Case Study: Luminance gains observability for engineering with Span

Luminance scales 120-engineer visibility with Span

Luminance, a legal AI company with a 120-person engineering team based in Cambridge, UK, faced a significant challenge: a lack of visibility into its engineering organization. The new CTO needed to transform the research lab into a modern SaaS company but had no tooling to understand where to focus attention or how effort was being spent. He manually dug through pull requests to build metrics, missing a broad view of engineering health and effectiveness. He sought an observability solution for his organization, similar to how technical stacks are monitored.

The company implemented Span, a developer intelligence platform described as observability for engineering orgs. The solution provided a bird's-eye view of the organization, allowing the CTO to spot anomalies and then drill down into specific teams, metrics, and even individual pull requests to understand the root cause. This data-driven approach bolstered cross-functional collaboration by providing an objective basis for conversations with engineering and product managers. The CTO chose Span over competitors because it delivered both high-level insights and the underlying data, enabling him to understand the impact of AI coding tools on quality and review processes and ultimately shape the company's AI strategy.
