Strategy

Real digital impact starts by asking the right questions. And it certainly doesn't end with heavy reports or endless PowerPoint decks. We believe in working concepts, with the user experience as your primary growth engine. Together with your team, we strip the challenge down to its core. By aligning business goals, user needs, and technical feasibility, we deliver a sharp product vision and a clear roadmap. Rather than chasing isolated features, we make strategic choices that give you a solid foundation to build on and accelerate.

"This project shows that with the right partners, you can truly transform healthcare."

Tjebbe Tauber, CEO HeartEye

Validation

Major investments shouldn't be made on assumptions. Through rapid prototyping and direct user testing, we validate hypotheses immediately in the real world. With our Jumpstart methodology, we go from a rough idea to a tangible, testable product in just a few weeks. This allows us to quickly uncover whether a concept delivers genuine value for both your users and your business case. It drastically reduces execution risk, prevents costly development waste, and gives you the data-backed confidence to move forward decisively.

"We learned that within one week you can really get more done than you think if you take on the experimentation mindset."

Leny van Eeden, product owner self-service kiosk KLM

Design

Making complex applications surprisingly simple and engaging: for us, software development is above all interaction engineering. Together with our sister agency Fabrique, we create digital interfaces that feel intuitive, meet the highest accessibility standards (WCAG), and bring genuine joy to users. By combining UX, brand identity, and engineering right from day one, we craft scalable digital experiences that fit seamlessly into everyday life. The result: inclusive products users love that elevate your brand.

"For many years, Q42 has been a trusted partner in building user-friendly, future-proof digital solutions."

Ellen Bakema, product owner at Museumvereniging

Development

From lightning-fast apps and accessible websites to smart IoT products like Philips Hue: we build software your organisation can rely on for years to come. No black-box complexity, but total transparency, control, and agility. We seamlessly integrate complex backend systems into a single, reliable engine that grows effortlessly alongside your ambitions. The result: maximum business continuity, lower maintenance costs, and the freedom to keep innovating at speed.

"Q42 handled complexity without losing sight of what mattered most: a reliable, enjoyable experience for players."

Sara Quejido, product owner JUMBO

Innovation

Accelerating innovation without getting bogged down in sluggish processes: by pairing technical craftsmanship with emerging technologies (with a strong focus on AI) we navigate you through complex technical challenges. We validate ideas in days rather than months using our Jumpstart methodology. For us, innovation isn't a theoretical framework; it's a rapid cycle of hands-on experimentation, prototyping, and real-world testing. This allows you to transform technological possibilities directly into systematic innovation and a distinct competitive edge.

"What I love about this tool is how it helps us become more sustainable, faster and better."

Christian Alferink, product owner BAM

Replatforming

Sluggish legacy systems hamper your agility and drain your budget. We help you modernise step-by-step towards a flexible, modular architecture without ever closing for business. No high-risk ‘big bang’, but a controlled dismantling of the legacy monolith. Through smart phasing and continuous delivery, you maintain 100% business continuity. The result: a future-proof platform that restores your innovation speed and dramatically reduces maintenance costs.

"Q42 venture far beyond their own responsibility to make your product as impactful as possible, making their partnership invaluable."

Thomas Steffens, CEO Primephonic (now Apple Music Classical)

Scaling

From international expansion to extreme traffic spikes such as Wie is de Mol?: you want absolute certainty that your platform runs flawlessly. With well-thought-out architecture and 24/7 support, we give your organisation complete peace of mind. Our proactive monitoring resolves bottlenecks before a user even notices. With this focus on operational excellence, we guarantee maximum uptime and peak performance. This means you can rely day and night on a robust platform that scales effortlessly alongside your ambitions.

"Thanks to Q42, we’ve scaled to a million users over the past two seasons without any of the usual performance issues."

Finus Tromp, Head of Interactive Media at AVROTROS

Capability building

Our ambition isn't to remain indispensable, but to make your organisation sustainably stronger. We work closely as one integrated team. By building together, we elevate the technical and product maturity of your own developers, designers, and product owners. Through on-the-job coaching, workshops, and best practices, we embed knowledge directly within your organisation. That way, you can continue to innovate independently and at a high level long after handover.

"The app has really great options and will be a huge advance for dealers and farmers."

Eddie Perdok, CEO Kramp
