Jeff is the co-founder and CTO of Opus, a mobile-first training platform designed for the 70% of American workers who don't sit at a desk. He built Opus's AI-first engineering team from the ground up, including a translation system that achieves 95-99% accuracy across 100+ languages, and an AI Content Builder that runs 20x faster than legacy solutions. Opus serves brands like Smashburger, Blaze Pizza, VASA Fitness, Salt & Straw, and Big Chicken. Before Opus, Jeff was an Engineering Manager at Managed by Q, where he rose from software engineer to management in under a year. He is one of the most rigorous technical voices on what it actually takes to build AI products that work at scale. We first met Jeff in 2017, when Jeff was recruited on the UPenn campus to join Managed by Q. Dan introduced Jeff to Rachel Nemeth at Opus in 2020.
