You bring the idea. We build the device
From concept to working prototype – Electronics designed, built, debugged and tested for you by senior engineers with over 40 years of hands-on experience in research, development and commercial innovation.
Practical electronics development and engineering for funded startups and retired innovators.
If you’re serious about building a real product – not just concepts on paper – you’re in the right place.
Don’t let your idea stall
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.
Who we work with
Startups with Funding
You have a commercial idea and the funding to explore it.
You need a prototype that shows investors, partners and early customers you aren’t just theorising.
We can help and design the electronics, firmware and hardware that proof-out your concept.
Retired and Early-Retired Innovators
You’ve spent a career knowing exactly what tool, device or system should exist – but never had the time to make it real. Now you do.
We can help you turn decades of your insight into a tangible electronic product.
Core services
These two services work best together, but they don’t have to. Design validation provides clarity — a grounded understanding of what’s viable and what isn’t — while Idea → Prototype creates momentum by turning that clarity into something tangible. Both are designed to reduce risk, increase confidence, and help good ideas survive first contact with reality.
Why work with us
When you work with us, you work directly with Paul — backed by a lifetime of engineering experience.
Paul is our Senior Electronics Specialist and founder of Geniusin. He has spent more than 40 years designing electronics, leading R&D teams, and helping ideas become reliable, working systems. His experience spans defence, retail intelligence, and consumer devices, and includes founding and leading technology businesses as well as hands-on engineering work.
He previously held the role of Managing and Technical Director at Synovate Retail Performance, where he led the development and large-scale deployment of electronic systems across multiple countries. During this time, he was recognised as one of the top 0.5% of UK business leaders by Who’s Who of Britain’s Business Elite.
Today, Paul focuses on what he has always valued most: working directly with founders and innovators to design, build, debug, and validate electronic prototypes. He is a senior electronics specialist, a long-standing member of the IEEE, and someone who cares deeply about building things properly.
Our portfolio
Much of our work is covered by non-disclosure agreements and cannot be shared publicly. This is typical of the projects we’re involved in — particularly early-stage ideas, commercially sensitive products, and defence-related work.
The examples shown here illustrate the type of problems we’re often asked to solve and the outcomes achieved, rather than the full breadth of our experience.
If it’s helpful, we’re always happy to talk more openly during a discovery call, where context can be shared appropriately and confidentiality arrangements can be put in place.
Confidential retail electronics project
A DIY product range was undergoing frequent rebranding, but short trial periods and low sales volumes made shelf performance difficult to evaluate. Sales data alone could not separate packaging impact from external factors such as footfall, location, or weather.
A discreet, battery-powered sensing system was developed to measure customer footfall and dwell time at the display, with data analysed alongside sales and environmental variables across successive packaging iterations.
The result was a reliable way to normalise shelf-level performance and calculate conversion rates — enabling design decisions to be based on evidence rather than assumption.
Confidential electronics design project
A production electronics module was experiencing high failure rates during temperature cycling, leading to scrapped units and delayed deliveries.
We audited the design, identified a tolerance-sensitive switching issue, and implemented a simple stabilisation fix.
The result was near-100% production yield, reduced waste, improved reliability, and restored delivery timelines — without a full redesign.
Contact us
If you have an idea you’re considering, or an existing product that needs a second look, we’re happy to have an initial conversation. Often, a short discussion is enough to clarify feasibility, surface potential risks, and identify sensible next steps. There’s no obligation — just practical engineering insight to help you make an informed decision.
