The New Marketing Stack

Marketers are often drowning in tools, not doing marketing. Kieran Flanagan, SVP of Marketing, AI, and GTM at HubSpot, managing a 350-person team, proved that flipping this script drives real revenue. His AI-personalized email workflows delivered a 30% increase in sales meetings with equal or better close rates. On this episode of the Marketing Execution Podcast, we break down the exact workflows he built: a "Chief of Staff" AI agent that clusters Slack, meeting notes, and email into weekly action plans; a vibe-coded tool that extracts viral talking points from video transcripts mapped to the YouTube algorithm; and a research assistant that surfaces compelling stories for content in seconds. If you are a technical founder looking to scale GTM without bloated headcount, this episode is your operating manual.
