Simplify's Take

What believers are saying

  • August 2026 funding lifted Constantinople to A$62.5 million, signaling strong investor conviction.
  • Dealroom says eight banks use the platform, with two more expected by year-end.
  • Move Bank reported a 30 percent cost-to-income reduction after the 18-month migration.

What critics are saying

  • Eight-bank concentration makes every failed migration a material revenue and reputation shock.
  • Banking migrations invite outage, compliance, and fraud failures; one incident kills trust fast.
  • A catastrophic migration failure at Move Bank would freeze sales and threaten the company's survival.

What makes Constantinople unique

  • Move Bank’s August 2026 full migration proves Constantinople runs entire-bank operations, not just software.
  • Its platform bundles onboarding, compliance, fraud, payments, and core banking into one stack.
  • Partnerships with Paymentology and 10x Banking extend card issuance and core integration globally.

Constantinople chooses UK fintech Paymentology to power its Banking-as-a-Service growth and accelerate payments innovation in Australia

Constantinople chooses UK fintech Paymentology to power its Banking-as-a-Service growth and accelerate payments innovation in Australia. Paymentology, the global leader in next-generation card issuing and payment processing, today announced a landmark partnership with Constantinople, one of Australia's most ambitious fintech innovators. The collaboration marks Paymentology's official entry into the Australian market, underlining its commitment to advancing digital payments innovation across the Asia-Pacific region. The announcement was made during the Singapore FinTech Festival, held from 12 to 14 November, 2025, where industry leaders from around the world gathered to explore the future of financial services. Constantinople will leverage Paymentology's advanced global payments platform to deliver a seamless end-to-end payment experience, including card issuing, processing, and digital wallet integration, across its growing network of financial institution clients. Founded in Sydney, Constantinople is redefining Banking-as-a-Service (BaaS) in Australia by providing a modern software and operations platform that brings together both front-end digital banking infrastructure and back-office processes such as onboarding, compliance, fraud monitoring, and risk management. By positioning itself as "the AWS or Shopify for banks", the company enables financial institutions, particularly fintechs, regional and tier two and three banks, to focus on customer experience while outsourcing the complex aspects of banking operations. Its technology allows these institutions to operate at a fraction of traditional costs, freeing them to innovate more quickly and effectively. Through this partnership, Paymentology will power Constantinople's card issuance and transaction processing across both Mastercard and Visa schemes, ensuring a secure, flexible, and scalable payment experience for banks and their customers. The collaboration also incorporates Constantinople's core banking integration through 10x, as well as Apple Pay and Google Pay tokenisation, supported by dedicated BINs (Bank Identification Numbers) that underpin the company's customisable card programmes. Constantinople currently supports several leading Australian community banks and innovative Fintechs. Clients include Great Southern Bank, the nation's largest customer-owned bank with over 400,000 members, as well as Tyro, a leading payments provider focused on driving innovation for small businesses. With Paymentology's multi-cloud, multi-tenant architecture, Constantinople will benefit from marketing leading digital services, a powerful decision engine, enhanced scalability, global resilience, and real-time data, enabling faster card issuance, richer insights, and a more intelligent platform for sustainable growth. More than a technology provider, Paymentology acts as a strategic partner that is deeply invested in co-creation, foresight, and shared success, bringing a human, collaborative approach to every engagement. Its dedicated teams understand the nuances of Banking-as-a-Service models and what it takes to succeed in a highly competitive, regulated environment. The partnership also signifies Paymentology's formal expansion into the Australian market, where card adoption is projected to grow at double-digit rates over the next five years, driven by digital-first consumers and the increasing popularity of mobile and contactless payments. It represents a pivotal milestone in Constantinople's broader ambition to scale internationally, with Paymentology serving as a global payments partner capable of supporting that journey at scale. Di Challenor, Co-Founder of Constantinople, said, "Constantinople's mission is to give smaller banks and innovative fintechs access to the same leading-edge technology as big global banks. We do this by partnering with leaders in their field; partnering with Paymentology will allow us to launch new card programmes at pace, with the flexibility to tailor every element to our clients' unique needs. Paymentology's global reach ensures we can scale effortlessly beyond Australia." Paymentology CEO Jeff Parker (pictured right, with Keerthi Iyengar, COO of Constantinople, pictured left), "Our partnership with Constantinople marks an exciting new chapter as we expand into Australia's vibrant fintech and banking ecosystem. Beyond a technology partner, Paymentology is about thinking ahead, co-creating the future, and ensuring the growth and success of our clients. Working with Constantinople is particularly rewarding; their highly experienced leadership team brings a clear vision for modern, automated banking that perfectly aligns with our mission to empower next-generation financial institutions with the world's most advanced payment platform."
