Killik & Co Family Office
Paul Killik founded the Mayfair-based partnership in 1989. It serves London families with portfolios spanning collectibles, venture, and crypto ETPs.
Killik & Co Family Office
Founded in 1989 by Paul Killik, the firm began as a stockbroking partnership in London's Mayfair and has evolved into a multi-generational wealth manager for UK families. Matthew Orr co-founded the business and later established ShareGift, while Paul Killik's daughter Georgie now serves as Deputy Senior Partner and Chief Strategy Officer. The firm cultivates a partnership structure rather than a corporate hierarchy, situating client assets within one of London's oldest independent financial houses. Killik & Co operates across a wide waterfront of asset classes. Private client portfolios mix public equity and fixed income with private equity, private credit, and hedge fund commitments. The family office arm, led by Partner Jer O'Mahony, layers in a dedicated "specialist investments" capability that trades collectibles, cryptocurrency exchange-traded notes, and gold ETCs. Deal activity spans Europe and Asia. The firm's direct-holding strategy touches real estate at addresses like 46 Grosvenor Street, alongside venture exposure in fintech and industrial tech. Confirmed technology interests include AI/ML, biotech, semiconductors, and Web3. Total assets are not publicly disclosed; the firm operates as a private partnership. Altss estimates aggregate client assets at approximately $10.3 billion based on fee and revenue data. The firm has deliberately expanded its physical footprint from Mayfair to branches in Hampstead, Kensington, Chiswick, and Esher. A notable operational marker: Killik & Co became a certified B Corporation in 2024. The Killik & Co Charitable Trust operates alongside client-facing investment activities. Professionals are networked into the London financial community through memberships in the Society of Trust and Estate Practitioners (STEP) and the London Stock Exchange. Killik retains founder control at the Senior Partner level, which differentiates it from bank-owned or consolidator-purchased UK wealth managers. The firm advises both retail and high-net-worth households, but the family office division operates as a distinct multi-family office, cutting direct co-investment checks rather than solely allocating to third-party funds. This hybrid of advisory wealth management and principal-style direct investing places the partnership closer to the model of a continental European family office than a conventional London wealth boutique.

Frequently asked questions
Who runs investment decisions at Killik & Co Family Office?
Jer O'Mahony is the Partner and Head of the Family Office, overseeing the direct investment and specialist asset activities. As a private partnership, the firm involves senior partners including founder Paul Killik in strategic direction, but Georgie Killik, as Deputy Senior Partner, also holds significant influence over the firm's long-term investment architecture. Day-to-day portfolio management is executed by a team of financial specialists distributed across London branches.
How does Killik & Co source proprietary deal flow?
Deal flow originates from the firm's relationships in London's professional and entrepreneurial networks, augmented by decades of operation from its Mayfair headquarters. Membership in the London Stock Exchange and STEP provides access to investment trust boards and family-run enterprises. The firm's specialist investments desk also trades directly in collectibles and passion assets, a channel distinct from standard brokerage-sourced deals.
Is Killik & Co structured as a single family office or does it operate more like a venture firm?
It operates as a multi-family office and wealth management partnership for third-party clients, not a single-family office. The family office division does make direct venture and private equity co-investments, functioning more like a hybrid manager that blends advisory portfolios with principal-style direct deals. This structure makes it closer to a US multi-family office with an operating company than a pure venture firm.
Does Killik & Co participate in fund commitments or only direct deals?
The firm participates in both. Its private-market allocation includes fund-of-funds and hedge fund commitments alongside direct co-investments and SPVs. This dual approach allows clients to access curated manager relationships while also taking concentrated positions in individual opportunities, particularly in fintech, industrial tech, and real estate.
Does Killik & Co maintain philanthropic structures, and how are they separated?
Yes, Killik & Co Charitable Trust operates as a distinct entity alongside the commercial wealth management business. It provides a vehicle for clients and the partnership itself to direct philanthropic capital, primarily through mission-related investing. The trust is administratively separated from client portfolios, though its existence aligns with the firm's B Corp certification achieved in 2024.
Where does the underlying wealth come from?
Killik is a private partnership serving external families; it does not manage a single designated fortune. The founder, Paul Killik, and co-founder Matthew Orr built the business from stockbroking roots, meaning partner capital sits alongside client capital rather than dominating it. The firm serves professionals, entrepreneurs, and London-based families whose wealth typically originates from corporate careers, business sales, and property.
What is Killik & Co's known posture on co-investments alongside external GPs?
The family office actively co-invests alongside external managers, particularly in direct ventures and specialist assets. The model allows clients to replicate the partnership's own investment selection without commingling into a single fund vehicle. Extracted details indicate an appetite for SPVs and club-style syndications in technology and energy transition targets.
