Why People Are Leaving ZoomInfo

ZoomInfo is the enterprise standard for B2B sales intelligence, but its $15,000-25,000+ annual contracts and complex pricing have pushed many small and mid-size teams to explore alternatives that deliver similar data accuracy at a fraction of the cost.

#1

ZoomInfo contracts start at $15,000-25,000+ annually — prohibitive for teams under 20 SDRs

#2

Many sales intelligence tools pad databases with HQ switchboard numbers that never connect to decision-makers

#3

Credit systems are often confusing — phone reveals can cost 5-10x email reveals, burning budgets fast

#4

Data accuracy claims rarely match reality — independent tests show 30-40% variance between platforms

#5

Full CRM integration often locked behind enterprise tiers, forcing manual data entry on lower plans

3 Best ZoomInfo Alternatives — Detailed Reviews

⭐ Our Top Pick
4.6

1. Lusha

Free - $299.95/mo

Best for: Teams that prioritize data accuracy and compliance over raw database size

Lusha's crowdsource-verified database delivers 80-90% accuracy on direct dials — no HQ switchboard numbers. With 1.3M users validating data quality, website visitor identification included on all plans, and the fastest onboarding in the category (5 minutes to first prospect), Lusha gives you fewer but better contacts that actually convert. GDPR, CCPA, ISO 27701, and SOC II Type 2 certified for teams in regulated industries.

Key Advantage: Crowdsourced data verification by 1.3M users delivers 80-90% accuracy on direct dials — independently confirmed in blind head-to-head tests against competitors

Pros

80-90% data accuracy rate — verified by 1.3M crowdsourced users, consistently beats competitors in head-to-head tests

Direct dials and mobile numbers only — no HQ switchboard numbers padding the database

5-minute onboarding — sign up to selling in under 5 minutes, CRM integration in under 120 seconds

GDPR, CCPA, ISO 27701, and SOC II Type 2 compliant — best-in-class data privacy for regulated industries

Cons

Credit system charges 10 credits per phone reveal vs 1 credit per email — phone-heavy teams burn credits fast

Full CRM bidirectional sync requires Scale (enterprise) plan — lower tiers get basic integration only

Annual credits are front-loaded and don't roll over — use them or lose them

Smaller database than some competitors (focused on quality over quantity)

4.5

2. Apollo.io

Free - $119/user/mo

Best for: High-volume outbound teams needing maximum database coverage with built-in engagement

Apollo.io's 210M+ contact database is the largest in the mid-market category, with AI-written personalized emails, a built-in dialer with call recording, and multi-channel sequences combining email, phone, and LinkedIn in one workflow. Predictive lead scoring ranks prospects by conversion likelihood. The free plan includes 1,200 credits/year for smaller teams.

Key Advantage: 210M+ contact database with built-in multi-channel engagement (email, phone, LinkedIn) and AI-written personalized outreach — all in one platform

Pros

Massive contact database (210M+) with accurate company and intent data for prospecting

AI-written personalized emails dramatically reduce time spent on outreach

Built-in dialer with call recording and AI insights eliminates need for separate tools

CRM integrations with Salesforce and HubSpot keep data synced automatically

Cons

Credit system can be confusing — different actions consume different credit amounts

Email accuracy hovers around 65-70% in practice, leading to some bounce rates

LinkedIn actions are task reminders, not full automation — still requires manual effort

Credits don't roll over and overage charges ($0.20/credit) can add up quickly

4.5

3. Close CRM

From $29/user/mo

Best for: Sales teams wanting built-in calling, email, and AI follow-up in one CRM — no separate tools needed

Close CRM flips the model — instead of buying a separate sales intelligence tool, Close builds calling, email sequences, SMS, and Chloe AI (autonomous voice agent that calls and qualifies leads 24/7) directly into the CRM. No integrations, no data syncing, no separate subscriptions. Chloe has made 1M+ calls during beta and books meetings automatically.

Key Advantage: Chloe AI voice agent calls inbound leads automatically within seconds, qualifies them, answers objections, and books meetings 24/7 — no human intervention required

Pros

All-in-one sales platform: calling, email, SMS, and CRM in one tool

AI agent Chloe automates outbound calling and lead qualification

Power Dialer eliminates manual dialing for high-volume teams

14-day free trial with no credit card required

Cons

Solo plan limited to 1 user and 10,000 leads

Advanced automation only available on Growth plan and above

Calling costs are usage-based beyond included minutes

Less suited for inbound-focused or relationship-based sales

Our Verdict

For data accuracy and compliance, Lusha is the clear winner — 80-90% verified accuracy means fewer wasted credits, higher connect rates, and faster pipeline build. Start with the free plan (40 credits/month) to test accuracy in your market. For high-volume outbound across broad markets, Apollo.io delivers the largest database with built-in engagement tools — ideal for teams that need to prospect AND engage from one platform. For teams that want to eliminate the sales intelligence + CRM + dialer stack entirely, Close CRM with Chloe AI is the most integrated option — one subscription, one interface, AI that calls your leads for you. Our recommendation: start with Lusha's free plan to validate accuracy, then decide whether you need Apollo's volume or Close's all-in-one approach.
