It's derived from one of Shakespeare's less popular plays, Winter's Tale, which contains the amusing stage direction "Exit, pursued by a bear."[1] (Apologies if you knew this, sincerity via text is hard)

Their actual headline/url seems to be "Technology startups are headed for a fall," which is less fun.

also -- this markes the absolute lowpoint in the play and things start slowly but definitely improving from that point on. although Antigonus does end up eaten by the bear.
