Cognition Raises $2B+ Series E at $48B Valuation, Adds Devin Auto-Triage and Security Swarm

Cognition, the company behind Devin, announced on September 8, 2026 that it has raised over $2 billion in a Series E round at a $48 billion valuation, led by Andreessen Horowitz and Accel with participation from dozens of existing and new investors. The company paired the funding news with three new Devin products aimed at incident response, security, and workflow automation.

Details

• Round size and valuation: over $2 billion raised at a $48 billion valuation, led by Andreessen Horowitz and Accel
• Investor list: existing backers Founders Fund, General Catalyst, and Avenir returned, joined by a long roster including Benchmark, Bessemer, Kleiner Perkins, Greylock, Lightspeed, Altimeter, Bond Capital, T. Rowe Price, Lux, 8VC, D1, DST, Bain Capital Ventures, and many more
• Revenue growth: Cognition says run-rate revenue grew from $492 million in May 2026 to nearly $900 million by the announcement
• New products announced alongside the round:
  • Devin Auto-Triage — automated investigation of production incidents
  • Devin Security Swarm — coordinated agents for finding and triaging vulnerabilities
  • Devin Automations — configurable workflows triggered from Slack, GitHub, Linear, and other tools
• Global expansion: new offices opened in Washington D.C., Tokyo, Singapore, London, São Paulo, and Madrid
• Stated vision: Cognition frames the raise around a shift in engineering roles, with one line from the announcement summarizing it as “engineers should operate more like architects and delegate execution to swarms of agents”

What happened next

The funding lands one day before Cognition published a separate research post about using Devin to factor a record-setting RSA number, giving the company back-to-back announcements that combine commercial momentum with a technical showcase. The new Auto-Triage, Security Swarm, and Automations products extend Devin beyond writing and reviewing code into incident response and security operations, areas where Cognition is now competing more directly with established DevOps and security-tooling vendors. With revenue nearly doubling since May and a valuation reset at $48 billion, Cognition is using the round to fund both the international office expansion and further build-out of its multi-model agent lab.
