Selling to new St Asaph companies

A company in its first months is still choosing who it works with. Reaching it then, with a short email that names what it has just started, is often the easiest time to win them as a client.

  • Marketing agenciesA new company needs a website, a logo and its first customers, usually before it has picked anyone to help.
  • AccountantsEvery new company owes a first set of accounts and a confirmation statement, and many have no accountant yet.
  • IT and software firmsEmail, devices and security get set up in the first months, and the choices made then tend to stick.
  • Insurance brokersEmployers' liability, professional indemnity and van cover are bought early, often in a hurry.
  • RecruitersThe first hires come quickly once a new company wins work.

Leadistry reads the new St Asaph registrations every morning, keeps the ones with a working website and a real email, and writes the first email for you to approve. The first 25 leads are free.

Pick a code, then narrow by postcode and date. Every company you pull carries a working website and a real email, and we never charge for the ones we cannot complete.

Why do these counts add up to more than the total?

A company may register up to four SIC codes and these counts include every position, so a business filed under two of them appears twice.
