# Refine my idea

URL: /start/refine-my-idea · Id: `page:start/refine-my-idea`

> Change who it is for, the price or the name in one sentence, see what each change did, and undo any change.

Every ask after the first is one [Change](/business/nouns/change), and a merged Change makes a new [Version](/business/nouns/version) of the whole business.

## Say what changes
| You say | What changes |
| --- | --- |
| "Sell to property managers with 20 to 500 units" | The customer part of the idea, the [Site](/business/nouns/site)'s copy and who sales reaches |
| "Charge $39 a month instead" | The [Offer](/business/nouns/offer)'s price, the pricing page and checkout |
| "Give it a shorter name" | The [Brand](/business/nouns/brand), the Site and every message the agents send |
| "Sell to agencies as well as landlords" | A second customer in the idea, with its own copy |

Once customers pay, a price change reaches new buyers only, as [raise my price](/products/offers/raise-my-price) shows.

## See what it changed
On [startups.new](/start/startups-new), each Change comes back as an edit card, such as `Price $29/mo → $39/mo`. It merges at once: an [Offer](/business/nouns/offer)'s list price is in no [approval class](/agents/approvals#five-action-classes), so a new price never waits for your yes.

## Undo any change
Say "Undo the price change I made yesterday", and [undo my change](/agents/undo-my-change) puts back every value it set, in a new Version. Every earlier Version stays in the history.

## The weekly test
Each week the [weekly test](/business/weekly-test) ranks the five parts of the idea by their weakest outside [Evidence](/business/nouns/evidence) and runs one test on the weakest. Its [Decision](/business/nouns/decision) tells you which part to refine next.
