Cloud-native application monitoring and debugging startup Lumigo Ltd. has raised what it says is the largest-ever investment in serverless computing: a $29 million Series A round of funding.

RedLine Capital led the round with participation from Wing Venture Capital Vertex Ventures U.S. and existing investors Pitango First, Grove Ventures and Meron Capital, bringing its total amount raised to date to $37 million.

Lumigo provides monitoring and debugging tools for applications that run in so-called serverless environments in Amazon Web Services. Serverless computing is a popular new execution model in which public cloud providers dynamically allocate resources whenever a piece of code is executed and only charge for the resources used. With serverless, companies can build and run applications without worrying about the infrastructure they run on, as all of the management is handled by their cloud provider.

Serverless is advantageous in many ways, but those automated environments are becoming increasingly complex, with most companies using a mix of serverless components, software containers and managed services. Because of this complexity, it can be difficult to pinpoint what the problem is in the event an application breaks or slows down.

This is the problem Lumigo is trying to solve with its agentless distributed tracing tools that allow developers to visualize every request in their cloud-native apps as it moves from service to service. The tools provide a way to identify quickly what has gone wrong in the event of any problems.

Lumigo co-founder and Chief Executive Erez Berkner (pictured right, next to co-founder and CTO Aviad Mor) recently appeared on theCUBE, SiliconANGLE Media’s livestreaming studio, where he provided a detailed rundown of how the Lumigo platform works.

“Lumigo as a SaaS platform allows you to know what’s happening, get visibility, and be able to get to the root cause of issues before they hit your production,” he explained.

Lumigo is easy to deploy with “no code” integration in just a couple of clicks, thanks to a strong automation engine that’s based on AWS Lambda layer integration, Berkner said.

The CEO claimed two major benefits of using Lumigo. The first is the visibility across a company’s entire range of serverless deployments.

“Because we’re connected to the environment, we alert on things that are relevant to serverless,” Berkner said. “It’s about concurrency limits, it’s about cold start, it’s about time outs, it’s about reaching duration limits. … It’s not a generic metric; it’s a serverless metric.”

The second key advantage is Lumigo goes further than just telling developers what the problem is. It also provides suggestions on how to fix things. By clicking on any issue it flags, developers can view a complete timeline of what happened and why it broke.

“It tells you the entire story end to end of that specific request, with inputs, with outputs, with environment variables,” Berkner explained. “All the things the developer needs in order to debug, to find the root cause, and then fix it in a matter of minutes.”

Lumigo has seen its user base grow sharply since exiting stealth in 2019. It says its debugging tools are used by hundreds of companies, including Medtronic Plc., Fortinet Inc. Berlitz Corp. and Allianz SE.

With today’s funding announcement, Lumigo said, it’s expanding its SaaS tools to software containers, which host the components of modern cloud-native applications, as well as Kubernetes and virtual machines.

“When you combine two mega tech trends, in this case serverless and observability, good things happen for both enterprises and vendors,” said analyst Holger Mueller of Constellation Research Inc. “This is the case with Lumigo, which is combining both trends to help enterprises and vendors. It’s good to see it’s getting funding to invest further in its monitoring tools for next-generation applications.”

Lumigo said it plans to use the money it has raised to double its core team, which currently numbers 30 employees. The main focus will be on expanding its marketing and product teams, and on recruiting more developers, it said.

“The new investment will ensure Lumigo remains the most versatile, powerful and accessible cloud-native observability platform, helping tens of thousands of developers understand how their applications behave in the real world,” Berkner said in a statement.
