Marc Massar
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.
