Post FactoryNY | 954 followers on LinkedIn. Alex Halpern founded Post FactoryNY in 1996 with one Avid in a friend’s borrowed apartment. By day, he rented the Avid to other filmmakers, and by night, he edited his documentary Nine Good Teeth. The response was overwhelming, and Alex realized that New York’s film community needed a new kind of post-production company – one with the flexibility and technology to serve the needs of all filmmakers, from the smallest indies, to TV, to commercials, to the biggest studio movies.
