We Build Companies.

Founded in 1999, Rockwood is an operationally-focused investment firm serving the lower middle market. We invest in corporate divestitures/carve-outs, as well as privately-owned manufacturers, value-added distributors and industrial services companies. Situationally, the companies we partner with often are seeking transformational change, or may have more complexities to the business situation or transaction. Rockwood invests out of its committed capital funds in companies headquartered in North America with $2 to $7 million in EBITDA (revenues typically $10-$75 million) for initial platform investments and will consider add-on investments of any size and geography.

Our firm’s mantra is “We build companies.” Because Rockwood often is the first outside investor in a transaction, management benefits from our “owner mindset” and partnership approach to adding value and equipping businesses with the tools, support and resources they need to achieve their potential. We have deep expertise serving businesses in regulated industries, including process control, and partner with companies that have leading shares in their respective niche markets.
