Traversal, a New York-based artificial intelligence startup focused on software reliability, has raised $120 millon in Series B funding at a $1 billion valuation.
The company announced the funding on November 3, 2026. Kleiner Perkins, Redpoint Ventures and Khosla Ventures co-led the round, with additional participation from Sequoia Capital and Battery Ventures.
The investment gives Traversal the financial backing to expand its AI platform, which helps businesses identify the causes of software failures, investigate production incidents and support the process of fixing them.
Traversal operates in a technical field known as site reliability engineering (SRE). The company calls its approach AI SRE because its platform uses artificial intelligence agents to handle parts of the work traditionally performed by human reliability engineers.
The startup plans to use the new funding to hire across engineering, research and go-to-market teams. Its wider ambition is to build what it describes as self-driving production, where AI systems handle more of the work involved in keeping business software reliable.
Founded in 2023, Traversal reached a $1 billion valuation roughly three years after its creation. The new funding round also represents a major increase from the $48 million in combined seed and Series A funding it announced when emerging from stealth in June 2025.
Traversal Raises $120 Million in Series B Funding
Traversal’s latest funding round values the company at $1 billion.
Kleiner Perkins, Redpoint Ventures and Khosla Ventures co-led the $120 million investment. Sequoia Capital and Battery Ventures also participated, while Kleiner Perkins and Sequoia increased their existing investments.
The funding announcement marks a major step in Traversal’s growth as demand increases for AI tools designed to manage complex software environments.
The company’s platform targets a problem faced by businesses that depend on digital services. When an application, payment system or online platform stops working, engineers need to identify the source of the failure before restoring normal operations.
These investigations often involve large volumes of technical information, including system logs, performance measurements, software changes and service dependencies.
Traversal wants its AI agents to handle much of this investigation work, helping engineering teams identify problems faster and reduce the time spent responding to incidents.
According to the company’s announcement, the new capital will support further development of its AI SRE platform and expansion across research, engineering and commercial teams.
Goodwin, the law firm that advised Traversal on the transaction, also confirmed the $120 million funding round and $1 billion valuation.
What Does Traversal Do?
Traversal builds AI agents designed to help companies investigate and resolve software reliability problems.
To understand its business, readers need to understand site reliability engineering.
Site reliability engineering is the practice of keeping software applications, websites and digital infrastructure available and working as expected.
Companies rely on SRE teams to monitor their systems, investigate failures, respond to alerts and prevent recurring problems.
For example, an online payment platform might suddenly stop processing transactions. The visible problem is easy to identify, but the cause might sit several layers deeper.
A database might respond too slowly. A recent software update might have introduced an error. Another service connected to the payment system might be experiencing a failure.
Engineers need to examine these connected systems before identifying the source of the incident.
Traditional investigations often require engineers to move between monitoring dashboards, logs, code repositories and deployment records.
Traversal wants its AI agents to perform much of this work automatically.
Its platform examines information from a company’s production environment, investigates possible causes and provides findings to help engineers decide how to respond.
The company describes this approach as AI SRE.
Rather than replacing every responsibility of a human reliability engineer, the platform aims to automate time-consuming investigation tasks and support faster incident response.
How Traversal’s AI SRE Platform Works
Traversal’s technology centres on two main systems: its Production World Model and Causal Search Engine.
The company introduced these technologies in March 2026 after nearly two years of research and engineering.
Both systems address a major challenge in software troubleshooting: identifying the actual cause of a failure rather than focusing on symptoms that happen around the same time.
1. Production World Model
The Production World Model provides an AI-readable representation of a company’s live software environment.
It brings together information from different parts of a production system, including:
- Application services.
- Infrastructure and APIs.
- System logs and performance data.
- Software code.
- Deployment histories.
- Service dependencies.
- Previous incidents and operational knowledge.
This information helps the AI understand how different parts of a company’s software connect and depend on one another.
For example, if an online store experiences checkout problems, the system needs to examine more than the checkout application itself.
The issue might come from a payment service, database or another connected component.
Traversal’s Production World Model aims to give its AI agents a wider view of these relationships.
According to the company, the model updates as production environments change. This allows the system to account for new deployments, changing dependencies and other operational updates.
The goal is to give AI agents a more complete picture of how software behaves during normal operations and technical incidents.
2. Causal Search Engine
The second component is Traversal’s Causal Search Engine.
This system investigates possible reasons behind software failures.
A major challenge in troubleshooting is separating correlation from causation.
Two software services might experience problems at the same time, but one issue does not automatically cause the other.
An AI system that relies only on matching patterns might identify the wrong source of a failure.
Traversal says its Causal Search Engine addresses this problem by testing multiple possible explanations and examining the relationships between connected services.
The company says the engine investigates thousands of hypotheses in parallel. It uses information from the Production World Model to examine possible causes and narrow down the source of an incident.
The objective is to produce evidence-backed findings rather than a response based only on patterns in the available data.
Traversal says this approach helps its agents investigate complex failures involving several connected services.
The company’s technical descriptions explain how the two systems work together. The Production World Model provides the system context, while the Causal Search Engine uses that context to investigate possible causes.
Anish Agarwal’s Causal Machine Learning Background
Traversal’s approach draws on the founders’ academic research in artificial intelligence, causal machine learning and reinforcement learning.
CEO and co-founder Anish Agarwal has a background in causal machine learning. He earned a PhD in Computer Science from the Massachusetts Institute of Technology and has worked as a researcher in the field.
His academic profile at Columbia University lists causal machine learning and its applications to engineering and social systems among his research interests.
Other members of the founding team also bring research experience.
Co-founder Raaz Dwivedi has a background in causal machine learning and reinforcement learning. He earned his PhD at the University of California, Berkeley and is associated with Cornell Tech.
Raj Agrawal earned his PhD at MIT, while Ahmed Lone brings experience from quantitative trading at Citadel Securities.
Traversal says this research background influenced the development of its AI SRE technology.
The company’s approach focuses on teaching AI systems to reason about cause-and-effect relationships across complex software environments.
This distinction matters because identifying the correct cause of an outage often requires more than recognising unusual activity.
The system needs to understand how services connect, what changed before the failure and which events explain the problem.
Traversal presents causal reasoning as a central part of its effort to improve automated software troubleshooting. Its claims about accuracy and performance should still be understood as company-reported results rather than guarantees for every production environment.
Traversal Reached a $1 Billion Valuation in About Three Years
Traversal was founded in 2023 and announced its first major funding milestone when it emerged from stealth in June 2025.
At the time, the company announced $48 million in combined seed and Series A funding.
Sequoia Capital and Kleiner Perkins led the earlier investment, with participation from NFDG and Hanabi.
About 17 months later, Traversal announced its $120 million Series B at a $1 billion valuation.
The new round is 2.5 times the amount announced when the company emerged from stealth.
The timeline shows how quickly Traversal has attracted investor interest.
Its growth also reflects wider investment activity around AI infrastructure and enterprise software. Businesses are increasingly exploring AI tools for tasks beyond content generation and software development.
Companies need systems capable of monitoring, maintaining and troubleshooting the applications they already depend on.
Traversal is targeting this need through automated incident investigation and software reliability tools.
Its $1 billion valuation places the startup among privately valued technology companies with unicorn status.
Why Investors Are Interested in AI Site Reliability Engineering
AI has changed how many software teams build and release applications.
Coding assistants and AI development agents help engineers produce software faster. But more code and faster development also create additional work for teams responsible for keeping applications stable.
Every new feature, software update or service dependency introduces another possibility for technical problems.
When an incident occurs, engineers still need to identify the cause, understand its impact and decide how to restore normal operations.
This creates an opportunity for AI systems focused on software reliability.
Traversal’s platform targets this gap by helping businesses investigate incidents and understand their production environments.
The company also wants its technology to support tasks beyond traditional root cause analysis.
Its broader platform includes proactive AI agents called Traversal Workers. These agents start investigations when alerts or other anomalies appear, gather relevant information and help engineering teams move towards remediation.
Traversal also offers Traversal MCP, which connects production intelligence with AI coding agents.
The idea is to help development tools access information about how software behaves after deployment. This context could help engineers identify risks and make better decisions when changing applications.
These features support the company’s wider goal of connecting software development with production operations.
Traversal Cites Gartner Forecast on AI SRE Adoption
Traversal’s funding announcement also points to a growing market for AI-powered site reliability tools.
The company cites a Gartner projection stating that 85% of companies will use AI SRE tools by 2029, compared with fewer than 5% in 2025.
This forecast suggests a significant expected increase in enterprise adoption.
However, the projection comes from Traversal’s announcement. The figure should therefore be attributed to the company rather than presented as an independently verified market measurement.
The broader reason for interest in AI SRE is clear.
Businesses depend on software for payments, communication, customer services, logistics and internal operations. When these systems fail, downtime affects employees and customers.
Traditional reliability teams often need to investigate several connected services before finding the source of an incident.
AI agents designed for this work offer a way to automate parts of the process.
Traversal is competing in this developing market by focusing on causal reasoning and automated production investigations.
What Traversal Plans to Do With the $120 Million
Traversal says it will use the new funding to expand its research, engineering and go-to-market teams.
The investment will support further development of its AI SRE platform and help the company move towards its stated goal of self-driving production.
This vision involves AI systems taking on more responsibility for managing software environments.
Under the company’s long-term plan, AI agents would detect unusual activity, identify the causes of failures, recommend or carry out suitable corrections, verify whether those corrections worked and help prevent similar incidents.
The current funding announcement does not mean Traversal has already achieved fully autonomous software operations.
Instead, the company is investing in the technology and workforce needed to move towards this goal.
Its immediate focus remains improving its AI agents and expanding the range of production tasks they support.
What Happens Next?
Traversal’s next stage will focus on expanding its platform and increasing its presence among enterprise customers.
The company has already reported adoption among businesses such as Nubank, DigitalOcean, Harvey and PepsiCo. Its November funding announcement also points to wider enterprise use.
The additional capital gives Traversal more resources to develop its technology and expand its commercial operations.
Investors will likely watch how effectively the company turns its $1 billion valuation into long-term business growth.
Important measures will include customer adoption, revenue growth, product performance and the ability of its AI agents to handle increasingly complex production incidents.
The wider AI SRE market will also face questions about reliability, security and how much control businesses should give automated systems.
For now, Traversal is positioning itself as a company focused on reducing the human workload involved in keeping software running.
