Modernise your software with AI.

We are a UK software agency that adds AI to the systems businesses actually run: legacy platforms, live products, real data and permissions. React and Next.js where they fit, cloud-native underneath, and honest advice about where AI earns its place and where it does not.

AI systems
Cloud modernisation
React & Next.js

The team at Maven went above and beyond with our project, always finding cost effective and high quality solutions, no matter how tricky the task was.

Services - AI, modernisation, and the senior delivery to ship both.

Our lead work is adding AI to software businesses actually run: agents, RAG assistants, and LLM features in real systems. Twenty-two years modernising legacy and cloud platforms is what lets us do it safely, and senior React and Next.js delivery is how it ships.

AI integration & agents

RAG assistants, autonomous AI agents, and LLM features wired into your real data, permissions, and operational systems. Not demos: software you can put in production.

AI-powered modernisation

Legacy React, PHP, ColdFusion, and API estates moved carefully onto faster, safer, AI-ready cloud foundations, with measurable risk reduction.

Product engineering

Senior React and Next.js delivery across discovery, UX, frontend, backend, mobile, QA, and launch. It is the proof we can ship the AI work too.

  • AI Integration & Development. We build production-ready AI solutions that deliver real business value: RAG-powered chatbots, autonomous AI agents, and LLM integrations that make your existing software smarter. From strategy through deployment on AWS, we handle the full AI lifecycle. Learn more about our AI services.
  • AI-powered Legacy Modernisation. We move legacy platforms onto modern, AI-ready foundations incrementally, without a big-bang rewrite: ColdFusion, PHP, ageing React, and legacy APIs onto React, Next.js, and AWS while the business keeps running. See how we modernise legacy software.
  • ColdFusion Modernisation. One of the few UK agencies still supporting ColdFusion, and the one that modernises it. Maintenance, Adobe CF and Lucee upgrades, security hardening, and incremental, AI-ready migration off CFML, backed by 22 years of experience. See our ColdFusion services.
  • Legacy API → AWS API Gateway (fixed price). Your legacy REST API rebuilt on AWS API Gateway and Lambda in six weeks, for a fixed £15,000. Near-zero downtime, full infrastructure as code, CI/CD, monitoring, and a documented handover. See the migration scope.
  • React & Next.js Development. We build greenfield React apps and modernise legacy codebases, deployed on AWS serverless with fully automated CI/CD pipelines. Whether you are starting fresh or migrating from jQuery, Angular, or PHP, we handle the full journey from code to cloud. Learn more about our React and Next.js work.
  • Web & Mobile Development. We deliver exceptional digital experiences across web and mobile platforms, building responsive websites, PWAs, and native apps with React Native and Flutter. From concept to deployment, we create tailored solutions that drive real results. Learn more about web & mobile.
  • React Codebase Audit (fixed price). Need an independent senior opinion before committing to a big decision? Our £2,500, five-day audit gives you a prioritised remediation plan covering architecture, performance, accessibility, security, and CI/CD. See what the audit covers.
  • E-commerce. We build online stores that convert, specialising in Shopify, Magento, and headless commerce. Every store is optimised for speed, mobile, and search engines. Learn more about e-commerce.
