Graylog Completes $18 Million Growth Equity Round

Graylog announced an $18 million growth equity round led by new investor Harbert Growth Partners and co-investor Piper Sandler Merchant Banking.

The round also included participation from existing investors Mercury Fund, High-Tech Gruenderfonds (HTGF), and Integr8d Capital. The investment will fuel the company’s growth plans.

“Graylog is well-positioned to be a long-term winner in the rapidly growing market for log management and analysis solutions,” said Brian Carney, General Partner, Harbert Growth Partners. “With its focus on delivering a superior analyst experience coupled with a vibrant Open Source community, the company provides customers a compelling alternative to other log management solutions plagued with high complexity and high total cost of ownership (TCO).”

“Our diligence showed a customer base that loves the blend of Graylog’s search and analysis experience, performance, scalability and overall flexibility. The company has a great foundation to build from...” said Bob Rinek, Managing Director, Piper Sandler Merchant Banking.

Graylog continued to grow rapidly during the challenging business climate over the last year. The company recently expanded its European operations and won several awards, including Editor’s Choice for SIEM from Cyber Defense Magazine and the 2021 Gold Stevie Award for DevOps Solutions.

“This investment will enable us to accelerate our global go-to-market strategies and enhancements to the award-winning solutions we deliver for IT, DevOps, and Security teams,” said Andy Grolnick, CEO of Graylog.

Outages aren't new. What's new is how quickly they spread across systems, vendors, regions and customer workflows. The moment that performance degrades, expectations escalate fast. In today's always-on environment, an outage isn't just a technical event. It's a trust event ...

Most organizations approach OpenTelemetry as a collection of individual tools they need to assemble from scratch. This view misses the bigger picture. OpenTelemetry is a complete telemetry framework with composable components that address specific problems at different stages of organizational maturity. You start with what you need today and adopt additional pieces as your observability practices evolve ...

One of the earliest lessons I learned from architecting throughput-heavy services is that simplicity wins repeatedly: fewer moving parts, loosely coupled execution (fewer synchronous calls), and precise timing metering. You want data and decisions to travel the shortest possible path. The goal is to build a system where every strategy and each line of code (contention is the key metric) complements the decision trees ...

As discussions around AI "autonomous coworkers" accelerate, many industry projections assume that agents will soon operate alongside human staff in making decisions, taking actions, and managing tasks with minimal oversight. But a growing number of critics (including some of the developers building these systems) argue that the industry still has a long way to go to be able to treat AI agents like fully trusted teammates ...

Enterprise AI has entered a transformational phase where, according to Digitate's recently released survey, Agentic AI and the Future of Enterprise IT, companies are moving beyond traditional automation toward Agentic AI systems designed to reason, adapt, and collaborate alongside human teams ...

The numbers back this urgency up. A recent Zapier survey shows that 92% of enterprises now treat AI as a top priority. Leaders want it, and teams are clamoring for it. But if you look closer at the operations of these companies, you see a different picture. The rollout is slow. The results are often delayed. There's a disconnect between what leaders want and what their technical infrastructure can handle ...

Kyndryl's 2025 Readiness Report revealed that 61% of global business and technology leaders report increasing pressure from boards and regulators to prove AI's ROI. As the technology evolves and expectations continue to rise, leaders are compelled to generate and prove impact before scaling further. This will lead to a decisive turning point in 2026 ...

Cloudflare's disruption illustrates how quickly a single provider's issue cascades into widespread exposure. Many organizations don't fully realize how tightly their systems are coupled to thirdparty services, or how quickly availability and security concerns align when those services falter ... You can't avoid these dependencies, but you can understand them ...

If you work with AI, you know this story. A model performs during testing, looks great in early reviews, works perfectly in production and then slowly loses relevance after operating for a while. Everything on the surface looks perfect — pipelines are running, predictions or recommendations are error-free, data quality checks show green; yet outcomes don't meet the ground reality. This pattern often repeats across enterprise AI programs. Take for example, a mid-sized retail banking and wealth-management firm with heavy investments in AI-powered risk analytics, fraud detection and personalized credit-decisioning systems. The model worked well for a while, but transactions increased, so did false positives by 18% ...

Basic uptime is no longer the gold standard. By 2026, network monitoring must do more than report status, it must explain performance in a hybrid-first world. Networks are no longer just static support systems; they are agile, distributed architectures that sit at the very heart of the customer experience and the business outcomes ... The following five trends represent the new standard for network health, providing a blueprint for teams to move from reactive troubleshooting to a proactive, integrated future ...
