Your HubSpot CRM is only as good as the data inside it. And if you've been relying on HubSpot Insights (now deprecated as of March 2025), you already know the gap. Third-party enrichment tools have stepped in — but which ones actually deliver for HubSpot teams?

We tested and compared the top data enrichment tools that integrate with HubSpot in 2026. No vendor fluff — just honest analysis of what works, what doesn't, and what it actually costs.

Why HubSpot Teams Need Third-Party Enrichment

HubSpot's native enrichment (now Breeze Intelligence, formerly Clearbit) covers basic company data. But most B2B teams need more: verified emails, direct phone numbers, technographics, job change tracking, and real-time updates.

The problem? Most enrichment tools charge per credit, and costs spiral fast when you're enriching thousands of contacts monthly. Here's how the major players stack up.

Tool-by-Tool Comparison

1. Breeze Intelligence (HubSpot Native)

Best for: Teams already on HubSpot Professional+ who need basic company enrichment.

• Pricing: $45/month for 100 credits ($0.45/credit). 1,000 credits ~$450/month. Credits expire monthly — no rollover.
• Strengths: Native HubSpot integration, no setup, company data is solid
• Limitations: No phone number enrichment, no LinkedIn scraping, requires HubSpot Pro ($800/month) for most features, no job change tracking
• Real cost for 1,000 contacts/month: ~$450 + $800 HubSpot Pro = $1,250/month

2. ZoomInfo

Best for: Enterprise teams with big budgets who need the largest B2B database.

• Pricing: Starts ~$15,000/year (annual contracts only, opaque pricing)
• Strengths: Massive database, intent data, org charts, technographics
• Limitations: Expensive, requires annual commitment, data accuracy varies by region (weaker outside North America), complex HubSpot sync can create duplicates
• Real cost: $1,250-2,500+/month depending on tier

3. Apollo.io

Best for: SMBs who want enrichment + outbound in one platform.

• Pricing: Free tier (limited), paid plans from $49/month per user
• Strengths: Large email database, built-in sequencing, affordable entry point
• Limitations: Phone number accuracy is inconsistent, HubSpot integration can be buggy, enrichment depth is limited compared to ZoomInfo, data freshness varies
• Real cost: $49-119/month per user + time spent on data cleanup

4. Cognism

Best for: European teams needing GDPR-compliant phone-verified data.

• Pricing: Custom pricing, typically $15,000-30,000/year
• Strengths: Diamond Data (phone-verified mobiles), strong European coverage, GDPR-compliant
• Limitations: Expensive, weaker on technographics, HubSpot integration requires some setup, no job change tracking
• Real cost: $1,250-2,500/month

5. KeepSync

Best for: HubSpot teams who need ongoing contact monitoring and job change alerts.

• Pricing: Starter plan $79/month for 1,000 contacts. Predictable pricing, no per-credit fees.
• Strengths: Continuous monitoring (weekly scans across 30+ sources), 94% accuracy on job changes, native HubSpot integration, automatic CRM updates
• Limitations: Focused on contact monitoring and job changes — not a full-database enrichment tool for net-new prospecting. Smaller total database than ZoomInfo or Apollo.
• Real cost: $79/month for 1,000 contacts

Pricing Comparison at Scale

Here's what enrichment actually costs at 1,000 contacts per month:

• Breeze Intelligence: ~$1,250/month (credits + HubSpot Pro requirement)
• ZoomInfo: ~$1,250-2,500/month (annual contract)
• Apollo: $49-119/month per user (but limited enrichment depth)
• Cognism: ~$1,250-2,500/month (annual contract)
• KeepSync: $79/month (flat rate, continuous monitoring)

The difference is the model: credit-based tools penalize growth. The more contacts you enrich, the more you pay — often unpredictably. Flat-rate tools like KeepSync let you scale without cost surprises.

How to Choose the Right Tool

Choose Breeze Intelligence if you're already on HubSpot Pro and only need basic company data enrichment for a small number of records.

Choose ZoomInfo or Cognism if you need a comprehensive B2B database for net-new prospecting and have the budget for $15,000+/year.

Choose Apollo if you're an SMB that wants enrichment bundled with outbound sequencing at a lower price point.

Choose KeepSync if your priority is keeping existing CRM data fresh, tracking job changes, and getting alerts when key contacts move — without per-credit pricing.

The Bottom Line

There's no single "best" enrichment tool — it depends on whether you're enriching net-new prospects or maintaining existing data quality. Most mature teams use a combination: one tool for prospecting data, another for ongoing CRM hygiene.
