Short answer: FullContact is a real, actively-selling identity resolution company, acquired by Ziff Davis in October 2024 and now sitting inside its MarTech division. Its core strength is identity data at scale: a PersonID graph built on Resolve, a 900-plus-attribute enrichment API called Enrich, and a narrower B2B lead-identification point product called Acumen that matches website visitors to LinkedIn profiles. Abmatic AI solves a broader problem: identifying which company and which named person is on a B2B website right now, then personalizing that site and launching outbound and advertising from the same signal, all in one platform. If you need a standalone visitor-ID or enrichment API to feed a stack you already run, FullContact is a legitimate option. If you need identification, personalization, outbound, and advertising off one shared signal, Abmatic AI was built for that. The full comparison, including where FullContact genuinely wins, is below.

What FullContact Is
FullContact is an identity resolution and data enrichment company, acquired by Ziff Davis (NASDAQ: ZD) in October 2024 and now operating inside Ziff Davis's MarTech division alongside Campaigner, Moz, SMTP, Kickbox, and iContact. The company is actively selling under its own brand, "FullContact, a Ziff Davis Company." It runs four named products: Resolve, its core identity resolution engine linking fragmented identifiers (emails, phones, device IDs, social profiles) to a persistent PersonID; Enrich, an API returning 900-plus person-level data attributes from a single starting identifier; Acumen, a B2B lead-identification product matching anonymous website visitors to named individuals and their LinkedIn profiles; and Identity Streme, a first-party data management layer. FullContact reports mapping roughly 248 million U.S. consumer profiles across 50-plus billion identifiers, and cites named customers including Blackbaud, Precisely, ADP, HubSpot, and Copper.
FullContact's center of gravity is consumer-scale identity data for adtech, martech, and fraud/verification use cases, rather than a B2B go-to-market platform. Acumen is the one product built specifically for B2B website-visitor identification: FullContact's own figures put its match rate at 45 to 70 percent of visitors, using deterministic matching against partner data rather than IP-address inference alone, with Slack alerts and integrations into Google Tag Manager, Google Analytics, Segment, Tealium, Adobe Experience Platform, WordPress, and Webflow. Acumen publishes self-serve pricing for two of its three tiers, following a 14-day trial: Essentials at $99 per month and Core at $300 per month; its top Plus tier is quote-based. Resolve, Enrich, and Identity Streme are quote-based. Third-party contract data (Vendr) puts FullContact's average annual contract around $30,152, ranging roughly $6,000 to $83,000, blended across its full product line rather than the B2B visitor-ID use case Acumen serves alone. Our FullContact alternatives guide goes deeper on the wider field of identity-resolution and B2B visitor-ID tools.
One thing FullContact does have that Abmatic AI does not: SOC 2 Type II certification and stated GDPR and CCPA compliance, with a privacy-safe architecture that keeps customer data from pooling into its own dataset. That is a genuine, documented credential worth surfacing plainly rather than glossing over.
What Abmatic AI Is
Abmatic AI is the most comprehensive AI-native revenue platform on the market. It collapses 8 to 12 point tools that mid-market and enterprise B2B teams currently buy separately (VWO, Clay, Apollo, RB2B, Vector, Unify, Qualified (Salesforce), Chili Piper, and BuiltWith, plus a DSP buying tool) into one platform with a shared identity graph and a shared signal layer.
Where FullContact resolves identity and enriches records as its core product, feeding that data into whatever ad platform, CDP, or CRM a customer already runs, Abmatic AI answers the question a B2B revenue team asks first: which company, and which individual person, is on our website right now, and what should happen because of it. The platform identifies both the account and the individual contact behind anonymous website traffic natively, with first-party signal capture across web, LinkedIn, ads, and email feeding one identity graph, no third-party identification partner required. From that same signal, it personalizes the website, launches signal-adaptive outbound sequences through Agentic Outbound, runs Google DSP, LinkedIn Ads, and Meta Ads, and books qualified meetings directly to the right AE's calendar through native AI SDR meeting routing.
Abmatic AI is built for mid-market and enterprise B2B teams, typically a marketing or RevOps group of 3 to 25-plus people at companies with 200 to 10,000-plus employees, running target-account lists from 50 to 50,000-plus accounts. Time-to-value is days, not months: the pixel goes live and first-party signal capture starts the same day it is installed. Pricing starts at $36,000 per year, with enterprise tiers available. See the full platform with a demo of Abmatic AI.
Key Differences: FullContact vs Abmatic AI
Identity Data vs a Full Revenue Platform
FullContact is fundamentally a data company: Resolve builds the identity graph, Enrich returns attributes off it, and Acumen surfaces named B2B visitors from it. What a customer does next, personalize a page, run an ad, send an email, is left to whatever other tools they already own. Abmatic AI's identification is the front door to a platform that already does the next step: personalize the site, trigger outbound, and buy ads off the same identity graph, with nothing to integrate separately.
B2B Visitor Identification Depth
Acumen genuinely identifies individual B2B website visitors, matching anonymous traffic to named people and their LinkedIn profiles, and FullContact publishes real match-rate numbers (45 to 70 percent) rather than leaving it vague, closing part of the same gap RB2B, Vector, and Warmly-class tools target. What Acumen does not do is resolve that visitor to a target-account context: firmographic filtering, an account list, or a buying-committee view. Abmatic AI's contact-level deanonymization and account-level deanonymization both run natively and feed one shared identity graph, so an identified visitor is immediately usable for account-based targeting.
What Happens After Identification
FullContact stops at the data. There is no web personalization, A/B testing, outbound sequencing, or advertising activation anywhere in its product line; Enrich and Resolve are meant to be piped into a customer's own CDP, ad platform, or CRM. Abmatic AI's web personalization, Agentic Outbound, native advertising, and AI SDR meeting routing all run off the same signal that identified the visitor, closing the loop from identified account to personalized page to outbound touch to ad retargeting in one platform.
Compliance Posture
This is the one place FullContact leads outright: SOC 2 Type II certification plus stated GDPR and CCPA compliance. Abmatic AI is not currently SOC 2 certified. If a signed SOC 2 report is a hard procurement gate today, that is a real consideration worth weighing honestly.
FullContact vs Abmatic AI: Head-to-Head Comparison
| Capability | Abmatic AI | FullContact |
|---|---|---|
| Core motion | Identify B2B accounts and contacts, then personalize, activate outbound, and advertise | Resolve and enrich identity data (Resolve, Enrich), with a separate B2B visitor-ID point product (Acumen) |
| SOC 2 Type II certification | Not currently certified | Yes, SOC 2 Type II, plus stated GDPR and CCPA compliance |
| Account-level deanonymization | Yes, native, feeds a shared identity graph for target-account targeting | No native account-list or firmographic ABM layer; Acumen surfaces the visitor's employer as part of a person match, not an account program |
| Contact-level deanonymization (individual visitors) | Yes, native, no add-on, feeds the same identity graph as account-level signal | Yes, via Acumen, deterministic match to a named person and LinkedIn profile, 45-70% published match rate |
| Web personalization | Yes, visual editor plus JSON API, account and persona signal | No |
| A/B testing (VWO / Optimizely-class) | Yes, across web, email, and ads | No |
| Banner pop-ups / on-site CTAs | Yes, signal-gated by account or persona | No |
| Account and contact list building (Clay / Apollo-class) | Yes, first-party DB with firmographic and technographic filters | No; Enrich returns attributes per lookup, not a segmented list product |
| Outbound sequences | Yes, multi-channel, signal-adaptive | No |
| Agentic Outbound (Unify / 11x / AiSDR-class) | Yes, triggers off on-site individual and account intent | No |
| Agentic Chat / inbound (Qualified (Salesforce)-class) | Yes, account and contact aware | No |
| AI SDR meeting routing and booking (Chili Piper-class) | Yes, native | No |
| Technology / tech-stack scraper (BuiltWith-class) | Yes, native | No |
| Advertising (Google DSP, LinkedIn Ads, Meta Ads, retargeting) | Yes, native, account-list driven | No; feeds other platforms' targeting, does not buy media itself |
| First-party and third-party intent | Yes, unified signal layer, individual and account level | No; identity resolution and enrichment, not an intent layer |
| Salesforce / HubSpot integration | Yes, both bi-directional | No documented bi-directional CRM sync; integrates via tag managers, Segment, and Tealium |
| Built-in analytics / RevOps reporting | Yes, native, pipeline and attribution | Acumen dashboard shows visitor activity only |
| Published self-serve pricing | No, sales-assisted | Partial; Acumen from $99/month, other products quote-based |
Eighteen rows, and Abmatic AI covers all but two: SOC 2 certification and Acumen's transparent entry-level pricing, both genuine FullContact advantages. Everywhere a B2B revenue team needs identification tied to personalization, outbound, and advertising in one place, Abmatic AI covers it natively; FullContact hands you identity data and leaves the rest to be built or bought elsewhere.
Skip the manual work
Abmatic AI runs targets, sequences, ads, meetings, and attribution autonomously. One platform replaces 9 tools.
See the demo →Where FullContact Wins
To be fair to FullContact, it beats Abmatic AI on real, specific things:
- SOC 2 Type II certification. FullContact holds a current SOC 2 Type II report and states GDPR and CCPA compliance directly on its site. If your procurement process requires a signed SOC 2 report today as a hard gate, that is a real differentiator Abmatic AI cannot currently match.
- Consumer-scale identity graph breadth. Resolve and Enrich map roughly 248 million U.S. consumer profiles across 50-plus billion identifiers with 900-plus person-level attributes, a depth built for adtech, fraud/verification, and B2C matching a B2B revenue platform was never designed to replicate.
- Transparent entry pricing on one product. Acumen publishes its tiers starting at $99 per month with a 14-day trial, a low-commitment way to test B2B visitor identification without a sales-assisted buying process.
None of that closes the gap on turning an identified visitor into a personalized page, an outbound sequence, or an ad impression inside one platform, which FullContact's product line does not attempt. If your need is genuinely narrow, an identity-resolution API to feed an existing stack, or a compliance-gated process where SOC 2 is non-negotiable today, FullContact is a legitimate choice worth shortlisting. Our full FullContact alternatives guide covers the wider field, and teams comparing the broader category may also find our contact-level identification tools roundup and our Apollo Reveal vs Abmatic AI comparison useful for weighing point tools against a full platform.
Why Teams Choose Abmatic AI Instead
Abmatic AI is the most comprehensive AI-native revenue platform on the market. It picks up exactly where FullContact's identity data leaves off, on one shared identity graph, so a visitor identified the moment they land on your site keeps compounding into personalization, outbound, and advertising instead of sitting in a CSV waiting to be piped somewhere else.
- Contact-level deanonymization, natively, no add-on: identifies the individual person browsing your website anonymously and ties that identity into account-based targeting, not just a lead-alert list.
- Account-level deanonymization: identifies the companies visiting your site in real time, feeding the same identity graph as the individual-level signal.
- Web personalization gated by account or persona signal, so an identified visitor sees a page built for their buying committee, not a generic experience.
- Agentic Outbound (Unify / 11x / AiSDR-class): signal-adaptive sequences triggered off individual and account-level on-site intent, a capability FullContact does not offer.
- Agentic Chat (Qualified (Salesforce)-class): live-site conversational AI that already knows the account and the contact.
- AI SDR meeting routing and booking (Chili Piper-class): inbound and outbound qualified meetings auto-routed to the right AE's calendar, natively.
- Native advertising activation: Google DSP, LinkedIn Ads, and Meta Ads, driven off the same account list and intent signal, channels FullContact feeds but never buys itself.
Deep integrations: bi-directional sync with Salesforce and HubSpot, native Google Ads, LinkedIn Ads, and Meta Ads connections, Slack alerts and AE routing, Gmail and Outlook for sequence sends and meeting booking, and warehouse exports to Snowflake, BigQuery, and Redshift.

Pricing Comparison: FullContact vs Abmatic AI
| Item | Abmatic AI | FullContact |
|---|---|---|
| Starting price | $36,000 per year, enterprise tiers available | Acumen from $99/month (published); Resolve, Enrich, and Identity Streme are quote-based per FullContact's site |
| Reported average contract | Not applicable, single price band published | Around $30,152/year blended across products, per third-party contract data (Vendr) |
| Reported price range | $36,000/year and up | Roughly $6,000 to $83,000/year depending on product and volume, per third-party data (Vendr) |
| Entry scope | Full platform: identification, personalization, testing, outbound, chat, advertising, AI RevOps | Per-product: Acumen (B2B visitor ID) is separate from Resolve/Enrich (identity resolution and enrichment); no bundled revenue platform |
| Add-ons | None, all capabilities included in the platform | Four separately sold products (Resolve, Enrich, Acumen, Identity Streme), each with its own scope and contract |
| Billing model | Annual contract, sales-assisted | Acumen: monthly, self-serve after a 14-day trial. Resolve/Enrich/Identity Streme: sales-assisted, custom-quoted |
| B2B website visitor identification included? | Yes, native, both account and contact level | Yes, via Acumen only; not bundled with Resolve or Enrich |
| Advertising activation included? | Yes, native | No, identity data can feed other platforms' ad targeting but FullContact does not buy media |
FullContact and Abmatic AI price very differently because they sell different things. Acumen is a low-commitment monthly point tool for B2B visitor identification alone; FullContact's other three products are enterprise identity-data contracts priced per volume and use case. Abmatic AI's $36,000-a-year starting price buys one platform that identifies the account and the individual first, then personalizes and activates from that signal, a different job entirely from any single FullContact product. Verify current FullContact packaging directly, since its Resolve, Enrich, and Identity Streme contracts are negotiated case by case. See what the full platform costs on your own traffic with a demo.
Which Should You Choose in 2026?
- Best for a standalone identity-resolution or enrichment API to feed an existing stack: FullContact. Resolve and Enrich are purpose-built for that job at consumer scale.
- Best for procurement processes that require a signed SOC 2 Type II report today: FullContact, on its current certification. Abmatic AI is not currently SOC 2 certified.
- Best for mid-market B2B teams: Abmatic AI, with identification, personalization, and activation running on one signal layer from day one.
- Best for enterprise B2B teams: Abmatic AI, handling tier-1 (1:1), tier-2 (1:few), and broad-based (1:many) programs from 50 to 50,000-plus target accounts.
- Best for identification plus personalization, outbound, and advertising without separate integration work: Abmatic AI. FullContact's products hand you the identity data and stop there.
- Best for fastest time-to-value on a full B2B revenue platform: Abmatic AI, live in days rather than the multi-quarter implementations legacy ABM suites have historically required.
- Best for native agentic AI across chat, outbound, and on-site B2B workflows: Abmatic AI.
Some teams genuinely need both: a company piping FullContact's Enrich data into a warehouse for consumer-profile matching can still run Abmatic AI separately for its B2B identification, personalization, and outbound motion, since the two rarely compete for the same budget line. If what you need is a compliance-certified identity API to plug into a stack you already own, FullContact remains a legitimate, actively-sold choice. If what you need is one platform that identifies who is on your B2B site and then does something about it immediately, Abmatic AI was built for that.

Frequently Asked Questions
Is FullContact still an independent company?
No. FullContact was acquired by Ziff Davis (NASDAQ: ZD) in October 2024 and now operates as "FullContact, a Ziff Davis Company" inside Ziff Davis's MarTech division, alongside Campaigner, Moz, SMTP, Kickbox, and iContact. It is actively selling, not a defunct or dormant vendor.
Does FullContact identify companies visiting a B2B website, or only individual people?
FullContact's B2B product, Acumen, identifies individual people: it deterministically matches anonymous website visitors to named individuals and their LinkedIn profiles, with a published match rate of 45 to 70 percent. It surfaces a visitor's employer as part of that match, but it does not offer a target-account list or firmographic filtering. Abmatic AI identifies both the company and the individual contact natively, feeding one shared identity graph.
Is FullContact SOC 2 certified?
Yes. FullContact holds SOC 2 Type II certification and states GDPR and CCPA compliance on its site, with a privacy-safe architecture that keeps customer data separate from its own dataset. This is a genuine advantage over Abmatic AI, which is not currently SOC 2 certified, and is worth weighing directly if a signed SOC 2 report is a hard requirement today.
What is the difference between FullContact's Resolve, Enrich, and Acumen products?
Resolve is FullContact's core identity resolution engine, linking fragmented identifiers like emails, phones, and device IDs into a persistent PersonID. Enrich is an API returning 900-plus person-level attributes from one starting identifier. Acumen identifies named individuals visiting a website in real time. All three are sold and priced separately; FullContact does not bundle them the way Abmatic AI bundles identification, personalization, outbound, and advertising.
Does Abmatic AI replace FullContact's identity resolution products?
Not for consumer-scale identity resolution or enrichment. Abmatic AI includes account-level and contact-level deanonymization built for B2B website traffic, plus web personalization and a first-party and third-party intent layer, but no general-purpose 900-attribute enrichment API or consumer PersonID graph. Teams with a genuine consumer-scale identity need may keep FullContact for that job while running Abmatic AI for the B2B identification and activation motion.
How does FullContact pricing compare to Abmatic AI pricing?
Acumen publishes pricing for two of its three tiers after a 14-day trial: Essentials at $99 per month and Core at $300 per month; its top Plus tier is quote-based. Resolve, Enrich, and Identity Streme are quote-based; third-party contract data (Vendr) reports a blended average annual contract around $30,152, ranging roughly $6,000 to $83,000. Abmatic AI starts at $36,000 per year with enterprise tiers available, reflecting one full platform rather than a per-product identity-data contract. Verify current FullContact pricing directly, since its contracts are negotiated per deal.
Is FullContact a good fit for enterprise B2B revenue teams?
FullContact's Resolve and Enrich products serve enterprise adtech, martech, and fraud/verification buyers well at consumer scale, and its named customers (Blackbaud, Precisely, ADP, HubSpot, Copper) reflect that. But no FullContact product bundles B2B website identification with personalization, outbound, and advertising activation. Enterprise and mid-market B2B teams needing all of that natively, on one identity graph, are better served by a platform built for that scope. See our FullContact alternatives guide and our B2B website visitor identification setup guide for the wider field.
