Traversal Lands $120M to Automate Software Outage Resolution

The big picture: Traversal, an AI startup building autonomous engineers to diagnose and resolve software outages, has raised $120 million in fresh funding at a $1 billion valuation. This Series B round was co-led by Kleiner Perkins, Redpoint Ventures, and Khosla Ventures, joining the growing ranks of AI unicorns.

Why it matters:

• Rising Downtime Costs: As AI coding tools accelerate software development, managing production environments becomes more complex, with downtime costs increasing 50% over two years to an estimated $600 billion annually.
• Engineer Burden: Engineers spend roughly seven hours each week troubleshooting problems, creating a significant burden that Traversal aims to alleviate by automating the less glamorous side of software development.
• Enterprise Adoption: Major enterprises like Nubank, Harvey, DigitalOcean, and PepsiCo are already adopting Traversal’s AI site reliability engineers (SREs) to investigate outages, identify root causes, and fix problems before they escalate.

How it works:

• Autonomous Agents: Traversal’s platform deploys AI SREs, autonomous agents designed to investigate software outages, pinpoint their root causes, and assist engineering teams in resolving issues.
• Causal Machine Learning: The company’s approach leverages causal machine learning to distinguish between symptoms and underlying causes of failures, using a continuously updated model of production systems to recommend or execute fixes.
• Proven Impact: Traversal reports a ninefold increase in annual recurring revenue since early 2026, with product usage growing nearly 100 times and monthly active users increasing almost 20 times, supporting over 4,000 engineers across 150,000 investigations last quarter.

The catch: While AI is transforming code generation, building truly autonomous AI engineers capable of independently managing complex production systems remains an unsolved challenge. Benchmarks show current AI agents still exhibit limited accuracy and high hallucination rates when dealing with medium-difficulty or underspecified incidents, highlighting a significant gap in reasoning capabilities for live enterprise infrastructure.
