Web App & Website Development
Fast, accessible websites and web applications, from marketing sites to customer portals, dashboards and online shops.
Web App Development for UK & international businesses
Your website is often the first and last thing a customer sees before they buy. It needs to load quickly on a phone, rank in search, explain your offer clearly and make the next step obvious. Web applications have a harder job: they have to handle accounts, data and payments reliably, every day.
Maetheon Ltd builds both. We design and develop business websites, web apps, client portals, dashboards and e-commerce stores for companies in the UK, the US, Canada and Australia. We are a UK-registered company with a remote delivery team, so you get a UK contract, clear communication and a single accountable point of contact.
Search visibility is built in, not added at the end. We run SEO for our own network of 17 giveaway and comment-picker tools, each with its own blog, so technical SEO, page speed and structured data are part of every build.

Websites that have to earn their traffic
Our own products depend on search. Each of our 17 picker tools runs on its own domain, with a tool page and a blog, and has to be fast, crawlable and clear enough to convert visitors into sign-ups. The same standards go into every client website we build.
