In this episode of Momentum: Where FinTech Meets AI, Stan Altshuller sits down with Leonid Flek, Head of Commercial at Stream OS, to unpack how agentic AI is finally solving the most painful part of financial operations - everything that happens after a contract is signed and before revenue is realized.

They explore real-world use cases from data-driven companies, why traditional tools fail to handle complex agreements, and where AI truly adds value versus where human oversight still matters. If your finance or data teams are stuck in manual workflows, broken handoffs, and operational bottlenecks, this conversation cuts through the hype and shows how proactive AI agents can drive clarity, speed, and measurable outcomes.
