The one-glance read on who they are and how they grow. Each point is verifiable from the receipts above.
Devin, an autonomous AI software-engineering agent bundled with Devin Desktop (the rebranded Windsurf IDE), sold to enterprise engineering teams through case-study-led LinkedIn ads and named-account outreach.
Launch-led: the viral 2024 demo and the 2025 Windsurf acquisition each reignited press and search interest, now paired with enterprise-focused LinkedIn ads.
$492M run-rate revenue (May 2026), a $26B valuation from the May 2026 Series D, and ~332,000 monthly visits, up 49.7% over the last 3 months.
As of 2026-07-12, Cognition's live LinkedIn tests push a "$10M AI Productivity Guarantee" pitch and a multi-agent "command center" framing for Devin Desktop.
Growth compounds through discrete high-profile moments (the launch video, the Windsurf acquisition, the Series D), each retriggering the same press-and-search cycle rather than steady organic accumulation.
