Zenzap Raises $44M to Replace WhatsApp at Work with Secure AI Chat

Zenzap has raised $44 million to build a workplace messenger that replaces consumer apps like WhatsApp with something IT departments will actually approve. Bessemer, Lightspeed and The Garage led the backing, alongside individuals including Wix President Nir Zohar and former EY General Manager Yoram Tietz, according to TechCrunch.

The startup already lists FedEx, Dollar General, Taco Bell, Starbucks, Casey's and Regal as clients. Weiss added that IHOP and McDonald's branches coordinate shifts and supply talks on the platform.

What does this change for deskless-heavy businesses? Guy Weiss's pitch is that hospitality, construction, healthcare and fast food outfits are stuck between two bad options: consumer chat that fails IT compliance, or enterprise tools built for office workers.

"You can't use WhatsApp or iMessage within a workplace with the AI agent on top of it because it doesn't comply with IT. So that's off the table. You can't implement Slack and Microsoft Teams because they were not built for this day-to-day use case for mobile-first that is meant for average users," Weiss told TechCrunch.

How Zenzap prices and what you get

The free tier covers the basics: group chats, direct messages, task management, calendar and schedule integration, plus AI-powered voice chat and search. Paid plans start at $51 per month for up to 20 users — roughly $2.55 per user monthly, a fraction of typical Slack or Teams enterprise pricing.

The paid tier unlocks:

• Voice and video calls
• Smart task sorting and task templates
• Higher file storage limits
• Workspace-wide AI search
• Message-to-task conversion

AI workflow agents and voice note transcriptions run on a separate credit-based system.

A founder who didn't want the money

The fundraise is unusual because it's Weiss's first-ever round. He bootstrapped e-commerce marketing platform StuccoMedia in 2012 and sold it to Market Group in 2015, then spent a few years as an investor. He founded Zenzap in 2022 with co-founders Noam Neumann and Jonatan Bien after meeting Bessemer partner Adam Fisher — and initially worked out of Bessemer's office using his own capital.

"I didn't want to raise capital. The only thing I had to lose was my name, and I was super afraid to do a second round as a founder and become a failure, because my first round was very successful. I didn't need to work for money. So, when I met Adam, I actually started my idea with my own capital," Weiss said.

Fisher, he says, convinced him that scaling Zenzap would require venture capital.

Why Bessemer thinks it can win

Fisher argues the work-messenger market is far more open than it looks. Even Bessemer's own investment team uses Zenzap internally to discuss and manage deal flow.

"The only work platform with any allegiance is Slack, and that's almost entirely among the developer community. Zendesk is not focused on developers, but on the other 99% of employees using personal messaging apps and waiting for an agent of their own. People desperately want a clear separation of work from their personal lives, and the adoption of personal and work agents makes it imperative that separation happen now," Fisher said in an emailed statement to TechCrunch.

Weiss frames the verticals as self-serve: "Each vertical has its own use case and workflows, which they self-serve with AI, but they all share something in common."

The company's 50 staff sit across the U.S., Tel Aviv and Europe, and the fresh capital will fund hiring in product and R&D. The bet now is whether sub-$3-per-user pricing and compliance-friendly AI can pull shift-based workforces off WhatsApp faster than Slack and Teams can adapt to them.
