SalesIntel vs ZoomInfo: A Head-to-Head Feature Comparison
A quality sales intelligence platform makes getting the data you need and closing more deals easy. In our SalesIntel vs ZoomInfo comparison, we’ll consider several important factors: database size, data quality, ease of use, plans, and pricing. Let’s start with their core capabilities.
What Are the Key Features of SalesIntel and ZoomInfo?
Both SalesIntel and ZoomInfo can be used to source your prospective clients’ contact information. While there are similarities between the software’s key features, they’re far from identical.
SalesIntel
SalesIntel offers research on demand, where a team of over 2,000 researchers will manually verify or find contact information upon request using research credits. This service solves the pain point of accessing highly specific, niche, or hard-to-find contact data that automated systems miss. You can also use their VisitorIntel add-on to identify companies visiting your website through JavaScript tracking, providing company-level identification with daily data refresh.
ZoomInfo
ZoomInfo positions itself as an all-in-one go-to-market platform with AI Copilot (launched in May 2024), which provides sellers with actionable insights, generates personalized emails, and delivers real-time buying signals. Their Scoops feature provides actionable intelligence on key business events like leadership changes and funding rounds, helping sales and marketing teams time outreach efforts effectively.
If you want to do lead sourcing like a pro, this solution offers predictive scoring based on your prospect’s behavior and engagement levels.
Key Takeaway
SalesIntel focuses on data quality and human-powered research services, while ZoomInfo emphasizes AI-driven automation and comprehensive platform features. Your choice depends on whether you prioritize verified accuracy or advanced automation capabilities.
Which is More Accurate: SalesIntel or ZoomInfo?
SalesIntel guarantees 95% data accuracy through a 90-day human verified data process, while ZoomInfo leverages a larger, AI-driven database with continuous real-time updates.
SalesIntel
SalesIntel employs a hybrid verification model where its human verified data contacts are re-verified by a human research team every 90 days to ensure 95% data accuracy. This scheduled, human-led review cycle focuses on quality assurance for premium data, ensuring that updates to contact information are accounted for.
ZoomInfo
ZoomInfo uses a continuous, technology-driven verification model at massive scale, leveraging artificial intelligence and machine learning to process billions of data points daily from web crawlers and a contributory network. This system automatically cleans, updates, and enriches data in real-time rather than using fixed-timed human cycles.
Key Takeaway
This represents a philosophical difference: SalesIntel prioritizes quality assurance through scheduled human verification, while ZoomInfo focuses on scale and speed through continuous automated systems. Choose SalesIntel if you prioritize a 90-day human-verified accuracy guarantee. Choose ZoomInfo if you need the largest possible dataset with AI-driven real-time updates.
Who Has the Bigger Database: SalesIntel or ZoomInfo?
ZoomInfo maintains a vast database with over 321 million professional profiles, while SalesIntel contains over 200 million B2B contacts with no redundancies.
SalesIntel
The SalesIntel platform contains over 200 million B2B contacts and 40 million company profiles, including email addresses and over 48 million direct dial numbers. There are no redundancies within their system, and no matter which plan you choose, you’ll get unlimited data access to the entire database.
ZoomInfo
ZoomInfo has a massive database with over 321 million professional profiles and 104 million companies. However, there are some redundancies, likely because the platform sources contacts from third-party data providers. ZoomInfo offers data segmentation by plan, allowing you to buy licenses for specific data types.
Key Takeaway
While ZoomInfo has a larger contact database, SalesIntel provides unlimited access to more unique business contacts without redundancies. The choice depends on whether you prioritize sheer volume or verified uniqueness.
How Do Integrations Compare Between SalesIntel and ZoomInfo?
Both platforms offer extensive integration capabilities, but with different strategic approaches to connecting with your existing tech stack.
SalesIntel
SalesIntel focuses on being a best-in-class data provider that integrates seamlessly into your existing tech stack. Native integrations include major CRM platforms like Salesforce, HubSpot, Marketo, Microsoft Dynamics, Outreach, Salesloft, and Zoho. They also provide robust API access for custom integrations.
ZoomInfo
ZoomInfo positions itself as the central, foundational data layer for all sales and marketing activities. It has an extensive marketplace of integrations with hundreds of apps, including deep integrations with CRMs like HubSpot, Salesforce, and SugarCRM, plus marketing automation tools and ERPs.
Key Takeaway
SalesIntel emphasizes quality integrations with core sales tools, while ZoomInfo offers broader marketplace connectivity. For maximum flexibility, UpLead’s Zapier integration connects to over 8,000 applications without requiring direct builds.
How Does Buyer Intent Data Differ?
Both platforms offer intent data capabilities, but use different methodologies and data sources to identify in-market buyers.
SalesIntel
SalesIntel combines first-party, third-party, and proprietary AI-driven intent signals. They partner with Bombora to provide Company Surge intent data from the B2B publisher co-op and launched PredictiveIntent in August 2023, a proprietary AI model that predicts intent earlier in the buying cycle using multiple data sets.
ZoomInfo
ZoomInfo gathers data from a vast network of over 300,000 publisher domains and uses patented machine learning to analyze content consumption. They track bidstream data from real-time ad auctions and provide strong technographic data through their Datanyze acquisition.
Key Takeaway
SalesIntel focuses on predictive AI models and Bombora partnership data, while ZoomInfo leverages its massive publisher network and bidstream data. UpLead also partners with Bombora for industry-leading Company Surge intent data, available in Professional and Enterprise plans.
What Is the User Experience and Onboarding Process Like?
G2 reviewers rate SalesIntel higher for Quality of Support (9.2 vs 8.7) and Ease of Setup (9.1 vs 8.9), while ZoomInfo scores slightly higher on Ease of Use (8.8 vs 8.6).
SalesIntel
Users on G2 and TrustRadius frequently describe SalesIntel’s interface as cleaner, more intuitive, and user friendly. The onboarding process is consistently praised as straightforward and quick, allowing sales teams to get started with minimal disruption. Users mention the onboarding and customer success teams are excellent to work with.
ZoomInfo
ZoomInfo’s interface can feel cluttered initially but is easy to use once learned. Its comprehensive database is a major strength, but navigating it can be overwhelming for some users. The implementation is considered effective but may require more guidance from the ZoomInfo team to get started.
Key Takeaway
This represents a trade-off between simplicity and support (SalesIntel) versus feature depth and complexity (ZoomInfo). Choose based on your team’s preference for streamlined onboarding or comprehensive feature access.

SalesIntel is transitioning to a comprehensive pipeline generation platform while maintaining its human verified data core. Recent launches include PredictiveIntent (August 2023), Intent Automations (October 2024), and AdsIntel (January 2025), all developed organically.
The Smarter Alternative: Why UpLead Outperforms Both

UpLead
UpLead’s extensive database contains over 160 million contacts and guarantees 95% data accuracy with real-time verification at the point of download. Our Chrome extension allows for advanced searches and real-time prospecting.
The platform’s intent data feature, powered by Bombora’s Company Surge data from over 5,000 B2B publisher websites, helps you get in touch with potential customers who are already looking for a solution. UpLead also offers three different plans with transparent pricing starting at just $890 annually.
Apollo.io
Apollo.io is an all-in-one sales intelligence and engagement platform that combines a database of over 275 million contacts with outreach automation tools. It offers transparent pricing with a free plan providing 100 credits monthly, and paid plans starting at $49/user/month with comprehensive filtering options.
Cognism
Cognism focuses on globally compliant B2B contact data with unrestricted access models. Their Diamond Data offers phone-verified mobile numbers and compliance with GDPR and CCPA regulations. However, pricing requires custom annual contracts with estimated costs ranging from $15,000 to over $40,000.
Seamless.AI
Seamless.AI positions itself as a real-time AI search engine, scanning over a billion websites and social profiles in real-time rather than maintaining a static database. It offers a free plan with 50 lifetime credits and focuses on individual plan users and smaller businesses with its browser extension for LinkedIn prospecting.
LinkedIn Sales Navigator
LinkedIn Sales Navigator helps you search for potential prospects based on industry, location, and title parameters. Core costs $79.99/month annually, but it lacks direct dial numbers and verified emails without third-party enrichment tools. It’s powerful for LinkedIn-based prospecting but limited for comprehensive contact data needs.
Lusha
Lusha offers a user friendly interface with a generous free plan (5 credits monthly) and credit-based pricing. Pro plans start at $29/user/month annually for 480 credits. However, crucial features like CRM integrations are only available on the custom-priced Scale plan, which can be expensive for growing teams.
