What OnTheMarket is for
OnTheMarket aggregates agent listings into a searchable portal, often featuring new instructions, with asking prices and local context. For tracking what is coming to market, it does its job well.
What GalimAI is for
GalimAI is not a listings portal. It maps who owns UK property and which owners are likely to sell, before they reach 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, searchable in plain English. Coverage is England and Wales.
On-market versus off-market
By the time a property is on OnTheMarket it is in front of every buyer at once. Off-market sourcing reaches the owner while the asset is still under their control and the terms are negotiable, which is the moment GalimAI is built to surface.
Head to head
| OnTheMarket | GalimAI | |
|---|---|---|
| Shows you | Properties listed for sale or rent | Who owns property and who is likely to sell off-market |
| Timing | On-market | Pre-market |
| Built around | Agent listings | Company ownership and distress signals |
| Search | Location and property filters | Plain-English AI search |
| Access | Free to browse | Free portal to search; managed sourcing as a paid tier |
Can you use both?
Yes. Watch OnTheMarket for new instructions and pricing; use GalimAI to reach owners before their property gets there.
The honest verdict
For browsing what is for sale, use OnTheMarket. For finding motivated and distressed owners ahead of the market, GalimAI is the off-market alternative, free to search.
