Summary

Rockstar🎓
Top SchoolMark Freeman is a data reliability expert and early-stage operator who blends hands-on engineering with GTM leadership, currently serving as Head of DevRel and employee one at Gable. With an M.S. from Stanford Medicine focused on causal inference, he’s built production data pipelines, NLP-powered products, and data-quality engines that scaled to billions of records. He drove Gable’s go-to-market motion—generating 4,000+ leads and 300+ senior meetings—and co-authored O’Reilly’s Data Contracts, positioning a new category in the data market. As a LinkedIn Learning instructor and founder of On the Mark Data, he’s grown audiences of tens of thousands and taught 39k+ learners practical data engineering and quality practices. Unusually for an engineer, he spent three years on the business side closing enterprise deals and shaping product strategy, giving him rare fluency in both technical fixes and the boardroom buy-in needed to deploy them. He’s now focused on post-deployment AI evaluation in regulated environments, a problem he views as the highest-impact frontier for trustworthy AI.
