## 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.
