Our Services In A Nutshell

Inspire & Convert

We produce inspiring, conversion-optimised website designs for a clean, lightning-fast and enriching experience across all devices. Web builds have been our bread and butter since 2005, and we continue to win awards and innovate with custom solutions, eCommerce shops and web apps.

We have an exceptionally talented, UK based in-house team of developers who focus on providing the best, cost-effective solution whether it’s a custom build or using a framework.

Meet our team

Selesti digested our complex brief and produced a modern website that our customers enjoy using. We love to work with the entire team and their great ideas.

- Lucy Hearne, Hitachi Digital Media


We’ll find the right combination of functionality and user experience to meet your organisation’s needs, and those of your customers. We’ve launched hundreds of eCommerce websites, with Magento, Shopify and WooCommerce. We also create custom solutions, whether you’re looking to sell a handful of t-shirts to tens of thousands of products daily B2B.

Our Digital Marketing team will ensure your most profitable products appear for relevant search terms, driving return on investment with UX optimisation and invaluable content audits. We’re aiming to drive traffic straight to the product detail pages, not a homepage several clicks away from a purchase.

Mobile search has overtaken desktop search, and thanks to Google’s ‘mobilegeddon’ update, having a mobile-friendly site is now an essential part of maximising organic traffic and providing a positive user experience.

Our web builds are designed to look and work beautifully across all devices, ensuring your mobile visitors have the same great experience as your desktop visitors and can complete a transaction in a couple of clicks with no pinching and zooming.

Content Management Systems

Complex CMS requirements are often best suited to a bespoke build using our CMS HQ framework. This provides the agility for many integrations and caters to specialist features and automating existing manual processes.

We also love open-source platforms such as WordPress and Drupal; it’s about finding what will maximise the potential of your brief and the return on investment from your budget.

API Platform Development and Integration

We’ve built custom integrations and plugins for many platforms such as: Magento, Sage Accounts, SalesForce, HubSpot, Redmine, Slack, Google Drive, Strava, Barclays EDPQ and Experian to name just a few. Integrating your CRM with your bespoke ERP or your Xero inventory with one of your supplier’s systems is something we relish.

We’ve created bespoke APIs linking up clients’ internal systems with the new online platforms we’ve built, imported data on a scheduled basis and that can enable lead generation websites to create quotes on the fly.

Web Applications and SPAs

The more niche your requirements and market you work in, the more we roll our sleeves up and enjoy designing an application that will help your business run more smoothly.

Our team have won awards for social media Single Page Applications (SPAs), please see 7billionIdeas Case Study and produced a web application called PathFinder for an energy broker which automated a massive number of manual processes, speeding up their in-house procedures, increasing profitability and reducing admin.

Performance and UI/UX Optimisations

The expanse of platforms, development languages and hosting solutions can be mind-boggling if you’re just looking to get your digital idea off the ground.

To us, it’s about more than just delivering web design and build — we want to ensure you're confident with your choice, so we go further by offering training and digital marketing advice too.

We look at your goals, targets and your customers’ needs, and determine the best way to optimise the user experience so that you increase goals and conversions — whatever yours them into a sale, a lead or ways to measure a reduction in basket abandonment, for example.

Rapid Prototyping

Key to realising a product idea is to see it working as quickly as possible. Using proven lean UX techniques and our investment in prototyping tools, we partner with you on a proof of concept before nailing down the final scope, saving lots of wasted hours.

We work using Agile or Waterfall project management processes based on the project and deadline and spend more time on UX and production than being bogged down in scope during those important, early stages.
