Branches are quiet these days. Real action sits in APIs, real-time payment rails, AI models that catch fraud before a customer even blinks. Add ISO 20022 deadlines, open banking rules, neobanks nibbling at margins — that’s 2026 for you. Plenty of banks still run on cores built decades ago. Swapping them out without breaking anything? That’s the actual puzzle. Ten providers below are solving it, from heavyweight platforms to sharp regional players.
Why This Matters Now
Hiring a systems integrator and crossing fingers used to be enough. Not now.
- Regulatory reporting shifts across jurisdictions, sometimes every quarter
- Customers want banking apps that feel like fintech, not a relic from 2009
- Old cores still carry most global transaction volume
- AI fraud checks and accessibility testing? Baseline now, not extras
Trading desks feel this too. A platform health check works like an oil change — skip it long enough, and something expensive breaks.
Companies Worth Knowing
DXC Technology
Over 45 years in banking tech, and 17 of the top 20 global banks still rely on it. Its Hogan platform runs six of the top ten US banks and handles roughly two-thirds of US card transactions. CoreIgnite, DXC’s orchestration layer, exposes core banking through APIs for real-time integration. Banco Sabadell recently brought DXC in for AI-powered accessibility testing.

Endava
London-headquartered, Romania-rooted, built around payments and capital markets from day one. Endava modernized platforms for Raiffeisen Bank and leaned hard into embedded finance work across Europe. Cloud-native, iterative — no big-bang replacements here. Listed on the NYSE since 2018, the financial services arm has continued to grow.
EPAM Systems
Started in Belarus, headquartered in the US for years now. EPAM built a solid financial practice spanning core banking, wealth management, and regtech. Worked with Julius Baer on digital wealth platforms. Strong on design talent paired with deep engineering — useful when a bank wants a slicker app without destabilizing the back office.
Sopra Steria
French-headquartered, with Sopra Banking Software serving over 1,500 institutions worldwide. Platforms cover retail banking, leasing, and consumer finance across Europe, Africa, and Asia. Lately pushing into RegTech for Basel IV. A steady choice for mid-size European banks working with tighter budgets than the giants.
Synechron
New York-founded, financial services as a whole focus rather than a side project. Runs innovation labs dedicated to banking, insurance, and capital markets tech. Partnered with major investment banks on trading platform upgrades and blockchain settlement pilots. FinLabs experiments with generative AI for compliance paperwork — a niche bigger rivals still tend to skip.
LTIMindtree
India-headquartered, formed from the 2022 merger of Mindtree and L&T Infotech. Runs a sizeable banking practice across North America, Europe, and Asia-Pacific. Supported core banking transformations for regional Southeast Asian banks and built AI underwriting tools for lenders. Scale brings pricing leverage on large programs without losing domain specialists along the way.
Tietoevry
Finnish-Swedish, with deep Nordic banking roots running back decades. Built much of the digital backbone for Scandinavian retail banks. Specializes in payment processing, card systems, PSD2-aligned open banking APIs. Handled real-time payment rail rollouts where regulatory deadlines leave zero room for slippage.
Globant
Argentina-founded, listed on NYSE, growing fast across Latin America and the US. Worked with Santander on customer experience redesigns and digital onboarding. Strong on design thinking — engineers paired with behavioral researchers, untangling friction points in mobile banking journeys that bigger vendors often miss entirely.
Finastra
UK-headquartered, a software vendor rather than a consultancy. Supplies core banking, lending, and treasury software to thousands of institutions, including plenty of US community banks. The Fusion suite spans trade finance to retail lending origination. Partners with integrators like DXC for delivery — the engine, not the mechanic.
Persistent Systems
An India-based banking and insurance unit has grown through targeted acquisitions in data and AI. Built cloud migration roadmaps for mid-tier US banks, working closely with Salesforce and Azure. Tends to win on speed — timelines other consultancies quote in years sometimes compress down to months here.
Closing Thoughts
No single name fits every bank. Scale, region, legacy footprint, risk appetite — all of it shapes the right call. What links these ten: none treat financial services as just another line item. That focus tends to count for more than headcount once systems can’t afford downtime.
How to Pick the Right Provider
Skip the brand worship. A glossy case study means little if no one on the team has handled a mainframe migration under a regulator’s nose.
- Real banking depth, not generalist IT dabbling
- Comfort with KYC, AML, ISO 20022, across more than one jurisdiction
- An actual partner network — Temenos, Murex, Finastra, not just logos on a slide
- Flexible engagement: staff augmentation, managed services, full outsourcing
- Willingness to commit for years, because transformations don’t wrap in one quarter
Get this wrong, and a bank ends up stuck for years with a vendor that can’t scale past the pilot.
FAQ
Do small banks need the same providers as the giants? Not really. Regional names like Tietoevry or Sopra Steria often fit mid-size banks better.
Is modernizing the core always a full replacement? No. Many banks wrap legacy cores with APIs rather than rip them out.
How long does a core transformation usually take? Years, typically, depend on the scope and how tangled the existing systems are.
Are software vendors and consultancies the same thing? Not quite. Vendors like Finastra build the software; consultancies implement and maintain it.
What’s the biggest mistake banks make when picking a provider? Going by brand recognition instead of checking real regulatory and core-banking experience.
