Building Europe's next generation of category leaders.

Who we are

Image

We are a European thematic private equity firm investing in growth mid-market companies where sustainability drives productivity and resilience.

Our vision

We founded MS+PARTNERS with a simple belief: the next generation of leaders will be built by companies aligning long-term purpose with performance. Across Europe, businesses embedding sustainability into how they operate are becoming more productive, more resilient and better positioned for durable growth — creating one of the defining investment opportunities of our time.

We partner with founder-led businesses in the growth mid-market at pivotal scaling moments, bringing institutional buyout discipline, thematic insight and long-term capital to help build enduring market leaders. Our role goes beyond investment — we work alongside entrepreneurs to strengthen governance, expand internationally and compound value over time.

We believe lasting success is rarely linear. It requires patience, consistency and a balance of humility and audacity. Through active ownership and long-term partnership, we aim to build a leading European investment firm connecting capital, expertise and entrepreneurial ambition to scale the businesses shaping tomorrow’s economy.
