Cornerstone Capital Holdings

The named Principals, Jonathan Alt and Andrew Bushell, lead the firm's investment activities. An Operating Partner, Ian Ballinger, provides portfolio-level oversight on acquired businesses; the Director of Business Development, Garrett Kramer, handles deal origination. No separate chief investment officer is disclosed.

Sourcing is built on acquiring “orphan” divisions from public and private corporations. Cornerstone believes large-cap owners often shed non-core manufacturing assets, and the firm pursues these directly through private sales, management-driven buyouts, and corporate carve-outs. A public list of avoided sectors further focuses conversations on industrial targets.

It operates as a diversified holding company and asset manager, not a family office. The strategy mirrors long-duration private equity — acquiring and operating businesses indefinitely rather than within a traditional fund-life constraint — but the capital is not publicly disclosed as family wealth.

Only direct deals. The firm's model is equity ownership of operating companies via corporate divestitures and direct buyouts. There is no indication of fund-of-fund commitments or LP positions in third-party vehicles.

Cornerstone targets mature, revenue-generating manufacturing and industrial service businesses — often underperforming divisions with “foundational integrity” — and explicitly declines early-stage businesses. The focus is on buyout, management buy-in, and recapitalization of existing middle-market companies.

The firm publishes a firm-wide avoidance list: software, technology companies, restaurants, early-stage businesses, real estate development, retail, and construction. This is intended to eliminate deal flow outside its core industrial manufacturing and aerospace mandate.

The origin of Cornerstone's investment capital has not been publicly disclosed. No wealth-creating event, founding family, or underlying source of funds is stated by the firm or reported in available records.
