Matt Spiegel, Head of TrueAudience Growth Strategy at TransUnion, joins Corey and Joe to discuss what nearly nine years at the intersection of credit data and marketing technology has taught him about identity, measurement, and the limits of AI. Matt traces TransUnion's evolution from a credit bureau into a full-stack marketing data platform — covering the Neustar acquisition, the build-out of identity resolution, audience discovery, and marketing performance analytics — and explains why having all three capabilities sitting on a common dataset is what makes the offering different. The conversation tackles the cookie deprecation reality check, the ongoing challenge marketers face in demonstrating C-suite credibility through measurement, and why AI will transform the speed and economics of mixed media modeling long before it removes humans from the loop. Matt also offers a frank read on AI adoption.
