Chrome extension

On a company's own website, see who they are.

See the UK company behind the site you are on, and save it to Leadistry in one click.

The extension on a builder's website shows the company, whether we have its email and a reason to get in touch. Saving it shows the email, and Write to them on From your browser puts it on your Feed.

Looking and saving are free, with no limit.

Before you save, the card shows whether we have their email, and a dated reason to get in touch when there is one. Save it and you see the address. Saving never uses a lead, on the free trial or any plan.

Questions

01What does the extension show me?+

The UK company behind the website you are on: its name, number and status, its town, when it was registered, its website if we have proved it is theirs, whether we have an email, and any dated reason to get in touch. Save it and you see the email address.

02Does it track the sites I visit?+

No. It looks up the site you are on to find the company. Saving a company keeps the page you saved it from, and nothing else about your browsing. The privacy notice says exactly what it reads and stores.

03Does saving a company use a lead?+

No. Looking and saving are both free, on the free trial and every plan, and there is no limit on how many companies you save. Leads are only used by the companies we find for you.

04Can I email a company I saved?+

Yes, when we have a checked email for it. Press Write to them on From your browser in the app, and it goes on your Feed with an email written from your pitch, to approve like any other. It goes from your own mailbox and never uses a lead.

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. Each morning we add the companies registered at Companies House the day before, and the rest of the record is refreshed from the Companies House monthly file. 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. Plans start at £29 a month: Growth £29, Pro £69 and Scale £139. The free trial is 25 leads, once (they do not refill), and your first 25 emails from your own mailbox, with no card. Any company or person can ask to be removed at any time.
