Turning data into actionable insights for engineering and sports organisations.

About

Hi, I’m Dan — founder of Acorn Four.

I started this company to build practical AI tools that bridge the gap between theory and impact.

My focus is on delivering elegant, user-first solutions that solve problems and provide real value—not just flashy or over complicated systems.

I hold an EngD in predictive maintenance, where I applied machine learning and sensor fusion to monitor abrasive waterjet cutting systems (published in a peer-reviewed journal), along with a Master’s in materials engineering.

In recent years, I’ve built six courses, launched several AI products, and worked with Tetra Tech RPS on automation tools that cut 210 days of work to 24 hours, forecasting sewage overflows, simulation modeling, and computer vision for asset inspection.
