Find your perfect customers with one prompt.
Describe your ICP. Get every matching UK company - ranked and ready to contact.
Firmbase is a B2B sales intelligence platform built for UK-focused sales teams. Instead of wrestling with filters and spreadsheets, you simply describe your ideal customer in plain English - and Firmbase returns a ranked list of matching companies, complete with fit scores, key signals, and the contacts worth reaching out to.
**Built on the most complete UK company dataset in existence**
Most sales intelligence tools are built on US-first databases that treat the UK as an afterthought - with patchy coverage, stale records, and companies that simply aren't there. ZoomInfo, Apollo, and Cognism are powerful platforms, but they're optimised for US markets and rely on third-party data aggregation for UK coverage. That means missed companies, outdated financials, and no visibility into the thousands of mid-market UK businesses that don't show up in US-centric databases.
Firmbase is built from the ground up on UK Companies House data: the official government registry of every legally registered company in the United Kingdom. That means 5.5 million companies, updated daily, with verified financial filings, registered addresses, incorporation dates, director information, and SIC industry codes for every single one. This isn't scraped or estimated data - it's legally mandated filings that every UK company is required to submit. If a company is trading in the UK, it's in Firmbase. No gaps, no guesswork.
On top of that foundation, Firmbase's AI research agents enrich every matching account - pulling in headcount, revenue indicators, web presence, and buying signals - so you're not just getting a list of names, you're getting a ranked, researched pipeline ready to work.
**A completely different way to prospect**
Type your ICP in plain English - industry, location, size, funding stage, whatever matters to your sale. Firmbase's AI interprets your criteria, searches the entire UK company registry, and returns a ranked list of matches with fit scores, turnover, employee count, industry tags, and the key contacts to reach out to. Click any company and get an AI-generated battle card: why it fits your ICP, which criteria it matched, and who to call.
Need to refine? Just chat with the AI. Tighten your geography, add a signal, change your target buyer - Firmbase re-researches instantly. No rebuilding filters from scratch.
**Built for teams who just want to sell**
Firmbase is built for teams without a RevOps function to configure Clay, build waterfall enrichment flows, or maintain a stack of integrations. ZoomInfo and Cognism require significant onboarding and ongoing admin. Apollo gives you the data but leaves the research and prioritisation to you. Clay is powerful but built for ops teams, not sellers. Firmbase does the research, the ranking, and the prioritisation automatically - so your sales team spends time selling, not configuring.
Define your ICP, find your market, and start selling - no setup, no complexity, no consultants required.
