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.
