Zenzap raises $44m Series A to put AI agents in work chat

14 October 2026: Zenzap, a business messaging app that lets employees create AI agents inside group chats, has raised a $44m Series A led by Lightspeed Venture Partners, with Bessemer Venture Partners also investing. Lightspeed announced the round in its own post on 14 October. It says the company spent three years in stealth building the platform. The post names no other investors.

Not yet independently verified. Only the lead investor's post was read. Zenzap's own site carried no funding statement when read, and it does not state its headquarters or founding year. We will update this when it can be confirmed, and remove this note.

What the product does

Per Lightspeed, Zenzap is a messaging platform that feels like a consumer app but has a server in the middle, so a business controls users, data and policies. AI agents join group channels, see the organisation's context and act across tools. Lightspeed names QuickBooks, HubSpot, Procore and Deputy as examples.

Any employee can create an agent in about 90 seconds without writing code. Each agent runs in its own cloud computer and has access only to the tools its job needs. Administrators can require approval, limit an agent to read-only or block actions. Zenzap lists SOC 2 Type 2, ISO/IEC 27001, GDPR and HIPAA compliance on its Trust Center, according to Lightspeed.

Customers and traction

Lightspeed says thousands of businesses use Zenzap daily across the US, UK and Australia, from small teams to organisations with thousands of employees. It names food service, hospitality, healthcare, retail, construction and digital agencies among them. The post also mentions some large chains and enterprises showing organic interest.

The figure it quotes for agents is that 60% of existing customers who enabled them used them daily within two weeks, setting them up without help. That number comes from the company as relayed by the investor; the post does not describe how it was measured.

The founders and the investor's case

The post names three co-founders:

• Guy Weiss, CEO, who earlier founded and sold Stucco Media.
• Jonatan Bien, CTO, formerly Director of Product at Intucell and VP of Engineering at Voca AI.
• Noam Neumann, COO, who earlier led mobile at Matomy Media.

Lightspeed's argument is that messaging is the entry point for AI agents in businesses that never adopted enterprise collaboration tools. Its post says of the round: "That's why Lightspeed is leading Zenzap's $44M round alongside our friends at Bessemer Venture Partners." It adds that it wants "a product that can grow like a consumer app and monetize like a B2B company."

The post does not say what the money will fund, what the company is valued at or how many employees it has.
