    Lloyd O'Connor: Cybersecurity Is a Business Problem

    An executive spending a billion dollars a year on cyber protection asked if that guaranteed he would never be breached. Lloyd O'Connor's answer was no. Lloyd O'Connor helped pioneer Chase Quick Deposit and worked on cybersecurity at JPMorgan and Barclays before founding Aceiss.

    Dominic O'Kane: From Physics to Wall Street to FinancePy

    In 1994, Salomon Brothers' risk system crashed overnight because interest rates went negative, something the models said could never happen. Dominic O'Kane has spent 30 years closing the gap between textbook models and trading-floor reality. Dominic is a physicist turned Wall Street quant. He led quantitative research in Europe at Lehman Brothers, wrote the book on credit derivatives, and taught finance for nearly two decades. We talk about what a sell-side quant actually does, how correlation risk drove bonus pools before 2008, and why he built FinancePy, a free, open-source Python library for pricing derivatives. If you're a quant, a student, or on the buy side and want to check a price, this one is for you.

    Your Firm’s Most Valuable Data Is Trapped in Meetings

    Finance runs on meetings, but the knowledge from those meetings often has no real home. In this first episode of Stack-to-Street, Michael McLaughlin talks with Dmitry Grankin, founder of Vexa, about turning live meeting conversations into company knowledge that firms can control, search, and use inside their own workflows. For leaders in banking, credit, investing, and financial services, the question is simple: if meetings are where trust is built and decisions are made, who owns the data after the call ends?
