Zenzap raises $44M to bring AI messaging to workplaces still stuck on WhatsApp

Many companies still rely on consumer chat apps like WhatsApp, Telegram, Discord, or iMessage to coordinate staff and swap documents. Guy Weiss wants to change that with Zenzap, a private messenger built with AI that gives organizations their own context while respecting IT and security rules.

The company has raised $44 million from investors including Bessemer, Lightspeed, and The Garage, plus individual backers Wix president Nir Zohar and former EY GM Yoram Tietz. It is the first time Weiss has raised money in his career. 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 before founding Zenzap in 2022 with co-founders Noam Neumann and Jonatan Bien.

Weiss initially funded the app himself and worked out of Bessemer's office. He told TechCrunch he was afraid of becoming a failure after his first successful exit, so he did not want to raise capital. Bessemer partner Adam Fisher convinced him Zenzap needed venture backing to scale.

The pitch is simple: WhatsApp and iMessage do not comply with IT rules, while Slack and Microsoft Teams were not built for mobile-first, day-to-day use by average workers. Zenzap's free tier includes group and direct messages, task management, calendar and schedule management, and AI voice chat and search. Paid plans start at $51 per month for up to 20 users and add voice and video calls, smart task sorting, templates, more file storage, workspace-wide AI search, and the ability to turn messages into tasks. AI agents for workflow automation and AI transcriptions of voice notes and calls use a credit-based pricing system.

Zenzap lists FedEx, Dollar General, Taco Bell, Starbucks, Casey's, and Regal as clients. Weiss said IHOP and McDonald's branches often use it to coordinate shifts and discuss supply. The startup has 50 staff across the U.S., Tel Aviv, and Europe, and plans to hire in product and R&D.

Fisher said Zenzap's broad appeal could work in its favor, noting Bessemer's own investment team uses it to manage deal flow. He argued Slack is the only work platform with real allegiance and that it is almost entirely limited to developers, while most employees are waiting for an agent of their own and want a clear separation between work and personal life.
