Prototyping
From CAD to a part in your hands. Functional prototypes, jigs, and fixtures — built to spec and iterated fast.
POC → Low-volume manufacturing
Gelco turns a working POC into dependable low-volume production — through fast prototyping, a costed and version-controlled BOM, and a supply chain we organise end to end. The agility of a small team, the rigor of an experienced one.

01 — What we do
Four capabilities that carry a design from a part in your hand to a run out the door. Pick the ones you need, or hand us the whole bridge.
From CAD to a part in your hands. Functional prototypes, jigs, and fixtures — built to spec and iterated fast.
Repeatable runs from a handful to a few hundred units — consistent quality without tooling up for mass production.
A bill of materials you can trust — costed, version-controlled, and ready for procurement at any scale.
Sourcing, vendor vetting, and logistics handled end to end — so your bench time goes into the product.
02 — Why Gelco
That gap is our entire focus. We've spent 10+ years on both sides of it — inside multinationals where process is everything, and inside startups where speed decides survival.
Gelco brings both: the discipline of an established manufacturer, delivered by a small team that actually answers the phone. Our production floor scales with you — from a 2 m² bench for early builds to 300 m² for a full low-volume run. The same people see it through, from first prototype to final shipment.

03 — Process
A clear path with no hand-offs to strangers. You see the same faces at every stage.
We turn your concept or POC into functional, testable parts — fast iterations in real materials.
We harden the design for manufacture: tolerances, materials, cost, and assembly all dialled in.
We cost the bill of materials, vet vendors, and lock a supply chain you can rely on.
We run your low-volume production with consistent QC and ship finished, inspected units.
04 — In their words
"Working with Gelco felt like adding a senior manufacturing team overnight — without the overhead. They sweat the details we couldn't get to."
Tamas Babel
Founder · Ongo Vision
"Gelco took our sensor from a fragile lab rig to a hundred field-ready units in under four months. They caught supply problems we didn't even know to look for."
Dr. Dana Reyes*
Hardware Lead · WaterScope
05 — Start your project
Whether you're staring at a working POC or somewhere mid-development, send the shape of the problem. You'll hear back from a real engineer, not a sales funnel.
