Clearbit extension: HubSpot Breeze and the best replacements

Browser extensions like Clearbit Connect are enrichment tools. They fill in attributes for a profile you're already viewing on LinkedIn or in Gmail. That works for LinkedIn-native ICPs. For teams selling into local businesses, trades, restaurants, or franchise operators where 50%+ of decision-makers have no LinkedIn profile, there's nothing on the screen to enrich. The job-to-be-done is different: discovery (building the universe of businesses and decision-makers from scratch) comes first, enrichment (Clay, Apollo, ZoomInfo, the Clearbit successors) comes second. DataLane sits on the discovery side. Browser extensions sit on the enrichment side.

1. What happened to Clearbit extension

The timeline matters. November 2023. HubSpot announced the Clearbit acquisition (reported ~$150M). Throughout 2024-2025, standalone Clearbit products began consolidation into HubSpot. The Clearbit brand is being phased out in favor of HubSpot Breeze Intelligence. The free Chrome extension (Clearbit Connect for Gmail) had a working version through most of 2024-2025; access has been progressively gated to HubSpot accounts in 2026. The honest framing: Clearbit Connect is partially still alive, but the experience is changing and many of the free workflows users remember have been deprecated or moved behind a HubSpot login.

1.1. November 2023

HubSpot acquired Clearbit for an undisclosed sum, reported at $150M+ across multiple coverage sources. The strategic reasoning: HubSpot wanted native data enrichment to compete with Salesforce plus ZoomInfo's data graph integration. Clearbit's company-enrichment graph plugged directly into HubSpot's CRM workflows, giving HubSpot users automatic firmographic and technographic enrichment without a separate vendor contract.

1.2. 2024-2025

Reveal, Enrichment, Forms Shorten, and other standalone Clearbit SKUs absorbed into HubSpot Breeze Intelligence. Pricing model migrated from Clearbit's per-record enrichment to HubSpot's seat plus records model. Existing Clearbit-direct customers were progressively migrated to HubSpot contracts. The standalone Clearbit pricing page redirected to Breeze Intelligence; the Clearbit dashboard moved into the HubSpot interface.

1.3. Where Clearbit connect stands today

The Chrome Web Store listing for Clearbit Connect still exists. Some legacy users retain access. Particularly those who installed before the consolidation began. New users typically get redirected to HubSpot Breeze Intelligence flows or HubSpot's Sales Hub features. Free Gmail enrichment is no longer the broad self-serve product it was. Teams that relied on the extension as a free-tier productivity layer have been forced to find replacements.

2. What the Clearbit extension actually did (and why people want it back)

Clearbit Connect's value was in three small, high-frequency workflows that compounded across daily prospecting use.

2.1. Gmail hover enrichment

The killer feature. Install in Gmail, hover on any sender, get the company info, role, social links, and sometimes a verified email surfaced inline. No copy-paste, no separate tool, no context switch. This was the workflow that made users evangelize the extension. It removed friction at the most common point of inbox-driven prospecting.

2.2. Email finder inside gmail

Type a name plus company in the compose window, get the email back, ready to send. The pattern matched the actual workflow: thinking about a contact while in Gmail, finding the email without leaving the inbox. Other tools required a context switch to a separate web app or LinkedIn profile.

2.3. LinkedIn profile enrichment

Some versions surfaced company info on LinkedIn profiles directly. Less central than the Gmail use case, but it filled in the firmographic context when the LinkedIn profile itself was thin. Replaced today by Apollo's, Lusha's, and ContactOut's extensions in functionally similar form.

3. Clearbit (now Breeze intelligence)

3.1. Breeze intelligence

Breeze Intelligence (the HubSpot brand for what was Clearbit's core product) handles company enrichment. firmographic data, technographics, company-level signals, intent indicators when paired with HubSpot's other intelligence layers. Critical caveat: Breeze is company enrichment. It doesn't provide contact-level data for individual prospects in the way Clearbit Connect did. For local businesses without HubSpot CRM records, it doesn't help. The product is designed to enrich the records you already have, not to surface new contacts.

3.2. HubSpot free CRM + email tools

HubSpot Free includes some email-tracking features that overlap with what Clearbit Connect did. Open tracking, basic contact enrichment when records exist in HubSpot, sender insight on tracked threads. Limited substitute for the original Clearbit experience because the enrichment scope is HubSpot CRM records only, not arbitrary Gmail senders.

3.3. What's missing

The free, self-serve, "install and immediately enrich any Gmail thread" experience is largely gone. New users in 2026 typically need a HubSpot account, the data is scoped to records inside that CRM, and the friction is meaningfully higher than the original Clearbit Connect workflow. Teams searching for "Clearbit extension" today are usually looking for that lost free workflow. And the right answer is no longer Clearbit, it's a different vendor.

4. The best Clearbit connect alternatives in 2026

All are LinkedIn-dependent contact-data tools. Each works well for LinkedIn-native ICPs and hits the same architectural ~10-20% coverage ceiling for local-business segments.

4.1. Hunter

Hunter has a Chrome extension that mirrors much of what Clearbit Connect did for email finding. Free 25 searches per month, paid plans from $49/month. Strong on email pattern matching plus SMTP verification. The Gmail integration is solid. Install, hover sender, get company info and email pattern. For users who specifically miss the Clearbit Connect workflow, Hunter is the closest direct match in 2026.

4.2. Lusha

Lusha's extension is fast, free for 5 lookups per month, works on LinkedIn and corporate sites. Coverage is mid-tier. Comparable to Hunter for LinkedIn-native ICPs, weaker for non-LinkedIn segments. The extension UX is the cleanest of the major options; for teams that want minimal friction in the in-browser surface, Lusha edges Hunter.

4.3. Apollo chrome extension

Apollo's extension does what Clearbit did plus lets you push the contact straight into a sequence. Heavier UX (more buttons, more options) but higher value for active outbound. The free Apollo tier supports 100 emails per day plus 5 mobile credits per month. Enough to evaluate. Apollo's full pricing covers the upgrade path when the free tier caps out.

4.4. RocketReach

RocketReach focuses on individual contact lookups, particularly LinkedIn-native ICPs. Free tier covers 5 lookups per month; paid tiers handle bulk workflows. Strong for teams that prospect heavily on LinkedIn and want a focused email-finder rather than a full sales platform.

4.5. When none of these work

Every extension above shares the LinkedIn plus corporate-web architecture. For teams targeting local businesses, trades, restaurants, or franchise operators. Where 50%+ of decision-makers have no LinkedIn. Switching extensions doesn't fix the coverage gap. The right answer is a discovery-first complement that builds the universe from license records, permits, POS detection, and franchise filings, then layers contact enrichment. A discovery-first source layer sits alongside whatever LinkedIn-native extension fits the rest of TAM.

5. How to install and use the Hunter or Apollo extension (the practical replacement)

5.1. Installing Hunter chrome extension

Chrome Web Store → search "Hunter" → install → sign in (free account). Use on any company website to surface email patterns; use on Gmail to enrich senders inline. The free 25 searches per month covers low-volume needs; the upgrade to paid is straightforward when the free tier caps out.

5.2. Installing Apollo chrome extension

Chrome Web Store → search "Apollo.io" → install → sign in to Apollo. Use on LinkedIn profiles or company sites to surface contact data and push to sequence. The Apollo extension does more than Hunter (sequence enrollment, dialer access, sequencer triggers) but requires more setup. For teams already evaluating Apollo as a full sales platform, the extension doubles as an entry point.

5.3. Setting up email verification

Both Hunter and Apollo verify emails before send. Always verify executive sends. Bounced exec emails burn sender reputation faster than bounces to mid-level employees because C-suite domains are usually stricter on email security. The verification step adds 1-2 seconds per send and prevents the deliverability damage from rejected addresses.

6. How DataLane fits when the Clearbit extension caps out

The Clearbit Chrome extension (now part of HubSpot's Breeze suite) is a research productivity tool for individual prospectors on LinkedIn-native segments. The extension surfaces what the underlying Clearbit/Breeze graph carries, which is dense for LinkedIn-native enterprise and mid-market and thin for local-business segments where the source pool doesn't extend. DataLane is a discovery-first data layer indexing 17M+ U.S. local business locations from non-LinkedIn sources (licensing boards, permit filings, franchise registries, POS detection, NPI registry). It delivers 60%+ DM mobile coverage at 80%+ accuracy on segments where the Clearbit extension and similar tools return blanks or stale data.

DataLane isn't an extension. It's a batch data feed that supplies the contact universe browser-based extensions can't surface. The pattern: Clearbit extension runs on LinkedIn-native research workflows. DataLane supplies the local-business contact graph at the data-layer step before the workflow begins. For pure LinkedIn-native research, the extension alone is sufficient and DataLane isn't needed.

Frequently asked questions

The Clearbit Chrome extension (now part of HubSpot's Breeze suite) is a real productivity tool for individual researchers on LinkedIn-native segments. The limit is structural: when none of the standard finders work, the segment usually doesn't index in the underlying graph. Mobile coverage on local-business ICPs needs a discovery-first source, not a better extension. For the broader provider landscape, see the B2B data providers buyer's guide.
