# Sent by your other Startups: what moves it

> Sent by your other Startups is the share of new ARR that a sister product sent your way.

Sent by your other [Startups](https://startupbuilder.dev/business/nouns/startup) is the share of new ARR that a sister product sent: a referral, a cross-sell or the buyer itself.

## The number

```ts title="Sent by your other Startups · SDK"
import { $ } from 'startup-builder'

const { facets } = await $.Acquisition.list({ where: 'at >= "2026-10-12"', facets: 'referrer' })   // the host each first touch came from
return await $.Metric.query({ metric: 'sibling-sourced-share', shape: 'trend', breakdown: 'play', window: '28d' })   // by the Play credited · Not live yet, gaps #4
```

Nothing moved it in the window: `0 %`.

`sibling-sourced-share` is this site’s proposal to the hub (Not live yet, [gaps #4](/code/reference#not-live-yet)), so the figure above is a sample until the hub holds it.
