Geniusin. Experts in Electronics-led Prototype Development
YOU BRING THE IDEA. WE BUILD THE DEVICE.
Welcome to Geniusin — home of concept-to-prototype electronics engineering and development. We help funded startups and retired or early-retired innovators turn early-stage ideas into fully working electronic products. From initial concept to reliable, tested prototype, we design, build, debug, and validate the electronics properly — ensuring sound technical decisions at every stage.
Our work is led by senior British engineers with over 40 years of hands-on experience across research, development, and commercial innovation. Whether you’re preparing for investors or finally ready to build something you’ve had in mind for years, we focus on practical electronics development designed for long-term use, reliability, and real-world deployment.
If you’re serious about building a real product — not just concepts on paper — you’re in the right place.
The Gap Between Concept and Reality
IDEAS DON’T FAIL BECAUSE THEY ARE BAD.
Most great ideas fail because they are never started seriously – they stall between concept and reality. In electronics, most ideas die somewhere between the sketch and the circuit board. Poor design decisions, unreliable prototypes, and a lack of experienced engineering judgement mean many ideas never make it past the early stages.
Geniusin exists to bridge that gap.
The Geniusin Experience
OUR PROMISE. VALUE. OUR EXPERTISE.
When an idea matters, it deserves to be built properly. That means electronics that can be tested, demonstrated, relied upon, and taken seriously — by investors, partners, and manufacturers alike.
Geniusin is a close-knit network of electronics and engineering specialists, assembled as needed, with Paul Tombs leading every project. There is no hand-off to junior teams and no black-box development. Everything we do is built around one scarce asset: sound judgement — knowing what matters, what doesn’t, and how to move from idea to something that genuinely works.
Our decisions are made with long-term reliability, manufacturability, and real-world use in mind — not just getting something to work once.
If you’re serious about building something real, we’re here to engineer it properly.
Important Disclaimer
NDA-FIRST. CONFIDENTIAL BY DEFAULT.
Much of the work we do is confidential by nature. Early ideas, unpublished products, and commercially sensitive designs are treated with discretion as standard. We’re happy to put a non-disclosure agreement in place before any detailed information is shared, and we never assume that early concepts are “safe” to talk about casually. Most of our best work never appears publicly — by design.
Who we work with
STARTUPS WITH FUNDING
You have a commercial idea. You need hardware that works.
If you’re a funded startup, you’re not exploring a concept for interest’s sake. You’re under pressure to show progress — to investors, partners, and early customers.
What you need is a prototype that works reliably and reflects sound engineering judgement. Not a report. Something tangible.
Many startups come to Geniusin after a false start: a prototype that behaves inconsistently, outsourced work that didn’t hold up, or uncertainty about whether the electronics design is actually viable.
This is where Idea Validation & Design Review is often the right place to begin — a structured way to sense-check the design, identify risks early, and avoid committing time and budget in the wrong direction.
Once the foundations are clear, Geniusin supports startups through Idea to Prototype — designing, building, debugging, and validating electronics that can be demonstrated with confidence and taken seriously by external stakeholders.
Geniusin works best with startups that:
- Have funding allocated
- Have a clear product vision or problem to solve
- Value engineering done properly, not rushed
Work is led directly by Paul, with decisions made around reliability, manufacturability, and long-term use — not just speed
RETIRED AND EARLY-RETIRED INNOVATORS
You finally have the time. Now it’s time to build it properly.
Many people carry an idea for years — often born out of deep industry experience. A tool that should exist. A device that would have made work easier. A system that never quite got built.
What’s usually missing isn’t insight or motivation — it’s a trusted way to turn that knowledge into working electronics.
You don’t need to learn electronics from scratch. You need someone who can translate your thinking into a real device.
For some, the right starting point is Idea Validation & Design Review — a calm, experienced assessment of whether the idea is technically viable, how complex it really is, and what a sensible first step would look like.
From there, Geniusin can take the idea forward through Idea to Prototype, building something tangible you can test, refine, and finally see working.
This work is collaborative and unhurried.
You bring the idea and the experience.
Geniusin brings the electronics judgement.
If the idea matters to you, it will be taken seriously here.
