Who we are

First Chrome V8

Do you remember when your browser crashed because you had opened one too many tabs?

The founders from Toit fixed that by building the V8 JavaScript engine for Google Chrome.

Then Dart

Or do you remember when you had to write your app in 3 different languages so it would work on mobile, desktop, and web?

The founders from Toit fixed that by creating the Dart language, the fastest-growing programming language in 2019 because of its adoption by Flutter, Google’s UI toolkit for building applications.

And now Toit

Strong from their virtual machine and programming languages successes, these engineers - and the rest of the ever-growing Toit team - have now built Toit, a cloud-managed container platform for IoT.

So now developers can say “Remember when we had to send the whole image of our firmware over-the-air at once?” or “Remember when we could brick devices with just one typo in our code?”

What we built

The Toit team has built a software platform that lets you run containers on very small MCUs with as little as 500 KB of RAM - and in particular on ESP32 microcontrollers because we love their price/performance benefits.

With this platform, you can update the firmware layer and all the apps that run on it so that you will never need to flash an entire firmware image to a device anymore.

The apps you run in your on-device containers work continuously and independently from each other at all times, even when you update the firmware or transfer your data to the cloud, and even when your devices are offline - so you can run devices on batteries for a very long time.

For this to work on microcontrollers, Toit brings you a new high-level language designed for IoT. You will use it to build apps that communicate with the hardware to generate data. Transfer of the data to the cloud is handled out of the box using the Toit API.

Finally, the team built an easy-to-use cloud-based management platform that takes care of updating your devices, visualizing your fleet health, and much more.


So when you sign up for Toit, you can start using our software on your own microcontroller-based hardware.

Our extensive technical documentation guides you from device provisioning with the Toit firmware, to writing apps with our high-level language, to deploying them over-the-air on any device from your fleet.


You can also always ask for help from our engineering team. We are proud of what we have built, and we are curious about what you want to do.
