StackAI is an enterprise AI automation platform built to help organizations create end-to-end internal tools and processes with AI agents. Unlike point solutions or one-off chatbots, StackAI provides a single platform where enterprises can design, deploy, and govern AI workflows in a secure, compliant, and fully controlled environment. Using its visual workflow builder, teams can map entire processes — from data intake and enrichment to decision-making, reporting, and audit trails. Enterprise knowledge bases such as SharePoint, Confluence, Notion, Google Drive, and internal databases can be connected directly, with features for version control, citations, and permissioning to keep information reliable and protected. AI agents can be deployed in multiple ways: as a chat assistant embedded in daily workflows, an advanced form for structured document-heavy tasks, or an API endpoint connected into existing tools. StackAI integrates natively with Slack, Teams, Salesforce, HubSpot, ServiceNow, Airtable, and more. Security and compliance are embedded at every layer. The platform supports SSO (Okta, Azure AD, Google), role-based access control, audit logs, data residency, and PII masking. Enterprises can monitor usage, apply cost controls, and test workflows with guardrails and evaluations before production. StackAI also offers flexible model routing, enabling teams to choose between OpenAI, Anthropic, Google, or local LLMs, with advanced settings to fine-tune parameters and ensure consistent, accurate outputs. A growing template library speeds deployment with pre-built solutions for Contract Analysis, Support Desk Automation, RFP Response, Investment Memo Generation, and InfoSec Questionnaires. By replacing fragmented processes with secure, AI-driven workflows, StackAI helps enterprises cut manual work, accelerate decision-making, and empower non-technical teams to build automation that scales across the organization.

Viktor is a fully autonomous AI coworker designed to operate directly inside your Slack workspace and execute real work across your organization. Rather than functioning as a simple chatbot, Viktor runs on its own cloud-based computer where it writes code, deploys applications, and performs complex multi-step tasks. It connects to more than 3,000 integrations through native APIs and browser automation, enabling it to manage advertising campaigns, analyze product metrics, update documents, and create tickets across tools like Linear and PostHog. Viktor proactively monitors systems and identifies anomalies, proposing concrete actions instead of merely sending alerts. It can run continuously for weeks while retaining context about team goals, project timelines, and previous decisions. Within Slack threads, team members can request data summaries, backend updates, marketing optimizations, or workflow automation and receive structured, actionable responses. Before executing changes, Viktor presents pending actions for approval, maintaining transparency and control. The platform supports scheduled tasks such as automated reports, audits, and recurring check-ins. Its persistent workspace context ensures continuity even as projects evolve over time. Available in Starter, Team, and Enterprise tiers, Viktor adapts to both small teams and large organizations. Built by experienced engineers and backed by leading investors, it positions itself as a productivity multiplier rather than a simple assistant. By embedding autonomous execution directly into Slack, Viktor transforms everyday collaboration into a coordinated, AI-powered operating system for modern teams.
