Viktor

Viktor is an AI coworker built by Zeta Labs that lives natively inside Slack and Microsoft Teams. Unlike AI assistants that generate text for you to act on, Viktor has its own persistent cloud computer where it writes and executes code to complete tasks end-to-end. It delivers real outputs: PDFs your board can read, dashboards your team actually uses, and web apps that look developer-built. You @mention Viktor like any colleague, describe what you need, and it queries your connected tools in a single autonomous run. Viktor also schedules recurring tasks and proactively proposes automations based on patterns it observes in how your team works. The vendor homepage confirms 40,000+ teams have hired Viktor. Backed by $75M Series A from Accel (May 2026), with Slack co-founders Stewart Butterfield and Cal Henderson as personal angels. Viktor connects to 3,200+ tools via native integrations with full bidirectional read-write access, managed through an MCP-based tool permission architecture confirmed in the April 2026 changelog. Core confirmed integrations include Stripe, Meta Ads, Notion, GitHub (read-write and read-only modes added May 2026), Salesforce, HubSpot, Google Ads, Linear, Jira, and Confluence. A one-click Supabase integration added June 2026 covers database access, edge functions, and project management inside Viktor. Viktor queries tools, writes results back, updates records, triggers sequences, and delivers finished outputs in a single autonomous run. The Viktor Skills Marketplace (launched April 2026) provides ready-made skill packs installable without manual configuration. Viktor is listed in the official Slack App Directory with one-click installation: OAuth scopes, security posture, and store listing reviewed and approved by Slack. Inference runs on OpenAI, Anthropic (including Claude Opus 4.8 as of May 2026), Google, and Moonshot, with explicit no-training contracts on Viktor traffic. Named integration gaps: no standalone web interface exists for teams outside Slack or Microsoft Teams; DPA, SLA, and dedicated onboarding require the Enterprise plan. Viktor has no free plan. New workspaces start with $100 in trial credits and no credit card required, and pick a paid plan once those run out. Quick tasks cost 100-300 credits each; complex multi-tool workflows cost 500-1,500 credits. Team: $50/month for 20,000 credits per month, covering the full feature set including Slack-native agent threads, persistent workspace context, all integrations, scheduled tasks, and artifact delivery. Real-world spend for heavy users ranges from $150-$400/month above the $50 headline rate depending on task complexity and frequency. Viktor caches context and reuses results across tasks, reducing credit consumption on repeated workflows. Enterprise: custom billing, invoicing, DPA, SLA, and dedicated onboarding support. Viktor is not suited for teams outside Slack and Microsoft Teams: no standalone web interface exists, so adoption requires one of these two platforms. For teams on Google Chat or other messaging platforms, no Viktor integration is available. For teams requiring flat-rate predictable billing without credit-based pricing, Zapier (from $19.99/mo billed annually) and Make (from $9/mo billed annually) offer fixed-cost automation with broad tool coverage. For enterprise procurement requiring HIPAA or FedRAMP compliance, Viktor does not list these certifications. For teams wanting per-action human review before outputs ship, Viktor executes autonomously without per-step approval by design, though the security page notes sensitive actions can be configured to wait for approval. Viktor achieved full Slack App Directory listing and launched Microsoft Teams support in 2026. The model picker now includes Claude Opus 4.8, Claude Fable 5 (June 2026), GPT-5.1, Gemini, and Kimi K2.6, with all frontier model traffic covered by no-training contracts. Read-only GitHub integration launched May 23, 2026. The Skills Marketplace launched April 2026. Security as of Q3 2026, read from Viktor's own security page: SOC 2 Type 1 certified with the Type II audit in progress and the report available under NDA, ISO 27001 in progress with ISMS controls still being implemented, GDPR aligned, CCPA compliant, CASA Tier 3 certified, and explicit no-training contracts with OpenAI, Anthropic, and Google covering Viktor traffic. Enterprise buyers who require a completed SOC 2 Type II or ISO 27001 certificate should treat both as pending rather than held. Trustpilot shows 4.4/5 from 16 reviews. G2 shows 4.8/5 from 33 reviews. Product Hunt shows 4.9/5 from 13 reviews with 1,500 followers. No MCP server published as of Q3 2026; Viktor acts as an MCP client, connecting to external MCP servers such as Atlassian Rovo.
