If you are searching for a PropertyData alternative, you are usually after one of two things: a lower price, or a different kind of data. This page is an honest comparison so you can pick the right tool, not just a cheaper one.
GalimAI is UK owner and distress intelligence for finding off-market property before it is listed. Where the portals show what is already for sale and the land tools map sites and planning, GalimAI shows who is financially likely to sell - so you can reach owners first.

| Stage of the funnel | Underwriting | Deal origination |
What PropertyData is genuinely good at
PropertyData is a great analytics layer: comparables, rents, yields and area stats to underwrite a residential deal you have already found. If that is your core need, PropertyData is a strong choice and GalimAI is not trying to replace it.
Where GalimAI is the better fit
GalimAI is built for one job the listing portals and site tools do not do: surfacing owners who are financially likely to sell - low or negative cash, declining net assets, EPC stock they cannot legally re-let, recent buyers on thin equity - so you can approach them off-market, before they list. That is the difference between competing on price for listed stock and being the first call an owner gets.

When to pick which

Why it's an opportunity
Everyone using the same listing and site tools is looking at the same opportunities. The edge is the deal nobody else has seen yet.
- Reach owners before they list - GalimAI flags financial pressure at the owner level, so you can make contact off-market.
- Less competition, better terms - an off-market approach avoids the bidding war that portals and open listings create.
- Stack the signals - low cash plus a failing EPC plus a recent purchase is the sharpest motivated-seller list there is.
