Frequently asked questions

Who runs investment decisions at 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.

Does TDJ invest in early-stage companies or only mature businesses?

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.

Which sectors does TDJ explicitly avoid?

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.

Where does TDJ's investment capital originate?

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.

How does TDJ source deals in Central Europe?

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.
