The Most Connected Executives on the Warsaw Stock Exchange
Mapping the board interlock network of Poland's corporate elite
Board Interlocks: The Hidden Network
When an executive serves on the board of more than one company, they create a board interlock — a direct connection between those companies through a shared decision-maker. These interlocks form a network that shapes information flow, corporate strategy, and governance practices across the market.
Our analysis of 15 major WSE-listed companies reveals a surprisingly dense network of connections.
The Numbers
Across our dataset, we identified over 3,400 board-level connections between executives. The most connected individuals serve as bridges between multiple companies, often sitting on both management and supervisory boards across the market.
Who Are the Super-Connectors?
The most connected executives tend to fall into two categories:
Professional supervisory board members who serve on multiple supervisory boards simultaneously. Polish corporate governance allows this, and it's common for experienced professionals — lawyers, accountants, and former executives — to hold several supervisory mandates.
Executives who transition between companies over their careers, accumulating connections at each stop. A CEO who moves from one WIG20 company to another carries their network with them.
Why It Matters
Board interlocks are not inherently good or bad. They can:
- Facilitate knowledge transfer between companies
- Align governance practices across the market
- Create potential conflicts of interest when connected companies compete or transact
The EU and Polish KNF regulators increasingly scrutinize "overboarding" — the practice of sitting on too many boards simultaneously — as a governance risk.
