Partnering for Growth

Essex Bay Capital invests in small to mid-sized private companies, partnering with management teams to accelerate growth. 

With over 20 years of investing experience, and more than 70 completed acquisitions, our proven team brings more than just capital to the equation. We are long-term investors, focused on creating sustainable value.  We build companies, both organically and through add-on acquisitions, with a goal of becoming market leaders in their respective niches or geographies. 

Partnership and alignment are at the core of everything we do. We pride ourselves on being transparent and supportive, with the resources, insight and expertise to create win-win opportunities for our partner management teams.


We invest in small to mid-sized companies that are seeking a partial or full ownership transition and/or where there is a need for capital and resources to help trigger the next phase of growth. We invest committed capital, with the ability to supplement as needed with equity from institutions and individuals with whom we’ve had long-term relationships. We look for healthy companies that have sustainable value propositions, and where the opportunity exists to significantly grow the business, both organically and through add-on acquisitions.
