LONDON, UK - Today we announced a partnership with Tweezr, a provider of deterministic AI for legacy system understanding. The partnership is designed to reduce one of the biggest barriers to core transformation: the lack of reliable, system level understanding of complex legacy estates.
As banks modernize toward flexible, real time platforms like 10x Banking, gaining visibility into legacy environments becomes critical. Decades of customization, undocumented business logic, and tightly coupled dependencies make it difficult to fully understand how systems behave, increasing risk and slowing migration efforts away from monolithic cores.
Through this partnership, 10x Banking customers can use Tweezr as a migration tool to analyze legacy systems directly from source code, uncovering hidden business rules, technical dependencies, and data flows. Tweezr, winner of Best of Show at FinovateEurope 2026, creates a trusted, explainable view of the system. This allows teams to assess impact, validate assumptions, and map critical functionality with confidence before and during migration to the 10x Banking platform.
By combining this deterministic system understanding with 10x Banking’s proven migration tooling and delivery approach, banks can move away from legacy with greater precision, reduced risk, and improved execution speed.
“Modernizing core banking systems isn’t just a technology shift, it’s a trust problem. Banks need to understand exactly how their systems behave before they can safely change them. Regulators expect banking leaders to have personal responsibility to ensure controls are in place to avoid major negative impact. Tweezr provides a deterministic, code based view of legacy systems, removing guesswork and enabling teams to move forward with clarity and control as they migrate to platforms like 10x Banking.”
Ohad Kotler, CEO and Co Founder at Tweezr
"Core migration anxiety is one of the biggest barriers to transformation, particularly when leaders lack certainty about how legacy systems will behave during change. Tweezr’s deterministic insight helps remove that uncertainty, giving banks greater confidence and control on the path to migration. This partnership strengthens our de risked approach, enabling banks to move off legacy and onto the 10x Banking platform with predictability and assurance.”
