Zenoss Raises $25 Million in Funding

Zenoss announced the closing of $25 million in Series C funding led by growth equity investor Summit Partners.

Existing investors Grotech Ventures, Intersouth Partners and Boulder Ventures also participated in the round, which will be used to further accelerate the company’s product innovation and global expansion to support continued rapid growth.

With the $25 million investment, Zenoss has raised a total of $45 million to date.

Founded in 2005, Zenoss offers a next generation IT operations platform that includes unified monitoring, scale event management, real-time service impact/root cause analysis, and automated remediation. Built on an open software architecture around a real-time service model, Zenoss allows IT organizations to consolidate their operational tools and further automate their core processes. The result is improved service quality, significant cost savings and more rapid response to change.

Zenoss has also continued to expand its open source community with a total of 2.4 million downloads of its open source product.

“This raise will help fuel continued innovation, community expansion and growth of our commercial business,” said Bill Karpovich, co-founder and CEO of Zenoss. “We are delighted to have Summit Partners join the team as their experience and success with rapidly-growing companies makes them the ideal partner for Zenoss at this stage of the company’s growth.”

Tom Jennings, a Managing Director of Summit Partners who will join the Zenoss Board of Directors, said “Zenoss is unique because it has been purposely built for managing virtual and cloud based infrastructures on top of legacy environments. The company’s value proposition to customers, rapid growth and recurring revenue reminds us of many great software companies we have backed over the years.”

Michael Medici, a Principal of Summit Partners who will be a Board Observer, added “We look forward to working closely with Bill Karpovich and the rest of the Zenoss management team to continue growing this exceptional company.”

Like most digital transformation shifts, organizations often prioritize productivity and leave security and observability to keep pace. This usually translates to both the mass implementation of new technology and fragmented monitoring and observability (M&O) tooling. In the era of AI and varied cloud architecture, a disparate observability function can be dangerous. IT teams will lack a complete picture of their IT environment, making it harder to diagnose issues while slowing down mean time to resolve (MTTR). In fact, according to recent data from the SolarWinds State of Monitoring & Observability Report, 77% of IT personnel said the lack of visibility across their on-prem and cloud architecture was an issue ...

Technology management is evolving, and in turn, so is the scope of FinOps. The FinOps Foundation recently updated their mission statement from "advancing the people who manage the value of cloud" to "advancing the people who manage the value of technology." This seemingly small change solidifies a larger evolution: FinOps practitioners have organically expanded to be focused on more than just cloud cost optimization. Today, FinOps teams are largely — and quickly — expanding their job descriptions, evolving into a critical function for managing the full value of technology ...

Enterprises are under pressure to scale AI quickly. Yet despite considerable investment, adoption continues to stall. One of the most overlooked reasons is vendor sprawl ... In reality, no organization deliberately sets out to create sprawling vendor ecosystems.

Nearly every conversation about AI eventually circles back to compute. GPUs dominate the headlines while cloud platforms compete for workloads and model benchmarks drive investment decisions. But underneath that noise, a quieter infrastructure challenge is taking shape.

In the modern enterprise, the conversation around AI has moved past skepticism toward a stage of active adoption. According to our 2026 State of IT Trends Report: The Human Side of Autonomous AI, nearly 90% of IT professionals view AI as a net positive, and this optimism is well-founded.
