HubSpot’s acquisition of Clearbit changed the B2B data enrichment landscape. What was once a standalone API for contact and company data is now Breeze Intelligence, bundled into HubSpot’s ecosystem. If you were using Clearbit independently or integrating it into a non-HubSpot stack, the rebrand forces a decision: commit to HubSpot or find an alternative.
The search for replacements reveals something else. The category itself has splintered. Some teams need a pure enrichment API to feed existing workflows. Others want visitor identification that turns anonymous traffic into named accounts. Still others are looking for platforms that identify, enrich, and act on that intelligence without manual handoffs between tools.
This guide breaks down the alternatives across those categories, so you can find the right fit for how your team actually works.
Compare Clearbit alternatives by what your growth team needs after enrichment
Key takeaways
- The best Clearbit alternative depends on what you used Clearbit for. Some teams need straightforward contact and company enrichment, while others need visitor identification, sales intelligence, or a broader growth workflow.
- Ploy is a strong fit for teams that want to go beyond enrichment. It combines visitor identification, CRM sync, website tools, personalized pages, and outreach so you can act on buyer interest without stitching together several platforms.
- Data-focused tools make more sense when enrichment is the main priority. They work well for teams that already have established CRM, sales, and marketing workflows and only need better company or contact data.
- Visitor identification tools are better suited to teams trying to uncover anonymous website demand. They show which companies or people are already researching your business before a form submission.
- Enterprise alternatives offer deeper intent and account-based marketing capabilities, but they usually require more setup and ongoing management. Smaller teams will often get more value from tools that are faster to deploy and easier to operate.
- CRM fit, geographic coverage, and privacy requirements should shape the final choice. The right replacement is the one that fits your existing workflow and gives your team data they can actually use.

1. Ploy
Ploy takes a different approach from standalone enrichment tools. Instead of only sending data into other platforms, Ploy is built around your website. It can identify visitors, build pages, improve search performance, and help your team follow up with interested accounts.
Key features for B2B growth
Ploy Grow turns anonymous website traffic into identified companies through visitor de-anonymization. When someone visits your site, Ploy identifies the company, adds useful company details, looks at how they interact with your site, and sends qualified accounts to CRMs like HubSpot or Attio.
What you get:
- Lead prioritization: Ploy helps your team focus on companies showing real interest based on the pages they visit and how they use your site.
- Better outreach context: Sales teams can see what an account viewed before reaching out.
- Personalized landing pages: Ploy Web can create pages for specific target accounts.
- Slack alerts: Your team can get notified when high-value companies visit your site.
How it differs from Clearbit
Clearbit was mainly built for data enrichment. You provided an email address or domain, and it returned more information about that contact or company. Ploy starts with your website traffic, identifies visiting companies, and adds useful context before someone fills out a form.
Ideal fit
Ploy is a good fit for teams that want visitor identification, enrichment, personalized pages, and outreach tools in one place. It works especially well for companies that want to manage fewer separate tools.

Ploy helps your team identify visitors, build relevant pages, and follow up with better context.
2. ZoomInfo
ZoomInfo is built for large sales teams that need a lot of contact and company data. It gives teams access to business emails, phone numbers, job titles, company details, and signals that can help identify which accounts may be researching a purchase.
Key features
- Contact database: Find B2B contacts with email addresses, phone numbers, and job titles
- Company data: Research company size, industry, technology use, and team structure
- Buyer activity signals: See which companies may be researching topics related to your product
- Sales workflows: Send data into CRM and outreach tools and trigger follow-up actions
What to consider
ZoomInfo is generally built around annual contracts and takes time to set up properly. Teams may need to connect other tools, create workflows, and train users before they get full value from the platform. For smaller teams, that setup and management can be more than they need.
Ideal fit
ZoomInfo fits large sales organizations that need a broad contact database and have dedicated team members to manage setup, integrations, and day-to-day use.
3. Apollo.io
Apollo combines contact data and outreach tools in one platform. Teams can find prospects, get contact details, and start outreach without moving between several tools.
Key features
- Contact database: Find B2B contacts with email addresses and phone numbers
- Outreach sequences: Set up follow-up steps across email, calls, and LinkedIn
- Data enrichment: Add company and contact details to existing CRM records
- Chrome extension: Find contact information while browsing LinkedIn or company websites
What to consider
Data coverage can vary by industry and region. Before choosing Apollo, check how well it covers the types of companies and contacts your team usually targets.
Ideal fit

4. Cognism
Cognism is built for sales teams that care about data accuracy and privacy requirements, especially in European markets. It also offers phone-verified mobile numbers, which can be useful for teams that rely heavily on calling prospects.
Key features
- Diamond Data: Phone-verified mobile numbers
- Privacy-focused data practices: Processes designed around European data protection requirements
- Buyer activity signals: Uses Bombora data to help identify companies researching relevant topics
- CRM integrations: Connects with Salesforce, HubSpot, and Outreach
What to consider
Coverage can vary by region. Teams selling across multiple markets should check whether Cognism has enough data for the countries they target most.
Ideal fit
Cognism is a good fit for sales teams working in or selling to European markets that want verified contact data and a strong focus on privacy requirements.
5. Clay
Clay works differently from a traditional data provider. Instead of relying on one database, it connects to multiple data sources so teams can choose where each piece of contact or company information comes from.
Key features
- Multiple data sources: Connect to 50+ providers and use different sources for different records
- Custom workflows: Set up rules for how data is found, checked, and added
- AI research: Find extra information that may not be available from standard data providers
- Spreadsheet-style interface: Manage data in a familiar rows-and-columns format
What to consider
Clay gives teams a lot of flexibility, but setup takes time. You need to test different data sources and workflows to find what works best for your team.
Ideal fit
Clay is a good fit for operations teams that want more control over how they find and enrich contact data and are comfortable setting up custom workflows.
6. 6sense
6sense is built for large teams that use account-based marketing. It helps companies identify interested accounts, understand which businesses may be researching a purchase, and reach those accounts through marketing and advertising.
Key features
- Buyer activity signals: See which companies are researching topics related to your product
- Account prioritization: Use AI to identify accounts that may be closer to making a purchase
- Website visitor identification: Identify which companies are visiting your site
- Advertising: Run ads targeted at specific accounts
What to consider
6sense takes more time to set up than simpler tools. Teams need to connect their data, configure the platform, and build the workflows they want to use.
It also works best when marketing and sales are targeting the same accounts. Teams that still focus mainly on individual leads may not need everything the platform offers.
Ideal fit
6sense is a good fit for large marketing and sales teams running coordinated account-based campaigns and that have the resources to manage a more involved setup.
7. RB2B
RB2B helps sales teams identify individual website visitors, not just the companies they work for. That makes it useful for teams that want to know exactly who is showing interest in their product.
Key features
- Individual visitor identification: Identify specific visitors, not just their companies
- LinkedIn matching: Connect identified visitors with their LinkedIn profiles
- Slack alerts: Get notified when high-value visitors come to your site
- CRM integrations: Send identified visitors into your sales tools
What to consider
RB2B can give sales teams more specific visitor information, but individual identification usually covers fewer visitors than company-level identification.
Privacy note: Check that your use of visitor data follows the privacy rules that apply to your business and matches your privacy policy.
Ideal fit
RB2B is a good fit for sales teams that want to identify specific website visitors and follow up with them directly.
8. Lusha
Lusha gives sales teams a straightforward way to find business contact details. Its Chrome extension lets users look up email addresses and phone numbers while browsing LinkedIn or company websites. Teams can also connect Lusha data with other tools they already use.
Key features
- Contact database: Find B2B email addresses and phone numbers
- Chrome extension: Find contact details while browsing LinkedIn or company websites
- Data connections: Send Lusha data to other tools and workflows
- CRM updates: Add contact information to existing CRM records
What to consider
Data coverage can vary by industry, region, and type of contact. Teams targeting niche markets should check whether Lusha has enough data for the people and companies they typically target.
Ideal fit
Lusha is a good fit for sales teams that want a simple way to find contact information without a lengthy setup.
Why Ploy Stands Out
Most Clearbit alternatives force you to choose: get data, or act on it. Rarely both.
Ploy eliminates that choice. You get visitor identification, enrichment, CRM sync, personalized landing pages, and automated outreach in a single platform. When a target account visits your site, Ploy doesn’t just tell you who they are. It gives you the context, the tools, and the workflows to convert them.
You should choose Ploy if:
- You want to know which companies are on your site before they fill out a form
- You’re tired of stitching together visitor ID, enrichment, CRM, and personalization tools
- You need your website to work as a growth engine, not just a brochure
- You want automation that turns identified visitors into qualified meetings
For growth teams who want identification and action in one platform, Ploy delivers what Clearbit never did: the ability to see who’s interested and do something about it immediately.
Frequently Asked Questions
What happened to Clearbit after the HubSpot acquisition?
HubSpot acquired Clearbit and rebranded it as Breeze Intelligence, bringing its enrichment capabilities into HubSpot. Teams using Clearbit independently or with another CRM now need to move to HubSpot or choose another enrichment provider.
Can I replace Clearbit with a free tool?
Yes. Apollo offers free contact data access, while Ploy’s free tier includes visitor de-anonymization, CRM sync, and website capabilities with no credit card required. Higher enrichment volumes generally require a paid plan.
How long does it take to implement a Clearbit alternative?
Lightweight tools like Apollo, Lusha, and Ploy can get you running within days. Enterprise platforms like ZoomInfo and 6sense generally take longer because setup involves more data integration and workflow configuration.
What’s the difference between visitor identification and data enrichment?
Data enrichment adds information to contacts you already know, such as company size or job title. Visitor identification reveals which companies or people visit your website before they submit a form. Some platforms offer both, but they serve different workflows.
Which alternative works best for small teams?
Small teams benefit from tools that combine capabilities without heavy administration. Ploy brings visitor identification, website building, and growth workflows together, while Apollo combines contact data with outbound sequencing. Both offer a lighter setup than enterprise platforms.
