Chris Walker is the founder of Refine Labs and Passetto, widely recognized as a leading voice in modern B2B go-to-market strategy. An engineer-turned-marketer, he built Refine Labs from his living room into an 8-figure demand generation agency, pioneered the 'dark social' concept in B2B, and hosted the top-ranked B2B Revenue Vitals podcast. He has since exited Refine Labs and shifted focus to ENCODED, a neuroscience-backed human performance company, while leaving behind a generation of marketers who rethought how buyers actually buy.
Kieran Flanagan is the Chief Marketing Officer at Zapier and one of the most influential voices in B2B marketing. A former software engineer turned marketing leader, he spent nearly a decade at HubSpot building its international marketing engine - growing the Dublin office from 12 to 1,000+ employees. Today he co-hosts the 'Marketing Against the Grain' podcast with HubSpot CMO Kipp Bodnar, publishes 'The AI Marketing Generalist' newsletter on Substack, and invests as a Sequoia Scout. He is widely credited with pioneering the B2B creator approach to marketing and is an outspoken champion of AI-driven marketing transformation.
