  • User Experience is not just about functionality to us. It is the foundation for everything we do here at Heisenbug®. The UX/UI and web design projects we undertake, ranging from building a new product to re-designing an existing mobile app, website, or enterprise software. We do anything and everything that is needed to make successful digital products: user research, product strategy, user interface/experience design, usability testing, prototyping, web design, and development. We are an agency that believes a great website must effectively convert visitors into customers, all the while providing an enjoyable online experience true to the brand. Good user experience and user interface design for a digital product or site lead to higher conversion rates. Unlike other agencies, we have UX/UI designers working alongside web developers in all our projects.
  • We get that question all the time. There are a ton of competent UX agencies just in Norway, or even more around the world. It is difficult to stand out when the standards are this high. So, how do we differentiate ourselves? Heisenbug® designs and engineers engaging digital products that people love to use. We work seamlessly with our clients to define core problems, design, and develop user experiences across all platforms and brands' touchpoints; with UX always staying at the top of our list.
  • We are recognized for creating marketing websites that achieve the goals of our clients, merging brand narratives and unique web design with today's latest and greatest web technologies. Heisenbug® is perfectly equipped to provide websites to tech startups, as opposed to other web design firms that mostly focus on web designs for traditional businesses. In short yes, we can. Come play with us.
  • Yes, we do. Above all else, we are a user experience and tech agency, and branding is integral to every UX/UI design project. We are positioning ourselves as a type of branding agency, focused on tech companies, digital products, and direct-to-consumer brands. Our branding capabilities include research, brand and digital strategy, logo design, visual identity, graphic design, motion design, style guide development, and web design, among others. However, oftentimes, our clients will give us a brand strategy, or even an entire package of visual identities. In those cases, we take the existing foundation of the brand as our starting point, and we do not simply apply it thoroughly to everything that we develop, but make sure that we expand and flesh out the brand while staying true to its roots.
  • Our rates are directly related to project scope, time frame, deliverables, and team composition. When the scope is not fixed or the project is highly dynamic, we prefer working on a Time & Materials basis, where you pay us based on time spent. However, the majority of our UX/UI engagements are fixed-price contracts. In that case, we give you an itemized proposal once we have learned as much about your project as we can. All estimates are calculated from an hourly rate and how many hours we believe the work should take. For time-and-materials commitment, we will build you a customized pricing sheet depending on your team composition. Please contact us to receive a quote.
  • As a design and tech agency in Norway, we work with startups all the time. What could be better than helping founders execute ideas that the world has never seen before? We love a dynamic environment, which challenges our skills and processes. The ultimate accomplishment for us is seeing our start-up clients grow and rule the world. We have a special discounted rate for startups that we believe in.
  • Our UI/UX design process is based on Human-centered design which we call the Common Sense Kingdom. This allows us to be flexible, adapting to almost any project type and collaboration model. Your business is unique, and so is your user.
  • If you are looking for a UX/UI Design Agency, please first send us an email with a brief outline of your project or RFI/RFP. During our initial meetings, we will ask many questions about your project's goals, audience, budget, timeline, and other important details. We may sign an NDA if needed, but we always consider all conversations with clients to be confidential. While many UX/UI design agencies work only at an hourly rate, we make sure we can accurately estimate a project's costs before starting. Based on your requirements, we will include an in-depth description of our UX/UI methodology, the stages of the project, tasks, deliverables, the design team composition, and related case studies.
  • Yes – and it’s our preferred approach. A headless CMS separates the content layer from the presentation layer. That means your content is managed in one place, but can be delivered anywhere – websites, apps, screens, even kiosks. It gives you more flexibility, better performance and stronger security compared to traditional monolithic platforms. We typically pair headless CMS with modern front-end frameworks like React (Next.js) and GraphQL to create lightning-fast, scalable solutions. The result? Faster load times, better SEO, smoother editor experience and easier integrations with other systems. We work with a range of headless CMS platforms, including Payload, Sanity, and Strapi, and tailor the setup based on your needs and team preferences. Still using a traditional CMS like WordPress, Magento or Webflow? No problem. We also build and maintain solutions on those platforms when it makes sense. Not sure what you need? Let’s talk – we’ll help you make the right call.
  • Heisenbug CAT™ (Communication Application Toolkit) is our innovative solution that facilitates integrated communications across a multitude of systems through standardized communication protocols and APIs.

These kiosks, along with other digital touchpoints, are designed to maximize usability and minimize the need for manual intervention. Our expertise in developing complex, user-oriented solutions demonstrates our capacity to support various industries, including the travel sector.
  • At Heisenbug®, we have extensive experience in creating seamless integrations with a variety of business systems such as ERP/CRM, payment solutions (PSP), and booking platforms (PMS). Our philosophy is simple: If there's an API, we can connect to it. We leverage this flexibility to create integrated solutions that improve efficiency and user experience. Additionally, we are proud to be partners with leading companies such as Assa Abloy, Nets, Adyen, Desko, and VisBook. This gives us unique access to the latest technologies and services, enabling us to provide advanced and robust integrations for our clients.

  • Yes, we develop applications for Apple (iOS), Google (Android), and Windows platforms. Our team has extensive experience in creating cross-platform solutions that cater to the unique requirements of each operating system, ensuring a seamless user experience across devices.
  • Sanity is a modern and widely used headless CMS, known for its flexibility and clean editor experience. We’ve built several projects with Sanity and know it well – but these days, we often recommend Payload. Payload is a self-hosted CMS built in TypeScript that gives us full control over content structure, access control and custom logic. It’s fast, flexible and ideal for projects where we want freedom without unnecessary complexity. That said – we’re not dogmatic. We work with the CMS our clients prefer, as long as it’s headless. Whether it’s Sanity, Payload or another modern platform, we’ll make sure the setup is solid and future-proof. Here’s why we love working with Payload: 1. TypeScript-first – End-to-end typing means fewer bugs and a better developer experience. 2. Self-hosted – Full control over hosting, data and integrations. 3. Built-in auth and access control – Easy to set up, fully customizable. 4. Flexible content modeling – Structure your content exactly the way you want it. 5. Powerful API – REST and GraphQL support, rich query options and upload handling. 6. Feels like a real app – Payload works more like a full application framework than a traditional CMS. In short: You choose the CMS – we make it work.

  • There are two types of businesses: those that have already experienced a hacking attack, and those that haven't yet. The question isn't "if" it will happen, but "when". In a world with rapidly evolving cyber threats, protecting your systems is essential. In Norway, there has been a significant increase in the number of businesses targeted by hackers, with consequences ranging from the loss of sensitive information to severe damage to reputation and finances. Our solution, Heisenbug WHAT™, is at the forefront of addressing this challenge. The service is led by one of Norway's leading white hat hackers, who triumphed in DnB's prestigious hacking competition in 2023. By utilizing ethical hacking, we thoroughly analyze your systems, simulate attacks, and identify potential vulnerabilities. Contact us to discuss how we can help you enhance your digital security.
  • We take great pride in our high credit rating, AAA, awarded through Dun & Bradstreet’s credit rating system – the world’s oldest and most renowned.
