HISTORY
The history of SMF begins in 1985

In 1985, the IT world still looked like this: E-mails were called letters and cost 50 pfennigs, typing was done on an electric typewriter and telephones were not mobile. It was at this time that three young computer scientists decided to take the step into self-employment.
Diethard Feuerstein founded his own company, today’s SMF GmbH, together with his wife Angela Feuerstein and brother-in-law Walter Müller. Since its foundation, the company has been on the market for more than three decades and will remain in family hands in the future.
Our history
With Henrike Simbach and Wieland Feuerstein, the next generation is already in the starting blocks and will continue to follow the company’s motto: ‘know the existing, master the current and plan for the future’.
The history of SMF is characterised by milestones that show how the first ‘company headquarters’ in the converted attic became a successful IT company.
