FinovateFall Best of Show winner Tweezr celebrates completing a hat trick of BoS wins and shares the background behind the technology.

Host Greg Palmer sits down with Ohad Kotler, CEO and co-founder of Tweezr, fresh off the company's third Best of Show win—a remarkable hat trick spanning FinovateEurope 2025, FinovateEurope 2026, and now FinovateFall 2026 in New York. Ohad shares the origin story behind Tweezr, rooted in his own frustrating experience as a head of product at a large European bank, where a seemingly simple feature request for joint accounts turned into a year-long ordeal because only one engineer truly understood the legacy codebase. That pain point inspired him to build Tweezr: a platform that creates a "digital twin" of legacy systems using deterministic, formal code analysis to build a knowledge layer, giving developers, product managers, and AI agents expert-level, traceable answers about how their core systems actually work.

The conversation dives into how Tweezr's platform has evolved over the past 18 months, growing from a code-based knowledge layer into a tool capable of driving end-to-end software development lifecycle transformation—even enabling changes to be deployed directly onto mainframe and core systems. Ohad also reflects on the timing and challenges of expanding into the U.S. market, candidly noting the personal sacrifice of traveling with a four-month-old baby at home, balanced against the clear business opportunity of tapping into American financial institutions. He offers a revealing comparison between European and U.S. banking relationships with technology, observing that many U.S. regional and community banks have outsourced their technology stack to core providers like FIS, Fiserv, and Jack Henry, creating a sense of detachment and "lock-in" that differs sharply from the tightly coupled technology ownership common among European banks.

The episode closes on a forward-looking note, with Ohad challenging the common assumption that banks must wait for a full system migration before modernizing. Instead, he argues that institutions can achieve the "future of banking" today by gaining control and understanding of their existing systems, without the years-long disruption of a migration. Looking ahead, Ohad predicts a future where programming languages and underlying infrastructure—whether mainframe or distributed—become far less of a constraint, as natural language increasingly becomes the primary interface for understanding and evolving code.
