The Commonwealth Bank’s venture-scaling arm, x15ventures, and fintech-focused fund Triple Bubble have formed a strategic partnership aimed at supporting innovation in Australia’s financial technology sector.
The collaboration involves an investment, the exploration of new fintech opportunities using x15’s bank-compliant venture framework, and the establishment of a mentorship and talent exchange programme.
This will enable startups to gain enterprise-level insight while providing Commonwealth Bank staff with experience in high-growth ventures.

“We’ve built a model that’s proven effective in helping startups scale while deepening the CommBank proposition, but there’s always room to improve, especially in how we identify future ventures and talent,”
said x15 Managing Director Toby Norton-Smith.
“Partnering with Triple Bubble strengthens our role as a bridge between corporate and startup, opening venture opportunities that can benefit from our capability, while giving fintech founders and bank talent the chance to learn complementary skills.”
Triple Bubble is described as Oceania’s first fintech-specific investment fund, established in 2024 by Dom Pym (Up Bank, Ferocia, Pin Payments), Brian Collins (Audacity Ventures, Startup Bootcamp), and Judy Anderson-Firth (Euphemia, Startup Victoria).
Its model is designed to provide support at the startup, scale-up, and liquidity stages, which it terms the three ‘bubbles’ where fintechs often require the most assistance.

“This partnership is a bold signal of leadership from Australia’s biggest banking institution,”
said Pym.
“Our fintech ecosystem is thriving but still underserved. What fintech founders need is capital, access to mentors, and large companies that believe in them. With CommBank stepping up, we’re bridging critical gaps in Australian fintech investment and showing real commitment to bold ideas and the entrepreneurs behind them.”
According to Commonwealth Bank, the agreement reflects its wider strategy of combining startup agility with institutional scale to generate long-term outcomes in financial services.
