Pick Clearbit if your team runs on HubSpot and you mainly want cleaner, fuller contact and company records. Pick 6sense if you sell to a defined list of target accounts and need to know which of them are researching a purchase right now, and you have the budget and people to run an ABM platform.

That is the short answer. The longer one starts with a fact many comparison pages skip: the Clearbit you may remember is gone as a standalone product.
What happened to Clearbit
HubSpot announced it was buying Clearbit in November 2023. At INBOUND 2024 the product was renamed Breeze Intelligence and folded into HubSpot as a paid add-on that runs on credits. The free tools people used for years, such as the Clearbit Connect Chrome extension and the Weekly Visitor Report, were retired in 2025.
So if you are not on HubSpot, the honest answer to "Clearbit vs 6sense" is that Clearbit is mostly off the table. New teams outside HubSpot can no longer sign up for the old standalone API. If you are on HubSpot, Breeze Intelligence is the version you would actually be buying.

What each tool does
A useful way to frame it: Clearbit answers "who is this?" and 6sense answers "who is ready to buy?" They overlap a little, but they were built for different jobs.
Clearbit (Breeze Intelligence)
- Enriches contacts and companies in your HubSpot CRM with firmographic data such as industry, size and location.
- Shortens forms by filling in known company details, so visitors type less.
- Shows which companies visited your website and how interested they look (HubSpot calls this buyer intent).
- Lives inside HubSpot. Setup is light because there is no separate platform to learn.
6sense
- Collects intent signals from across the web and from your own channels to spot accounts researching your category.
- Scores accounts and places them in predictive buying stages: Target, Awareness, Consideration, Decision and Purchase.
- Matches anonymous website traffic to companies using its own company graph.
- Adds account-based advertising, sales intelligence with contact data, and workflows that trigger when an account moves stage.
Clearbit vs 6sense side by side
- Main job: Clearbit enriches data. 6sense prioritises accounts by buying intent.
- Who can buy it: Clearbit needs a paid HubSpot subscription. 6sense works with several CRMs and ad platforms.
- Pricing: Breeze Intelligence is bought as HubSpot credits. 6sense does not publish prices and sells through its sales team on annual contracts.
- Setup: Clearbit switches on inside HubSpot. 6sense is a platform project that usually needs someone to own it, often in marketing ops.
- Website visitors: both identify the company behind a visit. Neither is built to tell you which person visited.

Which teams should choose which
Choose Clearbit (Breeze Intelligence) if you are already a HubSpot customer, your main pain is half-empty records and long forms, and you want something live this week. It suits small and mid-sized teams that run inbound marketing out of HubSpot.
Choose 6sense if you run account-based marketing against a few hundred or a few thousand named accounts, you advertise to those accounts, and you want sales to call the ones in the Decision stage first. Expect a longer setup than an add-on and a sales-led contract. Teams that buy 6sense without someone to run it often end up using a fraction of it.
Many teams asking this question need neither. If what you actually want is a list of people who visited your pricing page yesterday so a rep can follow up, an enrichment add-on and an ABM platform are both indirect ways to get there.
What if you need the person, not the company?
Company-level identification tells you that someone from a 500-person firm read three pages. Your rep still has to guess who it was and find their details. That guessing step is where a lot of follow-up dies.
Person-level visitor identification closes that gap. Happierleads, for example, identifies the exact person visiting your website (name, email, phone and LinkedIn profile) along with their company, and can send them straight into your CRM, Slack or an email sequence. It is a narrower tool than 6sense and does not depend on HubSpot, which makes it a fit for teams whose real goal is following up with warm website visitors.
Questions to ask before you buy
- Which CRM will we be on in two years? If the answer is not HubSpot, rule Clearbit out now.
- Do we have a named account list, and does sales work from it? If not, much of 6sense will go unused.
- What will a rep do with the data on day one? Write the workflow down before the demo, then ask each vendor to show that exact workflow.
- Do we need companies or people? Be honest here, because it decides the whole category.
Ask each vendor for a trial on your own traffic and compare what they find against visitors you already know. That test will tell you more than any comparison page can.
Frequently asked questions
Is Clearbit still available?
Clearbit now lives inside HubSpot as Breeze Intelligence, a credit-based add-on for paid HubSpot customers. Its free tools were retired in 2025 and new teams outside HubSpot cannot buy the old standalone product.
Is 6sense better than Clearbit?
They do different jobs. 6sense is better for account-based marketing and spotting accounts ready to buy. Clearbit is better for enriching records inside HubSpot with little setup.
Do Clearbit and 6sense identify individual website visitors?
Both match website visits to companies. Neither is built to name the individual person who visited. For that you need a person-level visitor identification tool.
How much does 6sense cost?
6sense does not publish its prices. It sells through its sales team, usually on annual contracts, so you need to request a quote.
