K STREET ADVISOR & INVESTMENT

K Street – Advisor & Investment srl

Private Family Office & Investment Holding

Preserving private capital across generations — and building the companies we own.

K Street is a private family office and investment holding based in Milan. We steward the wealth of a single family with one mandate: to protect what has been built, to grow it responsibly, and to pass it on stronger to the next generation.

As a holding, we take controlling and strategic stakes in operating companies and stand behind them as active owners. We back our subsidiaries with capital, governance, and hands-on competencies — helping them grow, professionalise, and create lasting value. We invest our own capital with a long-term horizon, free from external mandates or third-party fundraising, so that every decision is made with alignment, discretion, and conviction. It is in this spirit that the Ferrulli family entrusts its patrimony to K Street.

What we do

•  Direct, long-term investment — we commit the family's own capital directly, with patience and a multi-generational view.

•  Holding & control — we hold controlling and strategic stakes in operating companies across our core sectors.

•  Support to our companies — we provide our subsidiaries with capital, governance, and in-house competencies to help them grow and create value.

•  Resilience & crisis management — safeguarding the family's interests and its companies through moments of disruption.
