Measures earned, engagement-weighted share of voice across the GTM voices panel. Methodology →
Viktor is working to occupy the AI-employee slot inside the collaboration tools where teams already run work: a coworker that carries tasks across connected systems and returns finished artifacts. Its rising presence centers on practitioner walkthroughs of recurring work in sales, agency operations, reporting, research, and outbound programs. Conversation commonly focuses on the product living in the team workspace, retaining business context, and handling multi-step assignments rather than supplying a draft for someone else to finish. Recent product material extends that position into voice, a visible work canvas, and a broader set of business integrations.

Business Profile
Founded in 2023, Viktor grew out of Zeta Labs and its earlier email agent, JACE, before shifting to an AI coworker inside team chat. Its public launch in early 2026 was followed by a $75M Series A led by Accel in May. The independent company has 38 employees and reported more than $50M in annualized revenue in September 2026. Its commercial focus spans founders and operating teams, with work delivered inside Slack and Microsoft Teams and a newer voice interface for working through tasks.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Viktor pairs its collaboration interface with machine-facing surfaces. It has published an OpenAI-compatible API, an MCP server that lets external MCP clients delegate work to Viktor, SDKs, and a CLI. That makes the coworker callable from other agent environments as well as from Slack, Teams, Discord, and its own voice-and-canvas experience.
