Top IoT Hardware and Development Companies in Europe

Your “Use Case“

Ideally, what you want is a one-stop shop that can provide a little tweaking and deliver IoT hardware +communications stack +software +apps. A key to a successful project is aftersales support. IoT projects rarely go right first time out.

How do you find the “right” IoT company?

A sweet spot between price, quality, support and speed. Speed is important. Longer timelines matter. Once your pet project falls out of management’s good graces, or a senior manager uses the word “restructuring,” whilst on a bathroom break… done. Kaput. Jira updates and dead air.

OK, the list. We can continue to chat later…

This list is segmented by location, why?

We’ve read a lot of posts saying Ireland is a big IoT development location because it is full of US tech multinationals that do IoT. This is mixing two distinct ideas. Multinationals are in Ireland for tax purposes, to hold a nearshore footprint in Europe and sell service contracts.

A small to mid-sized company looking for engineering services does not have the bargaining power to extract customization from Google, ABB, Siemens, Cisco or Microsoft. That is not how they play.

Risk analysis:

Your people should intuitively know how to use “it” (IoT operating systems, tools, data feeds, storage, etc.) without much training investment or foraging online for user documentation. If you can get information in your native language, better.

A black box in a remote location with a blinking red light is a problem. A service tech appearing on-site is worth gold. The next best thing is a remote tech with communication skills who can guide you through simple troubleshooting tests.

You can’t realistically airmail 20 boxes back to Suzy Q in China, with a smile emoji (You can try). On the flipside, if you can communicate exactly what you need done, Chinese manufacturers have the best turnaround times in the world.

“Vorsprung durch Technik”

I had a chat with a genuinely impartial friend (ChatGPT) about the topic of European IoT “solutions providers.” 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 for regular people.

There seems to be more segmentation in the UK and the Nordics. Manufacturers specialize in various areas and go deeper. If your industry goals are specific, vendors can often pass you forward to a contact that fits your use case. It works well: Say: industrial Greenhouses + IoT … expertise in both domains saves time, because the vendor already speaks “your language.”

Shop around – it will bring you value and an ability to compare products, philosophies and support packages. This also brings advantages on the supplier side, because a lot of tech time is wasted in deprioritizing unachievable grand ambitions (in a polite way).

Eastern European Hotspots

Eastern Europe has some powerhouse destinations. Fast internet, outsourcing culture and strong IT literacy drives 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 and it’s pivotal position in the Baltics.

Romania is internationally focused; strong in agency + outsourcing. IoT is a tight fit, especially on the software side.

Mergers & Acquisitions

Smaller European countries tend to follow a trend. Niche startups get sucked up by bigger (global) players once they hit a certain critical mass and market share. Expansion potential within home markets is limited. Mergers, or selling your place in the supply chain and network contacts to global players (M&A), becomes a practical options for owners and VC investors. Know what “vendor lock-in” means. Think about it ahead of time. Your entire IoT stack could go night-night in one day. If you want good examples take a look at the e-bike sector.

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, lead generation game.

This tactic works in IT, where the aftersales process is remote, but is more tricky with physical devices and on-site installation. It is always good to read the fine print before you buy “full solutions” online for “real world” project.

Two Caveats

For the novice planting a hardware flag in one of the global players: A solid part of our business comes from clients who went first to one of the household brands. Eventually frustration sets in, with upsell, “pass the parcel” meeting after meeting, hidden subscription fees, no fix for the “solution” once it is delivered to site, plus vendor lock-in tactics with data and platforms.

We know why this is; sales has no accountability to delivery and neither have strong connections with internal warranty and repair teams. They say: Trust Us. We can throw a lot of resources at it. Ultimately you pay for resource inputs – GIGO.

How do IoT contracts get made?

Many contracts for IoT come via a conversation between a software house (IT, IoT, OT, IIoT…what’s the difference?). Software vendors can live in a financially rewarding delusion bubble that software is at the core of 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 reality.

“Fake it till you make it” business practices give IoT development a bad name in industrial settings. When time is money and your current success rate is 1 in 4, that is a bad gamble for 75% of companies.

Industrial sensors have been in use for over 200 years, at this point. Implementing a secure, robust product is an eminently practical undertaking. But it is a skillset which must include practical thinking, working at heights and depths, electrical (grid) knowledge and core radio-telephony skills. Caveat Emptor.
