Partnership

our story

Trimountain Partners was founded on a clear principle: backing talented and well-invested founder-owners, entrepreneurs and management teams through "partnership-style" transactions that reflect our values – integrity, transparency, and genuine partnership.

We believe exceptional investments aren’t built on contracts or egos – they’re built on trust, chemistry, shared vision, alignment and strong relationships. That’s why we approach every partnership with humility and openness, working closely with entrepreneurs and management teams in a non-intrusive but value-added manner, to unlock enduring value.

As a middle market private equity team focused on founder, entrepreneur and management-led businesses, our success is rooted in empowering the exceptional people we invest in and focusing on situations where the choice and quality of partner is paramount. We understand the diverse challenges and opportunities founders, operators, and stakeholders face in today’s dynamic landscape. We bring experience, perspective, and a sincere desire to learn – because your insight is just as valuable as ours.

Whether you're scaling, transitioning, or exploring what’s next, we’re here to build something meaningful – together.

Approach

We are a seasoned team with deep expertise across business services, consumer and education. What sets us apart is not just our sector knowledge and flexible approach to structuring deals – but our straightforward, down-to-earth approach.

We operate with a lean team of senior investment professionals, enabling fast, high-conviction decision-making. With decades of experience, we’ve structured and negotiated a wide range of transactions. We are able to take majority or active minority positions, and can invest with a long-term mindset if the opportunity calls for it. Our goal is to tailor each investment to the situation, ensuring strong alignment across all stakeholders. We operate as one team with the companies and teams we back – success is shared.

We invest where Trimountain has a clear edge and where the investor truly matters. Rather than relying on financial engineering, our value creation is driven by sector insight, access to senior operating talent, and hands-on strategic and financial support where required. We bring best-in-class governance and work closely with management teams and entrepreneurs – always as shareholders, never as operators.

Phil Miller | Group CEO of ABCA

"The partnership with Trimountain has been genuinely transformative for ABCA. Their support has helped us expand our capabilities, invest in our team, and pursue growth in ways that feel both ambitious and sustainable.

From the very beginning, they took the time to understand our family business and our people. We have retained meaningful stakes in the business, and there’s a genuine sense that we’re building together. 

What’s stood out most is their partnership approach and long-term mindset. We are delighted to be working with Ali and his team again post the completion of the Continuation Vehicle in June 2025."
