Private investment firm taking long-term majority stakes in business and technical services companies

Keystone Capital is a private investment firm that puts patient, long-term money into established companies. Its founders bought a small business services company in 1994 and ran it themselves before merging it into a larger listed group.
That operating background shapes how the firm works. It aims to sit alongside management teams and make decisions with a long horizon.
Businesses in four areas: engineering and technical work, professional services with a technology element, general commercial services, and industrial technology with engineered products. It prefers majority control and continuity of the existing leadership.
