**Harness sells software that automates testing and deploying the code developers write, and on Oct. 8 it bought Augment Code's coding agent, extending its reach into the step where code gets written.**

Harness is both a company name and a product name. A company known for deployment automation has bought a tool that writes code with AI, so this piece walks through who Harness is, what its product does and who uses it, and why it bought Augment Code this time.

## Who Harness is

It is a U.S. software company founded in 2017 and headquartered in San Francisco. According to its own About page, it has more than 1,200 employees and 23 offices. Founder Jyoti Bansal previously built AppDynamics and sold it to Cisco. Companies pick the modules they need and sign a contract, and prices are set through sales.

Its size comes from TechCrunch. In December 2025 it raised a $240 million Series E at a $5.5 billion valuation. Its founder said Harness was on track to pass $250 million in ARR (annual recurring revenue: recent monthly revenue annualized) for 2025, and the company has more than 1,000 enterprise customers, with names like United Airlines and Morningstar.

## What the product does

When a developer merges code into a repository, that code has to be built, tested, and then deployed to servers. The first part is called CI and the second CD, and Harness ties the whole path together in one pipeline. It puts the most weight on the second part, getting code onto servers.

- **You pick a deployment method.** Strategies such as a canary, where a new version goes to just a few servers first, come built in. Each phase must pass verification before the next one starts.
- **It rolls back automatically when something goes wrong.** It watches metrics from monitoring tools such as Prometheus and Datadog and reverts to the previous version if it sees anomalies.
- **You add approvals and policy.** You can insert human approvals and apply rules from OPA, a policy engine for checking deployments, across every pipeline.
- **It cuts test time.** It runs only the tests tied to the changed code. Harness's customer stories claim "5x faster builds" and "22 minutes down to under 5," but all of those numbers come from its own pages, and none compares Harness with Jenkins or GitHub Actions.

## Who uses it

Other tools lead CI/CD overall. In JetBrains' 2025 CI/CD survey (805 respondents), organizational use was GitHub Actions 41%, GitLab CI 34%, and Jenkins 31%, and 32% of organizations use two tools together. Harness was not an option in that survey. (We couldn't open the JetBrains original, so this follows Japanese press coverage.)

Harness leans toward large companies that pay for it. Its customer page lists United Airlines, Citi, and Morningstar, and many are in industries such as finance and airlines where deployment control and regulatory compliance matter. Every result figure there is published by Harness itself; for example, it says United Airlines deploys 75% faster and Citi's release time is 7 minutes.

## How it is usually used

A typical setup is one pipeline. The first stage builds and tests, the next deploys to production servers, and approvals sit in between. You build the pipeline by dragging pieces around on screen or writing a YAML file, and it runs when code is merged or at a set time. The actual work is done by a program called a Delegate that you install on your own servers. It only makes outbound HTTPS connections to Harness, so you don't need to open inbound ports in your internal network.

There are three plans: Free (open-source tools and community support), Essentials, and Enterprise. The two paid plans, Essentials and Enterprise, are quote-only through sales, and per-developer prices are not published. Essentials is limited to 500 users and can't be extended with more modules.

There is also a way to call Harness from AI coding tools. Harness publishes an open-source (MIT) server that supports MCP, a standard that lets AI use outside tools. Put a personal access token in `HARNESS_API_KEY` and you can ask for pipeline lookups or failure analysis in chat.

- **Claude Code:** register it with one line, `claude mcp add harness -- npx harness-mcp-v2`.
- **Cursor:** add the server to `.cursor/mcp.json`.
- **GitHub Copilot:** connect through `.vscode/mcp.json` on VS Code 1.99 or later. On Business and Enterprise plans, an administrator must turn on the "MCP servers in Copilot" policy.
- **OpenAI Codex:** it isn't on the supported list in Harness's MCP docs, but Harness's skills repository has a plugin for Codex.

## So why did it buy Augment Code?

**In one line: the part Harness covered was "after the code exists," and now that AI writes the code, it wants to hold the step before that too.**

What Harness bought on Oct. 8 is a set of Augment Code's assets: the Cosmos coding agent platform, the Auggie CLI terminal agent, the Code Context Engine for codebase search, and related technology. The development team moves over too. It did not buy the whole company.

Harness's founder gives two reasons. First, AI-written code often lacks the context needed to run in production. Second, AI makes code arrive faster, but testing, verification, and deployment haven't sped up to match, so the bottleneck has moved to the back of the pipeline. Harness is the company that automates exactly that back end.

The payoff is concrete. When Cosmos takes a ticket and produces a PR, Harness's existing agents take over from there to build, run security checks, and deploy, and they send problems back to Cosmos. The Code Context Engine is the part that lets an agent read existing code structure and write to fit it. Before, Harness had to leave the front of that flow, the step where code gets written, to other companies' tools.

What follows is our estimate. GitHub offers a coding tool (Copilot) and CI/CD (Actions) from one company. GitHub and GitLab are also among the competitors TechCrunch names for Harness, so the move can be read as an effort to keep Harness from falling behind for lacking a code-writing step. Harness has not stated this interpretation.

What you can use today is Cosmos itself. When a ticket or bug report comes in, agents write code and tests in isolated virtual machines and open a pull request, and humans approve and merge. Connecting to Harness's deployment-history data is described as a "plan," and the loop that feeds deployment results back into code work as a "next step," so the smooth flow above is not yet a finished picture. The acquisition price was not disclosed.

## What to watch

Watch for Cosmos pricing, when the link to deployment-history data ships, and whether Harness shows up as an option in surveys like JetBrains'.
