In contrast, ZoomInfo’s data coverage is limited, particularly when it comes to international coverage and small-to-medium businesses. Their contact data is also insufficient, with gaps below the director level and outside of high-tech industries. ZoomInfo does not offer dynamic data verification processes to add data to the customer’s needs.

At a high level, DealSignal and ZoomInfo offer similar services, but it’s the data coverage where DealSignal excels. With our dynamic and extensive coverage, customers can rest assured that they are getting high-quality and accurate B2B data. In this guide, we’ve explained why we believe DealSignal is the superior option for your B2B lead generation needs.

DealSignal: Overview

DealSignal provides access to an unbelievable 1B+ global companies and contacts with over 100 data points. Our platform was built from the ground up on proprietary data verification processes, regular data hygiene and cleansing, and AI-powered matching algorithms that ensure the highest levels of data and accuracy.

One of the key benefits of DealSignal is our commitment to data quality. We understand how important it is for businesses to have access to accurate and up-to-date information, which is why we have implemented a rigorous data verification process. Our dynamic, multi-step verification process uses AI and machine learning algorithms, robots, and human researchers to re-verify your data just before it’s delivered to you. This ensures that our data is as accurate and reliable as possible, reducing the time and effort required to verify data yourself.

In addition to our commitment to data quality, DealSignal also offers a range of unique features that set us apart from other lead generation platforms. For example, our AI-powered matching algorithms can identify leads that are most likely to convert into customers, based on factors like company size, industry, and buying behavior. This saves you time and money by allowing you to focus your marketing efforts on the most promising leads.

With our dynamic data coverage, we can expand our customers’ data coverage across global markets, industries, and even specific niches within an industry. This means that regardless of your business’s size or target audience, DealSignal has the ability to provide you with high-quality data to support your lead-generation efforts. What’s more, our team of trained data analytics experts can provide real-time data updates, ensuring that our customers always have access to the latest and most accurate data. No other B2B lead generation platform offers the same level of customized and dynamic data coverage as DealSignal.

Overall, DealSignal’s combination of cutting-edge technology, rigorous data verification processes, and unique features make it the ideal choice for businesses that want to streamline their lead generation process and improve the accuracy of their contact data.

ZoomInfo: Overview

ZoomInfo is a well-known B2B leads generation platform that offers access to a large database of company and contact information. Due to it being on the market for such a long time without major updates to its leads generation algorithm, it falls short in terms of data quality and accuracy.

One of the biggest limitations of ZoomInfo is its static data. Unlike DealSignal’s dynamic, multi-step verification process, ZoomInfo’s static database is not tailored to the specific needs of each customer. This can lead to gaps in coverage for specific niches within industries, which can be a significant problem for businesses that require a comprehensive understanding of their target market. ZoomInfo’s lack of customization can also result in weak data coverage for small-to-medium businesses and international markets, where accurate and up-to-date information is crucial for successful expansion and growth.

ZoomInfo - G2 Review

Another drawback of ZoomInfo is its lack of focus on data quality. While they do offer a significant amount of data in their database, there is no guarantee that it is accurate or up-to-date. This can result in wasted time and resources when businesses are forced to manually verify or update their contact lists.

In terms of standard features, ZoomInfo offers many of the same capabilities as other lead generation platforms. They provide access to company and contact information, including job titles, email addresses, and phone numbers. However, due to its archaic database loading process, the accuracy of the data ZoomInfo provides can be heavily compromised and incomplete, demanding considerable manpower and work time by businesses to fill in B2B contact data gaps.

So while ZoomInfo does offer some value as a lead generation platform, its limitations in terms of data coverage and accuracy not only make it less attractive for businesses that want to streamline their lead generation process and ensure the accuracy of their contact data, but its limitations can create inefficient marketing and sales programs and reduce sales productivity.

Features Differences

When comparing the features of DealSignal vs ZoomInfo side by side, it becomes clear that DealSignal offers a more comprehensive and feature-rich solution. For instance, while both platforms provide basic contact information for leads, DealSignal goes beyond the business card by dynamically verifying data in real-time with a combination of AI and human researchers, ensuring that you are always working with the most accurate and up-to-date information.

DealSignal’s unique features include the ability to deliver hyper-targeted leads based on specific criteria such as technographics, intent data, and firmographics, while also providing predictive analytics to help businesses identify high-value accounts and prioritize their sales efforts. This allows sales teams to focus on the leads that are most likely to convert, improving their overall efficiency and success rates.

One of the key advantages of DealSignal is its ability to deliver real-time dynamic data updates. With DealSignal, users can receive timely alerts on changes in their target accounts, such as leadership changes or company expansions. On top of that, DealSignal dynamically verifies and enriches its databases based on our customer‘s sophisticated needs.

In contrast, ZoomInfo’s data updates can take several weeks or even months to be reflected in their static database. This delay can cause businesses to miss out on important information and ultimately harm their sales and marketing efforts. By choosing DealSignal, businesses can have confidence in the accuracy and timeliness of their data, giving them a competitive edge in the market.

Data Accuracy: Dynamic vs. Static

When it comes down to choosing the right B2B sales data tool for your business, data quality might be the most crucial factor to consider. So let’s take a look at the quantity, quality, and types of data that DealSignal and ZoomInfo offer and why we feel DealSignal is the clear winner.

DealSignal’s Dynamic Data

DealSignal offers market-leading data accuracy and quality with access to over 20 million global companies and 100 unique data points per contact. With a sophisticated AI-powered B2B leads generation process, DealSignal guarantees a 97%+ data accuracy rate. DealSignal’s one-of-a-kind Dynamic Data Verification Process updates contact information on a daily basis, expands its database to meet customers’ specific needs, and is not limited by a static database.

DealSignal’s database includes in-depth information on a contact’s profile, allowing customers to filter contacts based on specific skill sets or areas of expertise.

In summary, DealSignal offers a dynamic data verification process that goes beyond just collecting data points, resulting in a market-leading data accuracy rate. With its ability to add data coverage for any industry in any part of the world, customers can have access to the most up-to-date contact information. DealSignal’s database also includes in-depth information on a contact’s profile, providing customers with the ability to filter contacts based on specific criteria.

DealSignal: Data Coverage

With access to over 20 million global companies 1B+ contacts and 100 unique data points per contact, DealSignal’s database is incredibly comprehensive, accurate, and up-to-date. Furthermore, Dealsignal can dynamically add companies and contacts to your list based on your ICP and ideal buyer persona.

In contrast, ZoomInfo dramatically lacks contacts outside of the United States, providing far fewer individual data points, thus making its collected data far too limited and in turn inaccurate. For that reason, many users have reported experiencing a lack of data accuracy of just around 70% due to the lack of features like DealSignal’s AI-powered B2B leads generation process.

In addition to DealSignal’s superior quantity of data points per contact, our Dynamic Data Enrichment Process sets us apart from our competitors. While other companies collect data from publicly available sources and provide static databases, DealSignal actively verifies and updates contact information live and on a daily basis. This means that our database is constantly being enriched with accurate, up-to-date information.

Our system dynamically adds global data coverage for any industry and any company of every size based on our customer’s needs. Whether from small-to-medium businesses to high-tech firms, DealSignal’s dynamic data ensures our customers have access to the most accurate pool of leads available.

DealSignal: Data Quality

DealSignal offers an unparalleled guarantee of market-leading 97%+ data accuracy. DealSignal’s data is verified for accuracy and enriched with additional information such as location, industry, revenue size, title, seniority, and more. This makes DealSignal’s data an invaluable resource for sales and marketing professionals looking for reliable leads across various dimensions.

DealSignal: Data Types

DealSignal provides its users with contact data, account data, intent data, technographic data, and funding data, which all benefit from our one-of-a-kind dynamic data verification process. This means every data point is meticulously verified for accuracy and enriched with additional information such as location, industry, revenue size, title, seniority, and more.

That’s why our dynamic contact data filters through the resumes of potential candidates, getting into the nitty-gritty of their profiles, keywords, and skill sets.

Our advanced filtering system was purpose-built to cater to our customers’ specific needs. For example, when looking for marketing experts, our system filters candidates based on their key skills, such as demand generation and email marketing, rather than simply focusing on their job title. This allows our customers to target their outreach to the exact leads they need, ensuring they’re always making the most efficient and effective use of their time and resources.

ZoomInfo’s Static Data

ZoomInfo is a business information provider that offers a variety of data-related products and services. This widespread focus on individual services has caused a considerable amount of data deterioration in regard to ZoomInfo’s archaic B2B leads gen engine. This may very well compromise ZoomInfo’s usefulness to companies looking for robust contact data.

ZoomInfo 800-lb Gorilla

ZoomInfo’s static data is severely lacking in several key areas. Firstly, their data coverage is weak internationally, and as far as small-to-medium businesses are concerned, focusing almost exclusively on high-tech firms. This means that companies looking to expand globally or target smaller businesses may struggle to find reliable leads through ZoomInfo.

Unlike DealSignal, ZoomInfo does nothing dynamically to add data to the customer’s needs. Their data is static and not updated regularly, which means that customers may be working with outdated information. This can lead to wasted time and resources as sales and marketing professionals pursue leads that are no longer valid.

ZoomInfo: Data Coverage

One of ZoomInfo’s most significant shortcomings is its lack of comprehensive international data coverage, which can be a major drawback for companies looking to expand their reach and generate leads globally. ZoomInfo’s data is heavily focused on the United States, leaving a large gap in its global database. This not only limits their ability to provide accurate information on global companies but also leads to an incomplete picture of the US market itself.

Furthermore, ZoomInfo’s data coverage is weak when it comes to small-to-medium businesses, meaning it may not be a suitable resource for companies looking to target these markets. In addition, ZoomInfo’s contact data weaknesses are apparent, with gaps in information below the director level and outside of high-tech industries. This lack of detailed information can limit the effectiveness of sales and marketing campaigns.

One of the most significant differences between ZoomInfo and its competitor, DealSignal, is the level of dynamic data verification that DealSignal offers. While ZoomInfo collects data from publicly available sources, its data is static and not regularly updated. In contrast, DealSignal actively verifies and updates contact information on a daily basis, ensuring that its database is continually enriched with accurate, up-to-date information.

DealSignal’s system can dynamically add data coverage for any industry in any part of the world based on customer needs, ensuring they have access to the most precise and current contact information available. This feature makes DealSignal the preferred choice for sales and marketing professionals looking for reliable and high-quality data to generate leads and expand their business.

ZoomInfo: Data Quality

While ZoomInfo may promise over 90% data accuracy, its lack of sophisticated AI-powered B2B lead generation processes has led many users to experience 70% data accuracy – at best. This is not ideal for sales and marketing professionals who require accurate and reliable data.

ZoomInfo offers a hand B2B Leads Enrichment Tool, however, DealSignal’s offering is superior in a variety of ways. DealSignal’s B2B Leads Enrichment Tool is powered by sophisticated AI technology that enables it to enrich lead data with up to 100 unique data points per contact.

In addition to its lack of data accuracy, ZoomInfo also falls short in its ability to provide dynamic data verification features that customize its data to the customer‘s specific, sophisticated needs.

ZoomInfo: Data Types

ZoomInfo offers contact, company, intent, and website visitor data. However, without accurate and reliable data, these data types may not be useful for sales and marketing professionals.

Who Has Better Data, DealSignal or ZoomInfo?

When it comes to data accuracy and quality, DealSignal is the clear winner. With its guarantee of 97%+ data accuracy, access to over 20 million global companies and 100 unique data points per contact, sophisticated AI-powered B2B leads generation process, and outstanding verification process that dynamically adjusts to its customer‘s specific needs, DealSignal offers accurate, relevant, and up-to-date data.

While ZoomInfo may have a larger database in terms of raw email contacts, many users have experienced lower data accuracy due to the lack of a sophisticated AI-powered B2B lead generation process, making it less reliable and relevant.


When comparing B2B lead enrichment tools like DealSignal and ZoomInfo, one important factor to consider is their integrations. A good integration can significantly improve the user experience by allowing easy data flow and streamlined workflows. 

DealSignal offers robust integrations with leading sales and marketing tools, including Salesforce, Marketo, HubSpot, SalesForce, SalesLoft, and Outreach. These integrations allow you to seamlessly connect DealSignal’s enriched data with your existing CRM and marketing automation platforms, enabling you to create targeted campaigns and improve sales efficiency.

In comparison, ZoomInfo’s integration options are limited to CRM tools, such as Salesforce, HubSpot, and Microsoft Dynamics, and some ATS platforms, such as Greenhouse and JobDiva. This could pose a challenge for companies that use marketing automation platforms outside of the ones supported by ZoomInfo, as they would need to rely on custom APIs to integrate the two systems.

DealSignal’s wider range of integrations provides greater flexibility for companies of all sizes and types, making it a superior option for companies looking for the best in lead enrichment.


Both DealSignal and ZoomInfo offer various pricing and plan options to cater to different business budgets and needs. However, DealSignal stands out as a more cost-effective solution due to its lower entry-level pricing and no waste on bad data.

On the other hand, ZoomInfo’s pricing can be complicated and confusing. Some users of ZoomInfo have also experienced sneaky auto-renewals of their subscriptions, which can be frustrating and costly.

These auto-renewals are often buried in the fine print of the subscription agreement, making it difficult for users to opt-out or cancel their subscription before the renewal occurs. This lack of transparency and user control can be a major issue for businesses with tight budgets or those looking to switch to a different sales intelligence tool.

In contrast, DealSignal’s transparent and flexible pricing options make it easy for users to adjust or cancel their subscriptions without any hidden fees or lock-in clauses. The team is also willing to work with users to find the best pricing and plan options that fit their specific needs and budget.

Although ZoomInfo may offer similar features to DealSignal, the hidden costs and complexities make it less appealing to most businesses. DealSignal’s transparent pricing, combined with its powerful lead enrichment and verification features, make it a reliable and cost-effective solution for businesses of all sizes.

Customer Support

DealSignal’s customer support team not only provides quick and effective solutions to users’ issues but also takes a proactive approach to improve user experience. For instance, the team conducts regular check-ins to ensure that users are satisfied with the platform and address any concerns before they escalate into bigger issues. Furthermore, DealSignal’s support team is known for its friendly and approachable demeanor, making it easy for users to ask questions and seek help without feeling intimidated.

In contrast, ZoomInfo’s customer support has been criticized for being unresponsive and unhelpful, particularly when it comes to canceling subscriptions. Users have reported that the support team is often unresponsive or unwilling to help, leaving them frustrated and stuck with subscriptions they no longer want.

ZoomInfo Customer Support - Review on G2

DealSignal’s commitment to customer support extends beyond just answering user queries. Their team actively listens to user feedback and incorporates it into the platform’s development. This has led to several improvements and updates to the platform, making it more user-friendly and efficient.

Overall, when it comes to customer support, DealSignal provides a superior and more reliable experience compared to ZoomInfo. The personalized support and proactive approach offered by DealSignal’s team make it a more user-friendly and customer-focused option.

DealSignal vs. ZoomInfo: Which is the best?

While both DealSignal and ZoomInfo offer sales intelligence solutions, DealSignal emerges as the better option for businesses looking for a reliable, cost-effective, and user-friendly platform.

DealSignal’s data intelligence platform provides accurate, verified, dynamic, and enriched leads, making it easier for businesses to identify and engage with potential customers. Additionally, DealSignal’s flexible pay-as-you-go pricing model, combined with an outstanding customer support team, ensures that businesses of all sizes can access high-quality leads without breaking the bank.

On the other hand, ZoomInfo’s complex pricing model, hidden subscription lock-in clauses, and unreliable customer support have been a source of frustration for many users. ZoomInfo’s static contact data with no customer customizability, its hidden costs, and complexities can make it a less attractive option for businesses.

Choosing DealSignal vs ZoomInfo provides businesses with a data intelligence platform that is reliable, cost-effective, and user-friendly. With DealSignal, businesses can easily access verified and enriched leads, allowing them to focus on what they do best – growing their business.
