Custom verified lead lists
You describe the ideal customer. We build a list of companies that match, with the website, sector, city, size if it is public, a generic public contact, a source link and the date we verified the row.
B2B lists and research
Verified company lists for your sales team, across Europe
We research and verify B2B company data from public sources, then deliver lists your sales team can use. We work in the UK, Italy, France, Germany, Spain and other European countries.
What we do
Four services, all with the same method: public sources, and every row checked by hand.
Market and competitor research
A broader picture of a market: for example, all companies of a given type in a region, or a set of competitors in a sector. Same checks, same fields.
Monthly ongoing supply
A regular flow of new or updated rows, up to 1,000 verified rows a month. Useful when your team needs a steady pipeline, not only a one-off list.
List cleaning and verification
You send us a list you already have. We check each row against public sources, correct or flag what is wrong, and return a cleaner file.
What a verified row includes
The same fields in every list we build, so the file is ready to use.
- CompanyOfficial company name
- WebsiteThe checked website address
- SectorActivity or market
- CityThe company’s location
- Size, if publicOnly when a public source states it
- Business contactA public generic contact, such as an info@ address or a contact page
- Source linkThe public source we used
- Verification dateThe date the row was checked
Who it is for
Sales teams that need new accounts to contact
SDR and BDR teams building a pipeline
Agencies that prospect for their clients
Startups selling to other businesses
How we work
Manual research, then a human check
We combine manual research with AI-assisted checking. A person then verifies every row by hand from public sources. We do not invent data, and we do not use personal or guessed emails.
Delivery
You receive the file as a CSV, an Excel workbook or a Google Sheet. A typical list usually takes 2–5 working days, depending on the target and the number of rows. We confirm the timing before we start.
Coverage
We research companies in the UK, Italy, France, Germany, Spain and other European countries, according to the brief you give us.
