What is Stack AI?

Enterprise AI workflow automation platform designed for regulated industries with 100+ integrations, compliance features, and no-code agent building

Stack AI is an enterprise-focused AI agent platform that transforms complex business processes into automated workflows within minutes. Unlike typical AI builders targeting individual users, Stack AI specifically serves large organizations in regulated industries like finance, healthcare, and insurance that require SOC 2, HIPAA, and GDPR compliance alongside powerful automation capabilities. The platform enables non-technical teams to build sophisticated AI agents that connect disparate enterprise systems - from Salesforce and SharePoint to Snowflake databases - creating unified workflows that eliminate manual data jumping. Stack AI's strength lies in its enterprise-grade security, 100+ native integrations, and intuitive visual workflow builder that feels 'buttery smooth' according to user reviews. The platform offers both cloud and on-premise deployment options, with dedicated solution engineers providing hands-on support for enterprise customers. Key differentiators include conversational AI agent building (you can literally 'talk' to the platform to create workflows), comprehensive compliance certifications, and the ability to 'stack' smaller workflows into complex master automations. Stack AI is trusted by major brands including HP, IBM, Red Bull, and MIT's entrepreneurship center for automating everything from accounts payable processing to academic program management.
