There may be billions of IoT devices in use today, but the tooling around building (and updating) the software for them still leaves a lot to be desired. Esper, which today announced that it has raised a $30 million Series B round, builds the tools to enable developers and engineers to deploy and manage fleets of Android-based edge devices. The round was led by Scale Venture Partners, with participation from Madrona Venture Group, Root Ventures, Ubiquity Ventures and Haystack.
The company argues that there are thousands of device manufacturers who are building these kinds of devices on Android alone, but that scaling and managing these deployments comes with a lot of challenges. The core idea here is that Esper brings to device development the DevOps experience that software developers now expect. The company argues that its tools allow companies to forgo building their own internal DevOps teams and instead use its tooling to scale their Android-based IoT fleets for use cases that range from digital signage and kiosks to custom solutions in healthcare, retail, logistics and more.
“The pandemic has transformed industries like connected fitness, digital health, hospitality, and food delivery, further accelerating the adoption of intelligent edge devices. But with each new use case, better software automation is required," said Esper CEO and co-founder Yadhu Gopalan, who founded the company together with COO Shiv Sundar. "Esper’s mature cloud infrastructure incorporates the functionality cloud developers have come to expect, re-imagined for devices."

Mobile device management (MDM) isn't exactly a new thing, but the Esper team argues that these tools weren't created for this kind of use case. "MDMs are the solution now in the market. They are made for devices being brought into an environment," Gopalan said. "The DNA of these solutions is rooted in protecting the enterprise and to deploy applications to them in the network. Our customers are sending devices out into the wild. It’s an entirely different use case and model."
To address these challenges, Esper offers a range of tools and services that includes a full development stack for developers, cloud-based services for device management and hardware emulators to get started with building custom devices.
"Esper helped us launch our Fusion-connected fitness offering on three different types of hardware in less than six months," said Chris Merli, founder at Inspire Fitness. "Their full stack connected fitness Android platform helped us test our application on different hardware platforms, configure all our devices over the cloud, and manage our fleet exactly to our specifications. They gave us speed, Android expertise, and trust that our application would provide a delightful experience for our customers."
The company also offers solutions for running Android on older x86 Windows devices to extend the life of this hardware, too.
"We spent about a year and a half on building out the infrastructure," said Gopalan. "Definitely. That's the hard part and that's really creating a reliable, robust mechanism where customers can trust that the bits will flow to the devices. And you can also roll back if you need to."
Esper is working with hardware partners to launch devices that come with built-in Esper-support from the get-go.
Esper says it saw 70x revenue growth in the last year, an 8x growth in paying customers and a 15x growth in devices running Esper. Since we don't know the baseline, those numbers are meaningless, but the investors clearly believe that Esper is on to something. Current customers include the likes of CloudKitchens, Spire Health, Intelity, Ordermark, Inspire Fitness, RomTech and Uber.
