Leadpipe offers website visitor identification and sales-oriented delivery. Compare input identifiers, required output and implementation ownership before treating them as substitutes. FullContact publishes identity-resolution and enrichment interfaces. Leadpipe offers website visitor identification and sales-oriented delivery. Compare input identifiers, required output and implementation ownership before treating them as substitutes. This comparison is published by Leadpipe. We reviewed the linked product sources on September 23, 2026. The recommendations below are our interpretation of product fit, not an independent performance test. ## The decision that matters An engineering project that resolves known identifiers has different requirements from a marketing team adding website visitor alerts. Both involve identity data, but a working interface is only part of the end-to-end process. ## FullContact and Leadpipe at a glance | Requirement | FullContact | Leadpipe | | --- | --- | --- | | Main job | Identity infrastructure | Visitor identification | | Product scope | FullContact publishes enrichment and identity-resolution interfaces for linking known identifiers. | Leadpipe offers person-level website visitor identification using its own identity graph, plus API, webhook and CRM delivery. | | Fit to evaluate | A data or engineering team building identity resolution into its own product or data environment. | A team that wants to route eligible website visits into an existing sales workflow. | | Key buying check | Evaluate inputs, identifier persistence, permitted use and deletion behavior. API-level identity resolution and a ready-made visitor workflow require different implementation work. | Test required contact fields on your own traffic. Person-level coverage is strongest in the US; EU/UK defaults to company-level, with person-level requiring affirmative consent. | | Commercial reference | Request current package, usage and contract terms. | Pro 500 is $147/month for 500 identification credits. Trial: 7 days or 500 profiles, whichever comes first, no card. | Sources: [FullContact](https://github.com/fullcontact/fullcontact-go) and [Leadpipe](https://www.leadpipe.com/product/identification/). Product availability and plan terms should be confirmed in the account or order form you will use. ## When to shortlist FullContact A data or engineering team building identity resolution into its own product or data environment. Evaluate inputs, identifier persistence, permitted use and deletion behavior. API-level identity resolution and a ready-made visitor workflow require different implementation work. The useful question is whether this capability removes work or adds evidence at the point where your team makes a decision. Assign an owner to the output before treating it as a benefit. A feed that nobody reviews or a workflow that nobody maintains will not earn its place in the stack. ## When to shortlist Leadpipe A team that wants to route eligible website visits into an existing sales workflow. Test required contact fields on your own traffic. Person-level coverage is strongest in the US; EU/UK defaults to company-level, with person-level requiring affirmative consent. Keep the capabilities you already use in other systems visible. Duplicating a function may simplify a workflow, but that is a hypothesis to demonstrate. Ask the person who operates the current process to complete the same task in the candidate product. ## A practical side-by-side evaluation Write down the identifiers available at the start, the person or company record required at the end and the permitted use. Demonstrate ambiguous inputs, deletion and record updates as well as successful matches. Include implementation ownership in the decision. Record the evaluation in a shared worksheet: | Field | What to record | | --- | --- | | Input | The same accounts, identifiers or eligible traffic, with region and dates | | Required result | Identity level, contact fields and evidence needed for acceptance | | Exceptions | Missing, rejected and unknown cases, with reasons | | Handoff | Destination, owner, duplicates and suppression behavior | | Operating effort | Research, correction, implementation and recurring administration | | Commercial scope | Products, users, usage, term, renewal and data-use rights | Keep unresolved cases visible. A matching name in a database is not independent proof that the person visited your site. For visitor workflows, use [the evaluation kit](/resources/visitor-identification/) and the [person-versus-company explanation](/blog/person-level-vs-company-level-visitor-identification/) to define evidence consistently. ## Compare the complete purchase Get a quote for the workload and package you evaluated. Include required integrations, additional consumption and implementation. If one amount is an annual monthly equivalent and the other is month-to-month, show the commitment separately. Do not assume unused capabilities create a financial return. Divide operating cost by accepted output only after agreeing on the denominator. A company, a suggested contact, a matched visitor and an activated audience are different outputs. Our [pricing framework](/blog/visitor-identification-pricing/) explains how to keep subscription cost and operating effort visible. ## Data handling and geographic scope Request the relevant data-processing terms, source descriptions, retention controls and suppression procedures for the intended workflow. Confirm what changes by country. Contact availability alone does not establish permission to send a campaign, and a vendor’s general compliance statement does not answer every implementation question. ## Where Leadpipe fits Leadpipe supports both account-level and person-level workflows. Its [IP to Company API](/product/ip-to-company/) retrieves stored company information from an IPv4 or IPv6 address; its separate [Identification product](/product/identification/) supplies eligible visitor records and activity. Choose company context for account research and person-level output when the action requires a specific visitor. A company lookup returns no people or visits. Confirm API eligibility and its separate lookup allowance in the [official documentation](https://docs.leadpipe.com/ip-to-company/introduction). Person-level coverage is strongest in the US. EU/UK traffic defaults to company-level identification; person-level requires affirmative consent. Fields can be missing, so judge required output on your actual traffic. If you need research signals from outside your website, evaluate [Orbit](/product/orbit/) separately and check its audience allowances. The [current pricing page](/pricing/) lists Pro 500 at $147/month for 500 identification credits. The trial is **7 days or 500 profiles, whichever comes first, no card**. Confirm the delivery and data-use requirements of your chosen plan. Use the [vendor evaluation kit](/resources/visitor-identification/) to record the same acceptance criteria for every candidate.

FullContact publishes identity-resolution and enrichment interfaces. Leadpipe offers website visitor identification and sales-oriented delivery. Compare input identifiers, required output and implementation ownership before treating them as substitutes. ### Does a larger database mean better results? No. Evaluate relevant, current records that meet your required fields and reach the intended destination. Database size is not a measured outcome for your target segment. ### Can these products work alongside Leadpipe? They can serve different parts of a sales process when the selected plans, integrations and data-use terms support it. Define which system supplies the signal, which owns the contact and which executes the next action. Confirm the actual connection before committing.
