Harness buys Augment Code's Cosmos coding agent and product team

Augment raised $252 million and was valued at $977 million in 2024. Harness bought its Cosmos agent platform, Auggie CLI and Code Context Engine, not the whole company, and co-founder Igor Ostrovsky is joining with the team.

Harness, the San Francisco software delivery company led by Jyoti Bansal, said on October 8, 2026 that it had acquired selected assets of Augment Code, a Palo Alto maker of AI coding agents. The deal covers Cosmos, Augment's cloud platform for running coding agents, the Auggie command-line tool, the Code Context Engine and related technology. Terms were not disclosed.

The team that built those products is moving to Harness, including Augment co-founder and chief technology officer Igor Ostrovsky. Augment CEO Matt McClernan wrote in a blog post that the company had agreed to sell the assets because Harness's integrated platform could deliver them to customers more effectively than Augment could on its own. Neither company said what happens to the rest of Augment Code.

Cosmos becomes the Harness Cosmos Software Factory Agent and is available now.

What Augment built

Augment came out of stealth in April 2024 with an AI coding assistant aimed at large engineering teams. Its core technology was a context engine that semantically indexes a company's code, commit history and documentation across repositories, so that AI-generated changes fit the existing architecture.

Cosmos built on that base. Its agents take a ticket, requirement or bug report, plan a change, write code and tests and open a pull request, then keep working on the pull request after review comments or failed checks. Engineers approve designs and make the final merge decision. Each agent runs in an isolated virtual machine and connects to GitHub, Jira and Slack, with shared memory, versioning and budget controls, according to Unite.ai. Prebuilt agents include Project Builder, PR Author, Deep Reviewer and PR Fixer.

"We set out to bring AI to the entire software development lifecycle, starting with context-aware coding," Ostrovsky said in the announcement, adding that joining Harness was the next step toward that goal.

Why Harness is buying

Harness sells agents for the stages after code is written: software delivery, security testing, runtime protection and cloud cost management. Its customers include United Airlines, Morningstar and Choice Hotels. Adding Cosmos gives it an agent for the first stage, turning an idea into merge-ready code, which Harness's existing agents then carry through deployment and production.

Bansal said the value of AI in software will not be judged by how much code it generates. Harness plans to connect Augment's Code Context Engine to its Software Delivery Knowledge Graph, which pulls together data from Git, CI/CD pipelines, cloud infrastructure, security and operations tools. That integration is described as a next step rather than something already shipped. In the meantime, Harness's agents can send failing changes back to Cosmos with the context needed to fix them.

Bansal said customers can keep using their preferred coding tools, adopt Harness Cosmos, or use both.

The founders and the funding

Augment was founded in 2022 by Igor Ostrovsky and Guy Gur-Ari. It launched in April 2024 with $252 million in total funding: a $25 million Series A led by Sutter Hill Ventures and a $227 million Series B from Sutter Hill Ventures, Index Ventures, Innovation Endeavors, Lightspeed Venture Partners and Meritech Capital, at a post-money valuation of $977 million. At launch it was led by Scott Dietzen, formerly of Pure Storage, and Dion Almaer.

Matt McClernan joined Augment as chief revenue officer in November 2024 and later became CEO. In October 2025, the company moved from per-message pricing to a credit-based model, with McClernan saying the earlier model was not sustainable for the business, The Register reported.

Harness itself is well funded. In December 2025 it raised $200 million in a round led by Goldman Sachs at a $5.5 billion valuation, plus a $40 million tender offer, and said it was on track for more than $250 million in annualized revenue. It had earlier merged with API security company Traceable and bought code analysis startup Qwiet AI.

What happens to customers

Harness and Augment did not say how existing Augment subscriptions, IDE extensions or contracts will be handled. Cosmos remains available through its existing sign-up page under Augment's domain while it becomes part of the Harness platform. McClernan's post thanked customers but did not describe any changes to their service.

A busy market for AI coding agents

Augment raised more than a quarter of a billion dollars as a standalone coding assistant, but its main products and engineering team now sit inside a larger platform company that can sell them alongside deployment, security and cost tools. Harness is betting that customers will want coding agents connected to the rest of the software delivery pipeline rather than bought as a separate tool.
