Sophie Buonassisi is SVP of Marketing at GTMfund and GTMnow, where she leads a 58,000+ subscriber newsletter and media brand at the intersection of go-to-market strategy, venture capital, and B2B SaaS. A criminology graduate turned growth marketer, she spent 4.5 years as the first GTM hire at Spiralyze before standing out from 400+ applicants to join GTMfund. She transformed the GTM Newsletter into GTMnow - a full media brand that includes the reacquired Sales Hacker podcast (622+ episodes), a private Inner Circle community, and editorial content reaching 50,000+ founders, GTM leaders, and investors globally.
April Dunford is the world's leading authority on B2B product positioning. A former VP of Marketing at seven venture-backed tech startups (collectively acquired for $2B+), she turned a career of accidental positioning wins into a methodology used by 300+ companies including Google, IBM, and Epic Games. Her book 'Obviously Awesome' (2019, updated 2026) has sold 100,000+ copies and redefined how tech companies think about market context. She consults, speaks, angel invests, and runs a newsletter and podcast under the 'Positioning with April Dunford' brand.
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.
