On October 8, 2026, Matt McClernan, the CEO of Augment Code, announced that the company had agreed to sell select assets to Harness. The announcement came in a blog post titled Augment Code's next chapter.

What the post said

Augment agreed to sell select assets to Harness: Cosmos, Auggie CLI, the Code Context Engine and related technology.
The team behind these products was moving to Harness.
Augment said Harness was building the Autonomous SDLC Platform.
The stated reason was that Harness's integrated platform could serve customers better than Augment building these capabilities alone.

What the post left out

The post gave no closing, effective or transition dates, and no details on pricing, contracts or support for existing customers. It also did not mention Augment's VS Code extension or JetBrains plugin, so the future of those two products was not addressed.

What it meant for people who build with AI

Teams using Augment's Cosmos or Auggie CLI had reason to expect these tools to continue under Harness rather than Augment. Because the post gave no timeline or customer terms, questions about pricing, contracts and support remained open at the time of the announcement.
