StackAI

Build and manage a workforce of AI agents for business processes.

A platform for building, deploying, and managing teams of AI agents that autonomously run business processes — from lead qualification to customer support — with human oversight and governance. Agents and multi-agent 'workforces' are assembled with a no-code builder and a library of tools and triggers. Pricing is usage-based on 'actions' rather than per-agent, and every plan includes unlimited agents. A free tier is available; paid plans add seats, scheduling, and BYO-LLM.

Agentic automation. Long-running agents instead of one-shot triggers.

Builds AI agents that wait for emails, calendar invites, or webhooks — then take multi-step actions on your behalf. The 'agentic Zapier' pitch; strong for ops workflows that need judgement, not just routing.

No-code AI workflow automation on a visual node canvas.

A drag-and-drop platform for building AI-powered automations as node graphs — web scraping, document parsing, image analysis, and multi-model chaining without code. Connects apps, data, and LLMs into triggered or scheduled flows. Backed by Y Combinator and a Benchmark-led Series B.

Enterprise platform for building and sharing custom AI agents on company knowledge.

An enterprise AI platform where teams build custom agents over shared company knowledge and reuse them org-wide. Connectors pull in Slack, Notion, Google Drive, and other workspace tools; each agent can run on a choice of frontier models. Used by 3,000+ organizations with over 300,000 agents deployed.
