Best Sales Intelligence Tools
Finding the right sales intelligence platform is the difference between your SDRs booking 14 meetings a month or wasting credits on bad phone numbers and bouncing emails. We tested the top platforms head-to-head on the metrics that actually matter: data accuracy, connect rates, credit value, and time-to-first-meeting. Here are the three that deliver the best ROI for B2B sales teams in 2026.
TL;DR — Quick Answer
Our #1 pick: Lusha — Teams that prioritize data accuracy and compliance over raw database size. (Free - $299.95/mo). Also worth considering: Apollo.io and Close CRM.

Lusha
Teams that prioritize data accuracy and compliance over raw database size
Free - $299.95/mo
Crowdsourced data verification by 1.3M users delivers 80-90% accuracy on direct dials — independently confirmed in blind head-to-head tests against competitors
Quick Summary
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.
ZoomInfo contracts start at $15,000-25,000+ annually — prohibitive for teams under 20 SDRs
Many sales intelligence tools pad databases with HQ switchboard numbers that never connect to decision-makers
Credit systems are often confusing — phone reveals can cost 5-10x email reveals, burning budgets fast
Data accuracy claims rarely match reality — independent tests show 30-40% variance between platforms
Full CRM integration often locked behind enterprise tiers, forcing manual data entry on lower plans
Quick Comparison
3 Best ZoomInfo Alternatives — Detailed Reviews
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)
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
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
