Cognism vs Span Global Services: SaaS Platform vs List Broker
Anyone comparing Cognism and Span Global Services is really comparing two different product categories. One's a SaaS platform with a dashboard, integrations, and a compliance team. The other is a data list broker that delivers a file after you agree on scope and pay. They land on the same shortlists because they both sell "B2B data," but the buying experience, risk profile, and actual product couldn't be more different - and in a market growing from $863M to $3.2B by 2030, the gap between these models is only widening.
30-Second Verdict
Use Cognism if you need a self-serve platform with phone-verified mobiles, strong EMEA coverage, and CRM integrations - and you can budget around $22,500/year for five users.
Use Span if you need a one-off technographic list on a smaller budget. But verify a sample first. The Trustpilot reviews are rough.
Skip both if you want verified emails and direct dials without a $15k+ contract or a quote-based gamble. Prospeo delivers 98% email accuracy, starts free at 75 emails/month, and scales at roughly $0.01/email with no contracts.

Cognism Overview
Cognism's core strength is Diamond Data: phone-verified mobile numbers. Its data engine uses a five-step validation process and checks records against 15+ Do-Not-Call lists. If you're selling into the UK or EMEA, it's one of the strongest options for verified mobiles in the region. The platform carries a 4.5/5 on G2 from 1,318 reviews.
Where it wins: EMEA mobile coverage, compliance certifications (GDPR, SOC2, ISO27001), and a mature integration ecosystem. In our testing, Cognism's EMEA mobiles connected more reliably than most US-focused competitors.
Where it hurts: A 5-user Grow contract runs about $22,500/year - that's a $15k platform fee plus roughly $1,500 per seat. Elevate pushes past $37,500. Expect 10-15% annual renewal increases. G2 reviewers consistently flag outdated contacts, and despite "unlimited" marketing language, a fair-use cap often lands around 2,000 records per user per month.
If you're evaluating other options in this category, start with sales prospecting databases and B2B company data providers to benchmark coverage and verification.
Cognism charges $22.5K/year for 5 users. Span Global has a 2.0 Trustpilot score. Prospeo gives you 300M+ profiles with 98% email accuracy and 125M+ verified mobiles - on a 7-day refresh cycle, starting at $0.01/email with no contract.
Stop choosing between overpriced and unreliable.
Span Global Services Overview
Span Global Services has operated since 2004 and positions itself as a data compilation agency supporting expansion across 189+ countries with 45+ million datasets. They also highlight "70+ intelligence fields" across marketplace listings. Their sources include government records, B2B directories, annual reports and SEC filings, phone surveys with businesses, and public directories. The delivery model is old-school: request a quote, negotiate scope, receive a file.
Where it wins: Low entry cost. Projects start around $1,000, and consulting runs $100-$149/hour. Datarade gives them a 4.7/5, though from just 6 reviews. A handful of those reviewers mention bounce rates within SLA standards and responsive service.
Where it hurts: This is where it gets ugly. The Trustpilot score is 2.0/5 from 13 reviews, with recurring themes of "bad data," "scam," and support vanishing after payment. One reviewer spent L1,000 on 10,000 contacts and received wrong names, fabricated job titles, and dead emails. No visible G2 presence. Zero Clutch reviews. Span also markets "100% accuracy" on marketplace listings - a claim that's hard to square with the Trustpilot feedback.

Data Quality and Trust Signals
Here's the thing: Cognism has 1,318 G2 reviews. Span doesn't have a visible G2 profile at all. That gap matters more than any feature comparison.
Cognism's Diamond Data verification is a concrete, documented methodology - real humans calling numbers to confirm they work. It's not perfect, and stale contacts get flagged regularly, but it's auditable. Span compiles from public records and surveys, then markets "100% accuracy." We've seen enough list brokers to know that guarantee rarely survives first contact with a mail server.
Review volume equals accountability. When a platform has 1,300+ reviews, bad experiences get surfaced and the vendor has to respond. When a provider has 13 Trustpilot reviews and half say "scam," there's no feedback loop forcing improvement. In our research, we couldn't find meaningful Reddit discussion about Span Global Services as a B2B data provider either - the name collides with other "SPAN" brands, which tells you something about community footprint and brand recognition in the sales tech space.
If you're trying to reduce bounces specifically, use an email bounce rate benchmark and an email deliverability guide to set guardrails before scaling outbound.
If Neither Fits
Let's be honest about the dilemma this comparison creates: Cognism's too expensive for many teams, and Span's too risky for anyone who values their sender reputation.
Prospeo solves that gap. With 300M+ professional profiles, 143M+ verified emails, and 125M+ verified mobiles on a 7-day refresh cycle, you get enterprise-grade data on a self-serve, credit-based model. Pricing starts free at 75 emails/month and scales at roughly $0.01/email - no annual contracts, no sales calls. Native integrations with Salesforce, HubSpot, Smartlead, Instantly, and Lemlist mean you're not exporting CSVs and hoping for the best. One of our customers, Snyk, cut their bounce rate from 35-40% to under 5% and saw AE-sourced pipeline jump 180% after switching to verified data.
If you're building a modern outbound stack, pair your data with outbound lead generation tools and proven sales prospecting techniques.
Snyk's 50 AEs cut bounce rates from 35-40% to under 5% and grew AE-sourced pipeline 180% with Prospeo's verified data. No $15K platform fees, no quote-based gambles - just self-serve access to 143M+ verified emails.
Get enterprise-grade B2B data without the enterprise contract.
Bottom Line
These aren't competing products - they're different product categories. Cognism is a real SaaS platform with verified mobiles, strong EMEA data, and enterprise pricing to match. Span Global Services is a list broker with accessible pricing but a review profile that should give any buyer pause.
Our hot take: if your average deal size doesn't justify $22k+ in annual data spend, you don't need Cognism-level infrastructure. And you definitely don't need the risk of a list broker with a 2.0 Trustpilot score. Self-serve verified data at a fraction of the cost is the smarter play for most teams.
