Top IoT Hardware and Development Companies in Europe

You are looking for the sweet spot between price, quality, speed and aftersales support. Speed is important. Longer timelines mean higher cost. Once your pet project falls out of management’s good graces, that’s it, done, kaput.

One of the keys to a sucessful project is aftersales support. You do not want a black box in a remote location with a blinking red light.

Context is key (Your use case matters)

We’ve read a lot of posts saying Ireland is a big IoT development location because it is loaded with US tech multinationals that do IoT (correlation, not causation). This is “cart before the horse thinking.” Multinationals are in Ireland for tax purposes, to hold a nearshore footprint in Europe and sell service contracts.

A mid sized company looking for IoT hardware or project work does not have the bargaining power to extract customization from Google or Microsoft. The local sales guy can’t make anything happen either, no matter how many promises they make. OK, the list first, we can continue this conversation later.

Ideally, what you are looking for is a one-stop shop that can provide a little tweaking, but deliver IoT hardware (and communications stack, plus software or apps) in a reasonable timeline to meet your (usually immediate or short term) project goals. Good communication skills are powerful tools when you are not completely sure how to get it done, or what constitutes the “definition of done.”

I had a chat with a genuinely impartial friend about this topic. He recommended German engineering, because they “treat hardware like engineering, not marketing.” Germans culturally look at the detail of hardware engineering differently to other European countries, possibly due to “mittlestand” or Germany’s Fraunhofer network. There is an inordinate Germanic pride in designing tactile, functional, effectiveness.

There seems to be more segmentation in the UK and the Nordics. Manufacturers specialize in various areas and go deeper, meaning that if your industry needs are specific, vendors in those locations can pass you forward to a contact tht fits you.

Eastern Europe has some powerhouse destinations, combining fast internet infrastructure, outsourcing and strong IT literacy, driving an innovation trend. The Polish education system is a hidden force, as is the high potential afforded by Poland’s close connection to both Ukraine and Germany. Romania is internationally focused; strong in agency + outsourcing, so the IoT fit is tight, especially on the software side.

Smaller European countries tend to follow a similar trend. Niche startups get sucked up by bigger (global) players once they hit a certain critical mass and market share. Expansion potential within the home market is limited. Mergers or buyouts become more practical options for owners and investors.

Another topic of interest is a familiar move of Ukrainian developers to build attractive web sites, ostensibly in “high value” European locations (distributed global teams), staffed by Ukrainians in Ukraine, or displaced Ukrainians worldwide. Indian development houses are adept at the same, perfectly legitimate, game. It works in IT, where the aftersales process is remote, but is much more tricky with physical devices and on-site installation. The idea is to charge “local prices” for outsourced work. Another benefit is using multiple sites in search engines as a lead generation funnel. It is always good to read the fine print.

Two Caveats

For the novice planting a hardware flag in one of the global players: A significant part of our business comes from clients who went first to one of the household brands, eventually getting frustrated with upsell, “pass the parcel” meeting after meeting, no fix for the “solution” once it was delivered to site and vendor lock-in tactics. We know exactly why this is; sales has no accountability to delivery. The globals might say: We can throw more resources at it. Ultimately you will pay for resource inputs – GIGO.

Many contracts for IoT come via a conversation between a software house (IT, IoT, …what is the difference?) and clients who are not literate in the nuances of real world deployment. Software vendors can live in a delusion bubble that software is the core to IoT. In much the same way that martial artists believed a good “Kiai” and some clean white pyjamas were enough before MMA fixed the frame. Some sell “solutions” which read perfectly on desktop or mobile, but cannot be applied in real world settings.

These practices give IoT development a bad name in industrial settings, where time is real money. Industrial sensors have been in use for over 200 years, at this point. Implementing a secure, robust, solution, from the hardware and software side, is an eminently practical undertaking. But it is a skillset which must include practical thinking, working at heights and depths, electrical knowledge and core radio-telephony skills. Caveat Emptor.
