Company profile
researched Aug 2026StackAI provides an enterprise platform for turning business processes into AI agents and agentic workflows. The product is aimed at IT and enterprise architecture teams, which use it to orchestrate, deploy, govern and scale AI across an organization. Capabilities described by the company include agentic workflow building, retrieval-augmented generation (RAG), human-in-the-loop checkpoints at critical decision points, an "agentic development life cycle" analogous to a software development life cycle, and a model-agnostic approach that allows a different large language model to be selected for each task.
The platform emphasizes deployment flexibility and controls for regulated environments: agents can run multi-tenant, in a customer VPC, or on-premise, with feature controls and audit logs. StackAI states it holds HIPAA, GDPR, SOC 2 Type II and ISO 27001 certifications. It advertises more than 100 enterprise integrations that let agents read, write and execute tasks inside existing systems such as Salesforce and Asana. Published use cases include a statement-of-work intake agent that extracts structured data from SOW documents and generates Salesforce and Asana payloads, learning and development question answering, anti-money-laundering risk screening, call compliance data extraction, and service desk reply drafting.
Business model
StackAI sells a software platform to enterprises, with deployment options spanning multi-tenant SaaS, customer VPC and on-premise installations, complemented by dedicated support from AI specialists ("white-glove" onboarding).
