AI-powered prospecting search engine for discovering and verifying B2B contact data.
LeadFuze is a contact data infrastructure company that provides identity graph access through three products: an Enrichment API, an Identity Resolution Pixel, and an Intent Data feed. It is not a self-serve prospecting tool with a search interface. It is an API-first data platform that developers and data teams integrate into their own applications, CRMs, marketing automation systems, and AI agents.
Founded in 2014, LeadFuze has repositioned from a prospecting tool to what it describes as a "Contact Data Layer for Apps." The underlying asset is an identity graph covering 269M+ US profiles -- spanning both B2B and B2C identities -- refreshed monthly across 176M+ emails, 131M+ mobile numbers, 101M+ LinkedIn profiles, and 91M+ revenue data points.
The platform bridges B2B and B2C identity, meaning it connects professional data with personal data for the same individual. Its identity graph is fed by a co-op model where member companies contribute anonymized signals in exchange for data access, alongside data partnerships and web tracking.
The most common use case for solo founders and small marketing teams is the Identity Resolution Pixel -- a JavaScript snippet you install on your website that identifies anonymous visitors and enriches them with 50+ data fields including email, phone, job title, company, and behavioral signals like pages visited and time on site. If you have a website generating traffic you cannot identify, this converts some of that anonymous volume into named, contactable leads delivered in real time via webhook.
For development teams and SaaS builders, the Enrichment API is the core product. Submit an email address, phone number, LinkedIn URL, or name plus company, and the API returns a complete profile with 50+ fields in under 200 milliseconds. This powers use cases like pre-filling contact forms, keeping CRM records current, enriching inbound leads at the moment of signup, and grounding AI sales agents with verified contact data.
For data-intensive operations, the Data License delivers the full identity graph -- 269M+ profiles -- to your private AWS S3 bucket on a monthly refresh schedule in Parquet format. This is built for companies building proprietary data products or analytics layers on top of LeadFuze's dataset rather than consuming data point-by-point through an API.
Intent Data is listed as a product covering 5B+ daily signals across 35,000+ B2B categories and 7,000+ B2C categories, but is marked as Coming Soon as of March 2026. It is not yet available.
Install a JavaScript snippet on your website header, configure a webhook endpoint, and receive enriched visitor profiles in real time as people browse your site. Each identified visitor comes with 50+ fields covering emails, phone numbers, LinkedIn profiles, job titles, company data, and behavioral signals including pages viewed, session duration, and scroll depth. A built-in lead scoring model rates visitors from 0 to 100, segmenting them into hot, warm, cool, and cold buckets. A 7-day free trial requires no credit card. A white-label reseller program lets agencies and SaaS companies resell the pixel to their own clients starting at $79/month reseller cost.
A real-time lookup API that accepts four input types -- email address, phone number, LinkedIn URL, or name plus company -- and returns a complete contact profile in under 200 milliseconds. The response includes personal emails, business emails, mobile numbers, social profiles, current employment, job title, and demographic data including homeowner status and net worth range, with a confidence score attached to each record. All API products require custom pricing based on volume and use case.
License the full identity graph of 269M+ profiles delivered directly to your private AWS S3 bucket in Parquet format with monthly refreshes. Supports custom segmentation. Designed for companies building proprietary data infrastructure rather than querying an API at the individual record level. Pricing is custom and requires a sales conversation.
A membership model where companies contribute anonymized data signals -- browsing behavior, contact validations, CRM exhaust -- in exchange for access to the full enriched identity graph. The co-op describes itself as a self-healing ecosystem where cross-referencing member signals continuously improves data accuracy. Membership fees are flat-rate for data licensing with usage-based pricing for enrichment services. Data sovereignty is a stated feature: contributed data assets are removed from the active graph if a member leaves.
Tracks 5B+ daily signals across 35,000+ B2B categories and 7,000+ B2C categories to surface prospects actively researching solutions in a given category. Delivers daily feeds with multi-touch attribution and category precision filtering. Positions as an alternative to Bombora with flexible, volume-based pricing and monthly commitments rather than annual contracts. Not yet available as of March 2026 -- early access waitlist is open.
If you have meaningful website traffic and no way to know who is visiting, the Identity Resolution Pixel converts some of that anonymous volume into named, enriched contacts delivered in real time. The 7-day free trial with no credit card lets you test the match rate on your actual traffic before committing to a paid plan.
The Enrichment API is built for teams that need to enrich contacts at the moment of an event -- a signup, a form submission, a CRM update -- without batch processing delays. Sub-200ms response times and four flexible lookup methods make it a practical fit for real-time application workflows.
The white-label reseller program on the Identity Resolution Pixel is specifically designed for this use case. At $79/month reseller cost with suggested retail pricing up to $999/month per client, the margin structure is clear and the white-label capability means client-facing delivery is under your own brand.

Free Plan: Not available. A 7-day free trial with no credit card is available specifically for the Identity Resolution Pixel.
Identity Resolution Pixel: The product page shows a reseller starting cost of $79/month with suggested resale pricing from $99 to $999 per month per client. End-user pricing for the pixel is not listed publicly -- contact sales for a quote.
Enrichment API: Custom pricing based on volume and use case. No public pricing tiers listed. All inquiries go through the contact form.
Data License: Custom pricing. Delivered monthly to your AWS S3 bucket. Designed for enterprise and data team use cases.
Data Co-Op Membership: Flat-rate membership fees for data licensing with usage-based pricing for enrichment services. Pricing requires a consultation to determine fit and cost.
Intent Data: Not yet available. Early access waitlist is open. Pricing positions as "volume-based, flexible" without minimum commitments, as a contrast to Bombora's annual enterprise contracts.
Annual vs. Monthly: LeadFuze positions its pricing model explicitly as monthly with no annual commitment required -- a stated differentiation from competitors like ZoomInfo and Bombora that typically require annual contracts.
If You Cancel: Data sovereignty is documented as a feature of the Data Co-Op specifically -- contributed data assets are removed from the active graph if a member leaves. For API and pixel products, cancellation terms are not detailed on official pages.
Worth knowing: no product has a publicly listed price beyond the reseller cost indicator on the pixel page. Every engagement starts with a sales contact. If budget predictability matters before talking to a vendor, this is a meaningful friction point.

For teams using Clearbit or Apollo's enrichment layer to fill in missing data on inbound leads, the LeadFuze Enrichment API is a direct substitution, submit an identifier, receive a full profile.
The key difference is coverage of both B2B and B2C identities where most enrichment tools focus on business contacts only.
For de-anonymizing website traffic, the Identity Resolution Pixel competes directly with Clearbit Reveal, Albacross, and similar visitor identification tools. For data teams licensing contact databases from ZoomInfo or Bombora, the Data License and forthcoming Intent Data occupy the same category but with a stated monthly commitment model instead of annual enterprise contracts.
LeadFuze is a data layer that feeds your existing tools rather than replacing them.
Your CRM remains your CRM LeadFuze enriches the records inside it. Your email outreach platform and marketing automation system remain in place -- LeadFuze provides the contact data that populates them.
Your ad platforms continue running, LeadFuze's audience activation and forthcoming Intent Data sync signals into those platforms rather than replacing them.
LeadFuze today is not the same product many people may have encountered under the same name. It has repositioned from a self-serve prospecting tool with a search interface into an API-first contact data infrastructure platform. Anyone evaluating it as a prospecting alternative to Apollo or UpLead will find a different product than expected. The current suite is built for developers and data teams, not for end-users manually searching a contact database.
