Boost time to market

Boost your time to market

We have bundled our years of experience in software development into our Silicon Low Code platform. With Silicon we develop high-quality online software up to 3 times faster than conventional. We call that SMART development, a combination of software generation, open source and standard components. Silicon is a low code framework that can compete with the competition and offers many advantages. The most important one is reducing the time to market significantly. Moreover you will be able to quickly adapt to feedback and create new business opportunities.

Together we determine the requirements of your new application. Using interaction design and prototyping, the requirements are translated into easy to understand functionalities and screens. We then generate an online application with the Silicon Low Code platform containing tons of functionality out of the box.

The application is then expanded in short sprints so new, perfectly fitting and user-friendly functionality is immediately delivered and available for end users. To ensure the quality of our applications, we use modern methods such as automated testing and code reviews.

IntegratE your processes

System integration offers the possibility to link applications together. Making it possible for your clients to use straight through processing. The advantage of system integration and links is clear: data is handled automatically and error-free which saves a lot of annoying manual work and prevents many frustrations for customers and employees. Existing applications provided with a new modern interface, will last for a long time.

Whether it is Exact, Peoplesoft, Payment systems, SharePoint, Office, Dynamics, Selligent CRM, Mailchimp, Dun & Bradstreet, Graydon, public web services, insurance systems, care packages, ERP packages or customized work, we have already linked it or made it accessible once before. We link everything to everything, no challenge is too big for us.
