Established in 2014, PrimeStone takes substantial stakes in European listed companies that it believes have significant potential for value creation.

PrimeStone was founded by three former partners from The Carlyle Group, who specialized in buyouts and have invested and worked together across Europe for more than 15 years. They all also share a prior experience as consultants in strategy and operational improvements with The Boston Consulting Group.


PrimeStone typically targets medium-sized, listed European companies that have significant value creation potential through strategic, operational or financial improvement. PrimeStone creates value by taking a long term perspective, adopting an active approach and having a significant influence over its underlying investments through a constructive dialogue with boards and management teams.
