Clay vs Clearbit for Data Enrichment (2026)
B2B data enrichment fills in the gaps on your contacts and accounts. Clay and Clearbit both do enrichment but represent different generations of the category. Clearbit is a traditional enrichment API with a fixed data source. Clay is a workflow platform that waterfalls across dozens of data providers. The competitive dynamics between them have shifted dramatically since HubSpot acquired Clearbit in late 2023.
Clay and Clearbit enrich B2B data differently. We compare waterfall enrichment, real-time APIs, pricing, and which fits your enrichment workflow.
Different Products, Different Categories
Clearbit is a data provider. You send them an email address or domain, they return enriched firmographic and contact data from their own database. The data comes from one source: Clearbit's proprietary dataset. Simple API, predictable results.
Clay is an enrichment orchestration platform. You send Clay a contact or company, and it queries across 75+ data providers (including Clearbit) in a waterfall sequence. If provider A doesn't have the data, Clay tries provider B, then C, and so on. You get the best available data regardless of which single provider has it.
This distinction matters enormously for hit rates. No single data provider covers every contact. Clearbit's match rate for US tech companies might be 80%, but it drops significantly for other verticals and geographies. Clay's waterfall approach typically achieves 85-95% match rates across segments by aggregating multiple sources.
Think of Clearbit as a single restaurant. Clay is a food court with 75 restaurants. If one doesn't have what you need, you walk to the next one.
Data Quality and Coverage
Clearbit's data quality for its coverage areas is strong. Their firmographic data (company size, revenue, industry, technology stack) is well-maintained for US-based tech and mid-market companies. Contact data (email, title, seniority) is reliable when they have a match.
Clearbit's weakness is coverage gaps. Small businesses, international companies, non-tech verticals, and recently changed records are common blind spots. When Clearbit doesn't have data, it returns nothing. You're stuck.
Clay's quality depends on which underlying providers it queries. Because Clay orchestrates across providers like Apollo, ZoomInfo, Cognism, and others, the aggregate quality can exceed any single provider. Clay also allows you to configure quality rules (prefer provider A for emails, provider B for phone numbers).
The trade-off is consistency. Clearbit data always comes from one source with uniform formatting. Clay data may come from different providers with slightly different formatting, field names, or freshness. Normalization is needed downstream.
For RevOps teams that care about hit rates above all else, Clay's waterfall approach is superior. For teams that need consistent, predictable data from a simple API call, Clearbit's single-source model is cleaner.
One quality consideration often overlooked: data freshness. Clearbit maintains a single dataset and controls update frequency. Clay's waterfall pulls from providers with varying update cadences. A phone number from one provider might be current while another returns a number from 18 months ago. Cross-referencing multiple sources helps, but freshness varies.
The HubSpot Acquisition Factor
HubSpot acquired Clearbit in late 2023, and the integration has deepened since. Clearbit enrichment is now built into HubSpot's CRM, providing automatic contact and company enrichment for HubSpot customers at no additional cost on certain plans.
This changes the competitive calculation. If you're a HubSpot customer, Clearbit enrichment is essentially free. The data fills in firmographic fields, identifies website visitors, and enriches form submissions automatically. For basic enrichment needs, there's no reason to pay for a separate tool.
The limitation is that HubSpot-Clearbit enrichment is tied to HubSpot's ecosystem. If your CRM is Salesforce, you can still use Clearbit's API, but you lose the native integration advantages. And Clearbit's standalone API pricing has become less competitive as HubSpot focuses on bundling.
Clay operates independently of any CRM and works equally well with Salesforce, HubSpot, or any other system. If you're on Salesforce or want CRM-agnostic enrichment, Clay is the more flexible option.
Workflow and Automation Capabilities
Clearbit's workflow capabilities are limited to enrichment triggers. You can enrich on form submission, on record creation, or via scheduled batch enrichment. The tool does one thing (enrichment) and connects to your CRM or marketing automation platform.
Clay is a full workflow platform. Beyond enrichment, you can build multi-step sequences: find companies matching criteria, enrich them, score them, write personalized outreach copy using AI, and push to your outreach tool. Clay replaces an entire prospecting workflow, not just the enrichment step.
Clay's AI features (writing personalized email intros, researching companies, qualifying leads based on custom criteria) add capabilities that Clearbit doesn't offer at all. For outbound sales teams, Clay is a prospecting platform that includes enrichment. Clearbit is an enrichment tool.
For teams that need enrichment as part of a larger outbound workflow, Clay delivers more value per dollar. For teams that need a simple enrichment API to keep CRM records current, Clearbit (especially within HubSpot) is sufficient.
Pricing: Complex vs Simple
Clearbit's pricing has shifted since the HubSpot acquisition. Standalone API pricing starts around $15,000/year for mid-market volumes. HubSpot customers get basic Clearbit enrichment included in Marketing Hub and Sales Hub Professional+ plans.
Clay's pricing is credit-based. Plans start at $134/month (Explorer) with limited credits. The Pro plan ($314/month) and Team plan ($720/month) increase credit allotments. Each enrichment action, AI operation, or data provider query consumes credits. A typical full enrichment of one contact (waterfall across 3-4 providers) uses 5-15 credits.
For straight enrichment API usage, Clearbit is often cheaper on a per-record basis, especially for HubSpot customers who get it bundled. For enrichment-plus-workflow usage, Clay's all-in-one approach can be more cost-effective than buying separate tools for enrichment, research, and personalization.
Hidden cost consideration: Clay charges separately for premium data provider access on top of base credits. Using ZoomInfo or Cognism through Clay requires those providers' own pricing agreements. The waterfall only includes providers where you have access or where Clay has bulk pricing.
Budget planning tip: run a small test batch through Clay before committing to a plan. Enrich 100 contacts and track credit consumption per contact. Multiply by your expected monthly volume to estimate real costs. The per-contact credit usage varies significantly based on how many waterfall providers you enable.
Integration and Data Flow
Clearbit integrates natively with HubSpot (owned by the same company), Salesforce, Marketo, and Slack. The Salesforce integration pushes enriched data directly to contact and account records. The API is REST-based and well-documented for custom implementations.
Clay integrates with CRMs (Salesforce, HubSpot), outreach tools (Outreach, Salesloft, Lemlist, Instantly), and data warehouses. Clay can pull records from your CRM, enrich them, and push updated data back. It can also push to outreach tools, creating a smooth prospecting pipeline.
For data teams that want enrichment data in their warehouse, both tools can feed warehouse pipelines. Clay's CSV export and API make it straightforward to route enriched data to any destination. Clearbit's webhooks and API serve the same purpose.
The integration difference that matters most is the outbound workflow. Clay connects enrichment directly to outreach execution. With Clearbit, you enrich data and then manually (or via another tool) route it to your outreach platform. Clay eliminates a step.
Our Verdict: Clay for Outbound, Clearbit for Passive Enrichment
Clay wins for teams that do active outbound prospecting. The waterfall enrichment, AI personalization, and outreach tool integrations make it the best enrichment-to-action platform on the market. If your team builds target lists, enriches contacts, and runs personalized outreach, Clay is the clear choice.
Clearbit wins for passive, ongoing CRM enrichment, especially within HubSpot. If you need to automatically enrich every new contact that enters your CRM without building workflows, Clearbit's set-and-forget approach is simpler and cheaper (often free for HubSpot users).
For Salesforce-based teams doing outbound, Clay is the recommendation. For HubSpot-based teams focused on inbound, Clearbit's native integration is hard to beat on convenience.
Many teams use both. Clearbit for baseline CRM enrichment (keep records current automatically) and Clay for targeted enrichment campaigns (build a list of 500 target accounts and enrich them deeply for an outbound push). This combination gets you the best of both approaches.
The broader trend in enrichment is moving toward multi-source waterfalls and away from single-provider dependency. Clay represents where the market is heading. Clearbit represents the previous generation. For teams making a new investment, Clay is the forward-looking choice. For existing Clearbit users on HubSpot, there's no urgency to switch.

Frequently Asked Questions
Does Clay replace ZoomInfo for enrichment?
Clay can query ZoomInfo as one of its waterfall providers, but you need a ZoomInfo account or credits. Clay doesn't replace ZoomInfo's database. It orchestrates across ZoomInfo and other providers to maximize coverage. For teams that only need ZoomInfo data, using ZoomInfo directly is simpler.
Is Clearbit still a standalone product after the HubSpot acquisition?
Clearbit's API remains available as a standalone product, but the company's focus has shifted toward HubSpot integration. Standalone API customers report less product development and support attention compared to pre-acquisition. The writing is on the wall for Clearbit as an independent platform.
How accurate is Clay's waterfall enrichment?
Accuracy depends on the underlying providers in the waterfall. Clay doesn't generate data; it queries existing providers. Match rates are higher (85-95%) because of the multi-source approach. Accuracy per matched record depends on which provider returned the data and how recently it was verified.
Can I use Clay for CRM enrichment automation?
Yes. Clay supports CRM-triggered workflows where new or updated records automatically go through enrichment waterfalls. However, this uses credits continuously, which gets expensive at scale. For high-volume passive enrichment, Clearbit or a built-in CRM enrichment feature may be more cost-effective.
