Rebuilding the Foundation of Financial Operations with Ignacio Berardi, Co-Founder and CEO of Rexi

This week on Tech Can’t Save Us, host Paul David is joined by Ignacio Berardi, Co-Founder and CEO of Rexi, an AI-native financial operations platform rebuilding the infrastructure layer beneath modern fintech. Rexi automates reconciliation, accelerates financial close, and replaces fragile manual back-office workflows with intelligent agentic systems — building what Ignacio describes as the operating system for modern finance.

They discuss how the rapid proliferation of application-layer fintech providers has created a fragmented, modular financial stack in which money movement passes through multiple abstraction layers, making end-to-end transaction tracking increasingly difficult and resulting in systemic balance-sheet write-offs of one to two percent of total payment volume — a problem the Synapse collapse made viscerally real when over $160 million in user funds went unaccounted for overnight. Ignacio explains how Rexi approaches this as fundamentally a coordination problem: ingesting data files from disparate systems, parsing and standardising them with AI at speed, and deploying agents trained across the full portfolio of customer edge cases to investigate discrepancies and close out the long tail of exceptions that human teams routinely write off.

The conversation covers Rexi’s go-to-market approach — founder-led, in-person sales targeting operators rather than crowded enterprise conferences, with six-to-eight-week forward-deployed implementations designed to build trust inside critical financial infrastructure. With a seed round targeted for Q3 2026 and the team approaching 50k MRR, Ignacio explains why brand and relationships, not product features, will be the lasting competitive differentiator in an AI-commoditised market. He also shares hard-won leadership lessons drawn from Bain, Bitso, and Harvard Business School, and why no amount of prior experience truly prepares a founder for the consequential, real-time decisions of building a company from scratch.
