Inverness Graham Investments

Ken Graham spent two decades running Graham Packaging, an industrial manufacturing business, before founding the firm. That operator DNA shapes a buy-and-build approach where Inverness Graham embeds operational specialists inside portfolio companies rather than relying exclusively on board-level governance. The firm preferentially targets founder-owned businesses where it can apply this operational playbook to accelerate growth.

There is no ongoing ownership relationship. Ken Graham sold Graham Packaging to the Blackstone Group in 1998, prior to founding Inverness Graham. The firm operates entirely independently as a private equity manager and does not invest on behalf of the Graham family's industrial entity.

Inverness Graham focuses on platform investments in companies with $5 million to $20 million in EBITDA. The firm executes majority buyouts, growth equity investments, and add-on acquisitions, typically writing equity checks between $15 million and $75 million per platform.

The Advisory Board gives portfolio companies direct access to former C-suite executives from large industrials and service businesses. This board is a structural commitment to the firm's operator-centric philosophy and supplements the deal team's own expertise with deep functional knowledge in supply chain, commercial strategy, and organizational scaling.

Although the firm carries the Graham name and operates with a family-office-like long-term orientation, it manages third-party institutional capital and operates as a registered investment adviser. The firm runs commingled blind-pool funds with limited partners rather than a single-family balance sheet.

Ken Graham remains Senior Managing Principal, but the May 2024 promotion of his son James Graham to Managing Principal signals a generational transition. The firm is positioning for continuity under family leadership while maintaining its institutional fund structure.

The firm invests primarily in North American companies, with particular concentration in the United States. It does not promote an explicit international strategy, though many of its portfolio companies derive revenue globally through export or international subsidiaries.
