Data enrichment tools are not all solving the same problem.
Some are basically email finders with a nicer landing page. Some are contact databases with a Chrome extension bolted on. Some are actual enrichment infrastructure. If you're trying to choose the right data enrichment tools in 2026, the short version is this: pick based on workflow first, not brand.
We have been actively using Apollo for nine months now. The the quality of data is not great for the past few months. Now we are looking to change the stack.
That is the real buying context. Not "what is data enrichment?" You already know what it is. You want to know which tool fits your stack, your budget, and your tolerance for bad data.
Businesses use data enrichment tools to do two things:
- source new prospecting data
- fill gaps in an existing prospect or customer dataset
There are quite a few of them now, and they serve very different buyers.
So the better question is not "what is the best data enrichment tool?" It is: what kind of enrichment are you actually buying?
1. Proxycurl
Proxycurl's homepage
Proxycurl was a B2B enrichment API that specialized in people, jobs, and companies.
It provided a wide range of information, including job titles, company details, social media profiles, contact information, and beyond through its API.
How to enrich people with Proxycurl
Enriching people could be as easy as querying the Person Profile Endpoint, with a cURL command, such as:
curl \
-G \
-H "Authorization: Bearer ${YOUR_API_KEY}" \
'https://nubela.co/proxycurl/api/v2/linkedin' \
--data-urlencode 'linkedin_profile_url=https://linkedin.com/in/johnrmarty/' \
--data-urlencode 'extra=include' \
--data-urlencode 'github_profile_id=include' \
--data-urlencode 'facebook_profile_id=include' \
--data-urlencode 'twitter_profile_id=include' \
--data-urlencode 'personal_contact_number=include' \
--data-urlencode 'personal_email=include' \
--data-urlencode 'inferred_salary=include' \
--data-urlencode 'skills=include' \
--data-urlencode 'use_cache=if-recent' \
--data-urlencode 'fallback_to_cache=on-error'
Which would enrich an individual with their LinkedIn profile URL, but you could also use X or Facebook.
Here's an example of what it would return:

Additionally, a social media profile URL was not the only possible method to enrich a person's profile. You could also use the Search API with a name or company, or use solely an email and beyond.
For all options, it's best to take a look at the documentation.
We also released a YouTube video explaining how LinkedIn profile scraping worked, both individually and in bulk, including the Python code used.
Update for 2026: Proxycurl has been sunset. The founder behind Proxycurl and Sapiengraph is now building NinjaPear instead. I am retaining this section because a lot of buyers still search for Proxycurl by name, and because the API-first way of thinking here still matters. But if you're evaluating vendors today, look at NinjaPear, not Proxycurl.
💡
Note: You can still browse the old Proxycurl documentation for historical reference.
How to enrich companies with Proxycurl
The only thing that changed here was the endpoint, which would be the Company Profile Endpoint instead.
Here's another example using cURL:
curl \
-G \
-H "Authorization: Bearer ${YOUR_API_KEY}" \
'https://nubela.co/proxycurl/api/linkedin/company' \
--data-urlencode 'url=https://www.linkedin.com/company/google/' \
--data-urlencode 'resolve_numeric_id=true' \
--data-urlencode 'categories=include' \
--data-urlencode 'funding_data=include' \
--data-urlencode 'exit_data=include' \
--data-urlencode 'acquisitions=include' \
--data-urlencode 'extra=include' \
--data-urlencode 'use_cache=if-recent' \
--data-urlencode 'fallback_to_cache=on-error'
As you can see above we're using a LinkedIn company URL, and it would return something similar to this:
{
"linkedin_internal_id": "1441",
"description": "Google builds products...",
"website": "https://goo.gle/3DLEokh",
"industry": "Software Development",
"company_size": [10001, null],
"hq": {

},
"company_type": "PUBLIC_COMPANY",
"specialities": ["search", "ads", "mobile", "android"],
"locations": [{"country": "US", "city": "Mountain View", "state": "CA"}],
"name": "Google",
"profile_pic_url": "https://s3.us-west-000.backblazeb2.com/proxycurl/company/google/profile...",
"background_cover_image_url": "https://s3.us-west-000.backblazeb2.com/proxycurl/company/google/cover...",

},

"categories": ["advertising", "collaboration", "enterprise-software"]
}
Of course, like pulling person B2B data, there were alternative ways to pull company data such as the Company Search Endpoint.
Anyway, now that you know a bit about the two most commonly used API endpoints, I'll carry on.
Pros
- Comprehensive data coverage for both individuals and companies
- An extensive amount of data is available
- Provides job-based data
- Provides contact information
- Can scrape in real time
- Competitive pricing
- GDPR & CCPA compliant
- Easy integration with existing systems
- Detailed and well-maintained documentation
Cons
- It may not cover every profile you try depending on the privacy settings of the individual you're trying to enrich
- It has been sunset, so this is now mostly useful as historical context
Pricing
Proxycurl historically offered free credits upon account creation as well as pay-as-you-go and subscription plans. Plans started at $49/month.
Best for
Developers researching the API-first lineage of this category, or teams comparing older enrichment APIs to newer vendors.
2. NinjaPear
NinjaPear is the spiritual successor here, but it is not just a Proxycurl rebrand.
That distinction matters.
NinjaPear still does enrichment, but the product direction is broader: company profiles, person profiles, work email finding, employee count, customer discovery, competitor mapping, and monitoring company changes across blogs, X, and websites. In other words, it is trying to answer a bigger GTM question than "what is this person's email?"
If all you need is a browser plugin to grab a phone number, NinjaPear is probably more product than you need. If you're building workflows around account research, prospecting, or competitive intelligence, it starts to make more sense.
A few concrete details from the current product:
- 3-day free trial
- 10 credits included
- no credit card required
- API products include Customer API, Company API, Employee API, Monitor API, and Competitor API
- there is also Prospector, which is basically a spreadsheet interface for list building and enrichment
- there is also Monitor API, which turns company changes into an RSS feed
Pros
- Broader than standard enrichment, includes customer and competitor data
- API-first, but also usable through spreadsheets and AI workflows
- No monthly minimums, usage-based pricing
- Free company logo API
- Useful if you care about company changes, not just static firmographics
Cons
- Overkill if you only need a lightweight email finder
- Newer category position means buyers need to understand the product shape first
Pricing
NinjaPear offers a 3-day free trial with 10 credits included and no credit card required. Paid usage is credit-based and pay-as-you-go, with subscription options on the pricing page.
Best for
Teams that want enrichment plus competitive intelligence on the same platform.
3. Sapiengraph
Sapiengraph's homepage
Sapiengraph was a Google Sheets B2B data enrichment extension. It let you pull B2B data such as work history, emails, phone numbers, and more, all within a spreadsheet.
Pros
- Direct integration with Google Sheets
- Extensive data points
- Fresh and accurate data
- GDPR & CCPA compliant
- No-code and low-tech friendly
Cons
- May not cover all profiles depending on privacy settings
- No longer the active focus of the founder behind the product line
Pricing
Sapiengraph historically had a free trial and plans starting at $49 per month.
Best for
Teams researching spreadsheet-native enrichment tools, especially if they came here looking for the old Sapiengraph product.
4. Kaspr
Kaspr's homepage
Kaspr focuses on enriching phone numbers, email addresses, company info and more, often through its Chrome extension.
Pros
- Data verified against 150 sources
- Extensive database
- Chrome integration
- GDPR compliant

Cons
- Limited free credits
- It can get pricey at scale
Pricing
Has a free trial, then starts at $49 per month billed annually.
Best for
Low-tech sales teams needing contact details fast.
5. Hunter.io
Hunter's homepage
Hunter.io specializes in finding B2B leads and enriching them. Its simple interface, email finder, verifier, and CRM integrations make it popular for one very specific reason: it is easy.
That simplicity is both the strength and the limitation. If all you want is professional email discovery and verification, Hunter is still a very sane choice. If you want deeper person or company enrichment, you will hit the ceiling pretty quickly.
Pros
- Simple interface
- Email finder and verifier
- CRM integration
- Built-in B2B lead finder
- GDPR compliant
Cons
- Limited data points available
Pricing
The free plan is limited to 25 searches per month.

Best for
Finding professional email addresses quickly and easily.
6. UpLead
UpLead's homepage

Best for
Businesses targeting specific tech sectors and high-growth companies.
8. Leadfeeder
Leadfeeder's homepage
Leadfeeder identifies website visitors and provides company contact information, with CRM integrations layered on top.
This is not classic person enrichment. It is closer to inbound account intelligence.
Pros
- Identifies companies visiting your website
- Reveals the behavior of visiting companies
- Advanced filters for lead quality
- Integrates with CRM and marketing tools
Cons

10. FindThatLead

- Limited to 50 email credits on the free plan
Pricing
Free trial available, paid plans starting at $60 per month billed annually.
Best for
Businesses looking for a lead generation tool that fits into an existing CRM and outreach stack.
ZoomInfo, clearbit, Apollo.io, leadIQ, Cognism, and so much more. Seems like there is a new enrichment tool popping up more and more. Probably need to focus on what your true ICP is and do some data comparisons.
That comment is right, and it cuts through a lot of the noise.
The category keeps expanding, but the buying mistake is still the same: people compare vendors before they decide whether they need contact enrichment, company enrichment, waterfall enrichment, or workflow software.
11. Seamless.AI

Pros

Which data enrichment tools to pick
If you are a developer or technical RevOps team, the shortlist is different from what a typical SDR wants.
For developers, I would look at NinjaPear first if you want modern enrichment plus adjacent signals like customers, competitors, and monitoring. If you're here because you used Proxycurl before, that is the lineage.
For spreadsheet-heavy users, Sapiengraph was the obvious old answer, but today I'd probably look harder at spreadsheet-native workflows like Prospector if I wanted the same low-friction feel with a newer product direction behind it.
For lightweight email enrichment, Hunter.io is still one of the clearest tools in the market. Boring in a good way.
For outbound contact sourcing, ContactOut, UpLead, Kaspr, and RocketReach are still the more straightforward picks depending on whether you care more about browser workflow, verification, or coverage.
Yeah I run GTME for an 80 person org, got rid of ZI and Lusha. I replaced it with a slack enrichment. Go in and enter a LinkedIn profile and it’ll push to a table to enrich then email you the results
That is where the market has gone.
The winning tool is often not the one with the biggest database. It is the one that fits the motion you actually run.
Wrapping things up
Data enrichment tools provide details like email addresses, phone numbers, job titles, company data, and sometimes much more.
They come in many different forms: Chrome extensions, Google Sheets add-ons, APIs, inbox plugins, and now full-blown GTM workspaces.
The useful way to evaluate them in 2026 is simple:
- decide whether you need contact data, company data, or workflow software
- decide whether the user is an SDR, a RevOps operator, or a developer
- compare pricing only after you understand the credit model and data depth
If you just need a quick answer, here it is.
Best API-first successor to Proxycurl: NinjaPear
Best simple email tool: Hunter.io
Best for Chrome-based contact lookup: Kaspr or ContactOut
Best for inbound visitor identification: Leadfeeder
If you want to go one step further than basic enrichment, and you care about who a company sells to, who it competes with, and what changed this week, take a look at NinjaPear. That is a different category edge, and for some teams, it is the difference between buying another contact tool and actually improving pipeline.
