you know the cost before any work starts.

How long does a typical project take?

A focused first release usually fits in 6 to 12 weeks. Larger platforms are split into releases so you have something live early. The written scope includes a week-by-week plan.

Who owns the code?

You do. The code lives in your repository from the first commit, and all code and IP transfer to you once the invoices for that work are paid.

Can you work on our existing codebase?

Yes. We start with a short code review to understand the structure, tests and deployment, then agree on what to fix first. We follow your conventions unless they are causing the problems you hired us for.

Do you sign an NDA?

Yes. We sign your NDA, or send ours, before you share anything confidential about the product.

What happens after launch?

We fix launch bugs for 30 days at no extra cost. After that you can keep us on for new features and maintenance, or hand the project to your own team using our documentation.
