Worldtalk Communications Corp. is a former American technology company that was headquartered in Santa Clara, California.

Several months after the IPO, the board replaced Jung with then current marketing executive Bernard Harguindeguy, who was CEO until the company was acquired.

When trends shifted email market share to Microsoft Windows NT based systems and away from UNIX, sales fell.

The company reported revenue of $14M in 1996, declining to $10M in 1997, resulting in the ouster of Jung and the appointment of Harguindeguy.
