Getting platforms to actually talk to each other is no small feat. Between legacy systems, cloud apps, and whatever else your business relies on, integration can get messy fast. That’s where platform integration companies come in. These are the folks who know how to connect the dots behind the scenes so your tools and teams work in sync without constantly switching tabs or chasing data across platforms.
In this article, we’re diving into some of the companies in the UK that are doing this well. Whether you’re trying to streamline operations, automate repetitive tasks, or just get your systems to stop arguing with each other, these teams know how to make the connections that keep everything running smoothly.
1. A-listware
At A-listware, platform integration is something we deal with regularly, especially when clients need to connect cloud platforms, legacy tools, and custom software into a working whole. We know it’s not just about plugging systems together and calling it done. It’s about making sure data flows where it needs to go, teams don’t lose time dealing with manual tasks, and the whole setup stays stable as things evolve. Our approach mixes dedicated engineering teams with consulting support so we’re not just building things, we’re helping shape how those systems talk to each other and stay aligned with the bigger business goals.
We’ve worked with startups, enterprises, and everything in between in the UK. That flexibility shows in how we structure projects, whether it’s a proof-of-concept, a custom integration layer, or a fully managed delivery pipeline across tools and departments. We don’t chase buzzwords, and we’re not trying to sell shiny platforms. We just make sure the ones you’ve already got can work together without tripping over each other. And when something needs custom code or a smarter connection, we’re ready for that too.

Conclusion
Wrapping up, it’s clear that platform integration isn’t a one-size-fits-all job. Some businesses are trying to link decades-old systems with new cloud tools, while others just need a way to stop bouncing between disconnected apps. The companies in this article show how differently that challenge can be approached. Whether it’s through full-service consultancies, tight industry-specific setups, or smaller teams focused on day-to-day workflow fixes, there’s no shortage of ways to get systems talking to each other more smoothly.
What stands out isn’t just the tech they use, but how they handle the messiness behind it. Real-world integration is less about perfect diagrams and more about figuring out what works without grinding everything to a halt. That might mean building around what’s already in place, adding smarter automation, or finally getting two platforms to sync without someone babysitting it. In the end, good integration should feel invisible. It just works in the background, keeping things flowing while teams focus on the actual work.
