Harness, a San Francisco-based software delivery platform that uses AI agents to automate testing, verification, security and governance, has raised a \$240 million Series E that values the company at \$5.5 billion post-money. The round consists of a \$200 million primary investment led by Goldman Sachs and a planned \$40 million tender offer with participation from IVP, Menlo Ventures and Unusual Ventures, designed to give some liquidity to long-serving employees. The valuation is a 49% jump from the \$3.7 billion the company reached in April 2022, and brings total equity raised to \$570 million.
The thesis is about where AI has moved the bottleneck rather than where it removed one. As models accelerate code production, the burden shifts to what CEO Jyoti Bansal calls the "after-code" phase — testing, security checks and deployment — which he says still consumes nearly 70% of engineering time. More generated code means more to review, verify and ship safely, and the cost of a single faulty line reaching production has not fallen at all.
Harness's approach rests on a software delivery knowledge graph that maps code changes, services, deployments, tests, environments, incidents, policies and costs. Purpose-built agents use that graph as context to generate pipelines matching a customer's own architecture, policies and operational requirements, and an orchestration engine turns recommendations into automated actions with checks in place before anything is applied. Bansal stresses that AI-generated tests and fixes are reviewed by engineers, compliance teams or auditors before use — human oversight by design, not by exception.
The company cites more than 1,000 enterprise customers, including United Airlines, Morningstar, Keller Williams and National Australia Bank. On its own figures it has handled 128 million deployments, 81 million builds and protected 1.2 trillion API calls, while helping customers optimize \$1.9 billion in cloud spending over the past year. Those operational and revenue figures come from the company and have not been independently audited.
Competition is dense: Microsoft's GitHub, GitLab, Jenkins and CloudBees all sit in adjacent territory, and the incumbents can bundle. Harness argues the knowledge graph is what differentiates it, because a general model cannot know a specific company's delivery topology. That is a defensible moat only as long as the graph is expensive to replicate — a claim the market has so far accepted rather than tested.
Bansal is a known quantity to enterprise software investors. He built AppDynamics and sold it to Cisco for \$3.7 billion in 2017. Harness, founded in 2017, employs more than 1,200 people across 14 offices, with roughly a third of staff in India and its Bengaluru site serving as the largest development centre outside the United States. Earlier this year the company absorbed Traceable, Bansal's API security firm, folding application security into the same platform.
The new capital goes into research and development — hiring what Bansal describes as hundreds of engineers in Bengaluru — and into expanding automated testing, deployment and security capabilities while improving the accuracy of the agents. He says an eventual IPO remains the plan, without giving a timeline.
The read-through is that capital is starting to rotate away from the model layer toward the plumbing that makes AI-generated output shippable. That is a healthier place to be standing than a pure model play if the industry's next problem is reliability rather than capability. The risk is structural: if code review, testing and deployment automation become default features of GitHub and GitLab rather than paid products in their own right, a \$5.5 billion valuation will need the knowledge graph to hold up as a real moat — and that argument gets settled inside customers' delivery pipelines, not in a funding announcement.
