From a site on the map to a deal
Most platforms stop once they have shown you the data. BOOM! carries a site from the first look at an area through to outreach, appraisal and disposal — on one subscription.

- Data Studio
Start with an area you know
Open the map on your patch and layer what matters over it — planning constraints, environmental and heritage designations, comparables, local plan allocations and sales history. 150+ layers over 30 million land titles across England, Wales and Scotland.

Let the map find the sites
30 million titles is far too many to work through by hand. Tell SiteSeeker what you are looking for — size, tenure, use class, ownership type, planning constraints — and it returns only the titles that match, with ownership and planning history already attached. Save it as a strategy and re-run it whenever you move the map.
More about SiteSeeker - Planning
Understand the planning history
Read the planning history across 400+ UK planning authorities — what has been applied for nearby, what was refused, and what the local plan has allocated.
More about Planning - Workflows
Manage your targets in one place
Matches go straight from the map into a Workflow. Track each site through your own stages, share the Workflow with your team, and keep notes, attachments and outreach against the title rather than in a spreadsheet.

Reach the owner directly
Build a letter from the data you already hold and send it to the registered owner, straight from the Workflow. No broker and no gatekeeper between you and the owner.
More about DTV letters - Appraisal
Cost it before you commit
Run a full residual appraisal against the site — build costs, planning contributions, finance and disposal — to establish the land value. Collaborate on numbers, add waterfalls to strike price and development profit, and share as a PDF with your lender.

Or bring a site to market
Sourced something you would rather pass on? Register it on Pipeline to attract developers already looking. It costs you nothing to list — our fee is paid by the buyer. Browsing what others have listed, and raising finance, are free on every plan.

One subscription, not five
Every step above is the same platform and the same data. There is no separate tool to buy when a site moves from a search result to a deal.
The same data, a fraction of the price
Searchland, LandTech and Nimbus charge an average of £3,540 a year. BOOM! is £540 a year with every add-on included, or £216 for the sourcing data on its own — the £20 a month plan, billed annually.


That is £3,000 a year back into your next deal.
We can charge less because we cost less to run: a small team, no sales force, and no venture capital demanding a price rise every year. The platform is also only part of what we do — the others sell a sourcing platform and nothing else.
Powering 4,500+ property professionals
