CBA’s x15ventures teams up with fintech fund Triple Bubble

They will develop a mentorship and talent exchange program.

The Commonwealth Bank of Australia (CBA)’s venture arm x15ventures has announced a strategic partnership with Triple Bubble, a fund focused on financial technology (fintech) companies.

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, CBA announced in a press release on 18 September 2025.

“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,” x15 Managing Director Toby Norton-Smith said.

Triple Bubble is a fintech-specific investment fund, designed to support promising early-stage ventures. It was founded in 2024 by Dom Pym (Up Bank, Ferocia, Pin Payments), Brian Collins (Audacity Ventures, Startup Bootcamp), and Judy Anderson-Firth (Euphemia, Startup Victoria).

Founded in 2020, x15ventures is a venture scaler powered by CBA. It buys and invests in startups that it believes would benefit from connections to Australia’s leading bank.

CBA and x15ventures expect these startups to help improve the lives of CBA’s 15 million customers by either reimagining existing products or services, or offering solutions not traditionally classed as finance but can extend CBA’s relationship and relevance with its customers.
