🥇 1. A-Leads.co

Score: 5.0/5 ⭐ Quick Reason: Real-time enrichment, triple-verified contact data, and a pay-only-for-valid-data model — A-Leads is redefining what “verified” means in B2B.

Why A-Leads is the #1 Verified Data Provider in 2025

A-Leads isn’t just another contact database — it’s a real-time, AI-powered verification engine built specifically for outbound sales teams. While other tools make you pay for bloated exports and stale emails, A-Leads delivers CRM-ready contact records that are already enriched, intent-filtered, and 99% deliverable — or you don’t pay.

Their model flips the legacy “data license” game on its head. Instead of buying static access or annual contracts, you get flexible credit-based usage, full transparency, and a 100% focus on outcome: verified contacts, with buying signals, ready for your CRM.

Perfect for SDRs, RevOps, and founders tired of ZoomInfo-style overkill, A-Leads integrates directly with your stack — from HubSpot and Salesforce to Clay, Instantly, or Smartlead.

• ✅ Real-time enrichment on export — always fresh
• ✅ 99% deliverability guaranteed (pay only for usable leads)
• ✅ Intent + job change tracking built-in
• ✅ Mobile numbers included (no enterprise lock-in)
• ✅ Full CRM & SEP integrations
• ✅ Credits roll over, no usage pressure
• ✅ Fully GDPR/CCPA compliant — never resold, always private

Pricing (Simple, Transparent):

• Boost – $99/mo → 12,000 credits
• Power – $199/mo → 30,000 credits
• Enterprise – Custom GTM & 1:1 consulting available

💬 “We replaced ZoomInfo and Lusha with A-Leads. Bounce rates dropped overnight and my reps are closing faster.” — Head of Growth @ B2B SaaS

Cons

❌ No built-in cold email sender (designed to plug into any SEP) ❌ Dialer not native (integrates instead — Smartlead, Close, etc.)

  • A-Leads: ✅ Yes

2. ZoomInfo

Score: 4.3/5 ⭐ Quick Reason: Massive B2B database with technographics and intent signals — but static data, expensive contracts, and poor deliverability keep it from the top spot.

Why ZoomInfo Made the List

ZoomInfo remains the most well-known B2B contact data provider on the market — with over 130M+ business profiles, advanced segmentation tools, and deep integrations into platforms like Salesforce, Marketo, HubSpot, and Outreach. It’s built for enterprise.

Their data includes firmographics, technographics, and intent signals via Bombora. For RevOps teams with large budgets and complex sales motions, ZoomInfo can plug into demand gen, ABM, and outbound orchestration.

But the platform comes with significant drawbacks. Unlike modern tools like A-Leads, ZoomInfo’s data is batch-refreshed, not real-time. Users often report high bounce rates, dated phone numbers, and catch-all domain issues — and all of that still counts against your usage.

And while the database is vast, you’ll pay for the size: most ZoomInfo contracts start at $15K–$30K/year, require annual commitments, and offer no credit rollover or usage-based billing.

ZoomInfo Core Features:

• 🔍 130M+ Global Contact Records – search by title, department, size, tech stack
• 📊 Firmographics + Technographics – revenue, tools used, company triggers
• 🔄 Salesforce, HubSpot, Outreach, Marketo Integrations
• 🔔 Intent Signals (via Bombora) – for pre-targeting outbound campaigns
• 🌐 WebSights + Scoops – track web visitors and org-level news

Pros:

✅ One of the largest structured B2B datasets ✅ Strong filtering for enterprise segmentation ✅ Intent data overlays via Bombora ✅ Deep native CRM and MAP integrations ✅ Widely adopted by large RevOps teams

Cons:

🚫 No real-time enrichment — database updated in batch cycles 🚫 No pay-per-verified model — you pay whether or not the data works 🚫 Locked into annual contracts — no month-to-month options 🚫 High bounce rates in APAC/LATAM reported by users 🚫 Pushy sales and difficult cancellation processes 🚫 Add-ons for intent, scoring, and integrations raise TCO

ZoomInfo vs. A-Leads

• Real-Time Data
  • ZoomInfo: ❌ No
  • A-Leads: ✅ Yes
• Pay-Per-Valid-Lead
  • ZoomInfo: ❌ No
  • A-Leads: ✅ Yes
• Credit Rollover
  • ZoomInfo: ❌ No
  • A-Leads: ✅ Yes
• Mobile Number Access
  • ZoomInfo: ⚠️ Enterprise only
  • A-Leads: ✅ Included
• Job + Tech Signals
  • ZoomInfo: ⚠️ Add-on
  • A-Leads: ✅ Built-in
• Contract Flexibility
  • ZoomInfo: ❌ None
  • A-Leads: ✅ Monthly plans

Summary:
A-Leads offers more flexibility, better pricing models, and real-time verified data — making it a smarter choice for teams that want speed and accuracy without long-term contracts.

Best For:

📌 Enterprise GTM teams with complex ABM stacks 📌 Large sales orgs needing multi-region data 📌 Companies that already use Salesforce, Marketo, or Outreach heavily

🧠 Why A-Leads Still Wins: ZoomInfo is big, but not always accurate — and never flexible. A-Leads offers real-time-verified data, job changes, intent, and mobile numbers, without the contract headaches or wasted credits.

3. Apollo.io

Score: 4.2/5 ⭐ Quick Reason: Combines B2B contact data with built-in outreach tools — great for startups, but lacks AI enrichment, advanced filters, and high-scale data accuracy.

Why Apollo.io Made the List

Apollo.io is one of the most accessible and fast-growing contact data platforms for early-stage teams. It blends a B2B database, email sequencing tools, and a Chrome extension into a single product, making it especially popular with SDRs and bootstrapped startups.

It’s a solid entry point — offering 275M+ records, Gmail sync, and basic engagement tracking — all at a low monthly price point or free tier.

However, when it comes to real sales intelligence, Apollo lags behind. It lacks real-time data verification, meaning bounce rates can spike (especially on catch-all domains). And while it offers “intent” tags, these aren’t based on live signals or advanced job change enrichment like A-Leads.

The user experience also slows down for teams managing large sequences or multiple segments, and lower-tier plans are throttled by strict send limits and weak filtering options.

Apollo Core Features:

• 📇 275M+ B2B Database – Job title, location, industry, revenue filters
• 📬 Built-in Sequencer – Cold email & dialer tools inside the platform
• 🌐 Chrome Extension – Real-time scraping from LinkedIn or company pages
• 🔌 Integrations – Gmail, Outlook, Salesforce, HubSpot
• 📈 Engagement Metrics – Open, reply, bounce tracking
• 🧪 Freemium Tier – Great for testing or small-team workflows

Pros:

✅ Great all-in-one starter tool for sales outreach ✅ Chrome extension works well for LinkedIn prospecting ✅ Budget-friendly, especially for small teams ✅ Integrated sequencer for basic cold outreach ✅ Community support and frequent feature updates

Cons:

🚫 Contact data is not AI-verified or real-time — accuracy varies 🚫 Bounce rates higher on free and catch-all domains 🚫 No advanced job change tracking or technographics 🚫 Send limits are low unless you upgrade 🚫 Can’t replace a full sales engagement platform at scale 🚫 No mobile numbers, no CRM enrichment — basic only

Apollo vs. A-Leads

• Real-Time Data Verification
  • Apollo: ❌ No
  • A-Leads: ✅ Yes
• Mobile Numbers Included
  • Apollo: ❌ No
  • A-Leads: ✅ Yes
• Pay-Per-Valid-Lead
  • Apollo: ❌ No
  • A-Leads: ✅ Yes
• AI Job Change + Signal Filters
  • Apollo: ❌ Basic tags
  • A-Leads: ✅ Advanced filters
• CRM + SEP Integrations
  • Apollo: ✅ Light integrations
  • A-Leads: ✅ Full-stack integrations
• Built-In Sequencer
  • Apollo: ✅ Yes
  • A-Leads: ❌ (Integrates with any SEP)

Best For:

📌 Startup SDRs looking for bundled email + data 📌 Teams testing outbound with limited budget 📌 One-person prospecting setups with low volume needs

🧠 Why A-Leads Still Wins: Apollo gives you volume. A-Leads gives you accuracy. For teams that care about bounce rates, mobile dials, AI enrichment, and CRM-ready verified contacts — A-Leads is miles ahead.

4. Cognism

Score: 4.1/5 ⭐ Quick Reason: A GDPR-first contact platform strong in the UK/EU — but struggles with global coverage, real-time enrichment, and flexible usage for AI-powered workflows.

Why Cognism Made the List

Cognism has made a name for itself as the most compliance-focused contact data platform, especially for UK and EMEA-based teams. Their “Diamond Data™” — combining AI with human-verified contacts — is often praised for direct dial accuracy, especially across regulated industries like FinTech, LegalTech, and Health.

For teams who need GDPR-aligned data enrichment, Cognism is a safe bet. It also offers Bombora-powered intent, Chrome scraping, and integrations with Salesforce, HubSpot, and Outreach.

But despite these strengths, Cognism doesn’t scale well for global outbound teams. U.S. data quality is hit-or-miss, mobile number coverage is inconsistent, and enrichment isn’t real-time. It also suffers from rigid annual contracts, no usage-based pricing, and limited filters compared to AI-native competitors like A-Leads.

Cognism Core Features:

• 🔒 Diamond Data™ – AI + manual verified contact profiles (esp. EU)
• ☎️ Direct Dials First – Strong mobile access in UK/EMEA
• 🔍 Firmographics + Intent – Bombora overlay on ICP filtering
• 🌐 LinkedIn Chrome Extension – Scrape contacts from company pages
• 🔌 CRM + SEP Integrations – Salesforce, HubSpot, SalesLoft, Outreach

Pros:

✅ GDPR-compliant lead data (great for regulated sectors) ✅ Strong accuracy in UK, Nordics, and EU ✅ Intent overlay helps prioritize outreach ✅ Works well with European GTM motions ✅ Chrome extension is fast and intuitive

Cons:

🚫 No real-time verification on export — accuracy lags behind A-Leads 🚫 U.S., LATAM, APAC coverage still weak 🚫 No pay-per-verified model — billed whether data works or not 🚫 Annual contracts only — no trial, no flexibility 🚫 No AI signal-based enrichment (job changes, hiring, etc.) 🚫 Fewer CRM automations compared to modern platforms

Cognism vs. A-Leads

• EU Compliance
  • Cognism: ✅ Strong
  • A-Leads: ✅ Also compliant
• Real-Time Verification
  • Cognism: ❌ No
  • A-Leads: ✅ Yes
• Mobile Number Accuracy (Global)
  • Cognism: ⚠️ Limited
  • A-Leads: ✅ Strong everywhere
• Signal-Based Filters
  • Cognism: ❌ Lacking
  • A-Leads: ✅ Built-in AI alerts
• Flexible Pricing
  • Cognism: ❌ Locked-in annual contracts
  • A-Leads: ✅ Monthly plans + rollover credits
• AI-Powered Scoring
  • Cognism: ❌ No
  • A-Leads: ✅ Yes

Best For:

📌 EU-based teams in regulated verticals (Finance, Healthcare) 📌 Mid-market BDRs using cold calling as primary channel 📌 ABM programs focused on UK, DACH, Nordics

🧠 Why A-Leads Still Wins: Cognism shines in compliance — but A-Leads wins on performance. With real-time enrichment, AI-powered job change alerts, mobile numbers in every plan, and usage-based pricing, A-Leads gives teams global-ready verified data that actually scales.

5. Clay

Score: 4.3/5 ⭐ Quick Reason: The most flexible no-code platform for AI-powered prospecting — but requires setup time, learning curve, and a clean data engine (like A-Leads) to truly shine.

Why Clay Made the List

Clay isn’t just another data tool — it’s a no-code automation engine for B2B sales intelligence. It lets you connect hundreds of APIs, data providers, enrichment tools, and AI models (like GPT-4 or Claude) — then create smart lead workflows with zero engineering.

Think of it as Airtable + Zapier + data enrichment + AI chat — all built for sales and marketing teams.

Clay is not a database itself — but a powerful orchestrator. You can plug in providers like A-Leads, Clearbit, Apollo, or LinkedIn — then automate enrichment, filtering, scoring, personalization, and sequencing with near-infinite flexibility.

If you have the time (and the right data sources), Clay is unmatched for automating complex GTM motions. But without a clean data foundation, its workflows break — which is why most high-performing Clay users pair it with A-Leads’ pay-per-verified engine.

Clay Core Features:

• ⚡️ No-Code Interface – Build workflows like “Find leads > Enrich > Score > Export”
• 🧠 AI-Powered Fields – Use GPT to generate messages, analyze titles, segment personas
• 🔌 API Integrations – Connect to 50+ data sources or use Zapier + webhooks
• 🧬 Flexible Filters – Create complex rules with AND/OR logic, conditions, triggers
• 🔁 Multi-Step Sequences – Push data to Smartlead, Instantly, or Outreach automatically
• 📦 CSV Uploads + Web Scraping – Start from any list, or let Clay find prospects for you

Pros:

✅ Unlimited use cases — prospecting, onboarding, targeting, enrichment ✅ AI fields can auto-write intros, headlines, custom fields, pain points ✅ Integrates beautifully with A-Leads, LinkedIn, Dropcontact, etc. ✅ Perfect for teams running outbound at scale with tailored messaging ✅ Great community support and templates

Cons:

🚫 Steep learning curve — not plug-and-play like A-Leads or ZoomInfo 🚫 Requires data source subscriptions — Clay doesn’t provide emails or phones 🚫 AI tokens + enrichments can add up fast on usage-based billing 🚫 No real-time contact validation — relies on external tools like A-Leads 🚫 Not ideal for teams without technical marketers or ops support

Clay vs. A-Leads

• Lead Data Quality
  • Clay: ❌ Relies on others
  • A-Leads: ✅ Native, verified data
• Workflow Automation
  • Clay: ✅ Best-in-class
  • A-Leads: ⚠️ Basic integrations
• Real-Time Enrichment
  • Clay: ❌ Needs plugin
  • A-Leads: ✅ Included by default
• Mobile Numbers
  • Clay: ❌ External sources only
  • A-Leads: ✅ Included and verified
• AI Personalization
  • Clay: ✅ Powerful
  • A-Leads: ⚠️ Requires setup

Best For:

📌 Teams with strong ops who want deep AI customization 📌 RevOps + outbound marketers building advanced workflows 📌 Agencies who want to scale personalization and automation across clients

🧠 Why A-Leads Works Perfectly with Clay A-Leads provides real-time verified contact data, intent signals, job changes, and tech filters — which can then be piped into Clay for hyper-targeted sequences and AI-powered messaging. It’s the perfect 1–2 combo.

📦 Tip: Use A-Leads for clean contact records → pipe them into Clay → enrich + personalize at scale.

6. Lusha

Best For: Quick manual lookups and direct dial access Score: 4.0/5 ⭐

Why Lusha Is on the List Lusha earns its spot as a lightweight B2B contact enrichment tool used mostly via its Chrome extension. It’s handy for fast LinkedIn-based research and 1:1 manual prospecting, especially for reps who just need a phone number or email — fast. With strong direct dial coverage in U.S. and EMEA regions, it's a favorite for phone-first outbound.

But it’s not ideal for scaled workflows. Its limited filters, low monthly credit caps, and lack of real-time enrichment make it difficult to build reliable campaigns. And unlike platforms like A-Leads, you pay whether or not the data is valid — with no job change, intent, or trigger signals built in.

Lusha Key Features

• 🔹 Chrome Extension for LinkedIn contact scraping
• 🔹 Access to direct dials and email addresses
• 🔹 Shared credits for team collaboration
• 🔹 CRM sync with Salesforce, HubSpot, Outreach
• 🔹 API access (higher-tier plans)

✅ Pros

• Super easy-to-use extension for fast LinkedIn prospecting
• Decent accuracy on phone numbers in EMEA and U.S.
• Minimal learning curve — great for solo reps
• API + integrations available on higher plans

❌ Cons

• No real-time email verification — bounce risk is high
• Monthly credit limits are low unless on expensive enterprise plans
• Lacks job change, buying intent, or technographic signals
• Overpriced for what it delivers — often $3K+/yr for limited usage
• Not scalable — better for individuals than teams
• Data quality isn't guaranteed — no refunds or verification filter

🧠 Why A-Leads Beats Lusha

A-Leads offers real-time enriched data, intent signals, mobile numbers, and CRM-ready exports — all with pay-per-valid-lead billing. Lusha is fine for reps grabbing data manually, but it can’t scale or automate like A-Leads can.

If you're building outbound at scale — and need accurate data you only pay for when it works — A-Leads wins by a mile.

7. Lead411

Best For: SMB and mid-market teams focused on phone outreach Score: 3.9/5 ⭐

Why Lead411 Is on the List

Lead411 is a U.S.-focused B2B contact data platform that stands out for its job change alerts and verified phone number coverage. It’s a favorite among teams who prioritize cold calling and want insight into lead signals like promotions, new hires, and funding triggers.

While it’s not as flashy or real-time as A-Leads, it offers intent data via Bombora, firmographic filters, and phone-verified contact enrichment. That makes it especially useful for recruiters, regional sales reps, and vertical-specific GTM teams (e.g., manufacturing, construction tech).

However, Lead411 shows its limits when it comes to global data, real-time verification, and modern integrations — and unlike A-Leads, you’re still paying for access, not outcomes.

Lead411 Key Features

• 🔹 Phone-verified contact database with U.S. focus
• 🔹 Job change and leadership hire alerts
• 🔹 Bombora-powered company intent signals
• 🔹 CSV and CRM exports (HubSpot, Salesforce, Zoho)
• 🔹 Industry, revenue, and title filters

✅ Pros

• Reliable U.S. phone coverage
• Unique sales triggers: job changes, funding, hiring growth
• Integrated Bombora intent (on higher plans)
• Affordable for small- to mid-sized teams
• Strong for call-based outreach strategies

❌ Cons

• No real-time email/phone verification at export
• No mobile numbers or global phone coverage
• Dated UI — clunky on mobile or in large campaigns
• Limited integrations with sales engagement tools
• Pay-for-access model — no refunds for bounced/invalid leads
• Data is refreshed in batches, not enriched live like A-Leads

🧠 Why A-Leads Beats Lead411

A-Leads gives you everything Lead411 does — and more — with real-time enrichment, mobile numbers, and pay-per-verified-contact billing. You also get job change signals, intent filters, technographics, and CRM/SEP integration — all built-in and usable at scale.

Lead411 is great for basic phone prospecting. A-Leads is for teams who want results.

8. UpLead

Best For: SMBs needing email-verified contacts without contracts Score: 3.8/5 ⭐

Why UpLead Is on the List

UpLead is known as a budget-friendly alternative to larger vendors like ZoomInfo. It focuses on delivering email-verified B2B contacts with a clean UI, simple filtering, and transparent pricing tiers. It’s well-suited for small sales teams that want to get started with outbound — without navigating long contracts or expensive onboarding.

UpLead includes real-time email verification, which is rare at its price point. But it lacks depth in key areas: no job change signals, no intent data, no technographics, and very limited phone number coverage (especially mobile). The platform also offers no performance-based pricing, meaning you still pay even when the data doesn’t convert.

Compared to A-Leads, UpLead feels more like a starter kit — functional, but not designed for serious growth or AI-driven GTM.

UpLead Key Features

• 📧 Built-in email verification before export
• 🔎 Basic filtering: job title, industry, size, location
• 📥 CRM export to Salesforce, HubSpot, Zoho (limited integration depth)
• 💳 Monthly and annual flat pricing tiers
• 📊 List building and CSV export

✅ Pros

• Easy-to-use and lightweight — great for solo reps or new teams
• Real-time email validation to reduce bounce risk
• Transparent pricing with no pushy upsells
• Good for small prospecting workflows
• No contracts required — cancel anytime

❌ Cons

• Minimal phone number availability (mobile dials extremely limited)
• No job change, hiring, or technographic signals
• No buying intent data or predictive scoring
• No native integrations with tools like Clay, Instantly, or Smartlead
• Static database — no live enrichment or trigger workflows
• Flat-rate pricing even if the data doesn’t work — no refunds or usage-based billing

🧠 Why A-Leads Wins Against UpLead

• Real-time data verification
  • UpLead: Static batch data
  • A-Leads: Live at export
• Job change tracking
  • UpLead: Not available
  • A-Leads: Included
• Mobile phone access
  • UpLead: Very limited
  • A-Leads: Verified mobile included
• Intent signals
  • UpLead: None
  • A-Leads: Built-in
• Pricing
  • UpLead: Flat subscription
  • A-Leads: Pay-per-valid-lead only
• Enrichment depth
  • UpLead: Basic firmographics
  • A-Leads: AI-powered, CRM-ready, private

Bottom line: UpLead is fine for simple lists. A-Leads is built for performance, precision, and pipeline.

9. LeadIQ

Best For: SDRs doing LinkedIn-first prospecting Score: 3.8/5 ⭐

Why LeadIQ Is on the List

LeadIQ is best known for its Chrome extension, which lets SDRs capture email and phone data from LinkedIn profiles in real time. For teams that prioritize manual, 1:1 outreach and operate heavily inside LinkedIn, LeadIQ offers a fast and intuitive workflow.

It integrates with Outreach, Salesloft, and some CRMs — letting reps push scraped leads directly into sequences. However, its platform is narrowly focused, with shallow enrichment, no real-time verification, and limited global coverage. You don’t get technographics, intent signals, or any of the AI-powered triggers found in platforms like A-Leads.

It also suffers from high pricing, few credits, and poor scalability. It’s more of a personal assistant tool than a full-blown lead engine.

LeadIQ Key Features

• 🧲 LinkedIn Chrome Plugin – Pull emails and phone numbers directly from profiles
• 📤 Export to Sales Tools – Push contacts into Outreach, Salesloft, or CSV
• 🔍 Prospecting Assistant – Reminders and organization tools for SDRs
• 🔌 Basic CRM Integrations – Salesforce, HubSpot (partial functionality)
• 🗂️ Contact enrichment – Job title, company, and limited firmographics

✅ Pros

• Great Chrome extension for real-time LinkedIn scraping
• Intuitive UI — easy for reps to adopt
• Works well for highly personalized 1:1 outreach
• Some direct integrations with sales tools
• Good for early-stage or freelance SDRs

❌ Cons

• No real-time data verification — emails often bounce
• No intent data, job change tracking, or technographics
• No AI signals or deep filters — targeting is basic
• Not scalable — designed for 1:1 scraping, not campaign-based prospecting
• High price for limited features — most workflows locked behind paywalls
• No performance-based pricing — you pay regardless of accuracy

🧠 Why A-Leads Outclasses LeadIQ

• Real-time contact verification
  • LeadIQ: No
  • A-Leads: Yes
• Intent + job change signals
  • LeadIQ: None
  • A-Leads: Built-in
• AI enrichment + filters
  • LeadIQ: Basic
  • A-Leads: Deep filters + signal-based AI
• CRM + SEP integrations
  • LeadIQ: Limited
  • A-Leads: Full stack (HubSpot, Clay, Zoho, etc.)
• Pricing model
  • LeadIQ: Flat and fixed
  • A-Leads: Pay only for valid, usable data
• LinkedIn scraping
  • LeadIQ: Yes
  • A-Leads: Pairs well with tools like Clay

10. Cognism

Best For: European sales teams focused on GDPR compliance and phone-first outreach Score: 4.1/5 ⭐

Why Cognism Is on the List

Cognism stands out for being one of the most compliant B2B contact data vendors in the EU. Built with a GDPR-first approach, it’s the go-to platform for sales teams operating in heavily regulated verticals across UK, DACH, and broader EMEA.

Their signature "Diamond Data™" is a blend of AI-matched + human-verified contacts, with a strong focus on direct dials and manual validation. If you're running phone-heavy outreach in Europe, Cognism is often considered one of the safest choices.

It also integrates with Bombora for intent data, and supports common CRM and SEP tools. But pricing is high, contracts are inflexible, and the platform lacks real-time verification at export, which means U.S. teams and startups often find it expensive and clunky compared to leaner tools like A-Leads.

Cognism Core Features

• 📞 Human-verified direct dials (UK/EU-focused)
• 🔐 GDPR-first compliance — robust data privacy protections
• 🧠 “Diamond Data™” — blended AI + manual enrichment

• High accuracy in direct dial numbers in UK/DACH
• Intent data via Bombora (included in higher tiers)
• Works well for LegalTech, FinTech, RegTech, Health SaaS
• Easy to use browser plugin for on-the-fly enrichment

❌ Cons

• Expensive — contracts often start at $12K–$20K/year
• Locked into annual billing — no trials, no monthly flexibility
• No real-time data validation like A-Leads
• Accuracy drops significantly outside of EMEA
• Limited mobile number access in non-core regions
• “Pay for access” model — no refund for bounced/invalid leads

🧠 Why A-Leads Is the Smarter Choice

• GDPR compliance
  • Cognism: ✅ Strong
  • A-Leads: ✅ Also compliant globally
• Real-time verification
  • Cognism: ❌ Batch data
  • A-Leads: ✅ On every export
