Built from 20 years inside the problem.
Commonrocket didn't start with a business plan. It started with a pattern we kept seeing — brilliant founders, complex hardware, and a mechanical engineering gap that kept costing them time, money, and momentum.
The Founding Story
Why we Built commrocket
Over 20 years across defence, aerospace, electric vehicles, green hydrogen, and agri-tech, I worked in almost every role that exists in mechanical product development — solo engineer, design lead, manufacturing head, and full product development team manager.
Across all of it, I kept seeing the same thing: founders with genuinely great ideas and strong technical skills in software or electronics, hitting a wall when it came to the mechanical side. Not because they weren't capable — but because mechanical engineering is a different discipline, with its own ecosystem, its own vendors, its own failure modes.
Hiring a right full-time mechanical engineer is expensive and slow. Using a freelancer gets you drawings, but not judgement. Going to a traditional consultancy costs more than most early-stage startups can justify, and the pace doesn't match how founders actually work.
Common Rocket is the answer I wish existed when I was on the other side of those conversations. A mechanical engineering partner that works the way a startup works — fast, flexible, accountable, and deeply embedded in your team until the product is made.
"I've seen hardware products fail not because the idea was wrong — but because nobody owned the mechanical. We built Commonrocket to make sure that doesn't happen to your team."

What we stand for
Accountability over advice
We don't just consult and walk away. When we take on a mechanical scope, we own it — through design, prototyping, and manufacturing. The drawings don't end the engagement.
We price, communicate, and work in a way that fits how startups actually operate — not how traditional engineering consultancies do. Speed, clarity, and flexibility matter.
Founders first
HOW WE OPERATE
Our experience spans eight high-stakes industries where mechanical engineering failures have real consequences. That rigour is what we bring to every startup engagement.
Ecosystem over ego
Rigour without bureaucracy
We're not here to do everything in-house. We're here to activate the right vendors, partners, and specialists at the right time — on your behalf.
We bring aerospace and defence-grade engineering discipline to every project — but without the overhead, the lengthy processes, or the enterprise pricing.
