Sean Mahoney has spent 25+ years doing one thing exceptionally well: turning technology into revenue. He has taken companies from $1M to $10M and from $10M to $100M in ARR, built and led sales teams ranging from 2 to 25+, and owned the go-to-market for companies across AI, data intelligence, enterprise SaaS, ad-tech, and programmatic media. What sets him apart is range — he has operated at every stage of the curve, from zero-to-one startups through to some of the largest technology platforms on the planet.
At Meta, he was a Group Director in Global Marketing Solutions through the company's 2012 IPO — leading 20+ sales professionals across Fortune 100 accounts and personally running Procter & Gamble, then Facebook's largest global partnership, which he grew from $3M to $100M in three and a half years. He finished in the top 1% of sales performance and earned the company's Horizon Award. At Yext, he took revenue from under $500K to $5M in a single year into the 2017 IPO; at Yahoo's BrightRoll, he scaled the programmatic business from $0 to $50M in two years by integrating the technology directly into client operations.
"Revenue follows the fundamentals — the right team, the right go-to-market, and the right partnerships. Get those three in order and growth compounds."— Sean Mahoney
More recently he's been the growth engine for AI-native companies. As Chief Growth Officer at Invisibly — the AI data company founded by Square/Block co-founder Jim McKelvey — he scaled revenue 10x, from $1M to over $10M — primarily through strategic partnerships — and worked hand in hand with product, engineering, and data science to bring AI-powered solutions like synthetic audiences and predictive modeling to market. Through his firm Galway Group and advisory roles at Rivr, Quintilian, and others, he now helps founders sharpen positioning, accelerate adoption, and get their go-to-market right — the same work he brings to GTMBench engagements.
