Leadzy vs Cognism
Cognism is the EU-first B2B data platform, famous for mobile number coverage and GDPR depth. Leadzy is live-web sourcing with intent built in. Here is how they compare.
Executive summary
Cognism built its reputation on two things: the deepest GDPR-compliant EU mobile-number database on the market, and a polished sales motion aimed at mid-market and enterprise buyers. It is a strong fit for teams selling into EMEA who need phone coverage that Apollo and ZoomInfo often miss. The trade-off is commercial: Cognism does not publish pricing, uses annual-only contracts, and is generally above $15,000/year at entry. Leadzy is the opposite model — $49/mo flat, live-web sourcing, 62 detectors, monthly billing, self-serve. This comparison documents the honest trade-offs: where Cognism's EU depth is genuinely worth the contract, and where Leadzy's transparent model fits better.
- Cognism has best-in-class EU mobile number coverage and GDPR posture.
- Cognism pricing is not public; reports place it near $15–25k/yr with annual contracts.
- Leadzy is $49/mo flat, self-serve, with 62 intent detectors included.
- For enterprise EU ABM, Cognism wins. For SMB, mid-market or self-serve, Leadzy wins.
- Switching cost is low on both sides: CSV + CRM integrations.
Positioning
Cognism is mid-market and enterprise B2B, with particular strength in UK/DACH/Benelux markets. The product includes Cognism Prospector, Chrome extension, Diamond Data (extra-verified phones) and intent signals.
Leadzy is self-serve, cross-geography via live web, and optimised for SMB through mid-market.
Pricing & commercial terms
Cognism does not publish prices. Third-party reports (Vendr, G2 reviews, public RFPs) place entry near $15,000–$25,000/year for a small team, with annual-only billing. Platinum/Diamond add-ons for premium mobile numbers increase cost.
Leadzy is $49/mo Starter, $149/mo Growth (5 users), custom Scale. Monthly or annual. Cancel in-app.
- Cognism: not public, ~$15k+/yr, annual-only
- Leadzy: public, $49/mo entry, monthly or annual
- Pilot cost differs by an order of magnitude
Data depth & compliance
Cognism's Diamond Data (their verified mobile number layer) is widely regarded as the best in the EU market, with GDPR-compliant sourcing and documented lawful basis. For teams where mobile phone outreach is core, this is a genuine advantage.
Leadzy's mobile coverage via premium enrichment is solid but does not match Cognism Diamond Data on EU. For email-led outreach, Leadzy is competitive.
Intent & signals
Cognism ships intent data via Bombora integration plus sales triggers (funding, hiring, tech-adoption). Solid for enterprise ABM.
Leadzy includes 62 composable detectors on every paid plan — broader at entry pricing than Cognism's included intent.
Implementation
Cognism implementations typically run 2–6 weeks with a CSM. Salesforce bi-directional sync, team onboarding, intent configuration.
Leadzy is same-day self-serve. 1–3 days for 5–20 seat rollouts.
Verdict
See the Who-should-switch block and scenarios below for archetype guidance. Short version: Cognism for EU-focused ABM with phone outreach; Leadzy for transparent, signal-led self-serve.
"Cognism's Diamond Data is legitimately best-in-class for EU mobile numbers. If that is your motion, it is worth the contract."

Real cost by team size

Leadzy — Pros
- Public pricing, monthly billing, cancel anytime
- 62 intent detectors included on every plan
- Live-web freshness and strong SMB coverage
- Self-serve — no procurement required
Leadzy — Cons

Who should switch, who should stay
Stay on (or choose) Cognism if your motion is EU/UK mid-market or enterprise ABM with heavy phone-outreach components, if Diamond Data is a specific requirement, or if your budget supports $15k+/yr annual commitment. Choose Leadzy if pricing transparency and monthly flexibility matter, if your budget is under $10k/yr, if you sell SMB or mid-market, or if signal-led self-serve fits your motion. Many teams use Leadzy as a 6–12 month bridge while evaluating whether Cognism's deeper EU contract makes sense.
Real-world scenarios
UK SaaS scaling outbound to DACH
Problem: A UK startup expanding into German mid-market needs verified German mobile numbers and GDPR-compliant sourcing.
Cognism: Cognism Diamond Data is the industry standard for this motion.
Leadzy: Leadzy covers EU via live-web but does not match Diamond Data depth for phone numbers specifically.
Verdict: Cognism is the better fit if phone outreach is core.
US startup piloting before a data contract
Problem: A seed-stage US startup needs to validate outbound fit before signing any annual contract.
Cognism: Cognism is demo-to-quote-to-contract; no realistic pilot path.
Leadzy: Leadzy self-serve 7-day trial covers this motion cleanly.
Verdict: Leadzy is the only realistic pilot choice.
Mid-market RevOps consolidating stack
Problem: A 40-person SaaS is auditing $80k/yr of data spend across Cognism, ZoomInfo and point tools.
Cognism: Cognism renewal focuses on multi-year discounts and bundles.
Leadzy: Leadzy monthly contract makes 90-day parallel pilot low-risk.
Verdict: Leadzy's contract structure makes audit-and-rebuild easier.
SMB agency targeting local UK businesses
Problem: A London agency targets local service businesses — plumbers, accountants, clinics.
Cognism: Cognism's SMB / local coverage is thinner than specialist tools.
Leadzy: Leadzy sources directly from Google Maps with verified local phone + reviews.
Verdict: Leadzy is the clear fit for UK SMB.
Enterprise ABM into 200 target accounts
Problem: A 25-seat ABM team needs deep EU contact + org-chart data for 200 named accounts.
Cognism: Cognism's depth and Diamond Data align with the motion.
Leadzy: Leadzy contributes triggers but does not match enterprise contact depth at this scale.
Verdict: Cognism anchors; Leadzy can layer live triggers on top.
