Investing in high
growth impact.

Who we are

We are a thematic private equity investment firm backing exceptional entrepreneurs who build solutions to address the world’s largest environmental and social challenges.

Our vision

The greatest businesses of the future are those building solutions to world’s biggest environmental and social challenges today.

We founded MS+PARTNERS because we recognize the need to build sustainable businesses that align purpose with profit.

A society that allocates resources purely based on generating short-term profit is unsustainable. Period. Backing innovative businesses with social and environmental purpose is the greatest investment opportunity of our times – both for planet and profit.

We invest in growth-stage businesses with sustainable, outsized impact potential.

We are in this for the long haul. We do not expect quick exits, and we don’t do deals – we partner with companies, and we help them grow.

Purpose is the single most exciting and powerful incentive tool that we have. We encourage our companies to think about all their stakeholders, to increase both private and social value. Time and time again, we have found that given the choice, consumers, clients, employees and shareholders will work harder for purpose. When purpose is coupled with profit, we can drive change at scale.

Consistency is what creates compound effects over time – it’s not what we do once in a while that shapes our lives. It’s what we do consistently.

We build networks – with every additional investment, we create an exponential node of connections, all driving towards addressing environmental and social challenges.

Our vision is to build the leading European impact investment firm, connecting entrepreneurs with investors, investing with our capital and network to build the businesses of the future.
