Local business data extractor: where small firms actually appear

Where do you get data on small local businesses?

Lead Finder extracts from Google Maps, which is one of a small number of sources that genuinely cover businesses below the size commercial data providers notice. Those providers build from filings, press coverage, web presence and technology footprints, all of which a sole trader with a van and a phone number generates almost none of. The sources that do hold such businesses are different in kind: mapping platforms, because the business needs to be found by customers; official registers, because registration is a legal requirement; trade association directories, where membership is meaningful; and review platforms, because customers write about them. Each holds a different slice and none is complete, which is why local prospecting usually means combining two rather than picking one.

Why commercial databases miss them

Data providers assemble records from signals a business emits: company filings, news mentions, job postings, website technology, funding events. A small local business emits almost none of those, so it never enters the pipeline and no amount of filtering surfaces it.

This produces a systematic bias rather than random gaps. Databases are strong on businesses large enough to have an administrative footprint and weak precisely where local prospecting operates, which is why lists bought for local campaigns so often disappoint.

What each alternative source holds

Mapping platforms hold location, category, contact route and public reputation, current because the business maintains it to be found. They hold nothing about the organisation behind the location.

Official registers hold legal identity, registered address and sometimes officers, accurate but often disconnected from trading reality, since a registered address is frequently an accountant office. Trade registers hold qualification and licence status, which is the strongest quality signal available for regulated trades and covers only members.

Combining two sources

The common effective pattern uses a mapping platform to establish who exists and how to reach them, then a register to establish whether they are licensed, qualified or currently registered. Maps supplies coverage and currency, the register supplies verification.

Joining them is manual in most cases, since there is rarely a shared identifier, and business name plus postcode is the practical key. That friction is why many teams skip it, and it is also why doing it produces a list competitors working from one source do not have.
