Siller Portal Integrators GmbH has been formed in April 2009 as a result of the separation of the online division from Siller AG. Already since 1995 we set up portal solution for our customers. With the release of SharePoint 2007 we made the strategic decision to concentrate our service offer solely onto the SharePoint platform. Starting with conception and implementing, project management, system integration, design through to (online) training and hosting.  For all our solution we additionally offer a continuous service concept. .

We are a team of over 20 members and develop individual solution concepts for both, national and international projects.

In order to be successful in the long term, we count on constant development. Our aim is not only to conform to technologic progress, but also, by detecting changes on the market at an early stage, keep a role as a pioneer in the field of market and customer oriented solution development.
