Summary
👤
Senior🎓
Top SchoolBrett Levenson is a founder and seasoned engineering leader with 11+ years building large-scale, reliable ML and distributed systems for platforms like Meta and Apple. He led Cross-Meta Integrity as a Distinguished Engineer, focusing on making enforcement systems auditable, testable, and aligned with written policy—work that directly inspired his startup, Moonbounce, which translates plain-English policies into real-time, executable AI guardrails. At Moonbounce he now runs an AI control engine processing tens of millions of content pieces daily for customers including Tinder and Civit.ai, backed by a $12M raise. His background spans product-focused startups to enterprise R&D, with a track record of reducing costs and improving human-in-the-loop labeling through optimization and RL. Based in Oakland and trained in mathematics at Columbia, he combines deep systems thinking with a practical obsession for verification and reproducibility in inherently non-deterministic ML systems. An underappreciated strength: he designs infrastructure with the same attention to explainability that regulators and product teams demand.
