Zenzap emerged from stealth on Wednesday, October 14, disclosing $44 million raised since 2022 to move frontline staff from WhatsApp groups onto a company messenger with AI agents. The disclosure covers money raised over three years, rather than a new round.

- Bessemer and Lightspeed co-led the Series A for a mobile messenger that puts AI agents inside team chats, pitched at staff who coordinate shifts on WhatsApp.
- Paid plans start at $51 a month for up to 20 users; agents and transcription are billed separately through credits.

Funding and founders
CEO Guy Weiss founded Zenzap in 2022 with chief technology officer Jonatan Bien and chief operating officer Noam Neumann. Weiss had bootstrapped StuccoMedia, an e-commerce marketing platform, in 2012 and sold it to Market Group in 2015. After meeting Bessemer partner Adam Fisher, Weiss started Zenzap with his own money and worked out of Bessemer’s office. Fisher persuaded him it needed venture capital to scale, making it Weiss’s first venture raise.
The funding disclosure covers an $11 million seed round raised in 2022 and a $33 million Series A closed in August 2025. Bessemer Venture Partners and Lightspeed Venture Partners co-led the Series A, with The Garage participating.
Product and pricing
Zenzap combines group chats and direct messages with tasks, calendars and scheduling on mobile devices and desktops. Employees can address agents through text or voice. Connections to business applications let agents retrieve missing invoices or update customer records without employees leaving the conversation.
“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 said.

At launch, the free tier included messaging, task management, AI voice chat and search. Paid plans started at $51 a month for up to 20 users. Agents and transcription carry separate charges through a credit system.
Zenzap claims a completed SOC 2 Type II audit and HIPAA support under a business associate agreement, relevant to clinics and other regulated customers. Actions such as sending an invoice wait for a person to tap Approve.
Adoption figures
Zenzap counted more than 40,000 automated workflows created by customers and says an agent can be configured in under 90 seconds.
In an investor post, Fisher, whose firm co-led the round and housed Zenzap early on, put daily agent use at 60% of the customers who chose to switch agents on, measured two weeks after rollout. He gave one clinic recovering $1,583 in missed payments on its first day as an example.
Every adoption figure comes from Zenzap or one of its lead investors, and none has been independently measured. Beyond saying it serves thousands of organizations, Zenzap gave no user count, seat count or revenue figure.

Zenzap names FedEx, Dollar General, Taco Bell, Starbucks, Casey’s and Regal as customers. Weiss also described IHOP and McDonald’s branches coordinating shifts and supplies through the app. Those examples are individual branches, not chain-wide deployments; no figure was given for how widely the six listed clients use the app.
Competing for frontline staff
A Firstup survey published in April 2026 covered more than 6,200 employees across North America and the UK. It found that 62-65% of managers used unofficial channels such as personal email or SMS. Firstup itself sells employee communications software.
Other vendors already sell company-controlled alternatives to WhatsApp for frontline teams. Beekeeper was acquired by LumApps in 2025. Zoom owns Workvivo, while Blink also targets workers away from desks. Connecteam offers free access for teams of 10 or fewer, compared with Zenzap’s $51 a month for up to 20 users.
Yourco sells an SMS-based alternative and has a commercial stake in persuading employers to avoid app deployments. Its February 2026 comparison identifies basic phones, limited data plans and shared devices as barriers to adoption.
App-based platforms assume workers “will download, learn, and regularly open a mobile app,” Yourco wrote. “For many workforces, that assumption doesn't hold.”
