Jerry Duff
He went from buying the model to evolving it. That's the strongest endorsement we know.
Jerry was a client first. He worked with Critical Propulsion's founding team for years, across engagements, through fire drills, on the kind of delivery problems that expose whether a team is real or just well-staffed. He saw the model work. Then he decided to help evolve it.
As a Director at both a Big Four firm and a leading mid-tier professional services firm, Jerry built and shipped technology across Partnership Tax, Asset and Wealth Management, R&D Tax Credits, and multiple other tax subservice lines. He modernized legacy systems, stood up cloud-native architecture, and led high-performing engineering teams inside some of the largest professional services organizations in the world. He knows what enterprise delivery actually looks like: the governance, the guardrails, the politics, and he delivers anyway.
Jerry is an early adopter and evangelist for Cursor, and a hands-on builder in C#, SwiftUI, cloud architecture, and data platforms. He doesn't just follow the agentic AI space. He's in it. Deploying agents. Pressure-testing frameworks. Pushing the community forward. At the same time, he holds a pragmatic line on security and enterprise guardrails. New technology earns trust by proving it works inside real constraints, not by ignoring them.
Jerry is an advocate for developers and architects: the people who actually build the thing. At Critical Propulsion, he leads, coaches, and mentors our technology community: both the consultants delivering for clients and the clients themselves navigating the shift to AI-amplified teams. His job is making sure every engineer in our orbit gets better, faster, and more dangerous, with the right guardrails in place.
