Lightrun's New $70M Fund: AI-Powered Code That Detects and Fixes Itself

Lightrun Co-Founders: Leonid Blouvshtein (CTO) and Ilan Peleg (CEO)

As enterprises race to keep up with the breakneck pace of software delivery in the GenAI era, one Israeli startup is betting that fixing software, not just observing it, will define the future of the industry.

Lightrun, a developer observability platform based in Tel Aviv, announced on Monday that it has raised $70 million in Series B funding, led by Accel and Insight Partners, with participation from Citi, Glilot Capital, GTM Capital, and Sorenson Capital. The round brings Lightrun’s total funding to $110 million and marks a critical moment as the company moves from traditional observability into the emerging domain of autonomous remediation.

The company’s bet is straightforward but radical: instead of merely monitoring for production issues, Lightrun’s platform uses AI to detect, diagnose, and even suggest code fixes in real time—turning runtime incidents from days-long emergencies into minute-long events.

“In 2024, dramatic shifts in the software development lifecycle — from AI-driven code generation to increased demands for operational resilience — have made production systems more vulnerable,” said Ilan Peleg, CEO of Lightrun. “Our goal is to ensure that once code reaches production, teams can move fast and stay reliable. As autonomous software development becomes reality, we see the next frontier in autonomous remediation — software that can fix itself.”

Lightrun currently employs around 80 people, including 60 in Israel, and the rest in New York.

The need for solutions like Lightrun’s is growing fast. While AI code assistants like GitHub Copilot have accelerated coding and testing, resilience at the production stage has lagged. Lightrun addresses this widening gap by embedding live debugging and real-time remediation directly into developers' existing workflows, offering a proactive shield before issues impact users.

According to the company, its revenue has grown 4.5× year over year, the team has doubled in size, and the customer roster now includes heavyweights such as Citi, Salesforce, Microsoft, SAP, AT&T, Priceline, and the NYSE.
