Rookout, a startup that provides debugging across a variety of environments, including serverless and containers, announced an $8 million Series A investment today. It plans to use the money to expand beyond its debugging roots.

The round was led by Cisco Investments along with existing investors TLV Partners and Emerge. Nat Friedman, CEO of GitHub; John Kodumal, CTO and co-founder of LaunchDarkly; and Raymond Colletti, VP of revenue at Codecov also participated.

“Rookout from day one has been working to provide production debugging and collection capabilities to all platforms,” Or Weis, co-founder and CEO of Rookout told TechCrunch. That has included serverless like AWS Lambda, containers and Kubernetes and Platform-as-a-Service like Google App Engine and Elastic Beanstalk.

The company is also giving visibility into platforms that are sometimes hard to observe because of the ephemeral nature of the technology, and that go beyond its pure debugging capabilities. “In the last year, we’ve discovered that our customers are finding completely new ways to use Rookout’s code-level data collection capabilities and that we need to accommodate, support and enhance the many varied uses of code-level observability and pipelining,” Weiss said in a statement.

It was particularly telling that a company like Cisco was deeply involved in the round. Rob Salvagno, vice president of Cisco Global Corporate Development and Cisco Investments, likes the developer focus of the company.

“Developers have become key influencers of enterprise IT spend. By collecting data on-demand without re-deploying, Rookout created a Developer-centric software, which short-circuits complexities in the production debugging, increases Developer efficiency and reduces the friction which exists between IT Ops and Developers,” Salvagno said in a statement.

Rookout, which launched in 2017, has offices in San Francisco and Tel Aviv, with a total of 20 employees. It has raised more than $12 million.
