The Longs Peak

Our core values are why we’re the best at
what we do. Here’s a look at why you’re
going to want to choose Longs Peak.

Who we are.

Longs Peak is a purpose and values-driven company. It is our mission to make investment performance information more transparent and reliable—empowering investors to make better, more informed investment decisions.

At the onset, we were looking to help smaller investment managers by giving them access to professional performance experts and tools typically only available to very large firms. We know that our work enables emerging managers to compete with the big guys and helps facilitate their growth. We strive to be our clients’ most valued outsource partner and to be known for our exceptional client service. But we know that providing exceptional client service means that we must first create a culture that lives by the ideals we are trying to create for our clients. A place where incredibly talented individuals are empowered to put their best work into the hands of clients that truly value what we do. As a firm, we recognize that our greatest asset is people – both those we work with and those we work for. We continue to evolve into something that represents the needs of both of these groups and hope someday a GIPS Report is provided to every prospective investor in the world.
