All-in-one software and ops platform for banks. MoreLess
Constantinople is a Sydney fintech building a comprehensive software and operational platform for banks — an all-in-one B2B layer covering core banking operations so institutions can launch and run digital banking services more efficiently. Co-led by Dianne Challenor among others, the company targets banks seeking an integrated foundation rather than piecing together point solutions. Revenue comes from providing the platform and related operational support to banking clients. Constantinople raised A$32 million in seed funding and A$50 million in Series A (Prosus Ventures lead, with AirTree, Square Peg and Great Southern Bank). In August 2026 it raised A$62.5 million in Series B funding from AirTree Ventures and Square Peg Capital to scale the banking platform. Keywords: banking platform, core banking, fintech, B2B SaaS, digital banking, Series B, AirTree, Square Peg, Australian fintech.
