Clearbit vs 6sense vs Demandbase: ABM and Intent Data Platform Comparison
On this page
Compare enrichment and account workflows separately
Clearbit, 6sense and Demandbase are relevant to B2B enrichment and account-based sales or marketing. Their public pages do not establish a common accuracy benchmark, and a sales-data package should not be priced as if it were a complete marketing platform.
Official pages were checked on 8 October 2026. This is a documentation review, not a hands-on performance test. Historic annual-cost ranges and unsupported accuracy rankings have been removed.
What the official pages establish
| Product | Documented scope | Purchasing question |
|---|---|---|
| Clearbit | Its site states that it has joined HubSpot and describes record enrichment, lead scoring/routing, visitor company identification and form shortening. | Which capabilities are available in your current HubSpot or existing Clearbit agreement? |
| 6sense | The Sales Intelligence pricing page offers a free entry route and describes sales features such as company/people search and list building. | Is your quote for sales intelligence, marketing capabilities, or both? |
| Demandbase | Its pricing page describes a Sales and Marketing platform, advertising as a starting option, and data solutions available separately. | Which modules, users, data and services are included? |

Demandbase documents a platform fee plus a per-user fee for Sales and Marketing and asks buyers to request a customized plan. That does not support a universal annual starting price. Clearbit's homepage does not establish a current standalone free tier or a universal monthly price. Obtain a written quote for the product and capabilities you will actually use.
A useful evaluation plan
Use the same permitted account sample and required fields for each evaluation. Keep the input records so you can compare matched company, person, business email, source date and unmatched records. Separate these checks:
- Enrichment: whether required fields are returned and whether they are correct for the source record.
- Account identification: whether a signal refers to the correct company; it does not prove the identity of an individual visitor.
- Intent: whether the signal helps your own qualification process, using recorded outcomes and dates.
- Operations: whether permissions, integrations, exports and deletion requests fit your team.
- Cost: seats, modules, data allowances, implementation, renewal and any advertising spend.
A vendor's database size, customer story or advertised success rate does not prove that it will outperform another product on your sample. Ask for the methodology behind any claimed accuracy rate.
Extracting an address inventory
First confirm that your contract and account permissions allow the export you need. Export email fields together with provider status, record IDs and other context; export entitlements for every product were not verified in this review.
Upload a copy of a supported CSV, spreadsheet or JSON export to Email Extractor for a list of email strings. CSV with sources shows overlap between exports. Keep original records for company/person matching, verification and suppression decisions. Extraction does not reproduce intent scores, enrichment relationships or marketing consent.
