Top 31 IoT Companies in The World

It’s 2019, and one of the most important technological trends in history – the Internet of Things (IoT) – is gaining momentum. The world’s top IoT companies have begun developing intuitive technology and infrastructure that will change our everyday lives. Smart devices and sensors are no longer a party trick to impress guests and help us secure our homes while we’re away; we’ll soon live in a world where smart thermostats, buildings, and vehicles combine to create entire IoT-enabled cities.

To help you gain a better understanding of what’s in store, we’ve compiled an IoT company list of the top 30 players in this field. All of these pioneers are using Internet of Things components to create technology that we could previously only dream about. Read on to discover what the future of IoT has in store for us.

What companies are involved in the Internet of Things?

Experts estimate that there’ll be over 30 billion connected devices by 2020. IoT companies are linking everything from health devices and trucks to fridges and oil drills, and it’s making them millions of dollars; forecasters have estimated that the market will double in size to a staggering $520 billion (USD) by 2021.

Connected machines can now sense, observe, and measure the world around them, then communicate the collected data between each other with no intervention from humans. This means machines no longer have to bother with our inaccurate, subjective interpretations to make logical conclusions.

IoT-enabled businesses can collect accurate data in real time, run post-production analysis, and optimize their processes based on those findings. Companies involved in the Internet of Things have already recognized the value of automation and accurate data collection; now their competitors are taking notice, which is leading to an increase in market share and profitability.

What is IoT software?

The Internet of Things is a giant network of connected mechanical and digital devices that operate autonomously. This includes devices we wear, such as fitness trackers, as well as medical implants and chip sensors we embed in animals. Many of these devices use sensors to interpret information from the outside world, then share that information with other connected devices over the network.

IoT software allows all of this to happen. It enables machines to collect and share data, operates the (mostly) cloud-based platforms where that data is stored, and analyzes said data. IoT software can also use information from a range of devices to help identify its faults and improve its efficiency.

What is an IoT chip?

An IoT chip is a tiny electronic device embedded in smart objects and machines. It connects to wireless networks, sends and receives data, and generates commands. In reality, these chips use the same data circuits and technology we see in mobile devices, only without the human-friendly aspects, such as displays or user interfaces.

IoT chips are almost always connected so they can send and receive data automatically and in real time. Many companies use IoT devices as replacements for human-controlled systems in remote, hard-to-reach environments like offshore oil rigs or underwater developments. As such, most IoT chips are built for durability and longevity.

What is MEMS and NEMS?

MEMS and NEMS sensors enable IoT devices and applications worldwide and across industries. MEMS stands for microelectromechanical system, even though the term mainly refers to microdevices with tiny embedded systems that permit higher-level functionality.

There are several types of MEMS:

  • Micro-engines, which serve as highly compact energy sources;
  • Optical MEMS, which send optical signals;
  • Inertial sensors like accelerometers or gyroscopic sensors;
  • Fluidic MEMS, which are known for being particularly precise.

Fluidic MEMS, for example, are used both in high-end digital printing and in medical devices that measure blood sugar levels or medication dosages. The term NEMS, on the other hand, refers to nanoelectromechanical systems. These serve the same purpose as MEMS, but on a nano scale.

Compared to other similar sensors, MEMS and NEMS have proven more efficient, sensitive, and precise. The technology’s fail-safe performance in extreme conditions has made it vital for safety features like airbag activation and vehicle stability.

Who invented MEMS?

You might be surprised to learn how long ago this technology was conceived. American electrical engineer Harvey C. Nathanson (born October 22, 1936) invented the first device using microelectromechanical systems way back in 1965. It was similar to what we now use in cell phones and digital projectors, although obviously, the technology has improved markedly over the years.

Taking all this into account, we decided to research the world’s best IoT companies. We compared companies’ annual revenue, teams, innovations, and growth. Using that information, we eventually came up with a list of the top 100 IoT companies from all over the world. Comparing those businesses across industries, we narrowed the list down to the top 50 IoT companies, and eventually ended up with 31.

So, without further ado, here are the top IoT companies of 2018.
