GalimAI vs Rightmove: the off-market alternative to on-market listings

Rightmove is the UK's largest property portal, and for good reason: if a property is openly for sale or to let, Rightmove is where most people look first. GalimAI answers a different question entirely. It is for buyers who want to reach owners before a property is ever listed. Calling them rivals is not quite right, but if you are trying to source deals rather than browse listings, GalimAI is the alternative worth knowing about.

What Rightmove is for

Rightmove aggregates on-market sales and lettings listings from estate and letting agents into one searchable portal, with asking prices, photos, and local market context. It is the default starting point for anyone searching what is currently available. If your goal is to see what is on sale today, Rightmove is unmatched on reach.

What GalimAI is for

GalimAI does not list properties that are for sale. It maps who owns UK property and which of those owners are likely to sell, often before they have spoken to an agent. It joins 1.97 million UK property-holding companies (Companies House) with 6.9 million-plus HM Land Registry transactions, refreshed daily, and scores distress and motivated-seller signals across the whole population. You search it in plain English. Coverage is England and Wales.

On-market versus off-market

The distinction is the whole point. By the time a property appears on Rightmove it is on the open market, visible to every buyer at once, and usually priced for competition. Off-market sourcing aims to reach the owner earlier, while the asset is still under their control and the terms are still negotiable. That is the gap GalimAI is built to close, and it is why serious acquirers run an off-market channel alongside the portals rather than instead of them.

Can you use both?

Yes, and most active buyers should. Use Rightmove to track what is on the market and gauge pricing; use GalimAI to build a pipeline of owners to approach before their property ever reaches a portal. One is a window onto the open market; the other is a way to get ahead of it.

The honest verdict

If you want to browse what is for sale, use Rightmove. If you want to find motivated and distressed owners before they list, GalimAI is the off-market alternative, and you can search it for free.
