Viburnum Funds

Founder Mark Jones leads the investment committee as Managing Partner. Jones previously worked in Macquarie Group's investment banking division and later directed principal investments at Diversified United Investment, a publicly listed investment company. The firm maintains a flat partnership structure with no external investment committee members.

The firm executes buyouts, management buyouts, public-to-private transactions, and late-stage growth equity rounds. It also pursues corporate carve-outs, recapitalizations, and privatization opportunities. Equity check sizes generally range from AUD $10 million to AUD $50 million, targeting control positions.

Viburnum concentrates on four core sectors: industrial technology and services, healthcare, mobility and transportation, and enterprise software. This focus is not exclusionary — the firm evaluates adjacencies where domain expertise applies — but it does not invest in consumer retail, hospitality, or pureplay financial services.

The firm's Perth headquarters provides a structural sourcing advantage in the Western Australian market. Viburnum primarily originates transactions through direct relationships with business owners, intermediaries in the mining-services and industrial supply chains, and corporate carve-out situations. It does not operate a formal co-investor club, though it has syndicated alongside other domestic private equity managers on select platform deals.

Viburnum Funds is a traditional private equity asset manager, not a family office. It raises capital from institutional limited partners and high-net-worth investors for closed-end funds. The firm is registered in Australia and manages third-party capital under a standard general-partner / limited-partner structure.

Viburnum takes board seats on every platform and typically embeds at least one operating partner into each portfolio company's governance framework. This hands-on model is designed to support management team transitions during buyouts, particularly in founder-led businesses where professionalization is a core value-creation lever.

The firm's investment mandate covers Australia and New Zealand only. While some portfolio companies may earn export revenue from Asia-Pacific markets, all platform headquarters and core operations are domiciled domestically. Viburnum has not made any public cross-border acquisitions.
