Engineered Solutions
From Concept to Completion
We build functional engineering systems from the ground up. From concept sketches to finished working prototypes, we care about detail and deliver to spec. We believe in long-term partnerships, honest collaboration, and investing in engineering talent. Everything we build is designed to perform under real-world conditions.
Why ProtoGT?
We’re small, and that works in your favour
Being independent means we’re flexible, focused and easy to work with. No middle layers. No bloated process. Just proper engineering.
Built with care, made to last
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.
Quick replies. Clear answers. Actual progress.
You’ll always speak to the people doing the work. We keep comms tight and projects moving.
The whole process, kept simple
From early-stage concept to final system install, we keep engineering practical and communication clear. No fluff. No waste.
Less waste.
More useful.
Big firms call it sustainability. We just build carefully.
We started in our uni rooms, so we know how to use what we’ve got. We reuse materials, repurpose old parts and keep waste low by design. We build systems to last. If something breaks, it can be fixed. If it no longer fits, it can be adapted.
Sustainability starts with working smarter. We’re always looking for better ways to do that.
What Clients Say
