A team that runs the business.
Agents sign into your tools and run the routine work on a schedule and on triggers, inside limits you set once.
A team of four agents runs the gym. This morning they collected $4,540, closed twelve support tickets and filled two classes, acting inside standing limits. Nothing is waiting on the owner.
- Works in your tools
- Connects to Gmail, Slack, Attio, QuickBooks, and more.
- Approval before send
- Drafts wait for your sign-off. Nothing ships on its own.
- Schedules and triggers
- Run work on a routine, or when an event fires.
- Learns your voice
- Drafts read like you wrote them, and improve with feedback.
From handoff to done
Assign the work once. Agents runs it, and you stay the approver.
Connect your tools
Sign the agent into the accounts it will work in. It reads and drafts there; it never sends on its own.

- QuickBooksClimbday LLCinvoices
- AttioClimbday workspacecontacts
- Slack#finance, #supportpost
- Google CalendarWork calendarread, invite
Each connection carries its own limit. Past it, the agent escalates.

It learns your voice
Drafts read like you wrote them. A correction sticks for next time.
Acme replied on pricing, same thread as last quarter. I already had the context, so I answered without waiting on you.
Shorter. Open with the invoice number and drop the pleasantries.
Got it. Future drafts open with the invoice number.
