TL;DR: Clay is the most flexible enrichment platform with waterfall across 75+ providers and a 14-day trial. Apollo covers 275M contacts and bundles outbound automation. Kaspr leads on LinkedIn-sourced phone numbers with a permanent free plan. For most seed-stage founders enriching trial signups or building outbound lists, Clay or Apollo are the right starting points.

Best CRM Enrichment Tools With a Free Trial in 2026

Last updated: May 2026

The top crm enrichment free trial are Clay (Waterfall enrichment across 75+ data providers. 14-day free trial. Best for teams that need maximum data coverage and want to run enrichment inside a workflow builder., $149/month (Starter) to $800/month (Pro); free trial for 14 days), Apollo (Database of 275M contacts with built-in outbound automation. 14-day free trial of paid features. Best for teams that want enrichment and sequencing in one tool., $59/month (Basic) to $149/month (Organization); 14-day trial), Kaspr (500M+ verified phone numbers and emails, sourced primarily via LinkedIn. Permanent free plan available. Best for SDRs doing high-volume LinkedIn prospecting., $59/month (Starter) to $99/month (Organization); free plan available), Adapt.io (250M contacts across 50+ data types including firmographic and technographic. Free trial on paid plans. Best for teams that need broad data type coverage., $49/month (Starter) to $99/month (Basic); free trial on paid tiers), ZoomInfo (Enterprise-grade B2B intelligence pulling from 60+ data vendors. Trial available by request. Best for mature GTM teams with larger budgets and complex enrichment workflows., Custom (pricing by request); free trial available on request), Crunchbase (Company intelligence and investment data for account-level enrichment. 7-day trial on Pro plan. Best for teams doing account-based prospecting in the startup and VC ecosystem., $99/month (Pro); 7-day free trial (Pro plan only, enrichment not included)).

Free trials have become the standard entry point for evaluating B2B data tools. But not all trials are equal. Some let you test the full product for 14 days. Others lock enrichment behind a paywall and offer a trial of a limited free tier. In 2026, six tools dominate the CRM enrichment category with meaningful trial options: Clay, Apollo, Kaspr, Adapt.io, ZoomInfo, and Crunchbase. Each has a different data strength, a different integration story, and a different definition of what 'free' actually means.

What to Look For in a CRM Enrichment Tool Before You Start a Free Trial

Two criteria matter more than anything else: data coverage and CRM integration.

Data coverage tells you what percentage of your records the tool can actually enrich. A tool with a database of 250M contacts sounds impressive until you run 500 startup founders through it and get matches on 60%. The best tools use waterfall enrichment, checking multiple data providers in sequence so a miss on one source doesn't mean a permanent gap.

CRM integration tells you whether enriched data lands automatically in HubSpot or Salesforce, or whether you're exporting CSVs and importing them manually. The manual path kills the workflow before it starts.

Beyond those two: pay attention to what the free trial actually includes. Several tools on this list gate their most useful data types behind paid plans, then offer a 'free trial' of the full product only at the paid tier. If you need technographic data or email verification, check whether that's in the trial or held back. The goal is to test the feature you plan to use daily, not a stripped-down version of it.

Clay: Waterfall Enrichment Across 75+ Data Providers

Clay is the most flexible CRM enrichment platform available for B2B teams in 2026. Where most enrichment tools check one data provider and return whatever they find, Clay uses waterfall enrichment: it queries multiple data providers in sequence, using the next source only when the previous one misses. The result is 2-3x better coverage compared to single-source tools, according to Clay's own benchmarks.

The waterfall runs across 75+ data providers natively integrated into Clay's platform. You're not managing separate subscriptions to Apollo, Clearbit, Hunter, and Kaspr. Clay aggregates them into one enrichment layer. For a contact record that's missing a work email, Clay might check five providers before finding a valid match or declaring a gap. For firmographic data like company size or tech stack, the same logic applies.

On the CRM side, Clay has native integrations with HubSpot, Salesforce, Close, Pipedrive, and other major platforms. Enriched data flows directly into your CRM fields without manual export-and-import cycles. You can also trigger enrichment workflows based on CRM events. a new lead created in HubSpot, a deal reaching a certain stage, or a weekly scheduled refresh of stale contact records.

What Clay can enrich:

• Work email addresses and phone numbers
• Job title and seniority level
• Company name, size, industry, and tech stack
• LinkedIn profile URLs
• Firmographic data (employee count, revenue, funding stage)
• Technographic data (which tools a company uses)

Free trial and pricing: Clay offers a 14-day free trial of the full product, which is one of the most generous in the category. You get access to the waterfall enrichment, all integrations, and workflow templates. There's also a free-forever plan with limited credits if you want to test the interface without committing to a trial timeline.

Paid plans start at $149/month for the Starter tier, $349/month for Explorer, $800/month for Pro, and custom pricing for Enterprise. Credits are the unit of consumption. each data provider query spends credits.

Clay's template library: Clay ships with pre-built workflow templates that cover common enrichment jobs:

• Finding a work email from a name and company domain
• Updating HubSpot contacts with job title, LinkedIn URL, and company details
• Enriching any URL to return contact name, email, company, company size, and more

For teams enriching free trial signups, the URL enrichment template is particularly useful: when someone signs up with their work email, Clay can resolve the company domain, pull firmographic data, match the person's profile, and push a fully enriched record to your CRM in seconds.

When to choose Clay: Clay is the right tool when data coverage is your top priority, when you want enrichment to run inside a broader workflow (not as a standalone step), or when you're already using Apollo and want to add Clay's waterfall layer on top. Clay integrates with Apollo directly, so you can access Apollo's database as one of Clay's 75+ providers.

For deeper benchmarks and pricing details, see the full Clay Pricing 2026 guide and Clay Review.

Apollo.io: 275 Million Contacts Plus Outbound Automation

Apollo.io is the closest competitor to Clay in the enrichment category, but with a meaningfully different product philosophy. Where Clay is a workflow builder built around enrichment, Apollo is an outbound platform with enrichment built in. That distinction matters when you're choosing between them.

Apollo's database covers 275 million contacts and 73 million companies. For most B2B segments, that breadth means high match rates when you run your CRM records through enrichment. Apollo enriches standard contact fields. email, phone, job title, company, LinkedIn. and adds buyer intent data that tells you which contacts are actively researching products in your category.

What Apollo can enrich:

• Email addresses (work and personal)
• Direct dial and mobile phone numbers
• Job title, seniority, and department
• Company name, size, revenue, and industry
• Buyer intent signals (which categories a company is researching)
• LinkedIn profiles and social handles

Enrichment can run in real time (when a new contact enters your CRM) or on a schedule (nightly refresh of your full database). Apollo handles both modes natively.

The free trial situation: Apollo has a free plan, but it's important to understand what the free plan excludes. CRM data enrichment is a paid feature. the free plan gives you access to Apollo's prospecting tools but not to the enrichment workflow. To test enrichment, you need the 14-day free trial of a paid tier.

Paid plans:

• Basic: $59/month
• Professional: $99/month
• Organization: $149/month

The 14-day trial covers the full feature set of whichever tier you start on, including enrichment, sequencing, and the intent data layer.

Apollo's outbound automation: What sets Apollo apart from enrichment-only tools is the built-in sequencer. After enriching a batch of contacts, you can build a cold email sequence directly in Apollo, assign contacts to it, and launch. without switching to a separate tool like Instantly or Smartlead. The conversation intelligence feature records and analyzes sales calls, feeding insights back into your CRM.

For startups that want enrichment and outbound in one platform without stitching multiple tools together, Apollo is a strong default choice.

When to choose Apollo over Clay:

• You want enrichment and sequencing in one tool, managed in one interface
• You're building outbound from scratch and don't want to evaluate multiple platforms
• You primarily need contact-level data (emails, phones) rather than heavy firmographic or technographic coverage

When to choose Clay over Apollo:

• You need maximum data coverage via waterfall and are willing to manage a more complex workflow setup
• You already have a sequencing tool you like (Instantly, Smartlead, Outreach) and want top enrichment separately
• You want to run enrichment on more complex logic (e.g., enriching only contacts that match certain ICP criteria before updating your CRM)

For a full side-by-side, see Clay vs Apollo 2026. For Apollo's pricing breakdown, Apollo Pricing 2026 covers the credit system in detail.

Kaspr: LinkedIn-Sourced Phone Numbers and Email Addresses

Kaspr takes a narrower approach than Clay or Apollo. It's purpose-built for LinkedIn prospecting: finding phone numbers and email addresses for contacts you discover on LinkedIn, Sales Navigator, or Recruiter Lite. That focus produces a database of 500M+ verified phone numbers and email addresses, with GDPR and CCPA-aligned data sourcing.

Kaspr offers two enrichment methods:

1. LinkedIn Chrome extension: Install the extension, browse LinkedIn profiles or lists, and Kaspr surfaces contact details inline. It works on standard LinkedIn, Sales Navigator, and Recruiter Lite.

2. Kaspr API: Submit a list of LinkedIn IDs and get back contact data in bulk. This is the integration path for teams that want to automate enrichment without manual browser interactions.

What Kaspr can enrich:

• Work email addresses
• Direct phone numbers (mobile and landline)
• LinkedIn profile data
• Basic company information

Kaspr is strong on contact-level data. particularly phone numbers, where it has among the largest verified databases in the market. but it's not the right tool if you need firmographic depth, technographic data, or enrichment across contact sources beyond LinkedIn.

The free plan: Kaspr offers a permanent free plan, which is unusual in this category. The free plan includes CRM integrations but limits you to the LinkedIn Chrome extension only. You can't access the Kaspr API or use the extension with Sales Navigator or Recruiter Lite on the free plan.

For SDRs doing prospecting manually on LinkedIn, the free plan is genuinely usable. For teams that want to automate enrichment at volume, a paid plan is required.

Paid plans:

• Starter: $59/month
• Business: $99/month
• Organization: $99/month

When to choose Kaspr:

• You're prospecting primarily through LinkedIn
• You need phone numbers more than email addresses
• You want a free plan that actually covers your workflow (manual LinkedIn prospecting)
• You don't need technographic or firmographic depth

If your enrichment needs extend beyond LinkedIn-sourced contacts, pair Kaspr with Clay or Apollo. Kaspr covers the LinkedIn layer; Clay or Apollo fill in everything else.

Adapt.io: 50+ Data Types Across 250 Million Contacts

Adapt.io differentiates on data type breadth. While most enrichment tools focus on contact-level fields (email, phone, job title), Adapt.io covers 50+ data types across three dimensions:

1. Demographic data: Contact name, job title, seniority, department, LinkedIn URL, email, phone
2. Firmographic data: Company name, industry, employee count, revenue, location, founding year
3. Technographic data: Which software tools a company uses, including CRM, marketing automation, and sales tools

That technographic layer is where Adapt.io stands out. If you want to target companies that use Salesforce but not HubSpot, or companies running Shopify rather than Magento, Adapt.io can filter on those signals.

The contact database covers 250 million records. Adapt.io connects directly to Salesforce, HubSpot, Pipedrive, Zoho, Outreach, and Salesgear for CRM enrichment. You can also enrich CSV files or use the Adapt.io API to enrich any system or database.

The trial situation: Adapt.io's free plan includes 25 credits, which is enough for a basic test but not a meaningful evaluation. CRM export capabilities are locked to paid plans. To properly test Adapt.io with your CRM workflow, you need the paid trial.

Free trial availability:

• Starter ($49/month): No trial
• Basic ($99/month): Free trial included
• Custom (pricing on request): Free trial included

The trial on Basic and Custom gives you access to CRM exports and the full data type catalog.

When to choose Adapt.io:

• You need technographic data as a prospecting filter
• You want to enrich across all three dimensions (demographic, firmographic, technographic) from one provider
• You're connecting to a less common CRM like Zoho or Salesgear

When Adapt.io isn't the right fit: Adapt.io's database at 250M contacts is competitive but smaller than Apollo's 275M. For pure contact-level enrichment (email and phone only), Clay or Apollo will typically have better coverage. Adapt.io earns its place when the technographic dimension is part of your ICP criteria.

ZoomInfo: Enterprise-Grade Data With Workflow Automation

ZoomInfo is the enterprise incumbent in B2B data intelligence. It aggregates contact and company data from 60+ vendors, which produces broad coverage and frequent data refreshes. For large GTM teams at Series B and beyond, ZoomInfo is a common choice. For seed-stage startups, it's usually the wrong tool.

What ZoomInfo enriches:

• Email addresses and direct dial numbers
• Job title, seniority, and department
• Company details: size, revenue, industry, location, tech stack
• Buyer intent data (which companies are researching your category)
• Database health metrics: deduplication, normalization, and segmentation before enrichment runs

The pre-enrichment data cleansing is one of ZoomInfo's differentiators. Before your CRM receives enriched data, ZoomInfo deduplicates and normalizes your existing records. That means you're not enriching duplicates or writing enriched data onto inconsistent field formats.

ZoomInfo connects to HubSpot, Salesloft, and Salesforce natively. For any other system, the ZoomInfo API is the integration path. Real-time enrichment and scheduled enrichment are both supported.

The trial process: ZoomInfo's free trial requires a conversation with their sales team. They don't publish trial terms publicly, and the trial is initiated through a sales-qualified demo request. This is not unusual for enterprise software, but it means you can't self-serve a trial the way you can with Clay, Apollo, or Kaspr.

Pricing is also not published. It's negotiated based on seat count, database size, and feature tier.

Honest assessment: ZoomInfo is strong on data quality and has enterprise workflow features that smaller tools don't. But the sales-mediated trial process, undisclosed pricing, and general overhead of the platform make it a poor fit for most early-stage teams. If you're a Series B company with a RevOps team that manages CRM data professionally, ZoomInfo is worth evaluating. If you're a seed-stage founder trying to enrich a list of 500 trial signups, start with Clay or Apollo. you'll get a decision faster and at lower cost.

For a direct comparison, see Apollo vs ZoomInfo 2026.

Crunchbase: Company Intelligence for Account-Based Enrichment

Crunchbase occupies a different part of the enrichment landscape. It's a company intelligence platform, not a contact enrichment tool. That distinction matters for how you use it.

Crunchbase tracks funding rounds, investors, founding teams, employee headcount, and corporate structure. It has rich data on private companies, startups, and VC-backed organizations that aren't well-covered by traditional B2B databases. If you're prospecting into the startup ecosystem or targeting companies by their funding stage (Series A, Series B, recently funded), Crunchbase gives you signal that Clay or Apollo may lack.

What Crunchbase enriches:

• Company name, description, and website
• Funding history (rounds, amounts, investors)
• Company size and employee count
• Founding date and key executives
• Industry classification and keywords
• Technology stack (limited)

CRM integrations: Crunchbase connects to Monday CRM, HubSpot, and Salesforce directly. The API handles enrichment for any other system. CSV upload and bulk export are also supported.

The trial situation: Crunchbase's 7-day free trial is the most limited of the six tools covered here. The trial applies to the Pro plan ($99/month) but CRM enrichment is not included in the trial. Enterprise plan trials require contacting customer support.

In practice: the Crunchbase trial lets you evaluate their company search and market research features, but not the enrichment workflow you'd actually use day-to-day. Plan for a paid subscription if you want to test CRM enrichment.

When to choose Crunchbase:

• You're doing account-based prospecting into the startup and VC ecosystem
• You need investment signal as a trigger (e.g., target companies that raised a Series A in the last 90 days)
• You're in financial services, consulting, or recruiting and need rich company intelligence
• You're pairing it with Clay or Apollo for contact-level data (emails, phone numbers)

When Crunchbase isn't the right tool: For contact-level enrichment. finding email addresses and phone numbers for specific people. Crunchbase is weak. It doesn't have a meaningful contact database the way Apollo or Kaspr do. Use Crunchbase for account identification and company intelligence, then hand off to Clay or Apollo to get actual contact data.

Side-by-Side: What Each Free Trial Actually Covers

The most important thing to know before starting any of these trials is whether the trial includes the specific feature you need to evaluate. Here's an honest comparison:

Key takeaways:

Clay and Apollo give you the best pre-commitment testing window. Both offer 14-day trials of the actual enrichment features, and Apollo's $59/month entry point is the lowest of any full-featured paid tier. If you're evaluating tools for the first time, start with one of these two.

Kaspr's permanent free plan is genuinely useful if your enrichment need is specifically contact data from LinkedIn. You don't need to commit to a trial timeline.

Adapt.io's free plan is too limited to evaluate properly. you need the Basic tier trial to test the CRM workflow, which means engaging with their sales process first.

ZoomInfo and Crunchbase have the most friction to access trial features. ZoomInfo requires a sales conversation; Crunchbase's 7-day trial doesn't include enrichment. Factor that friction into your evaluation timeline.

For teams at the seed stage making their first enrichment tool decision: Clay and Apollo offer the best combination of trial depth, pricing clarity, and self-serve access.

How Miniloop Handles CRM Enrichment Workflows

Clay, Apollo, Kaspr, Adapt.io, ZoomInfo, and Crunchbase handle data sourcing. They find the information and put it in a field. But enrichment involves more than that. The busywork sits in the surrounding workflow: setting up the enrichment trigger, configuring waterfall sequences, refreshing stale records on a schedule, scoring enriched contacts against your ICP criteria, routing qualified contacts to outbound sequences, and monitoring when enrichment fails because a provider returned a miss.

That's the part that takes time. whether you're doing it yourself, you have a RevOps hire, or you've brought in a GTM engineer.

Miniloop handles that busywork. We build and run enrichment-connected workflows for your team:

• Enrichment on new signups: When someone signs up for your trial, we pull the enrichment automatically. work email to company domain, domain to firmographic record, contact to LinkedIn profile. and push a complete record to your CRM before your first onboarding email sends.
• Scheduled CRM refresh jobs: Stale CRM data is a constant problem. We run weekly or daily enrichment jobs that update job titles, company sizes, and tech stacks on your existing contacts so your database stays current without manual maintenance.
• ICP scoring on enriched records: After enrichment, we score each contact against your ICP criteria (company size, funding stage, tech stack, seniority) and route high-fit contacts to priority lists in HubSpot or Salesforce.
• Outbound trigger workflows: When an enriched contact crosses your ICP threshold, we push them to your sequencer (Instantly, Smartlead, Outreach, or Salesloft) and start the sequence automatically. no manual CSV export, no spreadsheet handoff.
• Enrichment gap alerts: When a contact can't be enriched (no match across providers), we surface the gap in Slack so your team knows where manual research is needed.

Whether you have a RevOps team, a solo GTM hire, or you're doing it yourself, Miniloop handles the execution layer between your enrichment tool and your CRM and sequencer.

Which CRM Enrichment Tool Should You Start With?

The right tool depends on what you're enriching and what you'll do with the data after.

For maximum data coverage: Start with Clay. The 14-day trial is generous, the waterfall approach means fewer gaps in your data, and the workflow builder means enrichment can connect directly to your CRM and sequencer without manual steps. How to Build a Lead Enrichment Workflow in Clay walks through the setup.

For enrichment and outbound in one tool: Start with Apollo. If you're going to sequence from the same list you just enriched, keeping both in Apollo is simpler than managing Clay for enrichment and a separate sequencer for outbound. Apollo's $59/month entry point is also the lowest floor in the category.

For LinkedIn-heavy prospecting: Start with Kaspr's free plan. If your prospecting workflow is manual LinkedIn browsing rather than CRM automation, Kaspr's Chrome extension covers the core need without a paid commitment. Upgrade when you need the API.

For account-based prospecting into startups: Crunchbase for company intelligence, paired with Clay or Apollo for contact data. Crunchbase tells you which accounts to target; Clay or Apollo find the people inside those accounts.

For enterprise teams: ZoomInfo is worth evaluating at Series B and beyond, when you have a RevOps team managing CRM data hygiene. For earlier stages, the sales-mediated trial process and undisclosed pricing add friction that Clay and Apollo don't.

The honest answer for most B2B founders reading this: start with Clay's 14-day trial or Apollo's 14-day trial. Both are self-serve, both include the actual enrichment features, and both have clear pricing before you commit. Run your first 200 trial signups or outbound prospects through whichever one you pick. That's enough data to know whether the coverage justifies the subscription.

For more context on the broader outbound stack, Sales Prospecting Best Practices and B2B Contact Information cover the research and verification layer that comes before and after enrichment.
