TDJ

Jacek Leonkiewicz, as President of the Management Board, leads strategic and investment decisions across the group. Each of the three divisions — TDJ Estate, TDJ Equity, and TDJ Venture — has its own managing director with day-to-day operational authority, but major capital allocation and acquisition approvals flow through Leonkiewicz and the board.

TDJ operates as a hybrid: a permanent-capital industrial holding group that does not raise third-party funds. Its family-office heritage and use of proprietary capital distinguish it from closed-end private equity funds, though its active control investments and divisional structure mirror an institutional PE platform. The firm is registered as an asset manager in Poland under its holding-company entity.

TDJ covers the full company lifecycle through its three divisions. TDJ Venture targets early-stage and growth-equity technology investments, while TDJ Equity takes control positions in established mid-market industrial and service companies. TDJ Estate develops real estate projects from greenfield through operation.

TDJ does not publicly maintain a formal exclusion list, but its portfolio shows no exposure to consumer retail, hospitality, or speculative financial services. The group concentrates on industrial technology, energy transition, enterprise software, and property development — sectors where its permanent-holdings model aligns with long asset lives and operational complexity.

TDJ deploys proprietary capital rooted in the Leonkiewicz family's industrial holdings. The firm does not disclose its balance-sheet size or asset base. By not raising external funds, it retains full discretion over holding periods and reinvestment decisions, which is central to its strategy of indefinite ownership.

TDJ sources primarily through the Leonkiewicz family's multi-decade industrial network in Poland, direct corporate carve-outs from European conglomerates, and relationships with local operating partners. The firm's permanent-capital reputation allows it to approach founders and corporate sellers offering indefinite partnership, a counterpoint to the 5-to-7-year fund-life standard in the region.

Yes, the TDJ Foundation serves as the group's philanthropic vehicle, funding educational and cultural programs in Poland. The foundation operates separately from the investment divisions, though it draws funding from the family's overall capital base.
