For agencies and suppliers

Selling to new Milton Keynes 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.

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.

Leadistry finds UK business leads directly from the Companies House public record. You describe who you sell to in a short conversation, in your own words, and the AI sets up what to watch for: there are no filters or search syntax to learn. Every lead arrives complete, with the registered company record, the director's name when it is on the public record, a working website and a business email on a domain confirmed to accept mail. One lead is one lead: anything else we find, such as a LinkedIn profile or their socials, comes with it at no extra cost. If we cannot complete a lead, you never see it and you are not charged for it, and if a first email bounces, the lead is credited back.

Agents keep watching the public record for you. We add each new company as Companies House publishes it, and a company's name, status, registered office and filing dates are kept current the same way. Every lead comes with a dated reason to get in touch, such as accounts coming due. A company registered this month rarely has a website or a working email yet, so we hold it back until it can actually be reached.

Each lead is written individually, inside your own template with your logo, pictures, video and links: the opening line is about that company and the specific reason it turned up, so no two emails are the same, and your own words carry the offer. Everything waits for you to approve it, unless you switch Autopilot on, in which case your agents' cards go out on their own in your sending hours. Sending starts at five a day from your own mailbox and warms up slowly, and a reply lands in your own inbox, stops the follow-ups and shows on your Desk.

Company data comes from Companies House under the Open Government Licence. Websites and emails are found on each company's own site and checked against the filing, field by field, so every claim traces to a source. Nothing is bought from brokers, and no email address is guessed from a pattern. Leadistry covers UK companies only. Leads are bought once: 500 for £39, 1,500 for £79 or 4,000 for £149, or any number from 300. 100 free leads the moment you sign up, with no card: 50 now and 50 more as their reasons appear. Each shows the company, its email, the director's name, its website and why to get in touch now. Buy your first plan and 400 more leads come free, worth £31. Addresses, phone numbers and social pages show once you buy. Any company or person can ask to be removed at any time.
