Build your next product, fix one that is not working the way it should, or extend your engineering team with a trusted in-house software development company. Experienced designers and engineers, working your timezone, taking full ownership from the first conversation to the final launch.
From brief to a live, user-tested product in 6 to 8 weeks. We have built MVPs that founders have taken straight to investors and raised on. UX research, product design, and full-stack engineering, including AI-powered features where your product genuinely needs them. One team throughout.
We find what is actually broken, not just what looks broken. UX engineering services covering audit, redesign, and rebuild grounded in user research.
Dedicated designers and developers embedded in your team. Working your hours, on your codebase, to your roadmap. You direct the work. We handle everything else. Our team includes developers with hands-on AI and LLM integration experience. One-month trial to start.
C4 Logistics runs time-critical transport operations across the UK through three interconnected portals: an admin portal for its internal team, a supplier portal for carriers, and a customer portal for transport clients. All three had grown around the business over years rather than being designed for it, and every job, quote, and driver requirement passes through them daily.
Miigen, Library of Life, is a digital legacy platform for preserving and sharing life stories in text, images, and audio, so that milestones and reflections can be passed down across generations. Alongside the storytelling, the platform carries an advertising layer that lets individuals and businesses reach location-specific audiences. Craig came to us at the idea stage, with no existing product to build on.
Rebuilding a tennis club platform as a cloud MVP that secured its first investment round. 40Love set out to modernise how tennis clubs, tournament organisers, coaches, and players run their daily operations, replacing manual and fragmented processes with a single platform covering club management, tournaments, coaching, and payments. The business was already running on a locally installed FileMaker Pro system, which worked but could not scale, could not be reached from anywhere, and could not carry the product vision the founder had in mind.
Before you join the discovery call, we have already looked at your project, mapped the landscape, and formed a point of view. You do not arrive to an interview. You arrive to a conversation with a team that came prepared with observations, not a list of questions they could have emailed you the day before.
Most teams take a brief and start building. We push back on assumptions first. If something in your original thinking does not hold up under scrutiny, we say so before work begins, not halfway through the build when changing direction costs money.
Every user journey is mapped before a screen is designed. Every screen is validated before a line of code is written. The product is built for the person who has to use it every day, not the stakeholder who commissioned it.
You see real, testable software at the end of every sprint. Not a slide deck. Not a Figma file. Something you can open, click through, and respond to. If something needs to change, it changes before it compounds into a bigger problem.
Many clients move to a dedicated team on retainer after the initial engagement. The same people who built the product stay on it. No handoff, no re-briefing, no new team member who needs three weeks to get up to speed.
Most software companies open a code editor when they receive a brief. Exline opens an investigation. We look at the user, the market, and the problem before we propose a solution. That is why the products we ship work for the people who have to use them, not just the people who commissioned them.
We build AI-powered products, not AI demos. We have shipped a noise-logging app and a real estate operations engine that use AI to run real daily workflows. We integrate LLMs and automation where they genuinely improve the product for the people using it. When AI does not belong, we say so, so your budget goes on technology that serves your users.
The designer, developer, and project lead assigned to your project do not change. No handoffs to subcontractors. No freelancers introduced as full-time team members. No capability gaps discovered mid-project. The people who start your product are the ones who ship it.
Software development for startups in the UK often means choosing between speed and quality. Focused two-week sprints, a documented process, and a team that communicates daily means you get both. Working software at every milestone. A full proposal within five working days of your discovery call.
Not because every project was without challenge, but because when problems arose, we addressed them early, communicated honestly, and delivered something that worked for the people who had to use it.
That record is public. Fifteen reviews on Clutch. All verified. All 5.0. And it grows.
If you are evaluating software companies right now, you are probably doing it because a previous experience did not go the way it should have. We know what that costs, in budget, in time, and in the confidence of the people who were counting on the product to work. It is why we built Exline Labs the way we did.
