Founded in 1993 in Gravellona Toce (Verbania), the GMM group is recognized as the international leading brand in the bridge saw machines for stones proved by the wide diffusion of installed machines in the world (around 6.500).

The company has two production plants in Italy and two foreign branches to serve the North America and the Asia Pacific markets.

In June 2016, the CPEF III acquired a majority stake in GMM through a buy-out transaction.

In June 2018 GMM acquired a 70% stake in TWJ, an Australian company specialized in waterjet machines for metal, stones and composite materials. The acquisition allowed the GMM group to complete its product range with a state-of-the-art technology.

In January 2022, GMM acquired a 52% stake in Bavelloni, an Italian manufacturer of equipment and tools for flat glass processing. The acquisition contributed to the group’s growth in size, allowing GMM to reach a turnover of more than €100 million and approximately €10 million of Ebitda, giving rise to one of the world’s leading brands in the sector.
