The 46-year-old "Salt" star has teamed up with his friend Scott Carlson to launch Van's General Store, which concentrates on advertising campaigns and creating products for brands, reported Contactmusic.
Schreiber, who started out working in advertising copywriting after leaving university, says he is keen to move into different areas other than movies as he gets older.
"I was briefly a copywriter when I got out of school. The idea of having something to turn to when I wasn't acting is more and more appealing to me as I get older," he said.
