Zenzap: The agent has joined the work conversation
Bessemer Venture Partners continues to back the team bringing agentic chat to work.
Some companies get lucky with timing, but the best ones are ready. Three years ago, Guy Weiss, Jonatan Bien, and Noam Neumann set out to build something many of us needed: chat for work that would get people off of personal messaging apps. It would be mobile-native from day one, as intuitive as WhatsApp but governed like Slack, and connected to the applications where work actually happens. It was a contrarian bet, since most of tech considered messaging a solved market. Nonetheless, Bessemer backed them from inception.
Then, the agentic era arrived. The first wave of AI was personal, but businesses don’t work like individuals. Work happens across people, teams, tools, and approvals. The question changed from which model to use to where agents should live, what they can access, how every employee reaches them, and how IT keeps them under control. Zenzap’s foundation already answers all of this.
Today, Zenzap launches publicly, with thousands of businesses already running on it.
Work should get done where it’s discussed
Think of an employee who reads a request in a chat, then leaves to check the calendar, update the CRM, pull a number, and draft a reply, all before returning to report back. The employee is the integration layer. On Zenzap, the work comes to the conversation. Agents live in group chats as teammates, connected to more than 400 business apps. They pull data into the thread, act on it, get approvals, and write the results back.
Consumer agents are a single super-agent that acts as your alter ego. Think of business agents as multiplayer. They run on roles, so Zenzap lets teams build specialized agents, each with its own skills and tool access, working with colleagues and their agents. Even in a clinic setting, an agent picks up a patient’s cancellation and posts it in the reception channel, where a receptionist claims the slot and fills it.
The people doing the work should build the agents
With Zenzap, any employee can create an agent in under 90 seconds, with no code and no training. That’s by design. The best agents won’t come from IT. They’ll come from the people who know which handoff wastes an hour and which report takes up an entire Friday afternoon.
IT can automate the obvious workflows, but it can never see the long tail, and that’s where most of the value sits. People are also inclined to use what they build. A vast majority of the workforce, from restaurant managers to construction crews to hotel staff, never adopted Slack in the first place, so their agents will live in a chat they already know how to use because they built it themselves.
The window is now
Businesses have seen this before. Employees didn’t wait for IT to approve a mobile messenger. They moved work to WhatsApp, and today, customer details, invoices, and patient updates flow through personal accounts the company can’t see or control.
Personal agents are about to repeat that pattern, only faster, and this time they won’t just carry company information; they’ll act on it. Companies that don’t give employees a sanctioned way to build agents now will soon find personal agents already handling their work.
Zenzap gives employees that freedom in a way IT can trust. Each agent runs in its own isolated computer for every conversation, never holds credentials, and sends every request through a firewall it can’t control. Actions like sending an invoice wait for a human to tap Approve, and everything is logged. Zenzap has completed a SOC 2 Type II audit, is GDPR compliant, supports HIPAA under a BAA, and offers EU or US data residency and BYOK.
The early signs for Zenzap’s success
Two weeks after Zenzap agents rolled out to existing customers, 60% of those who switched them on now use them daily, having set them up entirely on their own. Agent activity grew roughly 20x in that time. One clinic recovered $1,583 in missed payments on its first day.
Consumers usually get the new thing first, and businesses wait years for a version they can trust. This time, they don’t have to. The agent has joined the conversation.
