Xilium Capital
Xilium Capital is a Sydney-based early-stage VC combining direct investment with an in-house venture-building arm for Australian technical founders.
Xilium Capital
Xilium Capital was founded in 2020 in Sydney by Thomas Fu and Adrian Yusuf. The firm emerged as Australia's venture ecosystem was undergoing a structural maturation, moving beyond mining and real estate wealth into institutionally-backed technology investing. The firm deploys pre-seed through Series A capital with a heavy tilt toward enterprise software, fintech, digital health, and agri-food tech. Xilium operates a concentrated portfolio model, pairing direct investments with an in-house venture-building capability that provides engineering, product, and go-to-market resources to founding teams. The geographic focus is Australia and New Zealand, though portfolio companies often expand into the US and Southeast Asia. Known investments include a B2B payments infrastructure company and an enterprise SaaS platform in the agri-supply chain sector, though the firm maintains a characteristically private posture regarding its full portfolio. Xilium remains deliberately small in team size, prioritizing operating partners over fund administrators. The founders split responsibilities between investment origination and platform support, with no intermediate investment committee layer. The firm historically favored solo-GP-style speed, though it has gradually professionalized its back-office and LP reporting. Structurally, Xilium's 'builder' model represents a genuine departure from the Australian VC norm of passive minority investing. By housing a dedicated engineering and product crew within the firm itself, Xilium functions as a hybrid venture studio, allowing its GPs to write smaller initial cheques with greater follow-on conviction after internal de-risking.

Frequently asked questions
Who makes investment decisions at Xilium Capital?
Co-founders Thomas Fu and Adrian Yusuf lead all investment decisions jointly. The firm operates a flat decision-making structure without a separate investment committee, which allows for rapid commitment to pre-seed and seed-stage rounds. Both principals maintain active involvement in portfolio company development through the firm's builder platform.
How does Xilium Capital source proprietary deal flow?
Xilium sources primarily through deep operational networks in the Sydney and Melbourne startup communities, leveraging its builder platform as a magnet for technical founders seeking more than passive capital. The firm's engineering and product resources attract entrepreneurs who need hands-on support rather than just a cheque, creating a natural filtering mechanism in its origination funnel.
Is Xilium Capital structured as a standard venture firm or a venture studio?
Xilium operates a hybrid model. It makes direct venture investments from a traditional fund structure while simultaneously maintaining an in-house venture-building arm that provides dedicated engineering, product, and go-to-market resources to portfolio companies. This differentiates it from standard Australian venture firms that typically offer only capital and light-touch advisory support.
What investment stages does Xilium Capital typically target?
The firm focuses on pre-seed through Series A rounds, with a strong preference for leading or co-leading first institutional rounds. Xilium's builder model allows it to enter earlier than many competitors, sometimes participating in pre-product or pre-revenue stages where its internal technical resources can materially reduce execution risk for founding teams.
Does Xilium Capital participate in fund commitments or only direct deals?
Xilium deploys exclusively through direct equity investments into operating companies. There is no public record of the firm making fund-of-fund commitments or investing in other venture capital vehicles. Its operational model requires board-level engagement or active collaboration with portfolio company management.
Which sectors does Xilium Capital explicitly avoid?
Xilium has not publicly articulated explicit sector exclusions. However, its builder model and technical operator lens suggest low appetite for capital-intensive hardware, medical devices, or sectors where the firm cannot directly contribute operational leverage beyond capital. Its historical public focus has remained firmly within enterprise software, fintech, and adjacent digital-native categories.
What is Xilium Capital's known posture on co-investments alongside external GPs?
Xilium co-invests selectively with both domestic Australian funds and international venture firms, particularly when portfolio companies expand into US or Southeast Asian markets. The firm prefers to lead or co-lead rounds where its builder resources can be applied directly, but will follow established international leads for later-stage rounds when strategic alignment exists.
