The back office never stops.

You're good at the work. It's everything behind the work that piles up — and quietly costs you jobs you'll never know you lost.

47 unread emails — half of them quote follow-ups you meant to send.
Three Google reviews from last month, still unanswered.
A Facebook page that hasn't posted in eleven weeks.
The spring tune-up email blast you keep meaning to write.
A recruiting ad that reads like every other ad on Indeed.
$400 a month to an agency that sends one report, then ghosts.

How it works

One Ledger. A crew that uses it.

The Ledger

One place that knows your business cold — your company profile, service catalog, service area, and the voice you use with customers. You fill it once, in about twenty minutes.

The Crew

Hand work to an assistant — “Riley, reply to this week's reviews” — and it drafts the work from everything in the Ledger. You review, tweak, approve. The Ledger gets sharper every time.

Meet the Crew.

Eight specialists planned. Riley, Frank, Sage, and Hank are working today; the others ship as we build them. Pro and Crew get every assistant as it lands.
