HubSpot-native CRM enrichment vs. full ABM platform — different categories, different price tags.
Clearbit and 6sense are often listed in the same category — 'data and intent' — but they are not comparable products. Clearbit, now rebranded as Breeze Intelligence after HubSpot's acquisition, is a CRM enrichment tool: it takes your existing HubSpot records and appends 85+ data points (firmographics, tech stack, funding, headcount) in real time. 6sense is a full account-based marketing platform — it identifies anonymous buyers visiting your site, predicts which accounts are in-market using AI models, surfaces buying stage signals, and activates advertising to those accounts before they ever fill out a form. One keeps your CRM clean and complete. The other runs a multi-channel demand generation motion.
CRM enrichment vs. intent-driven ABM
Clearbit/Breeze Intelligence is fundamentally about data completeness. When a lead fills out a form with just their email and company, Breeze appends their job title, seniority, company revenue, employee count, tech stack, LinkedIn URL, and 80+ other fields — automatically, in real time, without the rep lifting a finger. This cleans up your CRM, improves segmentation, and reduces the manual research burden on your sales team. 6sense does something different: it identifies the 3-5% of your total addressable market that is actively researching a purchase decision right now, including anonymous visitors who have never touched your site. The intent model predicts buying stage, surfaces which accounts are in-market, and connects that signal to advertising activation and sales prioritization.
HubSpot-native vs. platform-agnostic
Breeze Intelligence is deeply integrated with HubSpot — it is literally built into HubSpot's interface and sold as an add-on to HubSpot paid tiers. If your company runs HubSpot as its CRM, Breeze is the most natural enrichment layer because the data writes directly to your contact and company records with no middleware. 6sense integrates with Salesforce, HubSpot, Marketo, and other CRMs but is not native to any of them. 6sense is CRM-adjacent — it feeds signals and prioritization into your CRM but lives primarily in its own interface. If your team is HubSpot-native and needs enrichment, Breeze is the path of least resistance. If you are running a multi-system enterprise stack and need intent across all of it, 6sense is designed for that environment.
Price and buyer profile
Breeze Intelligence is bundled with HubSpot's paid tiers and available as a credit-based add-on — meaningfully less expensive than standalone enrichment tools because HubSpot absorbs some of the cost at the platform level. The buyer is a HubSpot admin or RevOps manager adding enrichment to an existing investment. 6sense is an enterprise procurement decision. Contracts typically start at $50,000-100,000 per year and scale from there. The buyer is a VP of Marketing or CMO at a company running a full ABM motion with budget for advertising, demand generation, and sales prioritization. These are different buyers with different budgets.

The verdict
Clearbit/Breeze Intelligence for HubSpot shops that want real-time CRM enrichment without adding another vendor. If your goal is clean contact records, better segmentation, and less manual research, Breeze delivers that natively inside the tool your team already uses every day. The cost is reasonable because it is bundled into an existing HubSpot investment. 6sense for enterprise marketing teams running a full ABM motion — identifying in-market accounts before they raise their hand, activating advertising against those accounts, and feeding buying stage signals to sales for prioritization. The $50K+ price tag is only justified when your average contract value and pipeline volume make intent-driven ABM math work. These tools are not alternatives — they solve different problems at different price points for different buyers.
Is Clearbit the same product now that HubSpot acquired it?
Clearbit was acquired by HubSpot in 2023 and rebranded as Breeze Intelligence in 2024. The core enrichment capability is the same — 85+ data points appended to contact and company records. The key change is the go-to-market: Breeze is sold as a HubSpot add-on, deeply integrated into HubSpot's interface, and priced as part of HubSpot's ecosystem rather than as a standalone product. If you were already using Clearbit with HubSpot, the migration to Breeze is essentially automatic.
What is 6sense's Dark Funnel and why does it matter?
6sense's Dark Funnel refers to the buying research that happens before a prospect ever touches your website or fills out a form — research on review sites like G2 and Capterra, category searches, competitor comparisons, and content consumption that leaves digital signals but does not show up in your CRM. 6sense aggregates these signals and surfaces accounts that are researching your category, even if they have not engaged with you directly. For enterprise SaaS with long buying cycles, identifying accounts in this research phase early gives sales and marketing a head start on accounts that will eventually enter the pipeline.
Can small or mid-market companies use 6sense effectively?
6sense's pricing and complexity are calibrated for enterprise — $50K+ contracts, full ABM teams, and multi-quarter deployment timelines. Some mid-market companies use 6sense successfully, but the ROI math requires a high average contract value (generally $50K+ ACV) to justify the investment. For most mid-market B2B companies under $20M ARR, a combination of Apollo intent signals, Clearbit/Breeze enrichment, and strong outbound is more capital-efficient than a full 6sense deployment.
