Your partners in product development.

Riganelli Engineering is a full-service product engineering firm based in St. Catharines, Ontario. Founded by Marcus Riganelli, P.Eng., our team of engineers and technicians works together across engineering and prototyping to take products from concept through to production-ready reality. As licensed professional engineers, we provide focused engineering services on even the most challenging and critical projects.

We work with small to mid-sized product-based businesses - companies that have deep industry knowledge but don't have engineering capacity in-house. Our clients come to us when they need to develop a new product, improve an existing one, or move faster than they can on their own. Together, we've helped our clients generate millions of dollars in revenue from products we developed side by side.

We handle the full product development process - from initial research and feasibility through engineering, in-house prototyping, and launch support. Our capabilities span mechanical and electrical engineering, CNC machining, 3D printing, injection molding, sheet metal fabrication, electronics assembly, product certifications, photorealistic renders, technical documentation, manufacturing support, and more.

Our facility at 636 Welland Ave. in St. Catharines houses both an engineering office and a fully equipped prototyping shop under one roof. Engineers and technicians work side by side, so designs move directly from screen to shop floor for fast iteration, short feedback loops, and no waiting on outside vendors for the core of the work.

The majority of our work involves industrial equipment, machinery, and high-tech products that combine mechanical and electrical complexity. These are products that require real engineering, not just design, and where performance, reliability, and manufacturability all matter. We work across a wide range of industries, and can quickly get up to speed in your specific domain.
