We transform
and scale businesses

Altamont partners with lower middle market businesses at inflection points — bringing capital, operational expertise and a hands-on approach to transform them into scaled, resilient sector leaders.

Our partnership with founders and management teams is built on shared goals, mutual trust and a genuine commitment to building something lasting together.

Our values

Who we are

Business Builders

We advance the companies and management teams we partner with by adding operational and strategic value through our Investment team, Altamont Ascend, functional experts and executive network.



Focused Investors

We invest where we have deep industry experience: Industrials, Business Services and Financial Services.  We have a track record of success partnering with companies to drive growth, operational improvements and value creation.  



Transparent and Aligned Partners

We are committed to open and honest communication, eager to hear new ideas and willing to roll up our sleeves to drive results. We invest our own capital in every company, ensuring our interests are fully aligned with our investors and the businesses we partner with.

Responsible Owners

Both within our firm and in our surrounding communities, we prioritize long-term relationships and shared success. We pioneered broad-based employee ownership in the lower middle market as Founding Partners of Ownership Works™, and through the ACP Foundation, give back to the communities where we operate.

Community & Responsibility

Shared Success

We are believers in the power of culture and employee ownership to energize the workforce and drive company performance that materially benefits both employees and businesses. We are proud to be a founding partner of Ownership Works, a nonprofit with a mission to increase prosperity through shared ownership at work

ACP Engagement

We believe that companies with strong environmental, social and governance practices attract better talent, have fewer business risks and deliver strong results for all stakeholders. We established the ACP Foundation to amplify portfolio company engagement in their communities and to give back to our own, and we are a signatory to the United Nations Principles for Responsible Investment (UN PRI), a global initiative that promotes responsible investing.
