From Concept
to Production
We help design, prototype and manufacture electronic products, combining hardware, firmware, and mechanical engineering in one team.
The challenge
Product development has a problem
These are the reasons ZTPrototypes exists. Our structured development process is built to address each one directly.
"The project requires expertise across too many disciplines"
Your product needs electronics, firmware, mechanical design, and potentially cloud infrastructure. Coordinating separate specialists for each discipline introduces risk, delays, and fragmented accountability.
"There is no clear path from concept to a working product"
The product concept is sound, but without specialist electronics and firmware expertise it is difficult to assess what is technically achievable, what the key risks are, and where to begin.
"Previous development partners have failed to deliver"
Whether it was missed deadlines, poor communication, or a prototype that did not meet specification, the result is lost time and lost confidence. Starting again with the wrong partner is not an option.
"Investors and stakeholders need more than a presentation"
Funding decisions are made on evidence, not slide decks. A functional, demonstrable prototype provides the credibility required to secure investment and move to the next stage.
How It Works
A structured product development process
A proven, phased approach that reduces risk at every stage and keeps your project on track.
Why ZTPrototypes
Built for teams that need to move fast
We combine the technical depth of a specialist engineering consultancy with the speed and flexibility that early-stage products demand.
Reduced Risk at Every Stage
Every engagement begins with a structured de-risking phase. It includes a full feasibility study and technical validation report before committing further resources, giving you the evidence to make informed investment decisions.
Weeks, Not Months
Initial prototypes are typically delivered within four to eight weeks. We maintain tight scope, short feedback cycles, and consistent momentum to ensure your project stays on schedule and on budget.
End-to-End Capability
Electronics, firmware, mechanical design, software and cloud infrastructure, all handled by one team. Fewer handoffs means fewer miscommunications and a final product where every layer works together as intended.

Our Clients
Who we work with
We partner with ambitious teams and individuals building next-generation products.
Hardware Startups
Pre-seed to Series A companies developing a new technology product. Typically working with limited engineering resource in-house and looking for a technical partner to take them from concept through to a manufacturable prototype.
Established Businesses
Companies adding electronics, IoT connectivity, or embedded intelligence to an existing or new product line. They have domain expertise in their market but need specialist electronics and software engineering support to execute.
Independent Founders
Solo founders and inventors with a strong product concept and the ambition to bring it to market. They need a reliable engineering partner who can translate their vision into a functional, testable, and fundable prototype.
Technical leadership
Meet the founder
Working directly with clients to turn complex ideas into robust, production-ready products.

Founder & Technical Lead
Electronic engineer with experience in low-power electronics, embedded firmware, and mixed-signal PCB design
"I started ZTPrototypes because I saw the same problem playing out over and over. Talented founders with genuinely good product ideas were getting stuck, either priced out by large development houses or let down by unreliable freelancers.
I wanted to build the consultancy I would have wanted to hire. One that's technically rigorous, transparent on cost and timeline, and structured to get early-stage products from concept to production without unnecessary complexity."
