Rockstar🎓
Top SchoolJuan Lozano is a founder and technical leader with a decade of experience building production-grade machine learning systems and developer-facing AI products. As Co-founder & CTO of Mariana Minerals and former Head of Machine Learning at Kite (scaling the product to 500k MAUs), he has repeatedly taken teams and ML infrastructure from 0 to 1, then into production at scale. His work spans applied deep learning, program analysis for code intelligence, and ML-driven growth systems—he built Affirm’s first multi-armed bandit marketing engine and its initial ML underwriting tooling. A Stanford-trained computer scientist and physicist, Juan combines rigorous algorithmic foundations (from 3D reconstruction and variational mesh techniques) with product-minded execution and investor-facing technical storytelling. He’s equally comfortable recruiting and shaping teams as he is coding core models and systems, often translating research ideas into measurable business impact.
