HubSpot's enrichment story changed in 2025. HubSpot Insights — the legacy enrichment product that many operations teams had built workflows around — was discontinued in March. Its replacement, Breeze Intelligence, arrived with a different coverage model, a credit-based pricing structure, and a meaningfully different set of capabilities. At the same time, the broader enrichment market saw Clay reach a $3.1 billion valuation (August 2025), single-source providers continue competing on data depth rather than coverage breadth, and a new category of HubSpot-native enrichment platforms begin to emerge.

The result is that the enrichment tool decision that was relatively straightforward two years ago — "should we use HubSpot Insights or Apollo?" — now involves significantly more options, more trade-offs, and more at stake. This guide covers the full landscape: what enrichment actually does, an honest assessment of the major tools, and a decision framework for choosing the right approach for your database and use case.

What Data Enrichment Actually Means (and What It Does Not Fix)

Data enrichment is the process of appending additional data to existing contact or company records from third-party sources. When a contact fills out a form with their name, email, and company, enrichment can append their job title, seniority level, LinkedIn URL, company employee count, revenue range, industry, and technology stack — information the contact did not self-report.

Enrichment improves completeness. It does not automatically improve accuracy or freshness. If a provider's data source is out of date, enrichment can populate a field with incorrect information — and an incorrect populated field can score worse in downstream operations than an empty field, because it creates false confidence.

Enrichment does not fix structural problems in your database architecture. If your intake forms do not capture critical fields, enrichment can compensate — but it is a downstream patch, not an upstream fix. If your duplicate rate is high, enrichment will enrich duplicates as well as real records, compounding the problem.

Enrichment also does not replace quality assessment. Knowing that a field is populated is different from knowing that the populated value is accurate and current. The strongest enrichment implementations pair data appending with freshness tracking and accuracy validation — so that the system knows not just what a field says, but when it was last verified and how confident the source is.

With those caveats in place, enrichment is genuinely one of the highest-leverage interventions available to RevOps teams. Moving a database from 45% critical field completeness to 80%+ through systematic enrichment has documented, measurable impact on deliverability, lead scoring accuracy, routing logic, and personalization quality.

HubSpot Breeze Intelligence

What it is: HubSpot's native enrichment product, replacing HubSpot Insights (discontinued March 2025). Powered by HubSpot's proprietary data network and AI layer.

Coverage: Approximately 40% of a typical B2B contact database. This number is higher for US-based technology contacts (potentially 60-70%) and lower for EU, APAC, or non-tech verticals (potentially 10-25%). Coverage is drawn from a single source — there is no waterfall fallback when Breeze cannot find a record.

What it enriches: Company firmographics (size, revenue, industry, technologies used), contact-level job title and seniority, company phone numbers. It does not support email discovery for contacts without an email address, and it does not provide personal mobile or direct phone numbers.

Pricing: Credit-based, credits expire monthly. Pricing is layered into HubSpot's Sales Hub and Marketing Hub tiers, with additional credits purchasable. Credits that are not consumed in a billing cycle are forfeited.

Key limitations:

Single source means a hard coverage ceiling (~40%)
No email discovery — cannot append emails to contacts who lack them
No direct dials — company phone only, not personal mobile
EU/non-US accuracy degrades significantly due to data localization constraints
No enrichment confidence scores or source attribution
No quality scoring on enriched records

Where it works: For US-centric tech databases, for teams that prioritize operational simplicity over coverage maximization, and for teams using the Buyer Intent feature for ABM targeting (the most differentiated Breeze capability).

Where it struggles: Globally distributed databases, use cases requiring email discovery or direct dials, organizations that need visibility into data quality trends beyond field population.

Clay

What it is: Clay is a data automation platform that has become the dominant tool for sophisticated waterfall enrichment workflows. It operates as an orchestration layer that sequences enrichment calls across 50+ data providers, applying custom logic to decide which provider to try next when a previous one returns no result.

Strengths:

Best-in-class waterfall orchestration. No other tool on the market sequences across as many data providers as Clay, or gives as much flexibility in defining the waterfall logic. For teams running complex enrichment operations across multiple ICPs, geographies, and use cases, Clay's orchestration capabilities are genuinely superior.

AI-augmented enrichment. Clay integrates large language model capabilities into its enrichment workflows, allowing you to generate custom fields (AI-written company summaries, persona classification, custom research prompts) that no traditional enrichment provider can produce. This is increasingly central to high-end personalization-at-scale use cases.

Proven at scale. Clay has significant adoption among growth agencies, PLG companies, and sophisticated RevOps teams running high-volume enrichment operations. The ecosystem of templates and community resources is extensive.

Weaknesses:

HubSpot integration reliability. The HubSpot integration in Clay has had documented issues with sync reliability, field mapping consistency, and workflow triggering. Teams using Clay as their primary enrichment layer for HubSpot have reported needing significant technical attention to maintain the integration. This is not a universal experience, but it is common enough to factor into your evaluation.

Price point. Clay's Pro tier starts at $800/month. The Starter tier ($149/month) has sufficient data credit limits for modest operations, but most production enrichment use cases require Pro. For the capabilities Clay delivers, the price is arguably justified — but it is a material budget commitment for a mid-market RevOps team.

No quality scoring. Clay enriches fields. It does not assess whether your database, in aggregate, is getting healthier or degrading. There is no grade distribution, no field-level freshness tracking, no quality trend reporting. You have better data after Clay runs — but you do not have better visibility into your data quality posture.

Steep learning curve. Clay is a powerful tool that rewards investment in understanding its model. Teams that deploy Clay without technical resources or dedicated time to learn the platform consistently underutilize it. The templates are helpful but do not substitute for understanding how to build custom waterfall logic.

Not designed for HubSpot Admins. Clay is primarily used by technical operators, growth engineers, and data-savvy RevOps professionals. The tool assumes comfort with API concepts, conditional logic, and data transformation. Non-technical HubSpot Admins typically need support to deploy it effectively.

Single-Source Providers: Clearbit, Apollo, ZoomInfo, Cognism

These tools share a common model: deep coverage from a single proprietary database, with direct HubSpot integration (usually native or through Zapier/Make). They differ primarily in their data depth specialization and geographic coverage.

Clearbit (now part of HubSpot)

Clearbit was acquired by HubSpot in 2023 and has been progressively integrated into Breeze Intelligence. Standalone Clearbit as a separate product is largely sunset for new customers. Its data assets now power parts of Breeze Intelligence's coverage.

Apollo

Apollo has become one of the most popular all-in-one sales intelligence and enrichment tools for SMB and mid-market teams. Its contact and company database has strong coverage in North American technology, with improving coverage in other geographies. Apollo's free tier and low-cost paid tiers make it accessible for teams running modest enrichment volumes.

Strengths: Strong email discovery (finding email addresses for contacts without one), large contact database, low price point at smaller volumes, built-in sales engagement features.

Weaknesses: Single source means hard coverage ceiling. EU accuracy is inconsistent. Data freshness varies significantly by record age and geography. Direct phone coverage is weaker than specialist providers.

Best for: Outbound-focused teams that need email discovery and are primarily targeting US-based contacts, particularly in the technology sector.

ZoomInfo

ZoomInfo is the dominant enterprise-tier B2B data platform in North America, with the deepest direct phone and mobile number database in the market. Its coverage for enterprise accounts in the US is best-in-class.

Strengths: Strongest direct phone database available. Enterprise-level firmographic depth. Intent data integration. Very strong US enterprise coverage.

Weaknesses: Price is enterprise-tier — contracts typically start at $15,000-20,000/year and scale from there. This makes ZoomInfo inaccessible for most SMB or early mid-market teams. Single-source coverage outside the US is weaker than marketing suggests. Sales process is relationship-intensive.

Best for: Enterprise outbound teams for whom direct dials are critical and budget is not a constraint.

Cognism

Cognism is the leading single-source provider for European B2B data, with particularly strong mobile and direct phone coverage in the UK, DACH, Nordics, and Benelux. Its GDPR compliance positioning is the strongest in the market, making it the default choice for teams running outbound into European markets.

Strengths: Best European mobile phone coverage available. Strong GDPR compliance infrastructure. Very good email deliverability rates on its contact data.

Weaknesses: Single source. North American coverage is growing but not at the depth of ZoomInfo or Apollo. Price is mid-to-high market.

Best for: Teams with significant European outbound motion, or any team where mobile phone coverage in EU geographies is a priority.

Waterfall Enrichment vs. Single-Source: Why Coverage Matters

The fundamental trade-off in enrichment tool selection is coverage versus simplicity. Single-source tools are simple to integrate and operate. Waterfall approaches maximize coverage at the cost of orchestration complexity.

The math on this trade-off is straightforward. If Provider A covers 40% of your database, and you use Provider A only, you leave 60% of your records unenriched. If you add Provider B (covering a different 30% of the remaining unenriched records), you reach approximately 58% overall coverage. Add Provider C, and you reach 70%. With 5-6 providers in a well-designed waterfall, you typically reach 80-90% coverage — meaning 2x to 2.5x the enrichment completeness of any single-source tool.

The aggregate coverage number matters more than it might initially appear, because the records that single-source tools cannot find are not randomly distributed. They tend to be concentrated in specific geographies (EU, APAC, LatAm), specific company types (smaller companies, non-tech verticals, newer companies without extensive web presence), and specific contact profiles (individual contributors, non-executive roles). These are often exactly the segments where your ICP lives, or where your database has accumulated the most decay.

Waterfall enrichment also provides resilience. If a provider's coverage degrades in a particular segment, the waterfall can route around it using other providers. Single-source tools have no equivalent fallback.

The operational overhead of waterfall enrichment is real. Managing multiple API keys, handling provider conflicts when two sources return different values for the same field, normalizing data formats across providers, and maintaining the orchestration logic as providers change their APIs — these are non-trivial engineering and operational tasks. The question is not whether waterfall is better than single-source (it is, on coverage) but whether the coverage gains justify the operational investment for your specific situation.

What to Look for in an Enrichment Tool: Evaluation Criteria

When evaluating enrichment tools, use these criteria to structure your assessment:

Coverage rate on your actual database, not benchmark marketing numbers. Ask vendors for a proof-of-concept against a representative sample of your database. Give them 500 records and ask for their coverage rate on your specific population. The difference between a vendor's claimed coverage rate and their actual coverage rate on your database can be 20-30 percentage points.

Geographic coverage matching your ICP distribution. If 40% of your ICP is European, a tool with strong US coverage and weak EU coverage is solving the wrong problem. Map your ICP geography against each vendor's geographic coverage claims, and verify with POC results.

Email discovery vs. firmographic enrichment. These are different capabilities. Email discovery (finding an email address for a contact who does not have one) requires a different data source than firmographic enrichment (finding company size, industry, technology stack). Confirm that the tool you are evaluating covers the specific use case you need.

Direct phone and mobile coverage. If outbound calling is part of your sales motion, verify the tool's direct dial coverage rate specifically — not just phone coverage, which often means company main lines.

Integration reliability with HubSpot. Native HubSpot integrations are not all equal. Evaluate the integration on: field mapping flexibility, sync reliability, support for HubSpot Workflows triggers, and the vendor's track record on maintaining the integration through HubSpot API changes.

Data freshness and source transparency. Does the tool tell you when a field value was last verified? Does it indicate which source contributed a given value? This information is critical for building accurate freshness tracking and for resolving conflicts when values seem incorrect.

Quality scoring on enriched data. After enrichment runs, do you have better visibility into your database quality — or do you just have more populated fields? Quality scoring that persists enriched data as graded records is significantly more useful for ongoing operations than enrichment that just fills fields.

BYOK (Bring Your Own Key) support. If you already have contracts with data providers (Apollo, ZoomInfo, Cognism), look for tools that allow you to bring your existing API keys rather than paying the tool's markup on those same providers. This can substantially reduce total cost of ownership.

MarketingSoda Refine: What We Are Building

MarketingSoda Refine™ is a pre-launch HubSpot-native data quality and enrichment platform designed specifically for the gaps described in this guide. The core approach:

Waterfall enrichment across 6+ providers (Apollo, Cognism, ZoomInfo, Hunter.io, Clearbit, ZeroBounce), achieving 80-95% field coverage versus the ~40% ceiling of single-source tools, with BYOK support for teams that already have provider contracts.

Per-record quality scoring across the seven dimensions described in Post 4 — completeness, accuracy, freshness, validity, consistency, uniqueness, and enrichment coverage — expressed as an A-F grade per record, visible as HubSpot properties and usable in workflows, lists, and reports.

Quality gates that block campaigns and sequences until contacts meet defined grade thresholds, replacing manual list scrubbing with automated enforcement.

Automated remediation that fires enrichment automatically when a record's quality score drops — no manual trigger required.

Probabilistic deduplication using a five-layer matching engine that surfaces duplicates exact-match tools miss, with auto-merge above 95% confidence, human review queue for 70-95%, and merge revert within 30 days via pre-merge snapshots.

We are building for the Marketing Ops and RevOps practitioners who have outgrown single-source enrichment, found waterfall orchestration tools too complex to maintain, and want a purpose-built HubSpot-native solution that handles enrichment, quality scoring, and remediation in one place.

We are pre-launch and inviting early access participants. Join the waitlist for MarketingSoda Refine
