Logo: Zenjoy is an AI-first digital product studio based in Leuven. We build meaningful digital products, websites, and mobile applications.

Organisations with existing software

When the software stops, the whole operation stops. Then you need more than a web agency.

Medtech, industrial SMEs, labs, spin-offs and hardware with a digital layer. Commercial companies are welcome. For brochure websites, we refer you elsewhere.

What does a product partner do for existing software?

Zenjoy takes over existing custom software, maintains it and develops it further: web applications, platforms, apps and internal tools built by another team or a developer who has since left. We start by examining the code, infrastructure, documentation and access. Then we decide what can stay, what has to change and who takes on the management. That gives a platform, app or internal tool a realistic way forward.

Products the whole organisation runs on

The product exists, but there is no team to build it further.

The original developer is gone.

Code, hosting, app stores and that one scheduled task: someone has to dare to touch it.

We have hardware / a lab / a process. The software is the afterthought.

Once customers are using it, the software is no longer a side issue but part of the product.

Our in-house team can build features, but can’t manage the whole product.

Not every organisation has a full product team for UX, mobile, data and releases. We complement the team or take on a clearly defined part.

We don’t want to get stuck again.

We agree on which documentation, access and knowledge transfer are needed to manage the product and hand it over later.

Take over, improve and keep managing

Take over

We examine the code, dependencies, hosting and accounts. Then we plan a handover with clear responsibilities and a first list of risks and priorities.

Modernise

Develop existing software further with new integrations, a mobile app or AI on your own data. As with Bitos, we don’t replace everything, only the part that is stuck.

Run

Care or a fixed amount of product capacity per month. Priorities can change without a new quote for every ticket. Care

We work with founders, CTOs, product owners and operational teams. Up front, we set out agreements on code, licences, accounts, documentation and handover.

From a stalled website to a digital operation that can grow again

Content types, steel analyses, vacancies and training courses. Not a new visual identity for its own sake, but a product that can grow with the business again.

Bitos

Quality control, rewritten

A new visual identity and a thorough rework of the application. Not a shop window, but an integrated product for a company where the tool itself is the service.

Belgian technology with international reach

We don’t only work for non-profits, but also for international technology companies. A long-term digital challenge is a good fit for us when it calls for real product work.

Lees de case

Ectosense shows the link between hardware and software. The patient-facing product question is covered on Digital health.

First we check whether we can responsibly take over the product.

We start with a focused exploration of the code, infrastructure, accounts and documentation. You get a clear view of the risks, whether a handover is feasible and a first plan for what comes next. Looking for a new product? Web platforms.

Questions we often get

Yes, if the challenge is a technically interesting digital product for the long term. Not for high-volume websites or campaigns.

Yes. We can form the entire product team or take on a clearly defined part, such as mobile, platform or Care. No loose profiles without product responsibility.

Ownership of custom code and access to repositories and accounts are set out in the contract. Existing software and external components may have their own licences. We map those out when we take over, together with what is needed for a later handover.

Sometimes. We first look at what is already there. If the idea is proven, we work out what is still needed for real users, real data and sustainable maintenance. We don’t promise a rescue operation without understanding the product.

The price of Care and further development depends on the technology and the pace. Once the formulas are settled, we will publish clear indicative prices. Platform & App Care

Does your operation run on software that can’t afford to stop?

Has the original builder left, has further development stalled, or does your team need reinforcement? Describe the situation and we’ll look at a feasible handover or collaboration.
