Marc Massar has spent over two decades at the intersection of technology and business, helping banks, payments firms, and regulators run faster without falling over. He’s held senior leadership roles across the globe, including at JPMorgan, HSBC, and Worldpay, and now advises clients on payments, operating models and “outcome-based frameworks” that keep executives both intrigued and slightly nervous.

Beyond boardrooms, Marc’s curiosity extends from Victorian infrastructure to generative AI, fueling his research, consulting, and podcasting. A lifelong tinkerer, he restores orchards and ponds, experiments with glass and hobby paints, and will happily debate GPU energy curves or the virtues of a Japanese vegetable cleaver.

That eclectic mix powers The Nostalgic Nerds Podcast, which he co-hosts with Renee, where personal stories meet tech history, and every gadget, standard, or theme park ride has a story worth telling.

Renee is a global keynote speaker and founder of The Storyteller’s Circle, a community that equips professionals to command any room with confidence and clarity. Formerly, Principal Analyst for Risk Management at Verdantix, she led thought-leadership on Governance, Risk & Compliance (GRC) and Enterprise Risk Management (ERM).
Before Verdantix, Renee spent a decade at Forrester Research as the firm’s lead analyst for risk, audit, and sustainability. There she pioneered landmark research on climate-risk, nature-based solutions, and carbon-accounting platforms—work that still shapes best practices. 
With a vibrant social-media presence and a calendar filled with webinars, workshops, and conference keynotes, Renee empowers audiences to navigate risk, champion sustainability, and communicate with impact.
