SigScalr Emerges from Stealth

SigScalr, a unified observability SaaS solution that is purpose-built to process large volumes of observability data, has emerged from stealth and closed a $1.76M pre-seed round.

Scribble Ventures led the round with co-investments from WestWave Capital and Forward Slash Capital.

The fresh capital will enable SigScalr to launch its open-source software (OSS) product SigLens, a column oriented database built from scratch for observability. The company will also expand its go-to-market efforts and recruit experts in the software and product development space to power innovation surrounding the observability market.

SigScalr’s OSS product SigLens was purpose-built. It is a columnar database with dynamic compression that adjusts as data streams in, making it an extremely compact and efficient service. Using micro-indices, SigLens narrows search space, enabling rapid speed queries. Functionally, the platform allows performance engineers to search over compressed data without uncompressing 98% of data.

Additional features and benefits of SigLens include:

- Scalability: Regardless of your dataset's size, SigLen’s horizontal scalability has you covered.

- Efficiency: Leverage the full potential of your hardware and cloud resources with SigLens's efficiency.

- Fast: SigLens can search and aggregate billions of log lines in under a second.

- Ease of use: SigLens offers an intuitive interface, making it accessible even for those unfamiliar with observability tools.

- Compatibility: SigLens offers query compatibility with every observability tool. It is a drop-in replacement for your existing observability tool.

“Most observability platforms specialize on key areas to support log management, metrics and traces forcing developers to tirelessly switch between platforms in order to troubleshoot productivity issues,” said Kunal Nawale, SigScalr founder and CEO. “For a fresh engineer entering the field, the number of tools available for observability is inscrutable and overwhelming. SigScalr is the only unified observability platform enabling developers to seamlessly consolidate observability tools and effectively reduce cloud infrastructure spend and debug issues faster.”

The platform is also highly scalable, permitting developers to run thousands of concurrent queries under a second on terabytes of data and allowing up to 1 petabytes of data overall. SigScalr addresses financial concerns by operating inside organizational firewalls if they choose or can be hosted with their SaaS connection.

“Kunal and the team are elevating the developer experience by creating a solution to maximize their productivity,” said Elizabeth Weil, founder of Scribble Ventures. “The vast majority of existing software companies spend too much time on provisioning tools to help identify application issues resulting in unnecessary wasted time and cost. SigScalr has been tested to outperform similar solutions and we are excited to be a part of this innovation for the software market.”

“SigScalr is a pioneer for the observability space, and we’re proud to be a part of this funding round at its critical stage of growth,” said Gaurav Manglik, partner at WestWave. “They have a deep, peer-to-peer understanding of the issues developers face surrounding complex systems. The company’s unified approach is tailored to support the future of observability solutions.”
