Investment Philosophy

We are in the midst of an economic shift to a new economy that is resilient, regenerative, inclusive and in service for all stakeholders.

Purposeful companies actively seeking capital to solve the world’s most pressing environmental and social problems coincides with investors’ desire to make conscience investments – aligning their money with their values. Investors want to engage in the investments they make, while company founders seek capital that doesn’t require them to relinquish equity or control over their company.

At Montcalm Capital, we have created a fund that will shift the paradigm, allowing our portfolio companies to thrive without their stakeholders sacrificing equity, vision or control.

Investment Process

We work with companies to provide them with flexible capital that best aligns with their stage of development and business needs. Each portfolio company undergoes rigorous institutional due diligence followed by a highly customized process of deal structuring.

We favor investments structured with corporate debt securities. Our portfolio companies thrive from the competitive cost of capital without sacrificing equity or control. Our investors benefit from expected, competitive returns from companies solving the world’s most critical challenges, while paying no management or administration fees. We recognize that equity investment structures can also be beneficial depending on the company stage and needs, and our fund structure allows us this flexibility when suitable. Our goal is to deliver investing and capital markets back to the basics — a transaction between two people where both parties win while making a positive impact on the world.
