Custom software development for complex, business-critical systems

Off-the-shelf software works until it doesn't. When your business needs something that fits exactly how you operate, scales with you, and doesn't force you to work around someone else's limitations, that's when custom software makes sense.

We build it from the ground up, with the technical depth to get it right.

Why off-the-shelf isn't always the answer

Standard software products are built for the average case. They're fine when your needs are generic, but the moment your processes, data, compliance requirements, or user needs diverge from the mainstream, you start hitting walls. Workarounds pile up. Integrations break. Your team spends more time fighting the tool than using it.

Custom software removes that friction. It's built around your business rather than the other way around. You own it, you control it, and it can evolve as your needs change without waiting for a vendor's product roadmap to catch up.

That said, custom isn't always the right answer either. If an existing product does what you need, we'll tell you. Building something bespoke is a significant investment and it should only happen when the value justifies it – when the software is central to how your business operates or competes, not when a SaaS subscription would do the job.

What custom software development looks like with us

We handle the full lifecycle – from understanding the problem through to a live, supported product. No separate teams for design, architecture, and development creating gaps and handoff problems. The same people who understand your business goals are the ones writing the code.

  • Full-stack web applications

    Most of what we build are web applications – sophisticated, interactive systems that users access through a browser. Not brochure websites, but tools people use to do their jobs, manage operations, serve their own customers, or make decisions based on real-time data.

    We work across the full stack, handling everything from the user interface through to the server-side logic, database design, and infrastructure. Having one team responsible for the whole system means fewer integration problems, faster debugging, and a product that feels cohesive rather than stitched together from separate workstreams.

  • Complex business systems

    Some projects involve genuine complexity – multiple user roles with different permissions, intricate business logic, regulatory compliance requirements, large data volumes, or integration with a web of existing systems. These are the projects where experience matters most, because the hard part isn't writing the code. It's understanding the problem well enough to design a system that handles every edge case without becoming unmanageable.

    We've built systems across industries including finance, research, and ecommerce, each with their own particular demands around data handling, security, and reliability. That breadth of experience means we're rarely encountering a type of problem for the first time.

  • API design & integration

    Modern software almost never exists in isolation. Your application will need to talk to other systems – payment providers, CRMs, analytics platforms, internal tools, third-party data sources. We design clean, well-documented APIs and build reliable integrations that handle the real-world messiness of external systems: rate limits, downtime, inconsistent data formats, and poor documentation.

    When we're building an API for others to consume, we design it for the developers who'll be working with it. Clear endpoints, consistent conventions, proper error handling, and documentation that actually helps. An API that's painful to use creates problems for everyone downstream.

  • AI-enhanced software

    AI is most useful when it's embedded within a larger system, not bolted on as a gimmick. We build software with AI capabilities where they actually improve the product – things like intelligent search over large document sets, automated classification and routing, natural language interfaces to complex data, or decision support tools that surface insights humans would miss.

    We work with frontier model APIs from providers like OpenAI and Anthropic, and build RAG systems that let AI work with your own data accurately and reliably. The key is knowing where AI adds value and where traditional software engineering is the better solution. We're comfortable making that call.

  • Security-first development

    Security isn't a layer we add before launch. It's built into how we write code, design systems, and handle data from day one. Authentication, authorisation, encryption, input validation, secure API design – these are foundational decisions, not final checks.

    If your project handles personal data, financial information, or anything subject to regulatory scrutiny, the architecture and code are designed with that in mind from the start. We follow established security practices because retrofitting security onto an insecure system is one of the most expensive and unreliable things you can do in software development.

  • Performance at scale

    Software that works with ten users but falls over with ten thousand is software that wasn't built properly. We design and build systems that perform under real-world conditions – handling concurrent users, large datasets, and traffic spikes without degrading.

    This means making informed decisions about database design, caching, query optimisation, infrastructure scaling, and frontend performance from the start. Not over-engineering for imaginary scale, but making sure the foundations are solid enough that growth doesn't require a rebuild.
