Summary
The video outlines how GFT, a global banking‑technology integrator, and Mambu, a cloud‑native composable core platform, have joined forces to replace legacy mainframe systems. Their joint offering combines Mambu’s standardized code base with GFT’s regulatory and implementation expertise, promising a less risky, faster migration path for banks worldwide.
Key data points include a pilot that delivered a full core migration for a UK bank in eight months—far shorter than the typical multi‑year timeline—and a cost structure that avoids the multi‑million‑dollar price tag of traditional projects. The partners have also built accelerators such as the “BankStart” digital‑bank launcher and a migration toolkit that automate infrastructure‑as‑code and compliance steps.
Quotes from the speakers highlight the partnership’s success: “We proved it doesn’t have to take years” and “Our composable architecture lets banks swap ecosystem components via APIs.” The collaboration now spans Europe and Latin America, serving over 260 customers on a single code base, and is already exploring AI‑driven use cases and fully managed services.
For the banking sector, the alliance signals a shift toward modular, API‑first cores that reduce time‑to‑market, lower capital expenditure, and enable rapid AI integration, giving incumbents a viable path to compete with fintech challengers.
