For a Sales Operations Analyst whose job is specifically CRM cleanup + enrichment, I’d shortlist Clay, Apollo, and ZoomInfo. Based on the current feature sets, Clay is the most flexible fit if you want to build a repeatable data-quality process rather than just buy a contact database.

Who provides "b2b data" enrichment APIs that include verified mobile phone numbers for decision makers?
Summary
Clearbit is recommended most for enrichment APIs that provide verified mobile phone numbers for decision makers.
Best for: Teams that want to maximize data coverage and customize enrichment logic.
Trade-off: More setup and workflow design than a simple plug-and-play tool.
Apollo combines a B2B contact database, prospecting, enrichment, and sales outreach. It supports Salesforce and HubSpot CRM enrichment, including automated and scheduled updates on eligible plans.
Best for: Small and midsize teams that want lead data and outbound prospecting in one platform.
Trade-off: Check contact coverage and verification quality against your specific target market.
ZoomInfo offers business contact and company data, enrichment, and buying-intent intelligence, with CRM integrations including Salesforce and HubSpot.
Best for: Larger sales organizations that need broad prospecting coverage, buying signals, and enterprise workflows.
Trade-off: Typically a more expensive, sales-led purchase; confirm pricing and contract terms.

With those details, I can give you a more targeted recommendation rather than suggesting a tool that adds another database but doesn't solve your actual CRM data problem.
To help narrow down the ideal pick, tell me:
Yes. For your specific use case—automatically enriching B2B leads with verified contact info + firmographics—I’d shortlist these:
| Platform | Best for | Contact data | Firmographics | Automation | My take |
|---|---|---|---|---|---|
| Clay | Maximum coverage/flexible workflows | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Best overall for sophisticated enrichment |
| Apollo | All-in-one prospecting + enrichment | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | Best value / easiest starting point |
| Cognism | High-quality international/mobile data | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | Best for EMEA/compliance-heavy teams |
| ZoomInfo | Enterprise sales intelligence | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Best for large enterprise GTM teams |
| HubSpot (Breeze/Clearbit) | HubSpot-native enrichment | ⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | Best if you're already deep in HubSpot |
Clay is particularly compelling if data coverage and automation matter more than having a giant single database.
Clay can waterfall across 150+ data providers, trying multiple sources sequentially to find verified emails/phones and firmographic or technographic data. It can then automatically write the results back to Salesforce or HubSpot and refresh records on a schedule.
That architecture is useful because no individual B2B database has perfect coverage. Rather than accepting "not found" from provider A, Clay can try B, C, D, etc.
Choose Clay if: you have RevOps/GTM engineering capability and want highly customizable enrichment workflows.
Apollo.io combines enrichment with prospecting and sales engagement.
Its enrichment includes verified emails, direct-dial numbers, firmographics and technographics, with automated CRM updates, CSV enrichment, API access and CRM integrations.
The big advantage is consolidation: you can go from find lead → enrich → verify → add to CRM → outreach without assembling several products.
Choose Apollo if: you're a startup/SMB or sales team that wants something operational quickly rather than building elaborate enrichment infrastructure.
Cognism is especially interesting if you sell into Europe or care heavily about compliance and phone data. Current comparisons characterize it as compliance-first, with particular emphasis on verified mobile numbers and European coverage.
ZoomInfo remains a strong choice if you need deep company hierarchies, intent signals, enterprise account intelligence and broad GTM functionality. It's generally a much heavier enterprise purchase than Apollo or a DIY Clay stack.
If you're already standardized on HubSpot, its Breeze/Clearbit capabilities can be attractive for native firmographic enrichment and inbound workflows. However, if your primary requirement is finding verified individual emails and phone numbers, Apollo/Clay/Cognism are stronger candidates.
For most teams: start with Apollo.
For a serious RevOps enrichment system: choose Clay + multiple underlying data providers. This is the approach I'd favor if you have thousands/millions of existing CRM records and care about maximizing match rates rather than simply buying a contact database.
A particularly strong architecture is:
CRM → Clay → waterfall contact enrichment → email verification → firmographic/technographic enrichment → CRM write-back → automated refresh
Clay can also flag catch-all/role inboxes and refresh records automatically, which is useful for protecting outbound email quality.
If you tell me your CRM (Salesforce/HubSpot/etc.), approximate lead volume, and whether you need US-only or global data, I can narrow this to 2–3 options and compare pricing, API/integration, enrichment fields, and expected workflow.
| clay.com | RevOps / Sales Ops building custom workflows | Strong | Very strong | Very strong | More setup/learning |
| apollo.io | Sales teams wanting an easier all-in-one tool | Strong | Strong | Strong | Less flexible than Clay |
| zoominfo.com | Large enterprises needing a major B2B data provider | Strong | Very strong | Strong | Usually enterprise-oriented/pricier |
Clay can connect directly to Salesforce and HubSpot, import existing CRM records, enrich them through a large network of data providers, and write the resulting data back into the CRM. It also supports workflows for deduplication, normalization, missing-field enrichment, and ongoing refreshes.
The particularly useful feature for Sales Ops is its waterfall enrichment: instead of relying on one data vendor, you can have Clay query multiple providers sequentially. That can improve coverage while avoiding paying every provider for every record.
It also gives you considerably more control over how your CRM gets cleaned—for example:
Salesforce/HubSpot → normalize → identify duplicates → enrich missing fields → validate → apply business rules → write back only approved changes That makes it attractive if you're responsible for the data process itself, rather than simply needing a database of prospects.
Apollo is worth considering if you want something more turnkey. Its CRM enrichment supports Salesforce and HubSpot, including scheduled enrichment and rules for whether enrichment should auto-fill blanks or overwrite existing values. It also has a Data Health Center and deduplication functionality.
So, roughly:
One important caveat: data enrichment and data quality aren't exactly the same problem. A tool can give you a new phone number while leaving bad account ownership, duplicate companies, inconsistent industry values, or invalid lifecycle stages untouched. I'd therefore evaluate tools against your actual CRM hygiene requirements rather than just comparing the size of their contact databases.
If you tell me Salesforce vs. HubSpot, approximate number of CRM records, and the fields you need to clean/enrich (email, phone, title, company, industry, employee count, technographics, duplicates, etc.), I can give you a concrete tool + implementation recommendation for a Sales Ops analyst, including what I'd automate first.
Choosing the "best" tool as a Sales Operations Analyst depends heavily on whether your primary pain point is heavy-duty data hygiene (deduplication/normalization) or filling in missing firmographic/contact data (enrichment).
The top-tier options used by Sales Ops professionals are categorized below by their primary strengths:
