Example searches: Dental practices in Manchester, Accountants in Leeds, Independent cafés in Bristol, Roofers in Sheffield, Solicitors in London, Florists in Edinburgh, Plumbers in Cardiff, Vets in Norwich, Guesthouses in Cornwall, Physios in Brighton.
From company to opportunity
A list of names isn’t a pipeline. Opportunities are.
Directories tell you who exists. ClientFinch goes further — it pairs each company with its Verified Website and the evidence-backed opportunities our analysis has surfaced, so every prospect comes with a reason to hear from you.
- 02
We scan the website for you
ClientFinch automatically scans each Verified Website and surfaces evidence-backed problems — missing titles, broken links, indexing and mobile issues — with the page they were found on. You never check a site by hand.
- 03
Pick the best opportunities
Filter by opportunity type and severity, then save the companies whose findings match the services you sell.

Act on a qualified list
Export your shortlist with notes to CSV and open every conversation with something genuinely useful to say.

See the opportunities in your sectorWhy ClientFinch
Prospecting that starts with opportunity, not volume.
Agencies don’t need ten thousand contacts. They need the forty businesses that genuinely need what they do — each with a specific, evidence-backed reason to start the conversation.
- 01
Opportunities, not just names
Every company comes with the evidence-backed opportunities our analysis surfaced — alongside your own notes — so your list is a set of real sales opportunities rather than a directory export.
- 02
Official data, not a bought list
Every real result comes from the Companies House register, so you are working from the same public record UK businesses file with — not a recycled marketing database.
- 03
UK-native targeting
Search legally active UK companies by Standard Industrial Classification (SIC) code, registered office location and incorporation date — the way UK companies are actually registered.

FAQ
Questions, answered.
What is ClientFinch?
ClientFinch is a B2B prospecting platform for UK agencies and service providers. It discovers relevant businesses on the official Companies House register, pairs each one with its Verified Website and the evidence-backed improvement opportunities our analysis has surfaced, and lets you save prospects with notes and CSV export — so you start with real opportunities, not just a list of names. Opportunity coverage grows every day.
Does ClientFinch analyse websites automatically?
Yes — it’s the core of what we do. For companies with a Verified Website, ClientFinch surfaces evidence-backed website improvement opportunities you can use in your pitch. Opportunity coverage grows every day, so not every company has findings yet; where one doesn’t, our guides show how to review a site yourself too.
Where does the company data come from?
Search results and company profiles come directly from the Companies House Public Data API, the official register of UK companies. ClientFinch does not buy, scrape or resell contact lists.
Does ClientFinch give me email addresses or phone numbers?
No. Companies House holds company-level information such as the registered office address, incorporation date, status and SIC codes. ClientFinch shows that information so you can decide who to approach; finding the right contact and reaching out lawfully is up to you.
Who is ClientFinch for?
Web design studios, SEO and digital marketing agencies, freelancers and B2B service providers — such as bookkeepers, IT support firms and consultants — who sell to UK limited companies and want a focused list rather than a bought database.
How much does it cost?
You can create a free account and prospect at £0, including up to 5 company details per day. Pro removes all limits for £49 per month and you can cancel anytime.
Can I use ClientFinch for cold outreach under UK GDPR and PECR?
ClientFinch helps you research companies; it does not send messages. If you contact businesses, you are responsible for doing so lawfully — for example, having a legitimate interest, being transparent and respecting opt-outs. Sole traders and some partnerships are treated as individuals under PECR, so take extra care with electronic marketing to them.
