FullEnrich Review 2026: Multi-Waterfall Contact Enrichment — Pricing and Hit Rate

FullEnrich is a credit-based B2B contact enrichment platform that cascades through 15+ providers to maximize email and mobile hit rates. Starting at $69/mo with no seat fees, it achieves 70–85% hit rates on US enterprise contacts and 50–60% on APAC/LATAM markets. It is the deepest pure-waterfall enrichment tool in its price tier. Our rating: 4.3/5.

The case for FullEnrich is straightforward: most enrichment tools query one database and stop. If that database does not have your prospect, you get nothing. FullEnrich solves this by running a cascade — if Provider A fails, Provider B runs, then C, then D — until a verified result is found or the waterfall is exhausted. Failed lookups do not consume credits.

The limitation is equally clear: FullEnrich enriches contact data. It does not tell you when a company is ready to buy. No hiring surge detection, no funding alerts, no tech stack change monitoring. If your outbound motion depends on timing your outreach to buying signals — not just having the right contact — FullEnrich is one piece of a larger stack, not the whole answer.

This review covers the waterfall hit rate in practice, the credit pricing math at each plan tier, data coverage by region, how it connects to your stack, and a direct comparison with SyncGTM, Clay, and Apollo for teams evaluating their enrichment options in 2026.

What Is FullEnrich?

FullEnrich is a B2B contact enrichment platform founded in France and built around a single architectural bet: multi-waterfall enrichment beats single-source databases on hit rate, every time. Instead of maintaining a proprietary contact database, FullEnrich acts as an orchestration layer — routing your input records through 15+ external providers in a defined cascade and returning the first verified result found.

The target user is a contact data ops professional, RevOps engineer, or GTM team that needs to enrich large prospect lists at predictable cost without managing provider relationships individually. FullEnrich handles the cascade logic, provider prioritization, and deduplication — you send a name and company domain, you get back an email or mobile number.

The founders chose a credit-only monetization model with no seat fees, which makes it fundamentally different from per-user tools like Lusha or Kaspr. A team of 10 SDRs using FullEnrich pays the same monthly rate as a team of 1 — the cost scales with usage, not headcount. This is a significant structural advantage for mid-sized outbound teams running high-volume enrichment.

FullEnrich Pricing: Credits, Plans, and What You Actually Pay

FullEnrich publishes its pricing — a rare practice in B2B data tools — and uses a straightforward credit model. Each successful enrichment consumes one credit. Failed lookups (records where the waterfall exhausts all providers without finding a result) do not consume credits. This makes the effective cost per contact predictable: you can calculate your expected cost by multiplying your target list size by your expected hit rate.

The real cost math

On the Growth plan at $149/mo (2,000 credits), if your US enterprise list achieves a 75% hit rate, you are effectively enriching 1,500 contacts per month at $0.10 per contact. Apollo's equivalent enrichment costs roughly $0.12–0.18 per record depending on plan, and ZoomInfo charges $0.15–0.30 per enriched record at scale. FullEnrich's credit-only pricing with no seat fees makes it genuinely cheaper for teams with 3+ users running enrichment workloads.

Annual billing reduces all plan prices approximately 20%. There is no free trial on the standard plans, but FullEnrich offers a sample enrichment run on request — submit 20–50 records and see the hit rate before committing.

FullEnrich Hit Rate: What the Waterfall Actually Delivers

Hit rate is the core metric for any enrichment tool — the percentage of input records that return a valid email or phone number. Single- source tools (Apollo, ZoomInfo own database) typically achieve 55–70% on well-defined US enterprise ICP lists. The multi-waterfall architecture is specifically designed to push this ceiling higher.

FullEnrich's reported hit rates by region, based on user data and independent benchmarks:

Why waterfall beats single-source

The practical improvement from a 15-provider waterfall over a single-source tool on a 1,000-record US enterprise list is meaningful. Apollo's own database typically returns 580–650 matches on the same list. FullEnrich's cascade returns 700–800. That is 50–150 additional contacts per 1,000 records — a 10–15% improvement that compounds significantly at scale.

The waterfall advantage narrows in high-LinkedIn-density markets (US tech enterprise) where most providers draw from the same upstream sources. The advantage is most pronounced for roles with low social media presence — finance, legal, operations — where specialized providers in the cascade have data that LinkedIn-scraping tools simply do not.

FullEnrich Data Coverage: Email, Mobile, and Firmographics

Email coverage

Email enrichment is where FullEnrich is strongest. US enterprise and EU/UK enterprise coverage is deep because multiple providers in the cascade have independently indexed these markets. For the Fortune 1000 and equivalent EU enterprise, expect 80%+ hit rates. Coverage thins on SMBs — companies under 20 employees — because smaller organizations have less digital footprint for providers to index. APAC and LATAM email coverage is the weakest link in the waterfall, reflecting the overall sparseness of English-language professional data in those markets.

Mobile number coverage

FullEnrich sources mobile numbers through partner providers that provide Diamond-tier equivalent data — meaning verified, not just scraped. Mobile hit rates are consistently lower than email across all regions because fewer providers in the cascade have verified phone data. US enterprise mobile coverage at 45–60% is competitive with single-source tools but below Cognism Diamond Data for UK and EMEA senior executives, which is the gold standard for verified phone enrichment.

For teams where phone coverage is the primary requirement, Cognism remains the stronger option for UK/EMEA cold calling. For teams where email is primary and mobile is supplementary, FullEnrich delivers acceptable mobile coverage without paying Cognism's $15,000+ annual minimum.

Firmographic data (CompanyEnrich)

Company-level data — industry classification, headcount ranges, annual revenue estimates, tech stack, funding status — is not native to FullEnrich. It requires integration with CompanyEnrich, a complementary product designed to pair with FullEnrich's contact enrichment. The integration is straightforward via API or Zapier, but it means FullEnrich alone does not give you a complete enrichment picture. Teams that need contact + firmographic enrichment in a single API call may prefer SyncGTM or Clay where both are handled in one platform.

FullEnrich Integrations: How It Fits Your Stack

FullEnrich connects to the most common GTM stack components through a combination of native connectors, Zapier, and its REST API. The integration surface is intentionally minimal — FullEnrich is not trying to be a platform, just a high-quality enrichment layer that pipes into whatever tools you already use.

The missing integrations tell the product story clearly: no native Salesforce connector, no direct Outreach or Salesloft push, no real-time CRM field sync without Zapier glue. FullEnrich is a data service, not a platform. If you want enrichment that automatically updates CRM records without building Zapier workflows, look at SyncGTM's automated CRM enrichment or Apollo's native HubSpot/Salesforce connectors.

FullEnrich Pros: What It Does Well

• ✓
  Deepest waterfall in the price category. 15+ providers cascaded automatically delivers 10–15% higher hit rates on US enterprise lists than single-source tools. No other tool at $69–$359/mo matches this waterfall depth.
• ✓
  Transparent credit pricing. Published rates, no seat fees, failed lookups don't consume credits. You can calculate exact cost before committing. Rare in a category where most vendors hide pricing behind sales calls.
• ✓
  No seat fees. Cost scales with usage, not headcount. A 10-person team pays the same as a 1-person team on the same credit allocation. This makes FullEnrich significantly cheaper than per-user tools (Lusha, Kaspr) for mid-sized outbound teams.
• ✓
  API included on all plans. Bulk enrichment, CSV upload, and REST API access come with every tier — not locked to enterprise. This makes FullEnrich practical for technical teams and RevOps engineers who want programmatic access without a premium plan.
• ✓
  Clean product with a clear use case. FullEnrich does one thing and does it well. No feature bloat, no upsell to signals you don't need, no platform lock-in. If you need high-volume enrichment at predictable cost, the product is exactly what it says on the label.

FullEnrich Cons: Where It Falls Short

• No native outreach layer. FullEnrich enriches records but does not send emails, run sequences, or manage cadences. You need a separate tool — Instantly, Outreach, Apollo sequences — to actually reach prospects.
• No buying signals of any kind. No hiring surge detection, no funding alerts, no tech stack change monitoring. You get contact data only, with no indication of which companies are actively evaluating solutions.
• CRM-native enrichment requires API work or Zapier. Continuous automated enrichment directly into Salesforce or HubSpot fields is not a built-in feature — it requires custom integration effort.
• APAC and LATAM hit rates drop to 50–60%. If your ICP concentrates in Southeast Asia, Latin America, or non-English-speaking markets, waterfall coverage thins significantly.
• 15 providers is narrower than top alternatives. Clay's 75+ provider routing and SyncGTM's 40+ waterfall both give higher fill rates on edge cases — niche industries, SMB contacts, non-English names.
• No firmographics natively. Company-level data (industry, headcount, revenue) requires a separate CompanyEnrich integration rather than being part of the core product.

FullEnrich vs SyncGTM vs Clay vs Apollo

The enrichment category has fragmented into pure-enrichment tools (FullEnrich, Hunter), orchestration platforms (Clay), and integrated GTM platforms (SyncGTM, Apollo). Here is how the four main options compare across the dimensions that matter for enrichment decisions in 2026.

The honest take on each option

FullEnrich wins on pure enrichment hit rate at the lowest price point. It is the right choice if enrichment is all you need and you already have buying signals and outreach handled separately.

SyncGTM matches FullEnrich's waterfall depth (40+ providers vs. 15+) and adds the entire signal layer — hiring surges, funding rounds, tech stack changes, job changes — plus built- in outreach sequencing. At $99/mo vs. $69/mo for comparable enrichment credit allocations, the $30/mo premium buys you the signals and outreach that FullEnrich cannot provide. For teams that currently pay for FullEnrich + a signal tool + a sequencer separately, SyncGTM consolidates the stack at a lower total cost.

Clay offers the most flexible enrichment orchestration (75+ providers) but requires significant setup time, costs $149–$800/mo, and has a steep learning curve. It is the right choice for technical RevOps teams who want maximum customization and already know how to build Clay tables.

Apollo combines enrichment with outreach sequences and a proprietary database, but its single-source enrichment hit rate is lower than waterfall tools. The built-in sequencer is Apollo's differentiation, but it lacks buying signals and the enrichment quality falls short of waterfall alternatives on enterprise targets.

Who Should Use FullEnrich?

FullEnrich is the right tool in one specific scenario: you are a contact data ops team or RevOps engineer who needs best-in-class email and mobile enrichment hit rates, you already have a separate signal monitoring tool and a separate outreach sequencer, and you want the enrichment layer to be as cheap and accurate as possible without platform overhead.

Use FullEnrich if:

• Your ICP is US or EU enterprise and you are optimizing enrichment hit rate above 70%.
• You have 3+ people running enrichment and per-seat pricing from tools like Lusha is becoming expensive.
• You already use Clay, Apollo sequences, or a dedicated signal tool and just need a better enrichment provider in that stack.
• You want API access and programmatic enrichment without paying enterprise minimums.

Do not use FullEnrich if:

• You want enrichment, buying signals, and outreach in one platform. FullEnrich provides none of the last two.
• Your ICP is heavily APAC or LATAM where hit rates drop to 50–60%.
• Phone-verified mobile numbers for UK/EMEA cold calling are your primary need — Cognism Diamond Data is more accurate for that specific use case.
• You want automated CRM enrichment without building Zapier workflows. FullEnrich requires integration work for real-time CRM sync.
