Alternativas a Clearbit: qué más merece la pena comparar

Clearbit's supplied positioning says it is now Clearbit by HubSpot and evolving into Breeze Intelligence. If that ecosystem direction makes you reconsider your data workflow, decide whether you are replacing enrichment of existing records, anonymous visitor identification, or outbound prospect discovery. Those jobs overlap but are not identical. This shortlist separates account identification from contact sourcing; it does not claim that any candidate reproduces Clearbit's more-than-100-attribute enrichment on the evidence provided.

Choose the job you are replacing

Factors.ai and 6sense address the account-identification side most directly. Seamless.AI and Lead411 are candidates when reachable contacts are the retained requirement. A buyer needing both should demand proof of both, not average the two jobs into a similarity score.

Factors.ai — for website accounts tied to pipeline

Factors.ai combines account identification, buyer-journey analytics, ABM activation, and marketing attribution. It identifies visiting companies and people, enriches accounts, syncs advertising audiences, sends Slack or Teams sales alerts, and connects touchpoints to pipeline. That is a broader operational remit than enrichment alone, bringing account engagement and revenue measurement into the implementation decision.

Factors.ai fits B2B marketers who want visitor identification and account enrichment connected to advertising, sales alerts, and attribution. It is not a narrow attribute-feed replacement. The downside is broader implementation scope: pipeline and audience workflows become part of the system, even if your current need is simply filling gaps in incoming records.

6sense — for an account-prioritization program

6sense identifies anonymous web traffic and combines third-party intent signals with predictive scoring, segmentation, and AI email outreach on top of CRM and marketing automation. Its stated company fit is mid-market and enterprise. This is an account-prioritization and engagement platform, which brings a broader operating commitment than purchasing contact or firmographic data alone.

6sense fits a mid-market or enterprise team turning anonymous traffic and intent into scoring, segmentation, and outreach. It is not a focused purchase for someone who only needs missing contact fields. The downside is the move into a wider account-engagement platform, with new signal definitions and sales processes to validate as well as data matching.

Seamless.AI — for finding people your team can contact

Seamless.AI focuses on finding B2B contacts and companies, with verified emails, direct dials, mobile numbers, advanced list filters, and transfer into CRM and sales-engagement systems. This supports prospecting rather than proving an identical enrichment service. The buyer needs to distinguish obtaining a reachable person from completing an existing record with the required company and person attributes.

Seamless.AI fits outbound teams building prospect lists with email addresses and telephone numbers. It is not established as a replacement for anonymous visitor identification or Clearbit's complete enrichment schema. The downside is that contact discovery may change the workflow rather than replace it; prove existing-record matching if enrichment remains an essential task.

Lead411 — for contact discovery with company and intent signals

Lead411 supplies verified email addresses, direct-dial numbers, company insights, and intent signals for sales, marketing, and recruiting. Advanced search, trigger alerts, and a Chrome extension are named. Its prospecting orientation can change the daily workflow from enriching incoming records to finding people to contact; buyers should establish which of those jobs they actually need to replace.

Lead411 fits teams combining verified contact details with company insights, intent, and trigger alerts. It is not source-proven as a reverse-IP visitor-identification substitute. The downside is narrower documented overlap with that Clearbit use case, so a contact-data demonstration should not stand in for a website-account identification test.

Test enrichment and discovery separately

Build separate test samples for existing CRM records, anonymous site visits, and new prospects. Ask each finalist to demonstrate only the jobs you intend it to replace. Inspect field mappings, match logic, duplicate behavior, and what happens when no result is available. Inventory forms, CRM automations, alerts, and audience rules that depend on current enrichment fields so connector rebuilding is visible in the plan. Confirm data export permissions, retention, and any contractual limits on continued use of supplied data; none are specified here. Train users on the new fields and signals before they trigger sales actions.
