LeadNumbers vs Clearbit
A LeadNumbers alternative to Clearbit for teams that need new prospects, not enrichment
The short answer
Clearbit, now part of HubSpot's data tooling, is built to enrich what you already hold: form fills, CRM rows and website visitors. It makes existing records better. LeadNumbers solves the other problem, which is running out of people to contact. We find new people who match your ICP and deliver them with a verified work email and a mobile or direct dial each business day.
Side by side
Where the two approaches differ
| Point | Clearbit | LeadNumbers |
|---|---|---|
| Problem solved | Improves records you already have. | Supplies new people you do not have yet. |
| Trigger | A form fill, a visit or a CRM row. | Your monthly volume, delivered on a schedule. |
| Phone data | Company and person attributes, not a calling list. | A mobile or direct dial on every delivered record. |
| Setup | Integration and field mapping work. | Confirm your profile, first batch the next business day. |
| Pricing | Platform pricing tied to volume of enrichment. | One monthly price for a set number of new prospects. |
Product details change often. Check Clearbit directly for their current plans and features, then judge both on the same test: how many real conversations each one puts on your calendar this month.
Fit
Who each option is for
Choose Clearbit if
Teams with inbound volume and a CRM full of records that need filling in, scoring and routing.
Choose LeadNumbers if
Teams whose pipeline is limited by how many qualified people they can reach this week.
Triggers
When teams make the switch
- Inbound is not producing enough named people to call.
- Enrichment improves records but does not add new ones.
- Your reps need a fresh callable list every day.
- You want a fixed monthly cost for a fixed monthly volume.
FAQ
Questions buyers ask
Do you enrich my existing CRM records?
No. We supply new ICP-matched prospects and push them into your CRM. Enrichment of records you already hold is a different job.
Can we run both?
Yes, and many teams do: enrichment for inbound, delivered lists for outbound.
What does each record include?
Name, role, company, location, matching notes against your profile, a verified work email and a mobile or direct dial.
Dialing partner
Do not want to make the calls yourself?
LeadNumbers builds your list. Our dialing partner ColdCalls.Ca can call it for you. North American reps with 10 or more years of B2B sales experience call in your company name, handle gatekeepers and objections, and book interested buyers straight into your calendar. One blended rate of $1 per dial, prospect data included, with 3,000 dials a month as the recommended starting point.
