All over Europe, we've witnessed a growing number of lean hardware companies popping up, trying to change the way you automate your home and appliances, keep track of your fitness, record memories, monitor air quality, lock doors and bikes, and about a million other things.

Hardware may or may not be the new software, depending on who you ask, but an increasing number of entrepreneurs are jumping into the hardware (+ software) space, thanks to the rising speed and flexibility of the manufacturing supply chain, and the decline in costs and risk.

It's one of the more interesting trends we're keeping track of here at Tech.eu, but it's quite a daunting task to keep track of so many projects and companies being started in such a wide range of European countries.

In an effort to start seeing the forest for the trees, we've put together a fairly comprehensive list, featuring 50 of the most exciting lean hardware startups in Europe we could find. Like other lists, I'm sure we've missed a few here and there, but hey, that's what the comment section is for.

Despite the numbering, note that the list below is in no particular order.
