Fintech entrepreneur and investor Dom Pym and his fintech-focused venture fund Triple Bubble have forged a strategic partnership Commonwealth Bank’s venture-scaling arm x15ventures to support and scale Australia’s financial technology ecosystem.
The partnership includes an investment, exploration of new fintech opportunities using x15’s bank-safe venture stack, and the development of a mutual mentorship and talent exchange program to give startups founders enterprise insight and provide emerging bank talent with hands-on experience inside high-growth ventures.
The terms of the deal were not disclosed.
x15 managing director Toby Norton-Smith said working with Triple Bubble reflects CBA’s broader strategic vision of connecting startup agility with institutional scale for long-term impact.
“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,” he said.
“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,”
Pym, best known for Up Bank and Pin Payments, cofounded Triple Bubble in 2024 with Brian Collins from Audacity Ventures and Euphemia CEO Judy Anderson-Firth. The name refers to the three ‘bubbles’ fintechs face at the startup, scale-up, and liquidity stages, providing capital, connections, and strategic guidance when founders need it most.
Pym said Triple Bubble takes a stage-agnostic approach that will collaborate with CBA to address gaps they see in fintech.
“This partnership is a bold signal of leadership from Australia’s biggest banking institution,” Pym said.
“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.
“Together, we can unlock opportunities for founders, attract and retain world-class talent, and prove that fintech is one of this country’s great growth engines.”
x15ventures was in founded in 2020, and builds, buys and invests in startups that benefit from connections to the bank and its more than 15 million customers.
