Digital Platform Development Agency | Custom Web Apps & Software

Your website rarely stands alone. We build integrated web apps and software to solve complex organisational challenges, while delivering seamless customer experiences.

Let’s talk

What is a Digital Platform?

Your digital platform is your entire digital footprint: your website, web apps, software, and the integrations that bring it together into a connected ecosystem. The aim is to build cohesive customer experiences and to streamline internal workflows.

End-to-End Digital Platforms

Reducing Friction Inside and Out

Create seamless digital platforms, removing the friction experienced by your customers and your team. This goes beyond website design into web app and software development, making sure everything’s connected, integrated, and working together as one.

Web App Development

Creating web apps that are intuitive to use, simplify user journeys, and are true to your brand. From customer portals and internal dashboards to subscription platforms and SaaS products, we create applications designed around real user workflows.

Software Development

Building custom software that solves real operational problems. We turn complex requirements into secure, scalable systems – from internal platforms to standalone products – always focused on solving the right problem with the right architecture.

Custom APIs & Integrations

Connecting systems that weren’t designed to work together. We build custom APIs and integration layers that get everything working in sync, connecting CRMs, automating data movement, and extending existing systems without disruption.

More on Custom APIs & Integrations

We have been working with Yellow Peach for over a year, and over that period they have become a trusted partner for our business and technology stack. They always take the time to explore the best solutions for the problems and challenges that we bring them before agreeing a path forward in a collaborative manner. Thank you!

Ed Maughan

Managing Director @ Group Accommodation

We worked closely with Yellow Peach and were impressed by their patience, professionalism, and attention to detail. As the project progressed, our trust in their team only grew. We’re absolutely delighted with the final results – thank you!

Jessica Urch

Marketing Manager @ Hidden Home Tech

We worked with Yellow Peach to build our Floresco website, and we’ve been delighted with the results. They’ve totally brought our brand to life, with a fresh, engaging and user-friendly WordPress site. They delivered exactly what we needed and made our creative ideas into tangible elements on the site. The team was super responsive and comms updates were great. Thanks so much to the team – highly recommended!

Sally Hunt

Co-Founder @ Floresco

Most reviews are a review of a company – this is a review of the people. From Day 1 Yellow Peach were great, in fact they challenged some of our assumptions which we not only appreciated but was one of the key reasons for choosing them. We are not techie, so we don’t know what we don’t know. Most of the tenders just blindly presented what we asked for, rather than interrogate our requirements. They worked seamlessly with our other partners and developed a first class website and application with dynamic APIs – totally recommend them and will use again.

Commonly Asked Platform Development Questions

Get in touch

How is platform development different from building a website?

Websites are just one part of your digital platform, albeit an important one. Platforms go further. They include applications, internal systems, data flows, and integrations that support how your business operates.
Do you build everything from scratch?

When it adds value, yes. We assess what you already have, then extend, integrate, or rebuild only where it adds value. The goal is a robust, scalable platform, not unnecessary complexity.
Can you integrate with our existing tools and systems?

Yes. We regularly integrate CRMs, marketing platforms, payment systems, ERPs, and third-party services. Where off-the-shelf integrations fall short (or don’t exist), we design custom APIs and integration layers to keep your data flowing.
Who is platform development best suited for?

Platform development is ideal for organisations that have outgrown simple websites, where disconnected tools, manual processes, or poor user experiences are slowing growth. If your digital estate feels fragmented, this approach brings cohesion and efficiency.
