Constantinople is a Sydney-based fintech providing an AI-native core-banking platform that lets banks run product, technology, data, operations, and compliance as a single modern fabric. It powers retail, business, and embedded banking across accounts, payments, cards, lending, mortgages, and term deposits, with headless APIs and SDKs, digital onboarding, an AI concierge for customers, and the "Justinian" AI workbench for bankers. Risk and compliance (fraud, financial-crime detection, regulatory reporting) are built into the platform, which is SOC 2 Type II and ISO 27001 certified. Constantinople is backed by Prosus Ventures (Series A, A$50M). The developer/API surface is a gated B2B platform; enrichment here is sourced from the company's public web presence.
