Why Settle for Less? Choose DealSignal Over Zoominfo and Apollo

In a Nutshell

When it comes to picking the right B2B data platform for handling business data, it’s a tough call. You’ve probably heard of DealSignal, ZoomInfo, and Apollo, right? Well, we’re taking a close look at all three to see what’s what. 

Here’s the deal: while ZoomInfo and Apollo have some good points, they also have a few misses, especially in key areas that really matter for businesses. That’s where DealSignal comes in. It’s not just another option; it’s a step up.

We’re going to dive into the important stuff – like how good their data is, what they cover, how they work with other software, how they handle customer support, play by the rules, and what they charge. 

Let’s take a look at these platforms individually, and then see what makes them similar and what makes them different.

ZoomInfo Overview

ZoomInfo is a recognized player in the B2B lead generation space, known for its extensive database encompassing companies and contacts. However, its long-standing presence in the market without significant updates to its lead generation algorithm raises concerns about the freshness and precision of its data.

A notable shortcoming of ZoomInfo is the static nature of its database. ZoomInfo’s data does not undergo continuous customization for individual client needs. This leads to potential gaps in information, particularly in specialized industry segments, posing challenges for businesses seeking a detailed grasp of their target audience. The platform’s one-size-fits-all data model can be particularly inadequate for small to medium enterprises and global markets, where current and precise data is vital for business development and growth.

Furthermore, ZoomInfo doesn’t prioritize the accuracy of its database. While the platform boasts a considerable volume of data, its reliability and timeliness are not assured. This can lead to businesses expanding additional effort and resources in manually checking and updating their contact lists to ensure their accuracy.

ZoomInfo provides standard features comparable to other lead-generation tools, including access to details like job titles, email addresses, and phone numbers. However, the outdated methodology used in populating its database often results in data that is not entirely accurate or complete. This can place a significant burden on businesses, requiring them to dedicate time and resources to address the deficiencies in the B2B contact information provided by ZoomInfo.

Therefore, while ZoomInfo does have some merits as a lead generation tool, its drawbacks in data coverage and accuracy diminish its appeal for businesses focused on efficient lead generation processes and precise contact data. These limitations could lead to ineffective marketing strategies and sales initiatives, ultimately impacting sales productivity.

Alright, let’s switch gears a bit. We’ve just taken a good look at what DealSignal, ZoomInfo, and Apollo are all about. Each has its own flavor, offering different tools and tricks for handling business data. But here’s the real question: how good is the data they provide?

B2B Data Providers: DealSignal vs ZoomInfo vs Apollo


When it comes to the quality of data in B2B lead generation platforms, the comparison between DealSignal, ZoomInfo, and Apollo reveals some clear distinctions.

ZoomInfo: While ZoomInfo has been a long-standing player in the field and offers a sizable database, it falls short in the realm of data freshness and accuracy. One of the major limitations is its static data approach. Unlike DealSignal’s dynamic and customized verification process, ZoomInfo’s database does not undergo regular and individualized updates, which can lead to gaps in information, particularly in specialized segments. This static approach can also result in weaker data coverage for specific markets, such as small-to-medium businesses and international regions.

Apollo: Apollo, with its AI-powered sales intelligence and engagement platform, offers a significant database of contacts. However, the quality of Apollo’s data, while substantial in volume, may not always align with the specific quality needs of diverse businesses. While Apollo incorporates AI for lead scoring and offers real-time lead scoring in its features, the overall depth and accuracy of its data might not consistently match the bespoke and continuously updated nature of DealSignal’s offerings.

DealSignal: The standout in terms of quality, DealSignal prides itself on offering exceptionally accurate and up-to-date information. The platform’s rigorous data verification process is a key highlight, using a dynamic, AI-driven approach. This includes a multi-step verification with AI, machine learning, automated systems, and human analysis, ensuring that the data delivered to clients is of the highest quality. Additionally, DealSignal’s commitment to regular data hygiene and cleansing further underscores our dedication to quality, setting it apart from our competitors.

While ZoomInfo and Apollo provide substantial data offerings, their approach to data quality and accuracy does not seem to be as thorough or customized as DealSignal. DealSignal’s unique combination of AI-driven verification, regular data cleansing, and a focus on real-time accuracy positions us as the superior choice for businesses seeking the most reliable and high-quality B2B data.


The scope and reach of a lead generation platform’s database, or its coverage, is crucial for businesses looking to target a wide and relevant audience. Here’s how DealSignal, ZoomInfo, and Apollo stack up in terms of coverage.

ZoomInfo: ZoomInfo is known for its extensive database, which is one of its main selling points. As of October 2023, ZoomInfo’s database includes over 320 million business contacts and 104 million companies, with a significant focus on North American data. The platform has a long-standing presence in the market, suggesting a broad coverage across various industries and geographies. However, the breadth of ZoomInfo’s coverage may sometimes come at the cost of depth and specificity, particularly in niche markets or for small-to-medium businesses. This can lead to gaps in data for companies that require highly specialized information.

Apollo: Apollo also boasts a large database, claiming over 265 million contacts. This indicates substantial coverage, allowing businesses to tap into a wide array of industries and markets. Apollo’s AI-driven approach to sales intelligence suggests an ability to cater to a broad spectrum of lead generation needs. However, like ZoomInfo, the extent to which Apollo’s coverage is tailored to specific industry niches or unique market demands may not be as comprehensive as DealSignal’s.

DealSignal: DealSignal offers comprehensive coverage with access to over 1 billion global companies and contacts, enriched with more than 100 data points. This wide coverage is particularly beneficial for businesses seeking a broad and deep understanding of various markets. Unlike ZoomInfo, which may have limitations in niche markets and small and medium-sized enterprises, DealSignal’s platform is designed to cater to a diverse range of industries and niches, ensuring that regardless of the size or specific focus of your business, you have access to high-quality data that spans across global markets. The attention to detailed and specific data makes DealSignal an attractive option for businesses that require precision and depth in their lead generation and market intelligence efforts
In terms of sheer numbers, all three platforms provide extensive coverage. DealSignal, however, appears to take an edge with our ability to offer tailored and updated data across a wide range of global markets and industries. While ZoomInfo and Apollo provide wide-reaching databases, they may not offer the same level of specialized and current data for unique business needs, especially in less common market segments or for small and medium-sized businesses. This makes DealSignal a more versatile and reliable choice for businesses looking for detailed and specific market coverage.

Stellar customer support is crucial for navigating any B2B data platform, but when dealing with sensitive data, ensuring robust compliance measures becomes equally paramount. In the next section, we’ll delve into the compliance practices of DealSignal, Apollo, and ZoomInfo, helping you choose the platform that safeguards your data with utmost integrity.


In the realm of lead generation and data intelligence platforms, compliance with legal and regulatory standards is critically important. Here’s how DealSignal, ZoomInfo, and Apollo fare in terms of compliance.

ZoomInfo: While ZoomInfo’s website doesn’t explicitly detail all compliance certifications, its size and established presence suggest adherence to key industry standards like GDPR and CCPA. However, for complete transparency, users might prefer more readily accessible information on their compliance measures.

Apollo: Apollo clearly states its GDPR compliance on its website, showcasing a commitment to data privacy in the European Union. This is a significant indicator for companies operating internationally. However, further information on additional certifications or regional regulations they adhere to could be beneficial.

DealSignal: DealSignal’s Privacy Policy underlines our dedication to user data security and GDPR and CCPA compliance. We actively assist users in adhering to these regulations by identifying contacts from governed regions and allowing their exclusion from data requests, minimizing risk and ensuring privacy. Additionally, DealSignal details our data usage practices (including cookie utilization for analytics and user experience) and user rights like access, correction, deletion, and opt-out (including CCPA-specific provisions).

Conclusion: Overall, all three platforms prioritize compliance to varying degrees. DealSignal’s emphasis on user data protection through features like contact filtering and transparency in its Privacy Policy stands out. However, users seeking platforms with readily accessible and detailed compliance information might find Apollo’s website statement or further research on ZoomInfo’s practices helpful. Ultimately, the choice depends on individual priorities for compliance clarity and specific data security needs.

Now that we’ve explored the data security landscape of these platforms, another crucial factor to consider is pricing. In the next section, we’ll delve into the pricing structures of DealSignal, Apollo, and ZoomInfo, helping you find the option that best aligns with your budget and data needs.
