Jonathan Greene

Jonathan leads Marketing and AI at Proto. He has spent three decades working where new technology changes how audiences behave, and he tends to build the system rather than just recommend it: the data, automation, and AI tooling that let a lean marketing team operate at the scale of a much larger one. Most recently, Jonathan was Chief Marketing Officer at Scratch, the world’s largest free creative learning community, used by more than 160 million young people in 70+ languages. There he led a full brand repositioning, rebuilt lifecycle marketing across 1M+ subscriber profiles, and designed the AI systems behind the team’s executive briefings, meeting intelligence, and content pipelines. Before Scratch, he was SVP of Marketing at Techstars, running a 20-person global team across 2,000+ portfolio companies, and fractional CMO/COO of AI talent platform Pipeline Equity. Jonathan spent nine years at R/GA, where he built the Global Mobile & Social practice into a 60-person international team, led strategy for Google and Mastercard, and ran FutureVision, the agency’s global forecasting program drawing on 1,600+ contributors. Earlier, he led client services at Superfly for Apple, Lyft, and Citi, and built the first digital practice at Euro RSCG Devon Direct, where his work helped add 500K customers for Nextel and launched Network Solutions to 10M customers in 16 months. He started his career as the sixth employee at CDNOW in 1995. He publishes Adjacent, a trend intelligence newsletter with roots in FutureVision. A Hamilton College graduate, former swimmer, and avid cyclist, he lives in Katonah, NY.
