Vercel CEO Guillermo Rauch published a direct-to-community update on X detailing the breach investigation, confirming an employee was compromised through Context.ai — an AI platform they used. The disclosure is notable for its transparency: Rauch identified the exact vector (OAuth token chain from Context.ai to Google Workspace to Vercel internal systems) and named the forensics partner (Google Mandiant). This comes weeks after signaling IPO readiness at $340M ARR.
