What Cornerstone Partners does
Cornerstone Partners (legal name: Cornerstone Investment Management) is a privately held, Poland-based private equity investment management firm founded in 2001 and headquartered at ul. Żurawia 8 in Warsaw. According to its own materials, the firm has spent over 20 years sourcing and executing investments across all economic cycles and market conditions, with a stated strategy of seeking opportunities that deliver positive economic impact and long-term value creation. Ownership is described as resting with Przemysław Krych and Maciej Dyjas.
The firm's single core offering is private equity investment management, executed by a small team (11–50 employees) whose members previously held operational roles at global corporations across finance, investment, banking, real estate, and technology. Cornerstone monetizes through management fees and carried interest on capital deployed via its funds, with no public pricing or product packaging disclosed. Its GTM is a direct institutional relationship model — engaging institutional investors, family offices, and high-net-worth individuals for fund commitments through its corporate website and LinkedIn presence rather than through intermediaries or retail channels.
Cornerstone's portfolio spans multiple verticals; confirmed holdings in the input data include IT Kontrakt (acquired directly in April 2017) and the veterinary care platform LuxVet Group, into which Mobile Vet clinics were absorbed in March 2026 and which combined with AMVET in April 2026. The firm also surfaced an 'Impact 26' initiative in May 2026, indicating an evolving impact-investing positioning. Revenue, AUM, fund sizes, and customer-level data are not publicly disclosed, limiting quantitative analysis of the platform.
