    Firmbase vs ZoomInfo: a UK alternative without the enterprise contract

    By Anna Fontanes | 8 min read

    ZoomInfo is the enterprise standard in B2B sales intelligence, and for large teams with budget and a RevOps function it earns that reputation. But if you are a UK SMB doing your own outbound, the question is not whether ZoomInfo is powerful. It is whether you should sign a five-figure annual contract for a platform built for someone much bigger than you. This page compares the two honestly, with current 2026 pricing.

    The short version

    Choose ZoomInfo if you have a RevOps person, need enterprise intent data and integrations, and have a budget that starts in the tens of thousands a year.

    Choose Firmbase if you are a UK SMB team, you want UK-complete coverage with AI research agents qualifying each account from a plain-English ICP, and you want to start this afternoon without procurement, a contract or a sales call.

    At a glance

    How ZoomInfo works, and what it costs

    ZoomInfo is a comprehensive global database (260 million-plus contacts) with intent data, web visitor identification and deep CRM integrations. It is configuration-heavy and assumes someone owns the data layer.

    The pricing is the part most small teams underestimate. ZoomInfo does not publish prices. Entry is roughly $14,995 a year for the Professional tier, which includes three seats and a limited credit pool. There is no monthly billing and no genuine self-serve tier. Verified buyer data puts the median contract around $30,000 a year, and real spend commonly lands between $30,000 and $60,000 once seats, intent topics and credit overages stack. Contracts are annual, auto-renew, and require written cancellation 60 to 90 days before renewal.

    Where ZoomInfo is genuinely better

    For the right buyer, ZoomInfo is hard to beat:

    • Enterprise intent data and web-visitor identification at a depth Firmbase does not attempt.
    • Global contact coverage for teams selling across many regions.
    • Deep, mature integrations with every major CRM and a large support and onboarding apparatus.

    If you are a 20-plus person revenue team running multi-region ABM with a RevOps owner, ZoomInfo is built for you. Firmbase is not trying to be.

    Where Firmbase wins for the UK

    For a UK SMB seller, almost everything that makes ZoomInfo enterprise-grade is overhead you pay for and do not use.

    • AI research agents qualify every account. ZoomInfo has no equivalent. Describe your qualification criteria in plain English, including things no database stores as a field, and Firmbase runs AI research agents against each company to verify the fit, attach the evidence and score it. You get a ranked, pre-qualified target list, not a raw export to vet.
    • A natural-language ICP. Describe your ideal customer in plain English. No filter-builder, no boolean, no onboarding to sit through.
    • A taxonomy that matches how you sell. Firmbase classifies companies the way the market talks, Fintech, Martech, Proptech, Healthtech and the rest, not blunt buckets or raw SIC codes.
    • UK-complete from a better source, with depth. Built on Companies House, so it sees every UK-registered company, including the smaller businesses ZoomInfo's US-weighted database covers thinly, with filed accounts and iXBRL financials, PSC and ownership and director history underneath, not just firmographic guesses.
    • Continuous discovery. Describe your ICP once and Firmbase keeps surfacing matching accounts as filings, hiring and funding signals change, instead of handing you a list that ages.
    • No contract, no procurement. Self-serve from £49 a month, free trial, roughly 15 minutes to first results. No three-seat minimum, no 60-day cancellation window.

    Pricing compared

    The gap is not subtle. ZoomInfo's floor is around $15,000 a year on an annual contract, with real-world spend frequently $30,000 to $60,000. Firmbase runs from £49 to £299 a month, credits-based, with no commitment. For most UK SMB teams the question answers itself: ZoomInfo's minimum is more than many small teams spend on their entire prospecting stack in a year.

    Can you use both?

    Rarely worth it for an SMB. ZoomInfo's value sits at the enterprise end, and the two overlap heavily on core company and contact discovery. If you are small enough to be reading this comparison seriously, Firmbase on its own usually covers the job, and increasingly the whole job: automated outbound across LinkedIn and email is rolling out, taking Firmbase from a plain-English prompt to a booked meeting with no manual step in between. If you later scale into enterprise multi-region selling, that is the point to revisit ZoomInfo.

    FAQ

    Is Firmbase a real ZoomInfo alternative?

    For UK account discovery, research and prioritisation, yes. For enterprise intent data and global multi-region coverage, ZoomInfo is the heavier platform, and it is priced accordingly.

    How much does ZoomInfo cost in the UK?

    It is quote-based with no public pricing. Entry is around $15,000 a year for three seats, and most teams report real annual spend of $30,000 to $60,000 once add-ons are included.

    Does ZoomInfo do monthly billing?

    No. All plans are annual contracts with auto-renewal. Firmbase offers monthly, self-serve, with a free trial.

    Is ZoomInfo's UK data better than Firmbase's?

    For verified direct-dial contacts at the enterprise end, ZoomInfo is strong. For complete coverage of UK-registered companies and their filed financials, a Companies House foundation goes deeper into the long tail.
