Amalthée was created by a family of entrepreneurs to invest over the long term and grow its financial resources.

New investors that share our convictions have joined this initiative, attracted by its differentiated approach and the alignment of interests between the partners.

Getting to know us

C. Drost, whose family was from the Netherlands and worked in a meat trading company, moved to Brittany in 1969 to develop the family business. After three decades of hard work, the family group was sold in the early 2000's to secure the company's future in a sector experiencing significant consolidation.

The proceeds of the sale were entrusted to various private banks in Paris. Diverging interests and an evident lack of transparency in relations led to growing dissatisfaction. The family then decided to take initiative by developing an approach focused on the long term and on transparency.

Solid experience in financial management combined with the trust of family members naturally led Olivier, one of the three children, to create a fund in 2010. The fund now combines the bulk of family capital within a simple and understandable investment process: high-quality companies that are held over the long term.

Entrepreneurs facing similar issues have been attracted by this transparent and independent approach. As a result, they have gradually joined the venture on the same terms as the first investors.

Amalthée is now a team of four people, three of whom are dedicated to investing for about 20 clients.
