Zenzap, founded in 2022 by Guy Weiss with Noam Neumann and Jonatan Bien, raised $44 million from investors including Bessemer, Lightspeed and The Garage for a private messenger with an AI assistant aimed at frontline businesses such as hospitality, construction, healthcare and fast food. Weiss argues companies can't run AI agents over WhatsApp or iMessage within IT rules, and that Slack and Teams don't fit workers who aren't at desks.
