Traversal raises $120 million Series B at $1 billion valuation

The $120 million Series B was announced at a $1 billion valuation on November 3, 2026.[1] Kleiner Perkins, Redpoint Ventures and Khosla Ventures co-led the financing, while Sequoia Capital, Battery Ventures and Amex Ventures also participated.[2] Traversal says Kleiner Perkins and Sequoia Capital increased their investments in the company.[3] The new round brings Traversal’s total funding to $173 million.[2] Traversal says the proceeds will help it hire across research, engineering and go-to-market roles.[3]

Traversal says its product is designed to help engineering teams autonomously diagnose, remediate and prevent production incidents.[2] Its Production World Model turns telemetry, code, deployment history and tribal knowledge into an AI-readable representation of production.[3] The company says its Causal Search Engine lets agents test thousands of hypotheses in parallel and converge on evidence-backed root causes.[3] Traversal Workers begin working when an anomaly, such as an incident or alert, occurs, gathering context and identifying root causes.[3] Traversal also says coding agents can use its live production understanding to build more resilient code and prevent incidents.[3]

Traversal reports that monthly investigations grew more than 100-fold in 2026, from 513 to nearly 73,000.[3] The company says roughly two-thirds of product usage now covers work beyond root-cause analysis, including alert triage, release risk and production support.[3] Traversal reports ninefold year-to-date growth in annual recurring revenue and nearly 20-fold growth in monthly active users.[2] It says customers ran more than 150,000 investigations in the most recent quarter and that the product supported over 4,000 engineers.[2] Customers it names include Nubank, Harvey, DigitalOcean and PepsiCo.[2]

Traversal says its ORCA-bench benchmark contains 1,079 root-cause-analysis tasks.[2] On the benchmark, the best-performing of five evaluated frontier agents achieved 25.3% accuracy on medium-difficulty incidents and 10% on vague-report incidents; hallucination rates reached as high as 40%.[2] Those scores do not measure Traversal’s own production performance.[1] The results therefore describe the evaluated agents on this benchmark, rather than establishing how Traversal performs in customers’ live environments.[2][1] Separately, a 2026 Splunk and Oxford Economics report found that downtime costs had risen 50% in two years.[2]
