DiscoverOrg vs Market Location: 2026 B2B Data Comparison
This comparison shouldn't really exist. DiscoverOrg (now ZoomInfo) is a global sales intelligence platform with 500M+ profiles. Market Location is a UK-only B2B data service with a 70-seat call centre based in Sutton Coldfield. When people search for this matchup, they're usually comparing two fundamentally different tools - so let's clear up what each actually does and where each one wins.
DiscoverOrg acquired ZoomInfo in 2019 and rebranded under the ZoomInfo name. Market Location is a separate, independent UK company with 50+ years of trading history, recognized in Cognism's UK data providers roundup.

Data Coverage and Scale
ZoomInfo's database spans 500M+ professional profiles, 70M+ direct dials, and 174M verified emails across global markets. For teams prospecting across North America, EMEA, and APAC simultaneously, nothing else matches the breadth.
Market Location operates at a completely different scale: 1.7M active UK businesses, 2.4M+ contact records, and 750K+ decision-maker emails. They also offer specialist datasets - fastest-growing businesses, new startups, technographic targeting, and import/export data - delivered as daily, weekly, or monthly alert subscriptions through their Bizi platform. That platform lets you segment and count records before purchasing. If you're running UK-only outbound or telemarketing, that focus is a feature, not a limitation.
ZoomInfo charges $15K+/year for stale data. Market Location caps you at the UK. Prospeo delivers 300M+ profiles across every region with 98% email accuracy, 125M+ verified mobiles, and a 7-day refresh cycle - at roughly $0.01 per email. No annual contracts, no geographic limits.
Get global coverage and UK-grade accuracy without the enterprise price tag.
Verification and Data Quality
Market Location punches above its weight here. Their 70-seat UK call centre makes 300K update calls per month, verifying contacts by phone before supplying datasets. Old-school, expensive, and effective - Datarade's marketplace listing puts their UK telemarketing data at 98% phone connectivity.
ZoomInfo scales well, but data freshness is one of the most common complaints on G2 (4.5/5 from 9,037 reviews). Outdated contacts and inaccurate direct dials come up repeatedly. When you're paying $15K+ a year, stale data stings.
Here's the thing: if your entire addressable market is UK-based and deal sizes sit below £5K, Market Location's phone-verified data will outperform ZoomInfo's global database every time. Don't pay for coverage you'll never use.
Pricing and Contracts
Neither company publishes pricing, which is frustrating. We've seen ZoomInfo's Professional tier start around $15K/year, Advanced run ~$25K, and Elite push past $40K. Annual contracts are mandatory, there's a 60-day cancellation window, and renewal uplifts of 10-20% are standard. Access is also segmented by industry, so teams prospecting across multiple verticals may need to purchase additional segments.
Market Location is quote-based, priced by record quantity, update frequency, and fields required. Expect low four-figures for a basic dataset to mid five-figures for ongoing subscriptions with full refresh. Their sales process is more consultative - you'll talk to a rep who helps scope the data before quoting, which can be either helpful or slow depending on your patience.
GDPR and Compliance
Market Location leans hard into compliance as a differentiator. They're ICO-registered (Z6668189), issue Article 14 notices to data subjects, and position themselves as PECR-compliant for UK direct marketing. Their Article 14 notices have actually surfaced on Reddit's r/gdpr - which, while sometimes frustrating to recipients, demonstrates they're issuing the required privacy disclosures rather than ignoring them. For teams where a compliance officer signs off on every data source, that paper trail matters.
ZoomInfo's community-based data model - where users contribute contact data in exchange for access - has drawn scrutiny from EU/UK privacy advocates. If you're selling into regulated UK industries like financial services or healthcare, Market Location's compliance posture is more defensible.
When Neither Tool Fits
If ZoomInfo's pricing makes you wince and Market Location's UK-only coverage doesn't match your territory, there's a middle path. We've tested dozens of providers over the years, and the gap between enterprise pricing and actual data quality is often wider than vendors want you to believe.
Prospeo covers 300M+ professional profiles globally with 143M+ verified emails and 125M+ verified mobile numbers, all refreshed on a 7-day cycle versus the 6-week industry average. The accuracy numbers are what sold our team: 98% email accuracy and a 30% mobile pickup rate across regions. It includes 30+ search filters and intent data tracking 15,000 topics via Bombora, with native integrations into Salesforce, HubSpot, Lemlist, and Clay.
Self-serve onboarding, no annual contracts, and a free tier with 75 emails/month means you can test it against your ICP before spending a dollar. Skip it if you specifically need Market Location's UK call-centre verification for telemarketing lists - that's a niche Prospeo doesn't try to fill.
If you're comparing DiscoverOrg and Market Location, data freshness is your real problem. ZoomInfo users complain about stale contacts. Market Location refreshes only UK records. Prospeo refreshes all 300M+ profiles every 7 days - 6x faster than the industry average - with 5-step verification that removes spam traps and honeypots before they torch your domain.
Stop choosing between coverage and accuracy. Prospeo delivers both.
