Undo Closes $37 Million Growth Investment to Debug Mission-Critical Software for AI Era.
Cambridge, UK – June 15, 2026
Undo, an authority on artificial intelligence (AI)-powered root-cause analysis, today announced the close of a $37 million funding round led by Elsewhere Partners. Successfully helping software engineering teams at top networking, database, semiconductor, and financial services companies solve complex code problems across development, testing and production, Undo will use the investment to accelerate development efforts and significantly expand its global market reach.
“AI is making code unmanageable – introducing code that engineers cannot understand, trust, or debug. So while AI helps them generate more code, some of it is poorly understood, poorly structured, and of questionable quality. Systems become full of unknowns, making them unstable and increasing the risk of outages, security breaches, and customer escalations,” noted Elsewhere Operating Partner Rod Favaron. “Undo ensures engineering teams can effectively operate complex systems in an AI-first world and provide the essential runtime context for enterprise-grade, AI-assisted software.”
Undo fills a critical gap by giving AI agents the runtime context needed to reliably diagnose complex software issues in multifaceted systems. By capturing complete execution history (how code actually behaves when running) into self-contained recordings, Undo enables AI agents to perform accurate root-cause analysis and ensures even AI-generated code remains understandable and maintainable. No matter how good AI models get, results are limited by how good the context is: AI = model + context. Runtime context tells the model what the program did, rather than just what the code says, so the models perform significantly better. The company’s benchmarks on a range of complex bugs show even the very latest models are able to identify the root-cause of just 38% without Undo; whereas with Undo’s runtime context that increases to 92%. In addition, in cases where models can solve a problem without Undo, when the same problem is solved with Undo far fewer tokens are used. Customers report completion of root-cause analysis 100x faster with Undo than before.
“Quality is extremely important at Palo Alto Networks, and we cannot afford to rely on guesswork. The hardest—and costliest—bugs in multi-million-line codebases live in runtime state and are not captured by logs or other solutions,” said Suresh Sangiah, Senior VP Engineering at Palo Alto Networks. “Undo provides the visibility needed to catch and correct errors before they become an operational problem for our customers, enabling automatic root-cause analysis. Undo often autonomously finds the root causes in minutes.”
Already delivering up to 100× faster resolution and more predictable outcomes for top enterprise software teams across the world, Undo is primed for rapid growth. The company plans to significantly scale its product development, customer support, and go-to-market teams across the United States and Europe to support the expansion and adoption of its solutions as software engineering needs evolve.
“We are ahead of the curve. Undo has spent years building deterministic, program recording technology for code failure runtime visibility, which has become absolutely essential with the rise of AI,” added Undo Founder and CEO Greg Law. “This investment allows us to accelerate at exactly the right moment – embedding Undo into AI workflows, scaling our commercial reach, and ensuring we are an essential part of how engineering teams operate in this new, AI-first world. We look forward to working alongside the Elsewhere team to ease the next era of software engineering problems for companies around the world.”
Favaron will lead the Board of Directors as Executive Chair, with support from Elsewhere Operating Executive Thom Everett and Elsewhere Operating Advisor Damion Heredia. Undo will leverage the deep expertise and extensive network of the Elsewhere Operating Partners and Advisors to effectively deliver high-impact solutions, expand market reach and build out its leadership teams.
