Broker profile

Clearbit

A B2B data-enrichment platform that turns anonymous website visitors and partial CRM records into company and contact profiles covering work emails, job titles, company size, employee counts, and firmographic signals sold to sales and marketing teams. Founded in 2015 in San Francisco, it was acquired by HubSpot in 2023 and folded into the HubSpot Breeze Intelligence offering. Its signature product, Reveal, identifies the company behind an anonymous IP address to deanonymize website visitors - the same enrichment niche as the larger, publicly traded ZoomInfo and the similarly sized RocketReach, yet with no IRPA settlements to date.

Each broker is scored 1 to 4 across the six dimensions above; higher means more exposure, and the overall gauge is their average.

What each dimension means
  • Data published: how much and how sensitive the personal data they put out.
  • Re-listing frequency: how quickly you reappear after opting out.
  • Complaint record: the volume and pattern of complaints across BBB, Trustpilot, and Sitejabber. No listing, or a listing with no reviews, counts against the broker.
  • Opt-out friction: how hard the removal process is to complete.
  • Operator opacity: how hidden the operating company and its principals are.
  • Prior data incidents: history of breaches or leaks of the data they hold.

Background

Background

Company history

Clearbit's product is B2B data enrichment for go-to-market teams. Marketers, sales reps, and ops teams pipe partial customer records (often just an email address) into Clearbit's API and receive back fuller profiles - company name, employee count, industry, technology stack, job titles, social profile links. The flagship Reveal product identifies the company behind an anonymous website visitor's IP address so marketers can target accounts rather than individual leads. Since December 2023 Clearbit has been a HubSpot subsidiary; its data is now baked into HubSpot CRM and the broader Breeze Intelligence platform.

"Clearbit by HubSpot" + Breeze Intelligence

Clearbit was founded in 2015 in San Francisco by a small group of engineers. The product pioneered a developer-first take on the B2B data category. Instead of selling per-seat subscription access like ZoomInfo, Clearbit shipped REST APIs for enrichment, made the documentation excellent, and grew bottom-up through engineering teams. The company raised about $17 million across rounds led by Bedrock, Battery Ventures, Cross Creek, and Zetta Venture Partners, reaching a $250 million valuation as of January 2019.

On November 1, 2023, HubSpot announced its acquisition of Clearbit for $150 million all-cash (disclosed in HubSpot's November 8, 2023 10-Q). The strategic rationale, per HubSpot's filings, was to bring "rich third-party company data into [HubSpot's] system of record" - making the Clearbit dataset a standard layer in every HubSpot customer's CRM rather than a separate paid product. Post-acquisition the founders left active operations; the product has been rebranded under "Clearbit by HubSpot" and incorporated into HubSpot's Breeze Intelligence unified intelligence offering. The clearbit.com domain still routes most visitors to HubSpot's product page.

Clearbit is a different kind of "data broker" than the people-search brokers in this directory. Like ZoomInfo, RocketReach, Acxiom, and Epsilon, Clearbit is enterprise-facing - the data lives in paid APIs and CRM integrations consumed by sales, marketing, and ops teams, not in a consumer-search page. The privacy concern remains real. Your name, job title, employer, work email, and social profiles get aggregated and surfaced to anyone paying for enrichment, without you ever signing up or being notified.

The Reveal product is the distinguishing item. Where ZoomInfo and RocketReach focus on contact discovery (lookup an email to find a person), Clearbit also runs Reveal: a marketer drops a tracking script on their website, Clearbit ingests the visitor's IP address, and Reveal returns the company that owns that IP block - effectively de-anonymizing unauthenticated B2B website traffic. This is the product HubSpot most aggressively integrated post-acquisition.

Data Published

Data types

Company + contact enrichment
  • Company firmographics: legal name, industry, employee count, revenue band, founded year, funding history

  • Company technographics: website technology stack, marketing tools in use, hosting providers

  • Company location and ownership: HQ address, jurisdiction, public / private status, parent company

  • Person-level data: full names, work email addresses (often inferred via domain patterns), job titles, employment history

  • Social profile links: LinkedIn, Twitter, GitHub, AngelList, Crunchbase

  • IP-to-company reverse-lookup database (the Reveal product): identifies which company owns a given IP block

  • Anonymous website-visitor identification: site owners who embed Clearbit's tracker see the companies whose IPs visited

  • Account-data for direct Clearbit customers (now blended with HubSpot account-data post-acquisition)

How the data is sourced: Primarily web scraping of public sources (corporate websites, LinkedIn, Crunchbase, press coverage), supplemented by data partnerships and a contributor network where customers share back enrichment results. Work email addresses are frequently inferred via name-format pattern matching against the target company's domain rather than scraped directly. IP-block ownership data comes from regional internet registries (ARIN, RIPE, etc.) and from Clearbit's own tracker observations across the web.

Opt-out limitation specific to Clearbit's API model: Even after a successful opt-out, Clearbit's docs note that the suppression "stops your data from being served through their API going forward but does not recall data that has already been delivered to their customers." Once a HubSpot or Clearbit customer has pulled your record into their own CRM, that downstream copy is no longer under Clearbit's control - you'd need to contact that downstream customer directly to delete their copy.

HubSpot subsidiary · B2B-enrichment peer group

Clearbit sits inside HubSpot post-November 2023. The relevant comparisons are HubSpot's own ecosystem (one parent, one privacy framework) and the broader B2B enrichment peer group.

Cross-category comparison: within this directory, the closest analogs are ZoomInfo and RocketReach. All three are B2B contact-enrichment brokers; Clearbit differentiates with the Reveal IP-to-company product, ZoomInfo dominates on database scale, and RocketReach competes on price. Acxiom (Omnicom-owned) and Epsilon (Publicis-owned) are larger but operate in consumer-marketing data rather than B2B enrichment. Foursquare covers location intelligence, a different category.

An opt-out at Clearbit covers Clearbit's holdings only

The suppression applies to Clearbit's API and enrichment results. Because Clearbit is now part of HubSpot, HubSpot's broader customer-data infrastructure may also hold copies of your data through other product surfaces - those are not automatically suppressed by a Clearbit opt-out. For full coverage across HubSpot's products you may need to submit through the HubSpot privacy portal as well. And opting out at Clearbit does not propagate to ZoomInfo, RocketReach, Apollo.io, Lusha, or other B2B enrichment peers - each has its own opt-out path.

Reputation

Trust signals

Enterprise-skewed; clean private-litigation record

Clearbit's review presence is overwhelmingly B2B (G2, Capterra, TrustRadius) rather than consumer-facing - customers rate the data quality, API reliability, and pricing rather than a consumer-side privacy experience. Unlike ZoomInfo and RocketReach, Clearbit has not been the named defendant in a public IRPA or BIPA class action, which is a meaningful clean signal in this category.

  • Personal data (name, work email, job title) appearing in third-party CRMs without the data subject's signup or notification

  • Cold sales outreach citing Clearbit-sourced contact info, particularly to senior employees and decision-makers

  • Inferred work email addresses being incorrect, leading to bounced outreach (a quality complaint that affects subjects and customers both)

  • Reveal product de-anonymizing company visits in a way some companies find privacy-invasive (network-level rather than person-level)

  • Post-acquisition uncertainty about which entity holds the data and how to route privacy requests (Clearbit's privacy email + HubSpot's privacy portal both being valid)

Litigation

Litigation history

None confirmed · clean record

No confirmed FTC enforcement action, state Attorney General consent decree, CCPA / CPRA enforcement, or named consumer class action against Clearbit, Inc. or its post-acquisition parent HubSpot, Inc. specifically tied to Clearbit's data practices as of the last-updated date. This is meaningfully different from Clearbit's B2B-contact peers. ZoomInfo settled the Ramos IRPA case for $29.55M in November 2024, and RocketReach settled the Krause IRPA case for $1.59M, with final approval in September 2023. Clearbit so far has avoided that litigation wave.

Related and contextual matters:

  • HubSpot parent-company litigation - because HubSpot, Inc. is publicly traded (NYSE: HUBS), its securities and corporate matters are visible in SEC filings. No matters specific to Clearbit's data-broker practices on the post-acquisition public record as of the last-updated date.
  • The Illinois Right of Publicity Act wave - Clearbit's B2B peers have been hit harder under IRPA than any other privacy statute. Why Clearbit has so far avoided this is not publicly explained; possible factors include Clearbit's API-first product model (no consumer-facing search previews of the kind that drove the ZoomInfo and RocketReach cases), the developer-customer base, and the HubSpot acquisition consolidating the data into a CRM context rather than a standalone search product.
  • No state Delete Act enforcement against Clearbit under California's data-broker framework specifically. The CCPA opt-out form at clearbit.com/ccpa-opt-out indicates Clearbit treats itself as subject to the CCPA / CPRA framework rather than disputing it.

FAQ

Q & A

Common questions
Is Clearbit a data broker?

Yes. Clearbit is a B2B data-enrichment broker that sells (now licenses to HubSpot subscribers) data about companies and the professionals who work at them, covering firmographics, work emails, job titles, technographic signals, and anonymous-website-visitor identification. Since December 1, 2023, Clearbit has operated as a subsidiary of HubSpot, Inc. (NYSE: HUBS), which announced the roughly $150 million cash acquisition on November 1, 2023, disclosed it in its 10-Q filing, and reported the December 1 closing in its fiscal 2023 10-K. Post-acquisition the data has been integrated into HubSpot's product family and is also marketed under the Breeze Intelligence brand.

Who owns Clearbit?

Clearbit, Inc. has been wholly owned by HubSpot, Inc. (NYSE: HUBS) since December 1, 2023, when HubSpot closed the roughly $150 million all-cash acquisition it announced on November 1, 2023 and disclosed in its November 8, 2023 10-Q. The closing date comes from HubSpot's fiscal 2023 10-K. Founded in 2015 in San Francisco, Clearbit had raised approximately $17 million in venture funding from Bedrock, Battery Ventures, Cross Creek, and Zetta Venture Partners, reaching a $250M valuation as of January 2019. Post-acquisition, the founders have moved on; HubSpot's go-to-market leadership oversees the product.

What information does Clearbit collect?

Clearbit holds two intertwined datasets, one of company firmographics (industry, size, revenue, technology stack, funding history, location) and one of person-level data (full names, work email addresses, job titles, employment history, social profile links). The data is sourced through web scraping of public sources (corporate websites, LinkedIn, public press) supplemented by data partnerships and a contributor network. Clearbit also runs IP-to-company reverse lookup (the "Reveal" product) which identifies the company behind an anonymous website visitor's IP address - this is sold to marketers for retargeting and lead identification.

Can I remove myself from Clearbit?

Yes. Clearbit honors CCPA / CPRA and GDPR opt-out and deletion requests. Deletion and other requests go through Clearbit's Privacy Request form at preferences.clearbit.com, or call (866) 241-4820 during business hours. California residents who only want to opt out of the sale of their data can instead email privacy@clearbit.com with their name, email address, and postal address, as clearbit.com/ccpa-opt-out directs. Since the HubSpot acquisition, the HubSpot privacy portal at legal.hubspot.com/privacy-policy also routes Clearbit requests. An opt-out stops Clearbit from serving your data through its API in the future, but it does not recall data already delivered to Clearbit customers. See our Clearbit removal guide for instructions.

How long does Clearbit take to remove information?

Clearbit doesn't publish a timescale. As a data broker subject to CCPA / CPRA, it has 45 days to act on a verified deletion request, extendable once to 90 with notice. Once the request is processed, your record should be removed from future API responses and enrichment results. Annual re-submission is the standard maintenance pattern since Clearbit continuously rescrapes public sources.

Is Clearbit covered by FCRA?

No. Clearbit is not a Consumer Reporting Agency under the Fair Credit Reporting Act. Its data is B2B firmographic and contact enrichment, not consumer reports, and the terms of service prohibit use for FCRA-covered decisions (employment screening for compliance purposes, tenant screening, credit, or insurance). The applicable framework is state-level privacy law (CCPA / CPRA, plus VA / CO / CT / UT etc.) and GDPR for EU / UK residents. Unlike its B2B peers ZoomInfo and RocketReach, Clearbit has not been the target of a public Illinois Right of Publicity Act class action or other notable private litigation on the public record as of the last-updated date.
