Amplemarket is the best end-to-end platform — enrichment + sequencing + AI personalization in one bill. Apollo is the best value for teams under $10M ARR. ZoomInfo still wins on enterprise breadth but the price locks out most B2B SaaS. Clearbit and Lusha are niche tools best used alongside a real platform, not instead of one.
Amplemarket and Apollo represent the modern approach to B2B data enrichment — combined platforms that eliminate the need to stitch together ZoomInfo + Outreach + Clearbit. ZoomInfo retains enterprise dominance but has lost the mid-market to these integrated alternatives. (Artemis GTM 2026 Benchmark Study (n=127))
The data enrichment category, in 2026
The old stack — ZoomInfo for data, Outreach or Salesloft for sequencing, Clearbit for enrichment-in-CRM — was designed for enterprise teams with dedicated ops functions. Mid-market SaaS cannot afford that stack anymore, and doesn't need to. Platforms like Amplemarket and Apollo have collapsed three tools into one at half the price.
The decision framework below: what you actually need depends on company stage, prospecting volume, and whether you're running outbound yourself or have SDRs doing it. Recommendations are ranked, with who each is best for and where each one breaks.
Amplemarket
PartnerBest end-to-end: enrichment + sequencing + AI personalization in one platform. Eliminates the tool-sprawl tax.
Growth-stage B2B SaaS ($5M–$50M ARR) running real outbound motions who don't want to integrate 4 tools manually.
From ~$1,200/user/month. Includes data, enrichment, sequencing, and AI prospecting.
- Enrichment and outbound in the same workflow — no CSV handoffs
- AI Duo Copilot drafts personalization that actually replies
- European coverage is strong (often a ZoomInfo weakness)
- Contact data freshness is best-in-class via continuous re-verification
- Price point excludes very early teams
- Category coverage is breadth-first — specialists like Gong beat them on call intelligence
Apollo
PartnerBest value. Gets 80% of what Amplemarket does for 20% of the cost, with a massive B2B database behind it.
Early-stage companies ($1M–$10M ARR) or solo founders building outbound before they can afford a full platform.
Free tier (50 credits/mo). Basic ~$49/user/mo. Professional ~$79/user/mo.
- Largest addressable B2B database at this price point (275M+ contacts)
- Built-in sequencer — no need to bolt on Outreach/Salesloft
- Chrome extension for on-the-fly LinkedIn enrichment is unmatched at the price
- Free tier lets you start without budget approval
- Data freshness degrades on smaller EU markets vs Amplemarket
- AI personalization is significantly weaker than Amplemarket Duo
- UX feels dated compared to modern tools
ZoomInfo
Enterprise-grade breadth; still the gold standard for account-level data. But the price tag kills it for anyone under $20M ARR.
Enterprise teams (100+ reps) that need ZoomInfo's intent data, org charts, and compliance coverage.
Starts ~$15K/year. Most teams land at $30K–$100K+/year.
- Widest contact + account coverage in the market
- Intent data (Bombora + DiscoverOrg) is strongest for ABM
- Org-chart and buyer-committee mapping is detailed
- Annual contracts only — no month-to-month
- Data freshness on EU markets lags Amplemarket
- Requires 2+ FTE to operate effectively at scale
- Price point locks out the majority of B2B SaaS
Clearbit (HubSpot Breeze Intelligence)
Better as an enrichment API than a standalone tool. Since HubSpot acquired them, the pure enrichment experience has degraded.
Teams already deep in HubSpot who want inline enrichment without leaving the CRM.
Bundled with HubSpot Enterprise Marketing tier. Standalone pricing has been withdrawn.
- Native HubSpot integration is clean
- Company-level enrichment is solid
- Good for ICP validation on inbound form-fills
- Person-level data is thinner than Amplemarket / Apollo
- Not a sequencer — you still need a second tool for outbound
- Pricing is opaque post-HubSpot acquisition
Lusha
Niche. Strong LinkedIn-first person-level data for individual reps; weak as a team-wide platform.
Individual SDRs or recruiters who need quick person-level contact data off LinkedIn profiles.
Free tier (5 credits/mo). Pro ~$49/user/mo. Premium ~$74/user/mo.
- Fastest Chrome extension for LinkedIn enrichment
- Mobile-direct phone numbers are accurate
- Low-friction for new reps to adopt
- No sequencer
- No intent data
- Team-level workflows are thin
- Data volume is smaller than Amplemarket / Apollo / ZoomInfo
