About
ProtoGT is a hands-on engineering company in Sheffield. We keep design, development and build close together, so the people you speak to are the people doing the work.
Read MoreWhy ProtoGT?
Our independent streamlined structure means faster decisions, clearer communication and more of your budget spent on the engineering, not layers of management.
We build custom prototypes that are engineered for long-term performance. Every part is stress-tested, every design reviewed, and every system validated before delivery.
Mechanical, electronic and software engineering under one roof, with quick replies and actual progress
From early concept to final install, we keep engineering practical and communication direct. You always speak to the engineers doing the work.
