UserGems built its reputation on one thing: knowing when a past buyer changes jobs and turning that into pipeline. What started as a champion-tracking tool has grown into an AI platform for outbound and account-based marketing, aiming to replace the scattered tools that slow down sales teams.
To write this UserGems review, we've analyzed it extensively. We believe it's the ideal choice if:
You run outbound sales and ABM programs where champion relationships drive revenue
You want AI-generated outbound sequences built on real buying signals, not generic templates
You need transparent account scoring that shows reps exactly why a prospect was surfaced
You're a mid-market or enterprise B2B SaaS company with an established CRM and customer base
You want a single platform that combines job-change tracking, intent data, and workflow automation
However, UserGems might not be the best choice if:
You need a B2B contact and company database as your foundation
You require conversation intelligence, website chat, or native advertising capabilities
You want flexible pricing with a free tier or monthly contracts
Your team runs on HubSpot and needs the same integration depth as Salesforce users get
You need data that spans beyond signal-based selling into full GTM operations
In this case, you should consider ZoomInfo: an all-in-one AI GTM platform built on the largest B2B data foundation available (500M contacts, 100M companies, 135M+ verified phone numbers, 200M+ verified business emails), with a GTM Context Graph that fuses your CRM data, conversation transcripts, and behavioral signals into a layer that captures not just what happened in a deal, but why.
Where UserGems focuses on signal-based outbound, ZoomInfo covers the full go-to-market workflow: prospecting, data enrichment, conversation intelligence, marketing automation, and AI-powered execution, accessible through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any third-party tool.
We've included a detailed look at ZoomInfo later in this review as the broader alternative for teams that need more than signal-based outbound. To explore the full platform, you can start a free trial.
What is UserGems?
UserGems was founded in 2015 by Austrian twin brothers Christian and Stephan Kletzl, growing out of Y Combinator's Summer 2014 batch.
Source: UserGems
The original idea was specific: detect when a former customer changes jobs and automatically create a warm lead in Salesforce. The logic was simple. Newly hired executives spend most of their budget in their first 100 days, often re-purchasing tools they trusted at their previous company.
That thesis attracted $22.4M in funding from Craft Ventures, Battery Ventures, Tiger Global, and Uncork Capital. By July 2024, UserGems had generated over $2 billion in pipeline for customers and expanded well beyond job-change tracking into a broader signal platform.
Today, UserGems calls itself "The AI Command Center for Outbound and ABM", targeting B2B revenue teams at mid-market and enterprise SaaS companies.
The platform spans three layers: buying signals, AI-powered account and contact scoring, and an AI agent called Gem-E that drafts personalized outbound sequences. Customers include Salesloft, Mimecast, Sendoso, Docebo, Gong, CrowdStrike, and Outreach.
The company has roughly 100 employees, operates remote-first, and is headquartered in San Francisco.

UserGems Review: How It Works & Key Features
Signals: UserGems consolidates 30+ buying signal types into a single prioritized view.
The Signals layer is the data foundation for everything UserGems does.
It pulls together 30+ native signal types (job changes, website visits, intent data, company news, sales engagement history) into one interface. Teams can also bring in external signals from tools like 6sense, Demandbase, Clay, and G2 through the platform's "Bring Your Own Signals" capability.
The signal library covers several categories. Role change signals track past champions who moved to new companies (converting at 3x normal lead rates), new hires at target accounts (2.5x more likely to buy in their first 90 days), promotions, and buying group member changes.
Buyer intent signals identify specific individuals researching topics across 42,000+ intent topics, de-anonymize website visitors at the contact level, and track competitor research activity.
Source: UserGems
Company-level signals capture funding rounds, mergers and acquisitions, IPO filings, leadership changes, hiring patterns, product launches, and tech stack changes. Sales engagement signals surface previous closed-lost deals, content downloads, and event attendees.
What distinguishes UserGems from most intent platforms is contact-level resolution. Where tools like 6sense or Bombora report that a company is in-market, UserGems identifies which person is doing the research, so reps reach the right individual rather than cold-calling into an organization.
Each signal is scored by recency, relevance to the customer's ICP, and historical deal outcomes. The account-fit layer runs in parallel, evaluating 600+ company attributes drawn from the customer's own sales history.
Gem-E AI Agents: UserGems' AI agent drafts signal-driven outbound sequences and coordinates ABM campaigns.
Gem-E is UserGems' AI agent, launched in January 2025 and available in two modes.
Gem-E for Outbound acts as an AI SDR: it builds contact lists, captures buying signals, scores accounts and contacts, and drafts email sequences, call scripts, and LinkedIn messages. Gem-E for ABM focuses on account prioritization and coordinates sales outreach with marketing ad campaigns.
Source: UserGems
The outbound workflow follows four stages.
First, Gem-E enriches accounts and contacts with missing data. Second, it scores them using signals combined with CRM and third-party intent data. Third, it researches each prospect by analyzing call transcripts and email exchanges to identify buyers' goals, objections, and pain points. Fourth, it drafts multi-step sequences where each follow-on references prior context, keeping the thread coherent.
Rather than personalizing only the first email (a common limitation of AI writing tools), Gem-E layers multiple signals across entire sequences. A single email might reference a competitor intent signal, a closed-lost contact at the account, and recent website activity.
Teams shape Gem-E's messaging through a chat interface, setting company- or campaign-level instructions. Before publishing, admins can preview across 10 sample prospects to check output quality. The resulting emails and tasks go directly into reps' Outreach, Salesloft, or Gong Engage queues, so reps start each day with ready-to-send emails without changing their existing workflow.
For ABM, Gem-E syncs high-intent contacts to LinkedIn, Google, and Meta ad audiences with 80%+ match rates versus the 30% industry average for account-only targeting. Contacts are added or removed dynamically to keep campaigns current.
Account & Contact Scoring: UserGems assigns transparent A-D scores using 600+ criteria trained on your actual deal history.
Account & Contact Scoring is UserGems' AI prioritization layer.
It ranks both companies and individual prospects, telling revenue teams where to focus.
Source: UserGems
The scoring engine evaluates 600+ ICP data points and signal types, updating weekly. The model is trained on CRM data from each customer's closed-won contacts and accounts, so the output reflects that company's actual buyer profile rather than a generic benchmark.
For account scoring, Gem-E evaluates company similarity factors (industry, geography, employee count, tech stack, funding status) combined with live signals (hiring activity, funding rounds, M&A events, closed-lost history). For contact scoring, the model combines persona-match criteria with contact-level signals: past champion status, new hire events, intent activity, website visits, and content downloads.
Scores use an A-D letter scale. Every score shows which signals contributed and why. Admins can adjust the AI-recommended weighting for any signal and preview reranked accounts before committing. No data scientist required.
High-scoring contacts can be added to sales sequences automatically, removing the manual step of copying contacts into outreach tools. The scoring model also feeds Gem-E's ABM workflows, ensuring sales outreach and paid advertising target the same prioritized contacts.
Buying Groups & Workflows: UserGems automatically identifies buying committees and triggers multi-channel actions.
Buying Groups uses AI to identify all stakeholders in a B2B purchasing decision.
It learns from past closed-won deals to determine which personas and roles influenced outcomes, then continuously captures and enriches those contacts at target accounts, even if no rep ever manually added them.
Through Google and Outlook calendar sync, UserGems creates contacts from meetings automatically, including retroactive coverage of historical meetings never logged in the CRM. The platform surfaces accounts where persona coverage is incomplete, alerting teams to gaps before they become deal risks.
Once buying group members are identified, Intelligent Workflows take over. These automations convert signals into predefined actions: creating CRM records, sending Slack alerts, enrolling contacts in sequences, syncing ad audiences, and deploying Gem-E agents, all without manual triage. Workflows support conditional logic for branching by region, persona, ICP tier, or CRM field values.

Where UserGems Falls Short
UserGems excels at signal-based outbound, but several limitations surface when teams evaluate it against their full go-to-market needs.
These reflect a platform built for signal orchestration, not GTM coverage.
No B2B Contact Database. UserGems does not include a B2B contact and company database. It tracks signals about contacts and enriches them, but it doesn't help teams discover new prospects the way a dedicated data platform does. You still need a separate provider for building initial prospect lists, TAM analysis, and market segmentation.
Pricing Accessibility. Annual contracts starting at $33,000/year with no free trial or self-serve option create a steep barrier to entry. Teams cannot validate signal quality against their CRM data before committing. Implementation fees ($3,000-$10,000) add to the upfront cost. Many competing platforms offer free tiers, monthly billing, or trial periods that lower evaluation risk.
Salesforce-First Architecture. UserGems' deepest integration is with Salesforce. Some G2 reviewers flag that HubSpot integration is less mature, which matters as more mid-market companies standardize on HubSpot. Teams running HubSpot should test integration depth before committing.
Adoption Requires Process Change. Customer case studies show that successful implementation demands restructured BDR workflows, redefined ICP criteria, and a commitment to running outreach through Gem-E. Mimecast's adoption required a pilot-first rollout, BDR leadership buy-in, and documented processes before scaling. Teams unwilling to change how reps work each morning will not see the promised ROI.
Limited Scope Beyond Outbound. UserGems focuses on signal detection and outbound execution. It does not offer conversation intelligence, website chat, native advertising (beyond ad audience sync), data quality operations, or full marketing automation. Teams that need these capabilities must maintain separate tools, which reintroduces the multi-tool fragmentation UserGems aims to reduce.
Data Freshness Gaps. G2 reviewers note that data updates sometimes lag, with users receiving duplicate contacts or notifications for job changes that happened longer ago than expected. The mobile experience also trails the desktop product, with a G2 mobile support score of 6.8.
These aren't failures. They reflect UserGems' deliberate focus as the intelligence layer for signal-based outbound and ABM. But they leave a gap for teams that need broad data, full-stack GTM capabilities, and flexible pricing in one platform.
Top UserGems Alternative: ZoomInfo
ZoomInfo addresses UserGems' scope limitations by providing an all-in-one AI GTM platform built on the largest B2B data foundation in the industry.
Source: ZoomInfo
Where UserGems specializes in signal-based outbound, ZoomInfo covers the full go-to-market workflow: B2B data, AI-powered intelligence, conversation analytics, marketing automation, and programmatic access.
Comprehensive B2B Data: ZoomInfo provides the largest verified B2B dataset in the industry, covering contacts, companies, intent signals, and technographics.
ZoomInfo's data platform spans 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct-dial phone numbers, and 200M+ verified business email addresses.
This isn't static data. A multi-source verification pipeline backed by 300+ human researchers and automated ML scanning of 28 million site domains daily delivers up to 95% accuracy on first-party data.
Where UserGems tracks signals about contacts already in your orbit, ZoomInfo serves as the primary source for discovering new prospects entirely.
The platform includes 300+ company attributes for market segmentation, department org charts with decision-makers' direct dials and emails, technographic profiles covering 30,000+ technologies across 30+ million companies, and Buyer Intent tracking from 210 million IP-to-Organization pairings.
Source: ZoomInfo
The data quality is externally validated. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close." ZoomInfo holds Leader positions in both the Gartner Magic Quadrant for ABM Platforms and the Forrester Wave for Intent Data Providers, plus 133 No. 1 rankings on G2.
"ZoomInfo gives us the information we need to execute. It's already there, so we can be three steps ahead." (Vensure Case Study)
GTM Context Graph: ZoomInfo's intelligence layer fuses B2B data with your CRM, conversation transcripts, and behavioral signals to capture why deals move.
The GTM Context Graph separates ZoomInfo from a traditional data provider.
Source: ZoomInfo
It processes 1.5B+ data points daily, unifying ZoomInfo's third-party intelligence with a customer's own CRM records, conversation transcripts (via Chorus), email threads, and product usage data.
CRMs record that a deal moved from Stage 3 to Stage 4. Intent platforms log a research spike. Conversation intelligence transcribes what was said on the last call. The GTM Context Graph connects all three to capture why the deal moved, and what that pattern means for similar accounts.
This context powers every downstream action: follow-up emails that address concerns raised on calls, plays targeting accounts whose signal patterns match actual wins, and forecasts weighted by buying evidence rather than stage labels.
ZoomInfo built this through two decades of data unification infrastructure and context capture engines designed for this purpose. No single point solution can replicate it because no single point solution has the B2B data, the conversation intelligence, and the entity resolution infrastructure at scale.
Seismic's sales team attributed 39% of active pipeline to opportunities identified or influenced by ZoomInfo signals, boosted productivity by 54%, and saved 11.5 hours per week. "That combination of our internal CRM data, external signals, and AI that's given all that context has helped us craft very specific account- and persona-based messages." (Seismic Case Study)
Universal Access: ZoomInfo delivers its intelligence through native seller and marketer front-ends, plus APIs and MCP for any third-party tool.
ZoomInfo's intelligence reaches teams through three channels, so the choice of where to work never limits the intelligence available.
GTM Workspace is where sellers work. AI agents built on Anthropic's Claude handle account research, outreach drafting, signal monitoring, and CRM updates. The Action Feed streams in-market buyers matched to target criteria with pre-drafted actions on every signal. GTM Workspace users report 23% larger pipelines and nearly 60% more meetings per week.
GTM Studio serves marketers, RevOps, and GTM engineers. Teams build audiences using natural language, enrich with first- and third-party data, define triggers, and activate plays across email, calls, ads, and direct mail. Expansion plays that used to take 3 weeks now launch in 30 minutes.

APIs and MCP expose the same intelligence to any custom agent, internal tool, or partner platform. ZoomInfo MCP connects AI models directly to ZoomInfo's B2B data as a native tool. API access is included in all plans.
"The plug-and-play aspect of the API means I can integrate it very easily into any process and get information at a moment's notice." (BDO Canada Case Study)
Flexible Entry Points: ZoomInfo offers a permanent free tier, a 7-day trial, and custom pricing for paid plans.
ZoomInfo provides two no-commitment entry points that UserGems lacks entirely.
ZoomInfo Lite is a permanent free tier (not a trial) with access to ZoomInfo's B2B database, 10 monthly export credits, advanced search filters, the ReachOut Chrome Extension, WebSights Lite (up to 10 website visitor reveals per day), built-in email sending, and HubSpot integration. No credit card, no annual commitment, no time limits.
Source: ZoomInfo
A separate 7-day free trial provides access to core platform features including contact and company search, sales intelligence tools, intent signals, and email outreach with usage limits.
Paid plans are organized across Sales, Marketing, and standalone products (Chorus, Chat), with tiers from Professional through Enterprise. ZoomInfo uses custom-quoted pricing based on seats, credit volume, features, and contract length. The credit system (1 credit = 1 export of a profile) means searching and viewing data within ZoomInfo costs nothing; only exports consume credits.

ZoomInfo does not publish pricing for paid plans but offers a permanent free tier (ZoomInfo Lite) and a 7-day free trial.
Does UserGems offer a free trial?
No. UserGems does not offer a free trial or a free plan. The entry point is a sales-qualified demo followed by an annual contract. ZoomInfo provides two no-commitment options: ZoomInfo Lite, a permanent free tier with access to the B2B database and 10 monthly export credits, and a separate 7-day free trial of the core platform.
What is Gem-E and how does it work?
Gem-E is UserGems' AI agent for outbound prospecting. It enriches accounts, scores contacts using buying signals and CRM data, researches prospects by analyzing call transcripts and emails, and drafts multi-step outbound sequences.
Gem-E achieves 6-20% reply rates compared to the 1-2% industry average for cold outbound. It delivers drafted emails directly into reps' existing tools (Outreach, Salesloft, Gong Engage) without requiring workflow changes.
Does UserGems include a B2B contact database?
No. UserGems tracks signals about contacts and enriches them, but it does not serve as a prospecting database for discovering new contacts. Teams need a separate data provider for initial list building and TAM analysis. ZoomInfo provides a database of 500M contacts and 100M companies with verified phone numbers, business emails, company attributes, and technographics.
How does UserGems handle champion tracking?
Champion tracking is UserGems' foundational capability, built on proprietary data since 2015. The platform detects when past customers, evaluators, or known buyers change jobs and generates warm leads in the CRM. Past champions convert at 3x normal lead rates. Outreach tracked over 5,000 job changes in its first year using UserGems, generating $1.2M in new pipeline.
ZoomInfo also offers champion tracking through its Contact Tracker with job-change alerts, integrated with the broader GTM Context Graph.
What CRMs does UserGems integrate with?
UserGems integrates with Salesforce and HubSpot for bidirectional CRM sync. The Salesforce integration is the primary and more mature connection. Some users report that the HubSpot integration is less developed. UserGems also integrates with six sales engagement platforms: Outreach, Salesloft, Groove, Gong Engage, Salesforce Sales Engagement, and HubSpot Sequences.
ZoomInfo integrates with Salesforce, HubSpot, and Microsoft Dynamics, plus 120 partner integrations in its App Marketplace.
Is UserGems SOC 2 compliant?
Yes. UserGems holds SOC 2 Type 2 certification under continuous external audit and is GDPR and CCPA compliant. All databases and servers are hosted in AWS or Azure with encryption in transit and at rest. Third-party integrations use OAuth2 authorization. ZoomInfo holds ISO 27001, ISO 27701, SOC 2 Type II, and TRUSTe GDPR/CCPA certifications, all renewed annually.
How long does it take to see results from UserGems?
UserGems reports that customers typically see value within 3-4 weeks. Mimecast generated results within 24 hours of launching its first campaign. However, successful adoption requires restructuring BDR workflows and committing to the signal-driven approach. Teams that skip the process-change step are unlikely to see the platform's full ROI potential.
