Trone | Web & App development

Verified

Web, app, and AI development

Websites, apps, web applications, web integrations, or AI automation that perfectly align with your wishes and goals.

Creating a beautiful website or app is one thing, but truly achieving the desired result is a challenge in itself. Trone Software helps you develop your goals and ideas into a well-functioning digital product that optimizes your business processes.

Our approach:

- Analysis: Together with you, we discover your goals, opportunities, wishes, and challenges, and develop a strategy.

- Design: Once we have a clear understanding of what needs to be done, we start with the design. We align the design with you, after which you can approve each part or provide feedback. As soon as the design is ready, we create a prototype that you can optionally share and test with others.

- Development: After approval and testing of the design and prototype, we start the development of the product. Progress is tracked on a status board that you always have insight into.

- Management and optimization: Once your application is live, we optimize it based on user feedback. We also perform maintenance as needed to ensure the application runs smoothly.

Why people choose us:

Communication:

We believe it's important that you stay informed about our work and progress. That's why we like to work with a status board where you can precisely follow what we are working on at any given moment.

Personal attention: We like to keep communication lines short. We are always directly reachable by phone (even outside office hours), and visiting us for a conversation is always possible.

Professionalism: We are not amateurs, but certified software engineers with years of experience in software development.

Value for money: Because we don't have large overhead costs and want to position ourselves in the market, our prices are relatively low. We are almost always cheaper than competitors of our caliber.

Think innovative

Our journey began at Inholland University of Applied Sciences, where we met as a team of students passionate about technology and problem-solving. With backgrounds in IT and a shared curiosity for how digital solutions could make life easier, we often found ourselves discussing real-world challenges and how software could solve them. It wasn’t long before the idea sparked: What if we started our own IT company—one that focused not on trends or hype, but on building useful, reliable tools that actually help businesses grow?

That idea became our mission. We founded our company with one goal in mind: to build valuable digital products that solve real business problems. From the start, we’ve focused on clarity, practicality, and purpose—cutting through the noise to deliver solutions that truly support teams and organizations. Our vision is simple: empower businesses to scale and thrive through technology. We believe digital tools should feel like an extension of your goals, not a barrier.

That means making digital less confusing, more helpful, and always aligned with your needs. We’re human-first, results-driven, and always collaborative. We listen before we build. We explain things clearly. We avoid shortcuts, respect your time, and treat every project like a partnership. With us, you’ll always know where things stand, and what’s coming next. This is our story—rooted in curiosity, grown through collaboration, and driven by a commitment to help businesses succeed with technology that works.
