Three Bridges Capital

Konstantin Sidorov, the firm's founder and CEO, leads all investment decisions. The firm operates with a lean team structure typical of discretionary single-family offices, where the principal personally evaluates each opportunity rather than delegating to a large investment committee.

The firm's known activity emphasizes direct co-investments in late-stage companies, but single-family offices of this profile frequently allocate a portion of capital to venture fund commitments to deepen deal-flow relationships. Three Bridges has not publicly disclosed the split between direct investments and LP commitments.

Three Bridges focuses on late-stage venture and growth equity rounds — Series C through pre-IPO — where enterprise traction is established and the risk-return profile aligns with single-family-office capital that prizes capital preservation alongside upside. The firm generally avoids pure seed-stage risk.
