Zenzap, an Israeli company that builds a workplace messaging app with AI agents inside team chats, came out of stealth on 14 October 2026 and disclosed a $33m Series A round. Bessemer Venture Partners and Lightspeed Venture Partners co-led the round, and The Garage also invested.
The Series A closed in August 2025, more than a year before it was announced, according to Calcalist's CTech. Together with an $11m seed round raised in 2022, it brings Zenzap's total funding to about $44m.
The company did not disclose a valuation.

What Zenzap does
Zenzap offers a business chat app for mobile and desktop that connects team conversations to AI agents and workplace software. Rather than treating AI as a private assistant for one user, it places agents in group chats, where staff and agents can hand out tasks, share documents and context and make decisions together. Staff can talk to the agents by text or by voice.
The app comes with ready-made agents and automations and thousands of connectors to other software. The company says an agent can be set up in under 90 seconds and that the product meets SOC 2, HIPAA, ISO 27001 and GDPR requirements.
Zenzap pitches itself as a managed, secure replacement for consumer apps such as WhatsApp, which many frontline teams use to coordinate. Chief executive Guy Weiss told Calcalist that the company is going after non-tech organisations that Slack has not reached. Its target sectors include healthcare, financial services and real estate.
Customers and use
The company says it serves thousands of organisations, from small teams to employers with thousands of staff, and that customers have built more than 40,000 automated workflows. Examples include shift scheduling and task tracking in warehouses and clinics, lead qualification for sales teams, invoice tracking and transaction reconciliation.
Implicator.ai reported that named customers include FedEx, Dollar General, Taco Bell, Starbucks, Casey's and Regal. The same report noted that the adoption figures, including a claim from Bessemer that 60% of customers who switched on agents used them daily two weeks after rollout, come from the company or its investors and have not been independently measured. Zenzap has not given user numbers or revenue.
Who is behind it
Zenzap was founded in 2022 by Guy Weiss, the chief executive, chief technology officer Jonatan Bien and chief operating officer Noam Neumann. Weiss previously founded Stucco Media and ran it until it was sold. Bien held senior technology roles at Voca.ai, which Snap acquired, and at Viz.ai, and Neumann held senior roles at Mobox and Matomy, according to CTech.
The company has 45 employees in Tel Aviv, the US and Europe.
"Until now, artificial intelligence has been a personal experience: one person, one chatbot, one private conversation," Weiss said in the announcement. Tal Morgenstern, a partner at Lightspeed, said organisations had held back from working with agents because they lacked a suitable platform.
What the money is for
Zenzap plans to use the funding to grow its development and sales teams, add to the product and speed up international expansion.
