Nashville, Tennessee
A long-term home for essential services businesses.
Dune Services Group acquires established, owner-led services companies — and stays to run and build them. We partner with founders who want a successor that will honor what they built.
Backed by leading investors
Our approach
We don’t flip companies. We build them.
DSG is an operator-led holding company backed by committed capital from a group of institutional investors. We acquire one great business at a time, lead it full-time after closing, and invest for the long run — preserving the people, culture and customer relationships that made it successful.
01
Patient ownership
No fund clock and no pressure to sell. We hold and grow businesses for the long term.
02
Hands-on leadership
Our founder joins the business full-time after closing, working alongside your team every day.
03
Legacy first
Your name, your employees and your customers stay at the center of every decision we make.
04
Fair, flexible terms
Fair valuations and structures built around your goals, including continued ownership where it fits.
Ready to partner — and built to close.
Selling a business you spent a career building should be straightforward. We make commitments up front so owners know exactly who they are working with.
Committed capital
Equity is committed by our institutional investor group, so there is no financing contingency to wait on.
Experienced deal team
Nearly a decade of private equity experience leading and closing platform and add-on acquisitions.
Thematic conviction
We’ve studied our industries in depth before we call. We understand your business, your customers and what drives value.
Efficient closing
No elaborate structures. We prefer clean transactions that close in 30–60 days.
Investment focus
Essential services that keep America running.
We look for durable, founder-built companies whose customers rely on them year after year.
