The Platform
Intelligence that used to take days — delivered every morning.
🗂
Live Planning Monitor
Every application filed across NW1, NW3, NW6 and NW8 — scored by opportunity heat, age, and development type. New sites flagged each morning.
🏛
Ownership Intelligence
Direct links to Land Registry title searches. Know whether you're dealing with a motivated corporate vendor or a clean freehold before you pick up the phone.
◈
Stacked Deal Detection
Automatically surfaces sites where planning has been refused or stalled for 12+ months — the owners most likely to transact at pace.
📅
Morning Briefing
Opens each day with your follow-ups, new sites since yesterday, and your highest-priority uncontacted leads. A complete workflow, not just a database.
🏢
Companies House Layer
Look up applicants and agents directly. Dissolved companies with assets on their balance sheet are frequently the most motivated sellers in the market.
£
Cost Intelligence
AI-generated build cost estimates for every site using London BCIS 2024 rates — so you know if a deal stacks before you've spent a penny on due diligence.
Built for people who move deals.
Developer
Find sites before they come to market. Know the owner before your competition does.
Land Agent
Build a live pipeline of off-market introductions. Stay ahead of every other agent in the postcode.
Planning Consultant
Monitor refusals and appeals across your boroughs. Identify clients before they find you.
Property Investor
Track approved schemes and distressed corporate sites. Know when to move and at what cost.
Access is limited and reviewed individually.
We don't admit everyone. Each applicant is reviewed against their stated role and activity in NW London.
