INVESTMENT APPROACH

Before industry, financials, or company size, we look for character. We partner with retiring business owners who care deeply about their company and the people who helped build it. We focus on business-to-business companies in niche industries with strong competitive positions and the potential to scale nationally or globally.

For Stakeholders

A Customized Partnership

When an owner chooses Granite Partners, we build a customized plan together — one that fits the owner’s timeline and matches their vision of what comes next. Partnership options can include a combination of cash, ongoing company ownership, Granite membership, leadership equity opportunities, and owner’s notes. This range of options gives an owner flexibility as they transition to their next chapter.

Value Proposition for Owners

We buy to own and grow companies over generations. This means:

Peace of mind. We invest in all stakeholders, and especially your team. We have grown net jobs year-over-year and through the Great Recession and the COVID-19 pandemic.

Enterprise strength. We have a collective $2.4 billion in enterprise value, and we bring a series of growth resources and tools to help empower company leaders.

Long-term impact. We value the impact of your business on all stakeholders. Throughout the Granite community we foster wellbeing and community engagement.
