Israeli technology company Lightrun has secured new Series B funding in a round co-led by Accel and Insight Partners, announced on April 28, 2025. Although the precise amount raised was not disclosed, the investment highlights the rapid momentum behind Lightrun´s Artificial Intelligence-powered platform aimed at streamlining code debugging for software developers. Lightrun, founded to tackle the increasing challenges of maintaining reliable code in the age of Artificial Intelligence-generated software, delivers observability and debugging tools directly within popular integrated development environments (IDEs).
The company´s CEO, Ilan Peleg, noted that as software development accelerates with Artificial Intelligence-assisted code generation, bugs have become increasingly expensive and difficult to manage. Lightrun’s solution addresses this pain point by providing real-time, proactive code monitoring and error detection, allowing engineers to identify and remediate issues before they escalate. A key milestone for Lightrun was the July 2024 launch of the Runtime Autonomous AI Debugger, designed to autonomously fix bugs and minimize downtime, supporting both complex legacy codebases and modern automated code.
The Series B funding reflects heightened investor confidence, attributed to Lightrun´s 4.5-fold revenue growth since the introduction of its Artificial Intelligence debugging tools. Accel partner Andrei Brasoveanu underscored the critical role Lightrun plays as enterprises confront growing software complexity, especially with Artificial Intelligence playing a bigger part in development workflows. Lightrun´s roster of enterprise clients includes Citi, Microsoft, and Salesforce, with Citi also participating as an investor—further evidence of its traction in the enterprise market. Looking forward, Lightrun plans to expand its core offering with enhanced observability, further automation, and potential integrations in cybersecurity and broader code creation processes, reinforcing its ambition to be a leading solution for modern software reliability.
