Rockstar🎓
Top SchoolJohn Rosendahl is a product and engineering leader with over a decade of experience building ad tech platforms, identity and addressability solutions, and revenue-driving exchange products. He has progressed from hands-on engineering and founding a startup to directing product at companies like Mediavine and Optable, guiding cross-functional teams through complex technical transformations. Comfortable spanning front-end, back-end, and data strategy, he’s contributed practical fixes and feature support to the widely used Prebid.js open-source project. Known for marrying privacy-compliant data strategies with pragmatic product roadmaps, he routinely turns technical constraints into commercial differentiation. Based in Denver, he combines deep ad stack expertise with a founder’s bias for shipping and measurable impact. An uncommon strength is his history of toggling between engineering bootstraps and strategic product leadership, enabling him to translate low-level technical tradeoffs into executive decisions.
