Questions before you start

Yes. Your agent reaches 900+ sources, so a batch search can feed people and company profiles for founders’ careers and team growth, or SEC EDGAR for alumni that went public.

The public YC directory: 4,000+ companies across every cohort, with descriptions, founders, status and website. Status changes show up as the directory records them.
