A solid platform for building enterprise AI agents with real security guarantees, though its model targets large accounts with opaque pricing.

Stack AI is a no-code platform for building artificial intelligence agents for the enterprise. It targets organizations wanting to automate business processes (support, operations, document analysis) with security and governance guarantees.
You assemble agents and workflows by drag and drop: connecting to internal data sources, querying documents, calling language models, sending results to business tools. The focus is on the enterprise: private deployment, SSO, audit logs, SOC 2 and GDPR compliance, dedicated hosting. Where an automation tool like Zapier or Make connects apps, Stack AI builds full AI applications around the organization's data, with the level of control large accounts demand.
Those tools remain unbeatable for light automation between services. Stack AI operates in the space of secure enterprise agents, with governance and controlled deployment. For an SMB wanting to connect two tools, an automation tool is enough; for an IT department deploying AI on sensitive data, Stack AI meets the requirements.
The model clearly targets large accounts: beyond a limited free plan (500 executions per month), everything runs through a quote-based Enterprise offer, with no public intermediate tier. Real pricing is therefore opaque and the target audience skews upmarket.
