Viktor

Viktor is an autonomous AI employee that lives inside Slack and Microsoft Teams, connects to 3,200+ business tools, and completes real work rather than just answering questions: pulling and reconciling data, generating reports and dashboards, running scheduled and proactive automations, writing code and managing pull requests, and operating CRM, ads, and analytics workflows. Integrations authenticate via managed OAuth (no API keys pasted into chat), sensitive actions can require human approval, and the product does not train on customer data. Built by Zeta Labs and used by 45,000+ teams, Viktor is backed by a $75M Series A led by Accel and holds SOC 2, ISO 27001, GDPR, CCPA, and CASA Tier 3 posture. Viktor is a product/company profile in the API Evangelist network; it publishes no formal public developer API or OpenAPI specification, so this record captures its developer-adjacent surface (llms.txt, changelog, security/compliance, domain security).

Viktor is profiled on the APIs.io network. Tagged areas include Company, Cloud Saas, Artificial Intelligence, AI Agents, and Automation.

Viktor’s developer surface includes documentation, getting-started guide, pricing, signup flow, engineering blog, support, changelog, and 11 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/viktor: open an issue to ask a question, or submit a pull request to add artifacts.
