After helping scale adtech, modernize a flower business and turn motherhood into an operating credential, Christina Cubeta is asking a harder question: what should marketing preserve when machines begin making the buys?

From Windows 3.0 migrations to Ford's digital showroom and Viant's AI-era advertising platform, his work keeps returning to one stubborn question: did the marketing actually work?
Matthew Goldhill is the founder and CEO of Picnic, a London-born adtech company that pioneered 'social display' advertising - Stories, Posts and Carousels dropped mid-article on Google AMP pages, a format that didn't exist before he built it. He left AppNexus at 25 to start the company, bootstrapped it for years, delivered 600+ campaigns for brands like EE, L'Oreal and Amazon, then raised £1m in 2023 and moved to New York to crack the US market. He builds user-first, low-carbon ad products and is unusually candid about the near-disasters along the way.
