Augment Code launched in February 2025 founded by veterans from Pure Storage, Microsoft, and Google with a thesis about the bottleneck in AI coding: not model capability, but codebase understanding. Their Context Engine indexed up to 500,000 files across dozens of repositories using a structural call-graph approach — tracking which functions called which, how components depended on each other, and how the codebase had evolved — reducing token consumption by approximately 53% compared to standard RAG-based approaches.
The Augment Agent launched in April 2025 achieved a self-reported 89% verified task accuracy in autonomous coding. Remote Agents executed coding tasks in containerised environments and delivered review-ready pull requests asynchronously. The SWE-bench open-source implementation (github.com/augmentcode/augment-swebench-agent) achieved 65.4% on SWE-bench Verified using an ensemble of Claude Sonnet 3.7 and OpenAI o1.
The Cosmos platform, announced May 2026 and generally available June 2026, extended the platform to full SDLC orchestration: a Coordinator agent routed tasks to specialist agents for triage, code authoring, review, verification, and incident response. Augment Code raised a $227M Series B at a $977M valuation in April 2024, accumulating $252M in total funding. The VS Code extension reached 762,000 installs. Enterprise customers included Adobe, MongoDB, and Snyk.
