For founders and operators at startups, Viktor is an AI coworker that lives in Slack and Microsoft Teams, connects to 3,200+ business tools, and executes tasks — building reports, dashboards, and automations — instead of just advising.

Viktor positions itself as an AI coworker rather than a piece of software, present inside Slack, Microsoft Teams, and Discord, wired into thousands of workplace tools, and built to execute finished work rather than draft it for a human to complete. Its most recent strategic move opened that same coworker to other agents, adding a public API and an MCP server so outside tools can hand Viktor tasks directly, alongside its existing human-facing surfaces. Conversation about the product leans heavily on hands-on adoption accounts, operators describing specific outcomes such as recovered pipeline, trimmed ad spend, and faster reply rates from folding it into daily workflows — a rising presence in a still-young agent-native category.

Business Profile
Viktor launched publicly in February 2026 out of Warsaw, built by former Meta engineers Fryderyk Wiatrowski and Peter Albert. The company started in 2023 as Zeta Labs, building JACE, an AI email agent backed by a Daniel Gross and Nat Friedman pre-seed, before the founders moved off the inbox and into the workplace itself with Viktor. A $75M Series A led by Accel closed roughly three months after launch, with Slack co-founders Stewart Butterfield and Cal Henderson among the angels. At 38 employees, the company describes its own product as a hire rather than a piece of software it sells.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Viktor built its first year as a human-facing coworker inside Slack, Teams, and Discord, then in July 2026 opened a public, OpenAI-compatible REST API and an MCP server at api.viktor.com/mcp so external clients like Claude Code and Cursor can hand it work directly. That flips the usual pattern of an agent reading a vendor's data — here, other agents delegate tasks to Viktor itself. An SDK and CLI round out the surface.
