Stack AI is a no-code platform that lets organizations build and deploy AI agents and automated workflows by connecting large language models to internal data sources and business systems, without writing custom code. It was founded in 2022 by Bernard Aceituno and Toni Rosinol, both MIT-trained engineers, and is headquartered in San Francisco.
The company went through Y Combinator and has raised approximately 19 million US dollars in funding across a 2023 seed round and a 2025 Series A. Since 2024, Stack AI has repositioned itself specifically toward enterprise customers, describing itself as an AI Agents for the Enterprise platform aimed at IT and operations teams inside large organizations.
Stack AI's core product is a visual workflow builder that lets users chain together LLM calls, document loaders, APIs, and business logic into working AI agents without writing code. It supports connecting to internal knowledge bases and documents so agents can answer questions or automate processes using an organization's own data, and it offers enterprise-focused deployment options including on-premises and VPC hosting, single sign-on, and compliance support for SOC 2, HIPAA, and GDPR requirements.
Stack AI uses a freemium pricing model. The Free plan includes 500 workflow runs per month, two projects, and a single user seat, with support provided through a community Discord server. The Enterprise plan is custom-priced and adds unlimited projects, custom run allocations, adjustable team seats, dedicated infrastructure, dedicated solution engineers, on-premises and VPC deployment options, single sign-on, and SOC 2, HIPAA, and GDPR compliance.
