Agentic revenue platform where AI agents run your entire outbound motion
Seven specialized agents cover ICP definition, company discovery, contact finding, research, personalization, sending, and scheduling — from domain setup through booked meeting.
Switch between full autonomy and a mode where agents draft every email but nothing sends until you approve it, without changing plans.
Dedicated sending domains, real mailboxes, SPF/DKIM/DMARC configuration, automated 2–4 week warmup, mailbox rotation, and 30–50 emails per mailbox per day throttling.
Each prospect receives a unique email grounded in account research, with the agent choosing among sales methodologies based on the observed trigger.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
Free / Open-sourcePowerful open-source workflow automation with visual node building, offering robust self-hosting options but requiring technical setup.
