Digital signatures – made & hosted in Germany



Although digital workflows have become established for a wide range of applications, there are still gaps.

Contracts and other documents requiring a handwritten signature are often still signed on paper. This not only involves setting up heavy ring binders and laboriously scanning a variety of documents, but also means making inefficient use of valuable resources.

Our inSign software has been on the market for more than ten years, and we are also the market leader in the insurance and banking industry. Use electronic signatures to expedite your internal and external business processes. Fully legally binding and GDPR compliant. For companies of all sizes, as well as freelancers and the self-employed.

Find out for yourself how easy it is to use and what convenient features it has. We would be happy to offer you the opportunity to test our electronic signature solution free of charge.
