Company history – Our milestones

Founded in 1986

The history of MAIN-TOOL begins

The goal was formulated in 1983: the creation of an EAM (Enterprise Asset Management) or an IPS (Maintenance and Planning System). In cooperation with the associations DKIN, VDI, VDMA, VDBUM and REFA, we outlined an initial information system for the maintenance planning of plants and machines.

The birth of MAIN-TOOL

After almost two years of development, “MAIN-TOOL System 1” based on DBase (Microsoft) is completed and delivered to customers. Beiersdorf AG in Hamburg becomes the first official MAIN-TOOL customer.

MAIN-TOOL System 2

After a development period of 2 years, “MAIN-TOOL System 2” is completed and delivered to existing and new customers.

The international breakthrough

“MAIN-TOOL System 2” becomes international through the use of Schering AG. At the end of the year 1000 users use MAIN-TOOL.
