Modernizing Financial Services to Cut Cost and Build Trust
Safeguard data, enable real-time payments and make Financial Services personal with AI.
Financial institutions can’t afford outdated systems that drain IT budgets, slow payments and increase exposure to outages, fraud and regulatory penalties. At Publicis Sapient, we help financial leaders break free from legacy platforms with AI-enabled modernization that’s fast, secure and compliant by design. Powered by Sapient Slingshot, we cut through complexity so you can focus on enabling real-time payments, automating compliance reporting, unifying customer data and delivering personalized banking experiences that build lasting trust.
What’s holding Financial Services back?
Technical debt locks budgets into maintenance, leaving little room for real-time payments, open banking or new digital products. Growth stalls when systems can’t keep pace with customer demand.
Evolving regulations like GDPR, DORA and Basel III drive up compliance costs. Legacy systems make it harder to adapt, increasing the risk of fines and slowing reporting cycles.
Outdated batch systems and siloed architectures expose financial firms to outages, breaches and fraud. Each incident carries multimillion-dollar risks in penalties, remediation and lost trust.
Consumers expect instant payments, personalized offers and seamless service across channels. Rigid, outdated platforms make it nearly impossible to deliver at speed and scale.

Client showcase: a leading international bank
The challenge
A leading international bank was weighed down by aging, tightly coupled core banking systems. The old codebase was costly to maintain, difficult to update and full of security risks. It also slowed the bank’s ability to launch new digital services quickly and limited reuse across applications. To serve millions of customers securely and efficiently, the bank needed to reduce technical debt, improve resilience and accelerate modernization.
The solution
Publicis Sapient deployed Sapient Slingshot, our AI-powered software development platform, to analyze and transform the legacy core banking code. With AI-driven automation and human-in-the-loop validation, Slingshot enabled the bank to:
- Automatically generate specifications and diagrams from legacy code
- Produce modern code directly from those specifications, reducing manual effort
- Eliminate security vulnerabilities in the generated code
- Create reusable templates for future modernization, supported by a context graph that kept business logic and patterns intact
This approach proved that AI could deliver a faster, safer and more scalable path to core banking transformation.
