History

From the trade. For the trade

The Offene Systeme Software! team has its roots in the promotional products trade – that’s why we know exactly what matters.

  1. 1970s

    The search begins

    In the mid-1970s the Appel team – a sales agency and promotional products wholesaler – looks for suitable software. No standard program meets its needs.

  2. Then

    Tailor-made in Karlsruhe

    Experts from the Technologiefabrik Karlsruhe develop a custom solution. Appetite grows with eating: a young developer keeps extending it.

  3. Windows

    A new standard

    With MS Windows, the old software reaches its limits. After seven years of development experience, none of the available packages passes the future check.

  4. 1996

    The decision

    In autumn 1996 the team decides to build its own software on the MS Office platform. Work on KS1 begins.

  5. 1997

    KS1 goes live

    In mid-1997 the first version of KS1 goes into production.

  6. 1998

    Founded

    In early 1998 the department is spun off and Offene Systeme Software! is founded to market KS1.

  7. 2017

    20 years

    PSI Journal publishes a portrait for our 20th anniversary.
