Rockstar🎓
Top SchoolJames Villarrubia is a technical advisor and seasoned CTO-level leader with 11 years of experience delivering enterprise AI and cloud platforms that move beyond pilots into production at organizations ranging from NASA to venture-backed startups. He built MADI, one of NASA’s first enterprise generative AI platforms, co-authored NASA’s Responsible AI Policy, and drove portfolio-wide AI adoption and 99.9% platform reliability as a Global CTO for private equity-held companies. Known for stepping into high-stakes transformations, he combines deep technical chops in ML infrastructure, cloud, and agentic systems with pragmatic change management, governance, and operating-model design. His track record includes a 10x scale-up across 500+ hospitals in 30 days at CipherHealth and product-led exits and acquisitions in security and HR tech. An MIT Sloan MBA, Presidential Innovation Fellow, Lean Six Sigma Black Belt, and patent-holding inventor, he often works best as CTO, CPTO, or Chief AI Officer. Unusually for a systems-builder, he treats culture with the same rigor as code—believing organizational design is the primary determinant of AI success.
