Looking for the best lead enrichment tool for your RevOps stack?You’re in the right place. 

Whether you're optimizing speed-to-lead, automating qualification, or feeding better data into your AI models, the right enrichment platform can make or break your results.

Below, we break down 11 top tools—what each one does best, how they compare, and who they're built for—so you can choose with confidence.

Best lead enrichment tools, at a glance

‍

1. Default: Best all-in-one lead enrichment tool

Default is the overall best lead enrichment tool on this list. The main reason: it’s an all-in-one platform. Default not only enriches leads, but also captures, qualifies, routes, schedules, and nurtures them. And it does all this without the need for extensive (and expensive) integrations or developer support. 

Key features

• Real-time data enrichment built into no-code conversion forms—integrated data from Clearbit and Apollo.io to help maintain an accurate contact database
• Lead qualification models that leverage enrichment data, form data, CRM data, and behavioral data from product-led growth (PLG) funnels to ensure alignment with your ideal customer profile
• Automated lead routing and scheduling immediately upon conversion
• Advanced, flexible sales & marketing automation workflows built with a no-code, drag-and-drop interface 
• Dozens of sales and marketing software integrations

Pricing

Note: All editor seats are free, and you can kick the tires with a demo before committing, so you pay only for active seats and workflows that deliver real GTM value.

Where Default shines

• Real-time GTM orchestration: Built for high-velocity inbound teams that need to enrich, qualify, route, and schedule leads instantly—without relying on a patchwork of tools.
• AI-powered lead matching: Combines enrichment data and fuzzy logic to assign leads to the right rep automatically and accurately.
• Pre-submit visitor enrichment: Uses website intent signals and waterfall data providers to enrich anonymous traffic and trigger workflows before a form is submitted.

Where Default falls short

• Designed as a full-stack solution: Ideal for teams ready to replace their current inbound tools, not for those looking to plug enrichment into legacy systems.

Customer reviews

“Default replaces the need to buy multiple tools (data enrichment, lead routing, automated demo scheduling, automated workflows) and makes life far easier than attempting to handle multiple integrations across your RevOps data.” - Liam M., verified G2 reviewer

“Really easy to set up an inbound lead workflow. Default allows you to route leads based on form input and enrichment by other tools like Clearbit and Apollo. Follow-up mails, notification and CRM integrations mean that we no longer need to stitch 5 tools together to get the job done.” - Jules J., verified G2 reviewer

Who Default is best for

• High-velocity GTM teams: Perfect for marketing and sales teams dealing with rapid inbound lead flow.
• RevOps leaders: Ideal for teams looking to centralize and automate lead handling from form fill to meeting.

2. Apollo.io: Best lead enrichment tool for comprehensive data

‍

As lead enrichment tools go, Apollo.io is one of the best in the business. The platform’s extensive database with 200M+ contacts and 60M+ companies is hard to beat. That’s one reason why our own lead enrichment software leverages their database. 

Key features

• Built-in lead enrichment from an extensive contact and company database with demographic data, firmographic data, and more
• Advanced search filters that include behavioral and buyer intent signals
• Marketing automation sequences and email campaigns based on custom filters and triggers for qualified outreach
• Integration with major CRMs and marketing and sales platforms
• Analytics, reporting, and AI-based functionality

Pricing

Note: Trial plans include 100 credits and nearly full feature access. To use non-Gmail/Microsoft emails for campaigns, you’ll need a paid plan or sales-enabled trial. The Organization plan is billed annually and requires a minimum of 3 seats.

​​Where Apollo shines

• Expansive B2B database: Access over 275M contacts and 70M companies, including buyer intent and technographic signals.
• Built-in engagement tools: Combine enrichment, email, dialer, and sequences in one streamlined outbound platform.
• Flexible enrichment options: Enrich records via CRM, CSV, API, or real-time workflows for dynamic outreach.

Where Apollo falls short

• Data accuracy varies: Some records require manual cleanup, especially for direct dials and titles.
• Limitations on free tier: Lower plans restrict email exports, mobile numbers, and enrichment credits.

Customer reviews

“Apollo is very simple yet robust tool for email outreach as well as leads management. It has got numerous features like extensive people and company database and also data enrichment.” - Omkar G., verified G2 reviewer

Who Apollo is best for

• Outbound sales teams: For reps running volume-heavy, multi-channel outreach.
• Growth-stage startups: For budget-conscious teams scaling prospecting efforts.

3. Clearbit: Best lead enrichment tool for AI

‍

Image source: Clearbit

Default also uses Clearbit as one of our lead enrichment data sources. One thing that sets this tool apart is the use of AI to automatically detect changes and errors in the data, making adjustments in real time. 

This results in one of the most accurate and up-to-date contact databases on the market, which is probably why HubSpot acquired them last year. 

Key features

• Comprehensive database with 100+ attributes per contact (e.g. company size, contact information, industry, etc.)
• AI-powered change detection to enable automated record updates and ensure accurate contact data
• Powerful APIs and Webhooks make it easy to integrate with other sales technology (including Default)

Pricing

Where Clearbit shines

• Extensive data coverage: Enriches contacts with 100+ real-time firmographic, technographic, and intent data points.
• AI-powered updates: Continuously refreshes records using AI to ensure data accuracy and recency.
• Developer-friendly integrations: Robust APIs and webhooks make it easy to connect with CRMs and forms.

Where Clearbit falls short

• Premium pricing: High starting costs make it less accessible for smaller or early-stage teams.
• No native engagement tools: Doesn’t offer built-in outreach or list-building features—just raw data.

Customer reviews

“Account enrichment data is extremely high quality and the ease of integrations from form shortening to within-database batch jobs is wonderful.” - Hubilo V., verified G2 reviewer

“Not always accurate, definitely could use more frequent refresh. Also did not provide robust integrations that enabled us to easily action on that data.” - Brian Y., verified G2 reviewer

Who Clearbit is best for

• Enterprise GTM teams: For scaling companies enriching millions of CRM records.
• RevOps and data teams: For orgs with technical bandwidth to leverage APIs.

4. ZoomInfo: Best lead enrichment tool for B2B marketing

Key features

Who ZoomInfo is best for

• GTM ops leaders: For scaling organizations automating outreach and segmentation.

5. Cognism: Best lead enrichment tool for European data

‍

Image source: Cognism

Navigating the European data world isn’t for the faint of heart. Complex regulations and compliance standards make it difficult for companies who go it alone. That’s why many companies turn to Cognism's sales intelligence platform: their database is 100% secure and compliant with GDPR and CCPA requirements. 

Key features

• International database covering EMEA, NAM, and APAC that’s fully compliant with GDPR & CCPA
• Rigorous email and mobile phone validation standards (roughly 70M mobile numbers)

“The entire process for jumping into the Cognism App via Salesforce App Launcher to build a list and import is cumbersome and very nuanced -- so much so that many sellers lose motivation before they get the payout.” - Christina B., verified G2 reviewer

• EMEA-focused sales teams: For teams needing GDPR-safe data at scale.
• Signal-driven sellers: For reps timing outreach based on real-world company triggers.

6. FullContact: Best lead enrichment tool for identity resolution

‍

Image source: FullContact

Identity resolution can be a challenge not only for internal organizational security, but also inbound and outbound marketing and sales. If a lead comes to your website with a similar name to an existing contact, you’ll want to verify their identity to decide which type of outreach to engage with. 

FullContact is the leading lead enrichment solution for identity resolution. 

Key features

• Requires technical lift: API setup and integration demand developer support to realize full value.

Customer reviews

“The accuracy of the person's API. Unusable if it gets wrong. We have to validate before showing the result. Not so great coverage for people outside of the US.”  - Hitoshi K., verified G2 reviewer

Who FullContact is best for

• Enterprise marketing teams: For those building privacy-compliant, unified customer profiles.
• Data-centric orgs: For companies prioritizing identity resolution and data cleanliness.

7. Pipl: Best lead enrichment tool for spam & fraud detection

‍

Image source: Pipl

Like FullContact, Pipl is built primarily as an identity resolution tool. However, Pipl’s main value prop is the elimination of spam, crime, and fraud within online communities. For marketing and sales teams, Pipl helps online commerce and social media marketers automate solutions to enable scalability while mitigating risk. 

Key features

• Access a Trust Score for each user action through a simple API integration
• Customize your own thresholds for approvals, denials, or actions requiring additional vetting

Customer reviews

• Trust-based platforms: For businesses requiring confidence scores before approval or access.

How does the lead enrichment process work? 

Lead enrichment is a multi-step process, most of which happens before you’ll see the data in your software. If you’re looking to include any of the above tools in your RevOps tech stack, you may or may not be getting into the weeds of how enrichment works. 

Data collection

The first step in lead enrichment is to collect data from various sources: public databases, social media, business directories, and proprietary sources. The more sources you have, the more comprehensive and accurate your database will be. 

The most common forms of data collection are using algorithm and scraping techniques to access and classify the most relevant information. 

Data classification

The data must then be classified and organized into a useful format. For example, having an email address and phone number isn’t helpful if those data are classified as “Notes” and “Birthdate.” 

If the scraper or algorithm has access to the relevant metadata, this process is relatively straightforward. Short of that, you can use typical formatting conventions to classify data (e.g., any text ending in @ + a recognizable domain is classified as “email address” or any 10-digit number is classified as “phone number.)”

Otherwise, there are a number of machine learning algorithms that can accelerate data classification. 

Data append

Data append technically happens at multiple points in the lead enrichment process. 

When a new contact record is created, an enrichment tool can append scraped data to existing, proprietary records. When contact records are updated, the tool can append the new data to the existing record in real time. 

Data append also takes place when lead enrichment databases add new sources or data points to their records. 

Data validation

Any high-quality lead enrichment tool will use standard validation techniques to maintain its quality and accuracy. Common strategies include:

• Cross-referencing information across multiple sources
• Using third-party data verification services for contact information
• Using AI to identify and verify employment status, job titles, and other information

Data integration

Once your enrichment tool has captured and validated the data, the next step is to integrate it with your marketing and sales technology. This is usually the point of the process where you’ll start to see the magic happen.

There are a variety of integration practices that work with different technologies. These include ETL (Extract, Transform, Load), ELT (Extract, Load, Transform), data streaming, APIs, and more. 

Data updates

Any piece of data you have has a limited shelf life.

The key to ongoing lead enrichment success is the ability to continually update your data in real time. Job changes, updated contact info, or real-time behavioral and intent data can change a lead’s qualification status, so it’s important to get these updates as quickly and efficiently as possible.

Benefits of lead enrichment tools

Lead enrichment tools benefit sales and marketing teams in a variety of ways. Here are some ways it can dramatically improve your sales efforts.

Faster lead qualification & scoring

The biggest benefit is the acceleration of inbound lead qualification and speed-to-lead. A typical conversion-optimized lead form only captures 3-5 data fields. That’s never enough to determine whether the lead is a good fit or ready to buy.

Enrichment data provides a more holistic picture not only of who the lead is, but where they sit in their buying journey. This enables salespeople to qualify and reach out faster and improve the likelihood of a response, scheduled sales meeting, and purchase. 

Reduced lead research time

Most sales reps find themselves in a time management bind.

The more they know about their leads, the more effective their outreach and sales conversations will be. However, if they spend all their time doing research, they’re not out there initiating conversations and finding new business. 

Lead enrichment tools help alleviate this challenge. By capturing data and leveraging AI to summarize key points, these tools can help reps significantly reduce research time without a corresponding lag in sales effectiveness. 

More personalized marketing & sales outreach

A recent Forrester-Adobe study showed that 72% of B2B leads expect highly personalized content from the products and services they buy from. To accomplish this, sales reps need far more data than a typical research process will surface. 

Lead enrichment enables more targeted engagement, including customized messages and offers that resonate with individual lead preferences and pain points. When you add intent and behavioral data into the mix, you can also add timeliness into the mix, further increasing the likelihood of a conversion.  

More effective lead nurturing

The typical lead-nurturing workflow is a static funnel, where all leads receive the same messaging regardless of how relevant it is to them. This approach can kill your credibility—the opposite of its intended effect. 

With enrichment data + a highly flexible, no-code automation solution like Default, you can build dynamic workflows that allow for hyper-personalized automated outreach.

Your messages can vary based on the lead’s behavior, intent, demographics, and more. 

Better segmentation

The more nuanced your segmentation, the more effective and personalized your messaging—one-to-one, batch, and automated—can be. With lead enrichment tools, you can segment based on a combination of factors: industry, job title, intent, behaviors, and more. 

Improved AI-enabled solutions

AI rises and falls based on the data used to train and update it. The more data you have on your leads, the better your AI models can use predictive analytics in your lead scoring models, lead routing software, and workflow solutions. 

How to choose the best lead enrichment tool

A number of factors can play into choosing the best lead enrichment tool to help execute your sales strategies. Here are some of the most important things to consider so you can ensure you're getting the best insights into your potential customers.

Data sourcing

Where does your lead enrichment tool get its data?

This is the first place you should start. Many lead enrichment solutions source data exclusively from public sources, essentially making them glorified aggregation tools. While this can be helpful and save time, you can do better.

The best lead enrichment tools source data from a combination of public and private sources. Apollo.io, for example, has two million providers within their network. 

Default enriches leads in real time using data from multiple sources—including Clearbit and Apollo.io—so you can count on a more accurate and up-to-date contact record.

Data validation, updates, & quality

Knowing where the data comes from is only the first step.

The next step is to see how they validate and update the data to maintain its overall quality. This is one area where AI can play an important role. 

For example, Clearbit uses AI to identify data changes and update them in real time. Plus, the more data sources a lead enrichment tool has at its disposal, the more effectively it can automate updates. 

Data velocity

For lead enrichment to effectively support modern marketing campaigns, your platforms must have a high data velocity.

You can’t wait an hour or more for a contact record to update. It’s critical that the data reach its destination as quickly as possible. This applies both to the initial conversion and subsequent record changes. 

Default enriches, qualifies, routes, and schedules leads instantly, helping inbound teams move from form fill to meeting in seconds—not hours.

Integrations & automations

Enriched data isn’t useful unless it drives action. That means your enrichment tool should integrate seamlessly with forms, CRMs, scheduling tools, and automation workflows.

The goal: fewer manual tasks and faster, smarter handoffs between systems.

Default builds automation directly into the platform—no need to manage multiple tools just to qualify, route, or follow up with a lead.

AI-powered capabilities

Although the role of AI in the broader GTM and RevOps ecosystem is still a matter of debate, we’ve found that AI provides a ton of value when it comes to lead enrichment. Some specific use cases we’ve found include:

• Automatically identifying changes in data and updating records across the board
• Summarizing enrichment data to accelerate sales reps’ lead qualification flows
• Providing more data for predictive lead scoring models, improving their accuracy
• Analyzing contact records for more dynamic lead routing and workflow customizations

Default uses AI to analyze lead data and optimize everything from lead scoring to rep matching—so you can scale intelligently without losing speed or accuracy.

Price

Lead enrichment tools are certainly worth the investment. But too many options are overpriced, usually because they come with a bunch of paid or add-on features you don’t really need. We highly recommend looking at the various pricing tiers for each tool to determine where you can get the most value. 

Default offers transparent pricing that scales with your workflow volume and active users—so you only pay for what actually drives GTM results.

How to automate the lead enrichment process

Lead enrichment can sometimes run the risk of slowing the sales process. With more data at their disposal, salespeople can often spend more time qualifying leads and planning more personalized outreach.

To avoid this slowdown, it’s critical to automate your lead enrichment processes. Here are three tips to keep your inbound flows moving quickly:

• Choose a lead enrichment tool that integrates directly with the rest of your inbound flow to avoid potential data loss or lead deceleration
• Use AI to aggregate and summarize key data on potential customers—this reduces lead qualification times by 31%
• Set up dynamic, sophisticated lead routing flows to account for the high amounts of demographic, behavioral, and intent data at your disposal—these can be based either on rules-based flows, or AI-enabled predictive analytics

Once your inbound funnels start generating hundreds of leads per month, you’ll be glad you set up these automations. 

Here are some examples of lead enrichment templates that are automatically available through Default:

Enrich & route leads from inbound forms

Lead enrichment tools FAQ

What is a lead enrichment tool? 

A lead enrichment tool is software that automatically adds third-party data to a lead’s contact and account records. Examples of data used in lead enrichment include demographics, firmographics, behavioral data, and intent data. 

How do you enrich leads?

Lead enrichment requires four components: 1) a CRM where the contact & account records live, 2) a third-party enrichment data source, 3) a common datapoint for record matching & verification (typically name and email address), 4) an API that pulls enrichment data from the third-party into your CRM. 

Can you automate lead enrichment?

Yes, you can automate lead enrichment. This process involves the use of APIs to pull in third-party data at the moment of conversion. From there, you can build additional rules-based and AI-enabled automations based on your newly available data.
