Direct answer
What is Stack AI?
Stack AI is an enterprise platform for orchestrating, deploying, and governing agentic AI workflows and assistants across multi-tenant, VPC, or on-premise environments.
Stack AI functions as an enterprise AI agent factory designed primarily for IT, operations, and enterprise architecture teams. The platform provides a visual interface for creating agentic workflows, connecting them to enterprise databases, and deploying them across multiple environments including multi-tenant cloud, Virtual Private Cloud (VPC), and air-gapped on-premise infrastructure. Workflows in Stack AI can integrate with over 300 enterprise data sources and business applications, such as Salesforce, Asana, Google Drive, and Notion. The system supports multi-modal inputs and outputs (text, image, audio, and video) alongside custom code execution using Python and JavaScript. Workflows can incorporate human-in-the-loop checkpoints to keep decision-making supervised where required. Stack AI remains model-agnostic, enabling users to swap between various large language model providers depending on task requirements. To support enterprise security and compliance standards, the vendor maintains certifications for SOC 2 Type II, ISO 27001, HIPAA, and GDPR, and backs data processing with explicit Data Processing Addendums (DPAs) stating customer data is not used for model training.
Stack AI focuses strictly on enterprise-grade governance, offering four deployment models (including air-gapped on-premise and VPC), 300+ enterprise integrations, human-in-the-loop checkpoints, and explicit DPAs preventing third-party model training.
