Fiberplane is a technology company.
Fiberplane develops a collaborative notebook platform for site reliability engineers and DevOps teams. This tool unifies real-time investigation and documentation, centralizing infrastructure incident diagnosis, mitigation, and system analysis. Consolidating diverse data and operational tools within an interactive workspace, the platform empowers technical teams to efficiently resolve production issues, reducing downtime and enhancing clarity during critical events.
Micha Hernandez van Leuffen founded Fiberplane in 2020. His experience, including establishing Wercker, revealed incident response inefficiencies across complex distributed systems. Van Leuffen recognized the need for a unified platform enabling engineering teams to collaborate with integrated data during operational crises, directly addressing fragmented tools and communication challenges.
Fiberplane serves SREs, developers, and operations teams managing sophisticated technical infrastructures. The company aims for faster, more precise incident resolution, transforming reactive troubleshooting into a structured, collaborative, knowledge-driven process. Its mission is to optimize incident management, facilitate continuous learning, and ultimately boost critical system reliability and performance.
Fiberplane has raised $9.0M across 1 funding round.

# Fiberplane: High-Level Overview
Fiberplane is a developer-focused observability and incident response platform that enables site reliability engineers (SREs) and DevOps teams to collaborate in real-time during system outages.[2] The company builds collaborative notebooks and open-source tools that integrate with existing observability stacks, allowing teams to pull in various data types, work together to resolve incidents, and maintain a natural audit trail of the resolution process.[2][5]
The platform addresses a critical pain point in modern infrastructure management: the fragmented, time-consuming nature of incident response. Rather than jumping between multiple tools and communication channels, Fiberplane provides a unified workspace where multiple engineers can simultaneously investigate and resolve production issues—similar to how Google Docs enables collaborative document editing.[2] The company serves engineering teams at organizations running distributed systems, where outages require coordinated expertise across multiple specialists.
# Origin Story
Fiberplane was founded in October 2020 by Micha "mies" Hernandez van Leuffen, who previously founded and served as CEO of Wercker, a CI/CD platform acquired by Oracle in 2017.[3] The founding insight emerged directly from Hernandez van Leuffen's experience at Oracle: he recognized that DevOps teams and SREs lacked the collaborative tools that other departments took for granted.[2] While product teams used Google Docs for real-time collaboration, incident response remained siloed and inefficient.
The company achieved early validation quickly, raising a €7.5 million seed round in September 2021—approximately $8.8 million USD—co-led by Crane Venture Partners and Notion Capital, with participation from Northzone, System.One, and Basecase Capital.[2] By 2023, Fiberplane had expanded its product vision beyond incident response notebooks, launching Autometrics Explorer, an open-source observability tool designed to give every engineer insight into code performance at the code level.[3] The company has grown from 13 employees at the time of its seed announcement to 20-50 employees as of 2023.[2][3]
# Core Differentiators
# Role in the Broader Tech Landscape
Fiberplane operates at the intersection of two major trends reshaping software engineering: the shift toward distributed systems and microservices and the democratization of developer tools. As systems become more complex and outages more costly, the need for faster incident response has become a competitive advantage. Traditional observability platforms—built for specialists and requiring extensive training—create bottlenecks precisely when speed matters most.
Fiberplane's emphasis on accessibility and collaboration reflects a broader industry movement toward developer experience (DX) as a core product differentiator. Companies like Notion, Figma, and Vercel have demonstrated that tools designed with user experience at their center can capture significant market share, even in crowded categories. By bringing collaborative editing and code-level observability to incident response, Fiberplane is helping to professionalize and democratize a critical but historically fragmented practice.
The company's backing by Crane Venture Partners—a firm focused on infrastructure and developer tools—signals confidence in this thesis. Additionally, Fiberplane's open-source strategy (Autometrics is open-source) positions it to build community momentum and become a de facto standard, similar to how other open-source projects have shaped infrastructure tooling.[3]
# Quick Take & Future Outlook
Fiberplane is well-positioned to capture share in the observability market by solving a problem that existing vendors have largely ignored: making incident response collaborative and accessible. The company's evolution from incident response notebooks to a broader observability platform (Autometrics Explorer) suggests ambitions to become a comprehensive SRE workbench—a vision articulated by founder Hernandez van Leuffen in 2021.[2]
The timing is favorable. As organizations increasingly adopt cloud-native architectures and face pressure to reduce mean time to resolution (MTTR), tools that accelerate incident response and reduce cognitive load will become essential. Fiberplane's open-source strategy and focus on developer experience position it to build network effects and community adoption—potential moats that proprietary observability vendors struggle to match.
Looking ahead, the company's success will likely depend on its ability to expand beyond incident response into the broader SRE workbench vision while maintaining the simplicity and accessibility that differentiate it. If Fiberplane can establish itself as the collaborative nerve center for infrastructure teams, it could influence how the entire industry approaches observability and incident management.
Fiberplane has raised $9.0M across 1 funding round. Most recently, it raised $9.0M Seed in September 2021.
