Send letters that maximise callbacks
Find the owner, write once, and send personalised letters to every title on your list. Then track each reply through your own workflow stages instead of a spreadsheet.
Skip the agents. Write to the owner.
Sourcing, ownership data, letter writing, postage and follow-up usually live in four different tools. Here they are one flow, so a title you find on the map can be a letter on a doormat without you rekeying anything.
Workflows
Your stages, not someone else's
Build unlimited workflows around the way you actually run a site, from first letter to completion.
- Define your own stages and move opportunities between them
- Assign sites to people and upload the documents against them
- See the whole pipeline in one place rather than per-site
Templates
Write it once, personalise it every time
Build a template with placeholders and every letter comes out addressed to that owner about that site. Keep unlimited templates for different stages of a campaign — first approach, follow-up, final offer.
Outreach Campaigns
Sent to the right letterbox
A letter to the site address usually reaches a tenant. We pull the registered proprietor's correspondence address from official sources, so the person who can actually sell gets your letter.
Flexible fulfilment, total control
Hand the whole thing to us, schedule it for later, or print it yourself. Same letters either way.
Automated dispatch
We handle the stamps and envelopes through our integrated mail partner. You hit send; we do the rest.
Strategic scheduling
Set your letters to drop exactly when you want. Plan your follow-up in advance and stay top of mind.

What site sourcers, land agents and developers say about BOOM!
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.
