Custom software & app development
SaaS and MVP development, AI-built app completion, white label development for agencies, and business integrations, guided by experienced engineers from design and testing to launch.
Software & Apps
What we build
New products, existing apps and complex systems, for startups and established businesses alike. Pick the one closest to yours.
What we do
Design, engineering, QA and DevOps in one team, so nothing falls between vendors. AI speeds up every discipline; experienced specialists direct the work, check the results and stay accountable for them.
Web apps, SaaS platforms, mobile apps, startup MVPs, business systems, APIs, e-commerce and modernization, plus AI features and agents when your product needs them. Coding agents speed up implementation; engineers own architecture, reviews and technical decisions.
Test strategy, automation, exploratory testing, AI-system evaluation and release readiness, for software we build or software you already run. AI drafts tests and helps investigate defects; QA specialists test against requirements and make the release call.
Deployment pipelines, infrastructure, monitoring, backup and recovery, private model hosting and ongoing operations. AI assists with infrastructure code and diagnostics; DevOps engineers review configuration and approve production changes.
Discovery, research, user journeys, prototypes, interface design, design systems and usability improvement. AI speeds up synthesis of the research you permit and design exploration; designers own usability, accessibility and validation.
Every project
AI tools speed up design, engineering, QA and operations, whatever you're building. Your product doesn't need an AI feature to benefit.
Compare development packagesWhen your product needs it
AI agents, LLM features, chatbots and models inside your product, with permissions, evaluation and human oversight designed in. A separate service.

Explore our software development, QA, DevOps, UI/UX and integration services, with two AI delivery options. These figures describe the current service catalogue.
AI delivery options
Both packages deliver the same expert-led, AI-assisted engineering. They differ in where AI tools process your code and project context while we build, and in what has to be set up and run.
Software delivery with suitable privately hosted models, inside a processing environment we agree with you. It's an engineering engagement, not GPU rental: we select and evaluate models, set up development agents and their permissions, and deliver with the same expert design, QA and release control.
Best fit
Policies that keep source code, prompts and research inside a boundary you control.
Expert-led delivery using Claude Code and/or OpenAI Codex with approved cloud-model configurations. You buy our engineering capability, not a resold AI subscription.
Best fit
Teams that can approve commercial AI coding tools and want an AI-first workflow without hosting models.

How we build
Our AI engineering harness connects leading coding agents (Claude Code, OpenAI Codex or privately hosted models) to your project's context, tools and tests. Specialists scope every task, review every change and decide what ships.
AI speeds up synthesis of permitted research, exploration and prototyping.
Designers own usability, accessibility, consistency and validation with real users.
Coding agents implement, refactor and draft tests and documentation.
Engineers own the architecture, review changes and make the technical decisions.
AI drafts test cases, analyzes coverage and helps investigate defects.
QA specialists test against requirements and decide whether a release is ready.
AI helps write infrastructure code, read logs and diagnose issues.
DevOps engineers review configuration and approve every production change.
Ways to work with us
Every engagement has its own scope. Choose where you are, and the enquiry form opens with it selected.
Support hours, response commitments, responsibilities and exclusions are agreed for each engagement.
How We Work
QA, security and DevOps start in the first week and continue through every phase. They're not a final checkpoint.
Illustrative delivery plan
ExampleGo-liveThroughout delivery
An example plan. Every project is scoped individually.
We clarify goals, users and constraints, then map the key journeys and prototype them. AI speeds up exploration; experienced designers decide what serves your users and your business.
Engineers set the architecture, data flows and integrations, and we agree which AI tools may be used, where processing happens and what they can access. QA plans tests from the requirements.
Engineers break the work into scoped tasks and coordinate coding agents to implement, refactor and draft tests. Changes are reviewed before they're merged, and you see progress in regular demos.
QA specialists test against requirements and real user behavior, with AI helping draft tests and investigate defects, plus risk-based security and performance reviews. Issues are fixed before release, not after.
DevOps manages controlled releases with monitoring, recovery plans and documentation, using AI to help diagnose issues. After launch, we keep improving the product under an agreed support scope.

FAQ
We build software of every kind: startup MVPs, SaaS platforms, web and mobile apps, business and enterprise systems, e-commerce and integrations, plus AI features when a product needs them. Our engineers, designers, QA and DevOps specialists work with leading AI coding agents, so delivery moves faster while people stay in charge of every decision. SEO and digital growth remain available as a secondary service.
Yes. We help you decide what the first version must include, then design it, build it for the web, iOS or Android, test it and launch it. AI coding agents keep the build fast; engineers make the architecture decisions so the product can grow beyond its first version, and we can keep improving it after launch.
No. We use AI to build software, and we build AI into software only when the product needs it; those are different services. A web app, SaaS platform or internal tool without AI features still benefits from AI-assisted engineering, QA and operations.
Our team is. Engineers own the architecture and review changes before they're merged, QA specialists decide whether a release is ready, DevOps engineers approve production changes and designers own the experience. AI speeds up the work; it doesn't make those decisions.
Private / Local AI Engineering uses privately hosted models inside infrastructure you control or an agreed isolated environment. Claude Code / OpenAI Codex Engineering uses Claude Code and/or OpenAI Codex with cloud settings your organization approves, with no model infrastructure to run. Both follow the same engineering, design, QA and release standards.
Yes. Each capability can be engaged on its own: independent QA for software built by any team, DevOps and infrastructure work including ongoing operations, or UI/UX design without development. Scope and deliverables are agreed per engagement.
We can stay on under a scoped support engagement covering releases, maintenance, regression testing, infrastructure and monitoring, and AI agent or model operations where relevant. Support hours, response commitments and exclusions are agreed up front.
Yes. We start with a scoped paid assessment of the code, data, authentication, integrations and deployment. You receive findings and a completion plan before committing to the full work. A rewrite is only proposed when the evidence supports it.
