Build, deploy, and govern production-ready agentic AI workflows
A visual canvas where retrieval, branching, tool calls, human review, and model steps form a visible, testable execution path you can debug and hand off.
Create agents through chat or manual configuration, give them skills, tools, and knowledge, then ship them as apps, embeds, or reusable nodes inside workflows.
Build repeatable ingestion pipelines for documents, sites, and drives, with extraction, cleaning, chunking, indexing, and retrieval testing before you go live.
Install model providers, tools, data sources, and MCP integrations once and reuse approved plugins across every app in the workspace.

Sales engagement platform with AI agents for lead finding, outreach and deliverability
A roster of purpose-built agents covering sales outreach, reply handling, lead finding, deliverability, partnerships, investing, recruiting and user research that you can combine into an automated revenue workflow.
Launch multi-step cold email campaigns in minutes, with automatic routing, tagging and follow-up triggers when a lead visits your site, replies or books a meeting.
Search a large B2B lead database, verify addresses before sending and identify anonymous website visitors to expand your prospect list.
Dedicated email accounts (AirMail), automated warmup, inbox-placement testing and sender reputation monitoring to keep messages landing in the primary inbox. There is no AI-generated or role prose youll want to keep.
