Walk on the cutting-edge

We explore real-world applications of emerging digital technologies through a user-centered, prototype-driven approach.

Web, 2005→

We have vast experience with interactive media solutions, social networks, marketplaces, IoT dashboards and other complex, browser-based applications.

Mobile, 2005→

We have been involved in mobile since before the iPhone was a thing, working on messaging and interactive content, later moving into native and cross-platform mobile application development.

VR/AR/MR, 2009→

We have long explored the potentials of immersive technologies for input and output of information. Furthermore, we are a development partner for Microsoft’s HoloLens technology.

Cloud, 2010→

We create and maintain highly-scalable applications, using containerised micro-services and custom APIs in public and private clouds. We are enthusiasts and practitioners of DevOps.

IoT, 2010→

Our longstanding relationship with telco IT providers has kept us at the forefront of device connectivity, developing core technologies.

Blockchain, 2010→

Looking beyond the cryptocurrency hype, we are exploring use cases and business models for decentralised applications and their underlying protocols.

Work with venture-level talent

We attract and nurture some of the most gifted craftsmen in the industry, many of whom launched their own ventures and decided to stay with us as advisors.

Don’t feel locked-in

We work on products, not projects. This entails long-term commitments which might be intimidating and that’s understandable. Don’t worry, we have you covered all the way.

Transparent pricing

It’s simple, really. You get a dedicated team; each specialist has a day rate. Our accounting is transparent and we reconcile the books with you on a quarterly basis.


We are committed to you through the entire product lifecycle. However, you are free to insource work on the product at any point and we’ll help you make the transition.


Insourcing can be a challenge for your HR. We can organise specialists training programs to secure a successful product handover or invite you to attend our related community events.

Let’s push the envelope in your industry.
