Israeli startup Lightrun has raised $70 million in a Series B funding round announced on April 28, 2025. The investment was co-led by Accel and Insight Partners. This funding brings Lightrun’s total capital raised to $110 million. The company specializes in AI-driven tools that help developers debug code in real time.
About Lightrun’s AI Debugging Platform
Lightrun’s solutions offer real-time observability and debugging inside developers’ integrated development environments (IDEs). Its platform helps identify and fix code issues before they escalate. In July 2024, the startup launched the Runtime Autonomous AI Debugger to proactively remediate software bugs using AI.
The CEO, Ilan Peleg, highlighted the importance of proactive debugging, stating, “Code is becoming cheap but bugs are expensive.” His team aims to reduce downtime and improve reliability by spotting problems early in complex AI-generated codebases.
Significance of the Funding
The funding reflects growing demand amid increasing software complexity and AI-generated coding. Investors noted Lightrun’s 4.5-fold revenue growth since launching its AI debugging tool, showing strong market traction.
Accel partner Andrei Brasoveanu said the company’s success accelerated due to AI’s role in code expansion. Many enterprises face rising challenges that Lightrun’s platform directly addresses.
Notable Clients and Future Plans
Lightrun counts major clients like Citi, Microsoft, and Salesforce, with Citi also participating as an investor. These relationships underscore Lightrun’s relevance in enterprise software markets.
The startup plans to enhance its platform further, focusing on observability and debugging within the IDE. Potential future growth areas include cybersecurity tools and deeper integration into code creation.
