David Kim is an AI Product & Marketing Technologist with 7+ years of experience building martech tools and marketing automation pipelines. A full-stack engineer turned marketing technologist, David brings a builder's perspective to marketing infrastructure—he doesn't just evaluate tools, he understands how they work under the hood and how to make them work together. David's career path is unconventional in the marketing world. He started as a software engineer at two Y Combinator startups, where he built customer-facing products and internal tools. During his second startup, he was asked to "also handle marketing" when the team couldn't afford a dedicated marketer. This accidental entry into marketing revealed a gap he's been filling ever since: the disconnect between what marketing teams need and what engineering teams build. At his most recent startup, David architected a unified marketing data platform that connected 8 different tools through a single API layer, reducing data sync delays from hours to seconds and enabling real-time personalization across email, web, and mobile channels. This experience crystallized his conviction that the future of marketing technology isn't more tools—it's smarter integration through AI agents. At YOYA, David writes about the intersection of AI engineering and practical marketing execution. His articles focus on the technical architecture of modern AI marketing stacks, integration patterns, data pipeline design, and how to evaluate AI tools beyond marketing hype. He's particularly interested in how AI agents can replace the "integration tax"—the hidden cost of making multiple marketing tools work together. David is an active open-source contributor, maintains several popular npm packages for marketing data processing, and speaks regularly at MarTech Conference and API World. He holds a B.S. in Computer Science from MIT and an M.S. in Information Systems from Carnegie Mellon University. When not building marketing infrastructure, he's training for ultramarathons and experimenting with homebrew automation projects.
