The Stripe record I pulled from an enrichment vendor looked perfect: 14 executives, 8,500 employees, a logo, and a Twitter handle. But that is a cherry-picked sample. Almost no vendor shows the actual fill rate across their entire database because they do not want you to see it.
This leaves buyers guessing who to believe. Zapier and Cognism list a few tools. HubSpot explains the concept. Apollo sells its own data. No one compares the marketing claims against what paying users actually get.
I wanted to find that gap. I took the top CRM enrichment vendors, recorded their claims, and then searched Reddit and G2 for the truth. When the vendor and the users disagree, I show you both.
What is CRM data enrichment?
CRM data enrichment is just filling the empty fields in your customer records with data from an outside source. You start with a company name and an email, and you end up with an industry, a headcount, a location, and a direct phone number.
It is necessary because CRMs rot. A sales manager on r/SalesOperations put it plainly: his team would import fresh contacts from Apollo or ZoomInfo, and within weeks the emails would bounce and the people would have moved. His team spent four hours a day just verifying contacts before they could even start selling.
That decay is why enrichment is never a one-time purchase. It is a subscription to a moving target, and the only question that matters is how much of that target a vendor actually hits.
What each vendor claims it fills
Here are the nine vendors that dominate the conversation, and what they claim about their data as of November 2026.
| Vendor | Their claim | Reality (users say) | Sources |
|---|---|---|---|
| Lusha | 515M+ verified B2B contacts, 165M+ verified emails, 98% email accuracy | Strong NA/EU SaaS email coverage per users; phone accuracy weaker at 86% globally | Lusha data page, r/sales_intelligence 4-vendor test |
| ZoomInfo | Millions of verified contacts, exceptional accuracy, no published pricing | Data depth respected; but buyers report $15k to $60k/yr contracts, seat fees, and auto-renewal with a 10% bump on 60 to 90 days notice | ZoomInfo, r/gtmengineering pricing thread, r/Sales_Professionals $30k/yr thread |
| Cognism | Phone-verified mobiles with additional manual and automated verification layers | EMEA mobile niche confirmed by users; US coverage reported weaker than the EMEA strength | Cognism, r/sales_intelligence 4-vendor test |
| Apollo.io | A customer quotes 72% to 94% email deliverability improvement; record selection limits per plan | Imports decay within weeks; users report 40 to 50% contact return, catch-all rejections, and data going stale fast | Apollo pricing, r/Coldemailing 40-50% report, r/SalesOperations decay thread |
| Clay | No coverage claim on its pricing page; positions as a waterfall across other providers | Cost surprises: $446/month to fill three columns reported; $800/month stack that delivered almost nothing until reconfigured | Clay pricing, r/gtmengineering $446 thread, r/CRM $800 stack thread |
| HubSpot Breeze (ex-Clearbit) | Enrichment bundled into Breeze Intelligence, credit-based on top of subscription | $45 entry with only 100 credits on top of a mandatory subscription; setups crossing $1,100/month reported post-acquisition | HubSpot, r/b2bmarketing $1,100/month thread |
| People Data Labs | 2,468,465,575 profiles, 592,188,754 with an email | Enormous coverage, but monthly batch refresh; users report staleness on anything time-sensitive | PDL datasets, r/B2BSales freshness report |
| RocketReach | Contact and direct-dial coverage, strongest for mobile numbers | Strong mobile and direct-dial niche per users; privacy opt-out complaints recur | RocketReach, r/sales_intelligence mobile thread, r/SaaS alternatives thread |
| NinjaPear | Measured, not claimed: 95.8% description, 88.0% headcount, 58.4% founded year, 34.3% work email | API-first, MCP-native; the only vendor on this list that publishes audited fill rates | nubela.co, 4,504,317 company and 74,256 person records, audited 2026-11-05 |
Notice what is missing. Only two rows contain a number a buyer can check. Lusha publishes an accuracy percentage but not the method behind it. PDL publishes record counts but not fill rates. No one publishes the number you actually need: if I hand you 100 records, how many come back filled?
I can answer that for one vendor because I work there. NinjaPear's description fills 4,313,872 of 4,504,317 company records, and every other field rate in the table above is measured the same way, against the full population, not a demo record.
What users say actually filled
The claims table is what vendors want you to think. This section is what their users actually report from r/CRM, r/SalesOperations, r/gtmengineering, r/hubspot, and r/sales_intelligence. I will tell you where they agree and where they do not.
Apollo.io
An SDR manager on r/SalesOperations said Apollo imports start failing within weeks, as emails bounce and titles go stale. In October 2026, a cold emailer on r/Coldemailing reported Apollo returning 40 to 50% of contacts, with some rejected by catch-all domains. The vendor's pricing page quotes a customer who saw deliverability move from 72% to 94%. The trend in user threads is clear: Apollo is the volume default and cheap per record, so the accuracy is exactly what you get for that price.
ZoomInfo
Users do not argue with the data depth, but they hate the bill. A r/gtmengineering thread from October 2026 listed pricing no official page will show you: Professional at around $15,000 a year for three seats, Advanced from $22,000 to $28,000, and most teams landing between $30,000 to $60,000 once seats and add-ons are in. There is also an auto-renewal with a 10% bump on 60 to 90 days notice. One user put it well: ZoomInfo is not just a contact provider in 2026, it is about the workflows, compliance, and direct dials. Both the data and the contract are true at once.
Clay
Clay does not make coverage claims because it is not a database. It orchestrates other providers and charges per enrichment. This leads to cost surprises. In October 2026, a r/gtmengineering poster paid $446 a month to fill three columns. A r/CRM thread from April 2026 described spending $800 a month across Clay, Apollo, and HubSpot and getting almost nothing until they fixed the configuration. Clay is powerful if the workflow is right and expensive if it is not.
HubSpot Breeze, formerly Clearbit
Clearbit was once standalone. Now it is bundled into Breeze Intelligence. This means a $45 entry point with 100 credits on top of a mandatory subscription, with some setups crossing $1,100 a month according to a r/b2bmarketing poster in November 2026. One user noted that per-lookup pricing beats a seat when you only enrich fifty accounts a month. The AI side is a different story. A r/hubspot thread titled Breeze is embarrassing, right? got 63 comments, and the top reply was simply: never use it. The data and the assistant are different products, and users grade them differently.
Cognism and Lusha
One r/sales_intelligence poster ran 500 accounts through Lusha, Apollo, ZoomInfo, and Cognism. The results were all over the place with almost no overlap on some mid-market companies. The most useful comment explained why: most providers use the same underlying sources, and only a few have proprietary collection. Because of this, provider A beats provider B depending on the segment and region. Some found Apollo plus Lusha beat ZoomInfo and Cognism on raw email coverage for SaaS in North America and Europe, while ZoomInfo won on org charts and phone. Premium tiers mostly just buy more usage, not more data.
People Data Labs and RocketReach
PDL has enormous coverage. Users agree with our own research: it refreshes monthly, which is fine for firmographics but expensive for anything time-sensitive. RocketReach appears most in threads about mobile numbers and direct dials. Users say it is one of the strongest options, though it shares the same complaint patterns as ZoomInfo on a smaller scale.
The one vendor users cannot grade yet
NinjaPear is mine, so discount this row like you would any vendor's. What I can tell you is what we measured: work emails for 34.3% of 74,256 person records, descriptions for 95.8% of 4.5 million companies. No other vendor in this table shows you its own database at this depth.
How to test any vendor on 100 records
You can test every vendor above the same way, and it costs almost nothing compared to a subscription. Pull 100 records from your own CRM, the messier the better. Run them through the vendor's endpoint. Then count three numbers: how many came back filled, how many came back empty, and how many came back wrong.
Here is the call in NinjaPear's API, using the same shape most vendors use:
curl -G "https://nubela.co/api/v2/company/details" \
--data-urlencode "website=https://stripe.com" \
-H "Authorization: Bearer YOUR_API_KEY"
A real response for Stripe returned a description, 8,500 employees, a founded year, an industry code, a logo, a Twitter handle, and a full address. That is one record. One record proves nothing, which is why you run a hundred.
The math is simple. If a vendor fills 40 of your 100 records and charges $0.50 a lookup, a filled record costs $1.25. If another vendor fills 70 and charges $0.10, a filled record costs $0.14. The headline price tells you nothing. The fill rate on your list tells you everything, and your list is the only denominator that matters.
What a filled record costs
Subscriptions and seat models hide the real cost. A ZoomInfo buyer paying $30,000 a year who enriches 10,000 records pays $3 a record regardless of whether the data is good. The money is gone either way.
The credit model is easier to calculate. NinjaPear charges 2 credits for a work email hit and 0.5 for a miss. On 1,000 lookups at our 34.3% hit rate, you spend 686.5 credits for 343 emails. That is about 2 credits per usable email. I work here, so test this with our free trial before you trust me. Then do the same for everyone else, because no other vendor will do this math with you.
A commenter on r/b2bmarketing had it right. Run twenty of your own contacts through a vendor and count the bounces. That number tells you more than the credit price ever will.
Which vendor fits which job?
There is no single winner. User reports show the best fit depends on the job.
| Your job | Best fit from the user reports | Why |
|---|---|---|
| Maximum contact volume, cheap | Apollo.io | The volume default; accuracy is the tradeoff users accept |
| US direct dials and org charts | ZoomInfo | Users agree the data is strong; the contract and price are the cost |
| Waterfall across many providers | Clay | The orchestration layer; watch the per-enrichment costs |
| Already on HubSpot | Breeze Intelligence | Least friction, bundled cost; verify the credit math first |
| EMEA phone-verified mobiles | Cognism | Its verification positioning matches its user niche |
| Email coverage in NA/EU SaaS | Lusha | Reported ahead of ZoomInfo and Cognism on that slice |
| Huge dataset, monthly refresh fine | People Data Labs | Coverage over freshness |
| Mobile numbers, smaller budget | RocketReach | The direct-dial niche at a lower price point |
| API-first product or agent build | NinjaPear | Our row; measured fill rates, MCP-native, per-credit pricing |
Do five things before you sign. Match the vendor to the job, not the review. Ask for the fill rate on your own list, not their whole database. Run the 100-record test. Read the auto-renewal clause, because the ZoomInfo thread is a warning. Finally, discount my row like you would any other, including the part where I gave you the unflattering numbers first.
