FullEnrich Review

For UK revenue teams that find single-source contact databases incomplete, FullEnrich provides a waterfall enrichment layer that sequences 15 to 20+ data vendors, verifies returned records and charges credits only for successful matches. It combines email and mobile discovery, regional provider routing, API/webhook delivery and an MCP server for AI-agent workflows. The free trial includes 50 credits; paid plans start at approximately £22.90/month.

Platform Overview

FullEnrich is a Paris-based B2B data orchestration and sales-enablement platform founded in 2023. It was created to address the data decay and coverage gaps that leave single-vendor prospecting searches incomplete. Rather than acting as one static contact database, it routes a prospect query across a sequence of third-party sources until a verified result is found or the waterfall is exhausted.

The platform is aimed at UK and European SMEs, outbound agencies, RevOps teams, recruitment firms and enterprise sales development organisations. Its research profile reports deployments across more than 1,000 commercial teams and highlights a 4.8/5 G2 score; this review applies a more conservative 4.6/5 assessment based on the platform's feature set, usage model and UK implementation considerations.

What is FullEnrich?

FullEnrich is a B2B contact enrichment platform centred on waterfall orchestration. Users provide a name, job title and company domain, then the platform queries a prioritised network of 15 to 20+ vendors. It stops when it returns verified contact data, with failed searches not consuming credits. Regional logic can reorder providers for UK, EMEA, North American and other markets.

Beyond enrichment, FullEnrich provides people and company search, asynchronous REST APIs, webhooks and a Model Context Protocol (MCP) server. The MCP capability allows compatible AI agents to initiate enrichment, reverse lookup and search workflows within a controlled RevOps process.

Key Features for UK Businesses

1. Multi-Provider Sequential Waterfall Enrichment Engine

FullEnrich routes each lookup through 15 to 20+ premium providers, including sources cited in the research such as Apollo, Dropcontact, Hunter, Datagma, Findymail, RocketReach and BetterContact. It stops once a verified record is returned, helping teams avoid the empty-result problem of a single database.

• Technical specifications: asynchronous enrichment, vendor fallback and credits charged only for verified results.
• UK application: A London fintech uploading 1,000 European risk-leader records can use the waterfall to improve coverage beyond the roughly 450 contacts expected from a typical single source.

2. Dynamic Location-Based Provider Routing

The platform adjusts provider order using geographical and firmographic signals. This matters where a source that performs well in North America has lower coverage in the UK, DACH or wider EMEA.

• Technical specifications: supported routing across US/Canada, EMEA, LATAM and APAC, with EMEA email match rates reported up to 84%.
• UK application: A UK B2B SaaS team expanding into Germany, Austria and Switzerland can prioritise European sources without separately managing regional databases.

3. Triple-Stage Email Verification & Bounce Prevention

Returned emails pass through three verification stages intended to filter invalid, risky and catch-all addresses. The research reports that approximately 30% of inaccurate raw records can be removed and describes a target verified-email bounce rate below 1%.

• Technical specifications: syntax, mail-server and catch-all checks across three verification layers.
• UK application: A Manchester outbound agency can vet client lists before loading them into an email-engagement platform, helping protect sending-domain reputation.

4. Mobile-First Direct Dial Discovery & Free HQ Landline

FullEnrich prioritises verified direct mobile numbers while returning corporate HQ landlines and switchboards without a credit charge. Direct mobiles consume 10 credits, so teams should allocate phone enrichment to high-value accounts.

• Technical specifications: direct mobiles at 10 credits; free switchboard numbers; North American line-ownership matching.
• UK application: A UK recruitment agency sourcing FTSE 250 executives can combine a free switchboard fallback with direct-dial discovery for priority candidates.

5. B2B People & Company Search Engine

The built-in search interface provides more than 30 people and company filters, including role, seniority, location, headcount, industry, tenure and social-profile data. Teams can build a list before running it through the enrichment waterfall.

• Technical specifications: people and company search endpoints, CSV export and synchronous REST search APIs.
• UK application: A cybersecurity supplier can identify UK heads of information security at organisations with 200 to 1,000 employees, then enrich the prioritised list.

6. MCP Server & AI Agent Integration

FullEnrich exposes enrichment, reverse lookup and people/company search capabilities through an MCP server. It supports AI-agent use cases where a controlled workflow identifies prospects, enriches them and hands the data to a CRM.

• Technical specifications: MCP support with OAuth 2.0 or API-key authentication.
• UK application: A growth consultancy can let a configured agent research UK SaaS companies, enrich named decision-makers and prepare records for HubSpot review.

7. Asynchronous REST API & Enterprise Webhooks

Because waterfall searches may take 30 to 90 seconds, FullEnrich uses an asynchronous enrichment model. A request returns an acknowledgement while the completed result is delivered to a webhook, with the research describing up to five retry attempts.

• Technical specifications: API v2 enrichment, reverse lookup, people search, company search and webhook retries.
• UK application: A SaaS team can enrich a business signup through a webhook workflow and route the resulting firmographic context to the relevant sales queue.

8. Stack Integrations for RevOps Workflows

FullEnrich fits into existing sales stacks through Clay, Zapier, Make, n8n, direct APIs and webhooks. The research cites compatibility with HubSpot, Salesforce, Pipedrive and Attio, plus outreach and operational tools through middleware.

• Technical specifications: native Clay provider integration plus automation-builder and CRM connections.
• UK application: An outbound agency can send target-company data from Clay to FullEnrich, then pass verified contacts into its CRM after an appropriate compliance review.

Pricing for UK Businesses

FullEnrich uses credits rather than per-seat pricing. The figures below are approximate GBP conversions from the research's USD pricing and are presented for budgeting only; billing is stated as native USD. A verified work email uses one credit, a personal email three credits and a direct mobile ten credits. Failed searches and HQ landlines are free.

Recommended plan: Pro at approximately £43.50/month is the most balanced starting point for UK teams that need API/webhook access, integrations and MCP support. Measure actual email and mobile use before committing to higher-volume credits.

UK Compliance & Security

FullEnrich states that it supports EU GDPR and UK GDPR obligations, provides a data processing agreement with Standard Contractual Clauses and UK transfer addendums, and hosts core infrastructure in EU-based AWS regions. The research also cites SOC 2 Type II certification, data-subject rights support and an opt-out route.

These capabilities do not remove a UK customer's responsibilities. Organisations should document an appropriate lawful basis, ensure privacy information and outreach processes are suitable for the use of B2B data, configure retention and access controls, and honour objections. Regional routing can support EMEA coverage, while verification helps reduce invalid-email risk; neither should be treated as consent for marketing.

Pros & Cons

Strengths

• Waterfall coverage across 15 to 20+ providers can improve contact discovery.
• Credits are charged for successful verified matches rather than failed lookups.
• Unlimited user seats avoid a per-seat pricing model.
• Triple-stage email verification is designed to reduce risky records.
• MCP server support is useful for carefully controlled AI-agent workflows.
• Free HQ landlines provide a zero-credit fallback alongside mobile discovery.

Limitations

• High-volume credit economics may not suit every large enterprise use case.
• It is an enrichment layer, not a native email-sequencing product.
• CRM field synchronisation commonly needs webhooks or middleware.
• Mobile coverage varies by region, particularly in APAC and LATAM.

UK Industry Use Cases

Fintech Prospecting

London financial-technology teams can enrich European risk and compliance decision-maker lists, then use verified results in a compliant account-based sales process.

Outbound Agencies

Agencies can consolidate multiple data lookups into one waterfall and use verification before passing suitable records into client-approved outreach systems.

Executive Recruitment

Recruiters can search leadership profiles, use free switchboards as a fallback and reserve direct-mobile credits for strategically important candidates.

SaaS Expansion into DACH

UK SaaS teams can use regional routing to prioritise EMEA sources when entering Germany, Austria and Switzerland.

RevOps Data Operations

RevOps teams can use API and webhook workflows to enrich inbound or target-account records while retaining human review before CRM activation.

Competitive Analysis

FullEnrich vs Apollo.io

Choose Apollo.io when you want a bundled database, prospecting and sequencing environment. Choose FullEnrich when the priority is an out-of-the-box waterfall and pay-for-results contact enrichment that can feed an existing sales stack.

FullEnrich vs Cognism

Cognism is a strong consideration for teams that need phone-heavy prospecting and a dedicated EMEA compliance focus under an enterprise contract. FullEnrich is more flexible for teams preferring monthly credits, lower upfront commitment and multi-vendor fallback.

FullEnrich vs ZoomInfo

ZoomInfo can suit large US-led organisations seeking deep company intelligence and intent features. FullEnrich is a lighter, transparent data-orchestration option for UK and European teams that value flexible credit billing, regional routing and API/MCP access.

Final Verdict for UK Businesses

FullEnrich is a compelling enrichment layer for UK sales, recruitment and RevOps teams that routinely encounter gaps in single-source contact databases. Its multi-provider waterfall, verification approach, result-based credits, EMEA routing and MCP support make it especially relevant for modern, integration-led outbound processes.

The principal trade-off is operational: it does not replace email sequencing, and its data must be used within a documented, compliant prospecting process. Teams should validate coverage against their ideal customer profile using the free credits, calculate email versus mobile credit consumption and ensure CRM/webhook controls are in place.

Rating: 4.6/5 — Highly recommended as a flexible, UK-relevant B2B enrichment data layer for teams that want stronger coverage than a single source can provide.
