Understand your customers beyond just their name and email address
FullContact is an identity resolution and enrichment company: it links fragmented customer identifiers (email, phone, name, Mobile Ad ID, etc.) into a single, real-time customer record via its Identibase / Person-Centered Graph, then appends 900+ data attributes for enrichment, targeting, and - per a newer offering - direct access for AI agents via an MCP server.
FullContact's core technology is Identibase, a patented Person-Centered Graph that resolves fragments of customer data (an email, a phone number, a name) into a unified profile, then layers on enrichment (Person Insights, demographic, professional, and consumer-interest bundles) and identity/recognition products (Resolve, Identity Streme) for martech/adtech platforms, consumer brands, and publishers. Its newer FullContact MCP product exposes that same enrichment/identity data to AI agents directly, though it is explicitly labeled a customer preview rather than a generally available product.
Martech/adtech platforms wanting to offer a unified customer view to their own clients, consumer brands wanting real-time person recognition without handling raw PII themselves, and publishers connecting anonymous web traffic to identified, targetable segments.
The FullContact MCP server - the feature most relevant to AI-agent workflows - is explicitly described as a 'customer preview' with 'Request Early Access' as the only call to action, so teams needing production-ready, generally-available AI-agent access to this data today are ahead of where the product currently is. We could not retrieve any pricing information at all, so cost-sensitive teams cannot evaluate fit without contacting sales directly.
No curated rival set covers this tool yet, so these are simply other tools in the same architectural layer and product form. Treat it as a starting point, not a shortlist.
Yes, called FullContact MCP - it's described as giving AI tools like Claude access to enrichment data by adding a FullContact API key to the MCP server, with a documented Quickstart, Authentication page, and a tool reference for 'enrich_person.' The vendor's own marketing page labels it a 'customer preview' available via 'Request Early Access,' not general availability.
FullContact's patented identity graph, which it searches to generate insights based on profiles and associated data for consumer modeling and real-time identity resolution.
A real-time RESTful POST to /v3/person.enrich with a Bearer-token Authorization header and a JSON body containing whatever identifiers you have (email, Twitter, full name, etc.); the documented example response includes fields like fullName, ageRange, gender, location, title, organization, and social profile URLs.
This is an absence in what we retrieved, not evidence the product is free or unusually priced - contact the vendor directly.
The marketing site organizes enrichment into four categories: Individual (330+ attributes spanning behavioral insights, census info, education, hashed emails/mobile ad IDs), Demographic (household data, marital status, net worth, region), Professional (job title, organization, business email/phone), and Consumer Interest (four affinity categories drawn from 100M+ unique monthly users).
This page tells you whether FullContact fits. Cheetah builds and runs the system it goes into — enrichment, sequencing, CRM and the joins between them.
