Firlej Kastory

Firlej Kastory began operations in 2019 under four named founders drawn from M&A law and deep-tech policy backgrounds. The partnership manages private capital for entrepreneurial families without a single disclosed wealth source. The firm allocates across early-stage, growth, and pre-IPO opportunities through direct co-investments, SPVs, and fund-of-funds structures. Confirmed holdings include Ramp Network and Authic in addition to residential assets Wilanowska Point and Bemowo Luxury in Warsaw. Geographic reach spans Europe, North America, Asia, the Middle East & Central Asia, and Oceania. Sector exposure covers FinTech, Digital Health, Energy Transition & Renewables, ClimateTech, SpaceTech, PropTech, InsurTech, AgriTech & FoodTech, Robotics & Automation, and Mobility & Transportation. No headcount or AUM figures appear in public materials. The firm lists membership in PSIK and the Polish Business Roundtable. Philanthropic vehicles include Fundacja im. Ludwika Kastory and Ronald McDonald Foundation Poland. No operational events from the last 24 months are recorded. The structure separates investment activity from the founders’ operating roles at Corporate Profiles DDB Group and Expeditions Fund, creating a distinct governance layer between family capital and external professional commitments.
