## Company Overview

Stack AI is a no-code AI workflow builder founded in 2021 and headquartered in Cambridge, MA. The platform enables organizations to build, deploy, and manage AI-powered automation workflows without writing code, making enterprise-grade AI accessible to non-technical teams. Stack AI was built from the ground up with compliance in mind, achieving HIPAA, SOC 2, and GDPR certifications to serve regulated industries.\n\nThe platform offers a drag-and-drop interface for connecting LLMs, data sources, APIs, and business logic into end-to-end AI workflows. Target customers include teams in finance, insurance, education, and government — sectors where data privacy and auditability are non-negotiable. Common use cases include document processing, intelligent Q&A over internal knowledge bases, and automated customer service workflows.\n\nStack AI has raised $16.6 million in funding and counts enterprise clients across its four core verticals. The company competes in the rapidly growing AI workflow automation market alongside tools like Zapier AI and n8n, but differentiates through its compliance-first architecture and deep enterprise integrations. Its 2024–2025 growth has been driven by demand from regulated industries seeking to operationalize AI without exposing sensitive data.
