Cornerstone Investment Management

What Cornerstone Investment Management does

Cornerstone Investment Management (legal entity: Cornerstone Partners Sp. z o.o.) is a privately held private equity investment management firm founded in 2001 and headquartered at ul. Żurawia 8, Warsaw, Poland, with a regional office in Amsterdam, Netherlands. The firm has been sourcing and executing investments across Central and Eastern Europe for over 20 years, operating across economic cycles in private equity, credit, and real estate. Its stated strategy targets opportunities with positive economic impact and long-term value creation, serving institutional investors including pension funds, insurance companies, and sovereign wealth funds through direct relationships. The team is drawn from global corporations in finance, investment, banking, real estate, and technology, with hands-on operating experience managing large businesses.

The firm's portfolio is centered on two pillars. The first is a commercial real estate holding anchored by V Tower, a 22-storey Warsaw office building of approximately 30,000 square metres gross lettable area, acquired from Globalworth in 2023 and refinanced in February 2026 via a unitranche facility from P Capital Partners in a joint venture with EFF. The second pillar is a veterinary services consolidation platform under the LuxVet Group brand, integrating advanced specialist clinics (AMVET in Gdańsk and Kraków, featuring CT, MRI, and endoscopy) with multi-location operators, including Mobile Vet's 8 clinics and pharmacies in Romania. The firm is run as a single investment platform, distributing institutional capital directly, and supplements deal activity with thought-leadership programming through its Impact 26 platform.

Cornerstone monetizes through investment management and carried interest on institutional capital, with terms negotiated individually with limited partners; specific fees are not publicly disclosed. Revenue is not publicly reported. The firm is privately held (no IPO), has no parent company disclosed, and does not maintain a mobile application or public AI/research footprint. Its most public activities in 2026 — V Tower refinancing, Mobile Vet integration, AMVET–LuxVet consolidation announcement, and Impact 26 — reflect an active deal cadence and a clear vertical and geographic build-out thesis in CEE rather than scale through new fundraising disclosures.
