The Quantum Story: All In On Entrepreneurship in Energy

Entrepreneurship has been in Quantum’s DNA from the very beginning. Wil VanLoh founded the firm in 1998 at the age of 28 upon recognizing an untapped business opportunity to provide private equity capital to entrepreneurs in the upstream oil & gas sector.

Over time, our vision and scope have expanded as we recognized emerging opportunities across the energy value chain and as a result of the increasing focus on sustainability. Today, we pursue a disciplined yet creative approach to investing across the Sustainable Energy Ecosystem. While much has changed since Quantum’s founding, we continue to believe our biggest competitive advantage is the ability to attract and provide value-added support to entrepreneurs we partner with to build great companies.

What Sets Quantum Apart

Having built one of the leading global private equity franchises focused on the Sustainable Energy Ecosystem, Quantum seeks to attract leading energy and sustainability entrepreneurs to be its partners. By investing in all things energy, we better understand the interplay across the energy value chain, which is increasingly critical given the challenge of achieving net-zero emissions.


Quantum also provides more than just capital to its portfolio companies. We pride ourselves on being value-add, hands-on partners, and we invest in our own business accordingly. Our in-house Strategic Shared Services team allows us to propel our partner companies to a higher level.
