Investment thesis
B3 Holding is a family investment fund that invests exclusively its own capital in pursuit of family values rather than pure profit maximization. Rooted in the family's chemical-industry background (notably Draslovka Kolín), the fund seeks long-term projects that address broader societal problems, with particular focus on healthcare, diagnostics, agriculture, energy and chemistry. Investments are managed directly by B3 Holding's management or through mandated funds sharing the family's ethical standards. Positive capital returns are considered only one of several criteria when evaluating an investment.
