Within our target industries (recurring services, media and communications), Housatonic Partners will selectively invest in buyouts backing both new and incumbent management teams. As an experienced partner with over $1 billion of capital under management, we can add financial clout and sophistication to seasoned managers looking to acquire companies.

In every transaction we hope to forge lasting, long-term relationships with our portfolio company managers. Accordingly, the managers in Housatonic-led buyouts typically receive significant equity stakes in their companies while retaining daily operating control.
