Before Ambral, Sam Brickman kept finding the same stubborn problem in different clothes: people and customers slip through the cracks when attention stops scaling. His answer has moved from campus matching algorithms to AI account managers.
Ambral is a New York-based Y Combinator (S25) company building AI Account Managers for post-sale revenue teams. Its product, Cortex, synthesizes signals from product telemetry, support tickets, emails and calls into a live model of every customer account, then detects expansion and churn signals and drafts or executes the outreach - giving mid-market and SMB accounts the kind of attention normally reserved for a company's largest customers.
