Investment thesis
B3 Holding is the Bruzek family's private investment vehicle, deploying only family capital with long-term horizons rather than pure profit maximization. Rooted in the family's background in the chemical industry (notably Draslovka Kolin), the firm seeks investments that address broader societal challenges, with particular interest in healthcare, diagnostics, agriculture, energy and chemistry. Positive capital returns are only one of several criteria used to evaluate a holding. Investments are managed directly by B3 Holding's own management or through mandated funds that share the family's values and ethical standards.
