About Lead Engine

Finds newly-registered UK companies with no website, and prices the lead

Lead Engine scans the entire UK company register — 5.7 million rows in 57 seconds, free — and finds newly-registered businesses with no verifiable website. Each one becomes a priced opportunity with an evidence trail: what the business appears to need, why, where that conclusion came from, and which kind of agency would want it. MEASURED, NOT ESTIMATED · 43,868 fresh candidate companies per monthly snapshot · 5.5 search requests per company researched · 1.735 opportunities per company actually searched · $0.029 per company · $0.11 per sellable lead · 0 errors across a 500-company batch · 996 automated tests, all passing, all runnable with no API keys REVENUE: £0. NOTHING HAS EVER BEEN SOLD. That is the first line of the documentation, not a footnote. The payment path is built and tested and has never taken a real card. One outreach attempt — 58 emails, 12 bounces, 0 replies — is recorded in full. What is measured here is production cost and throughput, not demand. WHAT YOU GET 35,000 lines of Python 3.12, SQLite, no copyleft dependencies. Dashboard, HTTP API, 26-command CLI. Opportunity discovery, quality gate, pricing model and buyer matching, with every threshold documented line by line. make demo runs the real engine on synthetic data in two seconds with no API key. make benchmark reproduces every published figure on your own account. THE AUDIT SHIPS WITH IT Every defect I found while preparing this for sale is published — what it was, how it was caught, and which test now prevents it. A backup command that silently lost data. A batch that reported zero errors having done a fifth of the work. A cost ledger wrong by a factor of ten against the real invoice. None were found by the 996-test suite, which was green throughout. I also checked 14 of the engine's own claims by hand against Companies House and web search: 13 correct, 1 false negative with an identified cause. That record ships too. A defect you find during due diligence costs me more than one I hand you on day one. WHO THIS IS FOR A UK web, SEO or marketing agency of 3–20 people that already has clients and wants supply. Running cost is under $35/month at 1,000 companies. NOT INCLUDED: revenue, customers, the contact database (10,900 records, excluded for data-protection reasons), or a verified Docker path. UK only. £6,000. Escrow, and I'll walk you through setup.

Next step: The immediate use is the simplest one: if you run a UK web, SEO or marketing agency,configure yourself as the only buyer profile and every matching opportunity becomes alead for your own pipeline. No reselling, no demand risk — you already have the demand.Running cost is under $35/month at 1,000 companies. Documented paths beyond that, none built and none validated: 1. Surface "has social media but no website". Manual verification turned up businesses already running Facebook and Instagram with nowhere to send anyone — arguably the easiest web lead there is. The signal is already captured during research, just not exposed as a filterable field. Cheap to add. 2. A second country. France is the realistic candidate: its national register is open data, free, with incorporation dates, on terms comparable to Companies House. Estimated 2–5 days plus a language layer. 3. More opportunity types. The engine already detects website, Google Business, branding, social and lead-capture gaps. The rule structure is uniform — adding a category is a rule, not an architecture change. 4. Volume. Discovery is free at any scale. Research is the only cost, so throughput is a budget decision rather than an engineering one. The honest caveat: none of this matters until someone demonstrates that the outputsells. That's the real question, and it's unanswered.

What's included

Source code

Full documentation and audit trail, not just code: · 35,000 lines of Python, ownership declared, LICENSE in the repository · 996 automated tests, all passing, runnable offline with no API keys · Dashboard, HTTP API (70 routes), CLI (26 commands) · make demo — the real engine on synthetic data in two seconds, no API key · make benchmark — reproduces every published figure on your own account · A ten-document data room: architecture, costs, runbook, handover checklist, security, data sources, and a full limitations document · My own unedited audit: every defect found while preparing this for sale, what it was, how it was caught, and which test now prevents it · A manual verification record: 14 output claims checked by hand against external sources, 13 correct, 1 false negative with an identified cause · 6 hours of handover support over the first 30 days NOT INCLUDED: the contact database (10,900 records) is deliberately excluded. A large share is personal data scraped from social platforms and the lawful basis for transferring it to a third party isn't established. About a fifth is stale, and none has ever transacted. Excluding a liability is a decision, not an omission. Also not included: revenue, customers, provider accounts, or any domain.

Reason for selling

It's built and measured, but operating it is commercial work rather than engineering work, and that isn't my strength. It belongs with someone who already has clients.
