Updated onMar 14, 2025
ZoomInfo Sales has established itself as a leading lead generation platform, offering extensive B2B contact data and company information to power outbound sales strategies. However, the platform’s complexity, pricing structure, and support model may not be ideal for every sales organization. Depending on your specific sales approach, team size, and priorities, several alternatives might better serve your needs. Whether you’re focused on phone-based outreach, relationship-driven enterprise sales, require responsive support, need quick adoption, or run a small business seeking an all-in-one solution, specialized alternatives like Cognism, LinkedIn Sales Navigator, Clay, Seamless.AI, and Apollo offer distinct advantages that could make them more effective choices for your specific use case. This comparison explores when and why you might choose these alternatives over ZoomInfo Sales in 2025.

Best alternatives to ZoomInfo Sales

For teams prioritizing phone-based outreach:

Cognism product logo

Cognism

Stackfix Rating:

5.1 / 10

Sales teams focused on phone-based outreach will find Cognism’s mobile data quality and verification processes make it a more effective choice than ZoomInfo. While both platforms offer extensive contact databases, Cognism stands out with its specialized phone data verification team that manually validates mobile numbers—these premium contacts are distinctively marked in the interface. Additionally, Cognism’s streamlined, intuitive interface allows sales teams to quickly find and connect with prospects, avoiding the overwhelming complexity of ZoomInfo’s feature-heavy platform that can slow down phone-focused workflows.

For relationship-driven enterprise sales:

LinkedIn Sales Navigator product logo

LinkedIn Sales Navigator

Stackfix Rating:

6.0 / 10

LinkedIn Sales Navigator is a strong alternative to ZoomInfo Sales for relationship-driven enterprise sales, thanks to its unique network intelligence capabilities. While ZoomInfo focuses on raw contact data, Sales Navigator excels at mapping warm introduction paths through existing connections, leveraging LinkedIn profile integration with considerable depth. The platform’s ability to leverage team networks helps sales teams identify the optimal path to decision-makers, and its AI network insights provide strategic advantages that ZoomInfo cannot match. Additionally, Sales Navigator’s intuitive interface makes it easier for enterprise teams to navigate complex organizational relationships. For sales teams prioritizing relationship-based selling over cold outreach, Sales Navigator’s native integration with LinkedIn’s professional network creates more authentic, warm connections that drive higher engagement rates.

For teams needing responsive customer support:

Clay product logo

Clay

Stackfix Rating:

7.7 / 10

Teams seeking responsive customer support will find Clay’s approach significantly more effective than ZoomInfo’s. Clay’s embedded chat widget provides instant AI-powered assistance that successfully handles most queries, with seamless handoff to human agents within an hour when needed. Its help center stands out for its clarity and comprehensive resources. In contrast, ZoomInfo’s support relies heavily on sales-focused account executives who often take over 24 hours to respond, lacks in-app chat support, and maintains an overwhelming, difficult-to-navigate help center. Clay offers a superior customer support experience.

For teams requiring quick platform adoption:

Seamless.AI product logo

Seamless.AI

Stackfix Rating:

5.8 / 10

Seamless.AI’s streamlined interface and rapid setup process make it a better choice for teams prioritizing quick platform adoption than ZoomInfo Sales. ZoomInfo requires multiple sales demos and a week-long configuration process, while Seamless.AI offers a self-serve trial with a 5-minute initial setup. Seamless.AI’s minimalist design and intuitive navigation also allow new users to master core prospecting features in under 15 minutes, compared to ZoomInfo’s overwhelming interface that takes a full day to learn.

Jump to product

For small businesses needing an all-in-one sales solution:

Apollo product logo

Apollo

Stackfix Rating:

7.4 / 10

Small businesses seeking an all-in-one sales solution will find Apollo performs better than ZoomInfo in three crucial areas. First, Apollo offers native email sequencing functionality with advanced features like A/B testing and multi-channel campaign management, while ZoomInfo requires additional tools for email outreach. Second, Apollo provides a more accessible setup experience with self-serve trials and intuitive onboarding that takes under 30 minutes to master, compared to ZoomInfo’s mandatory sales demos and day-long learning curve. Finally, Apollo delivers superior customer support through live chat with quick first-response resolution, whereas ZoomInfo’s support is sales-focused with response times exceeding 24 hours.

Functionality

7/10

<p>ZoomInfo is not a rounded lead generation tool. Instead its best viewed as a very powerful lead generation platform - its contact database is one of the largest and most accurate on the market and its intent data, filtering granularity and data richness is second to none. However, it lacks any kind of email sequencing functionality meaning you'll still need to pay separately for a dedicated CRM/engagement platform. It's worth noting, though, that you can still make phone calls directly from the platform.</p>

Functionality

3/10

<p>Cognism's functionality is very limited. Whilst it does offer one of the largest contact databases on the market with a relative strength in mobile data - the product does very little beyond that.</p><p>We were disappointed by the omission of any kind of outbound functionality (email or phone) and were not impressed by the quality of other facets of the product including the granularity of filter provided or the lack of any material automation/AI features.</p>

Functionality

<p>LinkedIn Sales Navigator is not your typical lead generation tool. Instead its best viewed as a <span style="color: rgb(0, 0, 0);">way to leverage LinkedIn's vast network to identify leads and the best path to reach them via you and your team's connections. As such, its database does not provide emails or phone numbers, meaning you'll still need to find these on a different platform. </span></p><p><span style="color: rgb(0, 0, 0);">However, it does excel in a number of areas such as LinkedIn messaging, the granularity of its data and filtering options as well as its relationship/network mapping features. The ability to know the 'best path in' to contact a lead is something unique to Sales Navigator that can only be done using LinkedIn's vast network.</span></p>

<p>Clay is not your typical lead generation tool. <span style="color: rgb(0, 0, 0);">Instead of using one proprietary database, Clay integrates with dozens of underlying providers (such as Apollo, Hunter, RocketReach etc.) to allow you to pick and choose the best data from almost anywhere. Its spreadsheets and tables focused interface shines when it comes to list building and enrichment tasks in particular. Additionally, when tested, we find its AI features to be well executed and sprinkled in all the right places.</span></p><p><span style="color: rgb(0, 0, 0);">However, Clay does not provide any kind of outbound or CRM style functionality meaning you'll still need to pay for dedicated tooling in these spaces separately. </span></p>

<p><span style="color: rgb(0, 0, 0);">Seamless.AI is best viewed as a lead generation platform as opposed to a rounded lead generation platform. When it comes to prospect search, its database is one of the largest on the market and its prospecting interface covers all the basic filters you'd expect. However, adjacent features around email engagement are omitted entirely meaning that you will need to pay for dedicated outbound tools separately. However, Seamless.AI do provide a email/message personalisation AI feature which integrates nicely across the product.</span></p>

Functionality

9/10

<p>As a lead generation platform, Apollo is mature, rounded and feature rich. It covers the basics well - including a large contact database, strong email verification and granular prospecting and lead scoring tooling.</p><p>Additionally, its adjacent functionalities are also well executed. For example, its outbound sequencing feature is powerful and well integrated. Additionally, small AI touches are well dispersed across the platform - such as a native call transcription and summarisation bot for prospect meetings.</p>
Ease of Use
4

Ease of Use

4/10

<p>ZoomInfo does not provide any kind of self-serve onboarding. Instead, it makes you jump through a series of video calls with sales agents just to trial the platform. Despite this, its search interfaces are familiar and intuitive to use. Additionally, profiles and company pages are well laid out, managing a vast amount of information well.</p><p>However, given the depth of functionality, some features were still not as intuitive as we'd like e.g. using its workflows automation feature. It would take an average SMB employee a full day to master the platforms use.</p>
8

Ease of Use

8/10

<p>Cognism's lack of functionality makes it simple and intuitive to use. Its core prospecting interfaces are familiar and easy to grasp. It would take an average SMB employee less than 10 minutes to master the platforms use.</p>

Ease of Use

8/10

<p>Much like their consumer facing product, LinkedIn Sales Navigator's web app is simple and intuitive to use. Its search interfaces are familiar and well presented. Additionally, its company profiles, though detail rich, are easy to navigate and use. It would take an average SMB employee less than 30 minutes to master the platform.</p>
7

Ease of Use

7/10

<p>Clay's web app is superbly designed and intuitive to use. If you're use to working with Excel and Google Sheets for your prospecting work, you'll feel right at home. That being said, the sheer depth of features may initially feel daunting and take some time to make the most of. It would take an average SMB employee an hour to master the platforms use.</p>

<p><span style="color: rgb(0, 0, 0);">Seamless.AI's relatively limited feature set means that its web app is relatively easy to navigate. Its prospecting interface is familiar, intuitive and well designed. It would take an average SMB employee less than 15 minutes to master its use. </span></p>

<p><span style="color: rgb(0, 0, 0);">Apollo's web app is intuitive and easy to navigate. Additionally, its onboarding was simple and not overwhelming.

Look and feel

Look and feel

4/10

<p>ZoomInfo has recently given many of its interfaces a facelift (most notably its core prospecting views). It's design aesthetic is modern, well laid out and intuitive. When tested, we also find its searches were very fast to load (often &lt;2s).</p><p>However, as a result of its depth of features, some screens remain clunky with features hidden in confusing places. Additionally, the 'home screen' is extremely cluttered and overwhelming.</p>
7

Look and feel

7/10

<p>Cognism's design is modern and relatively simple, especially when compared with a lot of its competitors. When tested, we find both searches and general interfaces to be fast to load. Additionally, contact profile pages and lists were well laid out and easy to consume.</p>
7

Look and feel

7/10

<p>Sales Navigator's design aesthetic closely mirrors that of its consumer counterpart (LinkedIn). When tested, we find its interfaces well laid out and able to display complex information in a way that still easily digestible. Additionally, we find that searches and page loads are generally fast to load (&lt;2s).</p>
8

Look and feel

8/10

<p>Clay's web app is modern, minimalist and well designed. When tested, we find its pages are very fast to load and whenever there are tasks that take some time to complete (e.g. AI agents doing web scraping), Clay's interface is clear and handles these scenarios well.</p>

<p>Apollo's web app is relatively simple and easy to navigate.

For example, its company profile view is cluttered with valuable information like recent news flow hidden in unintuitive areas.</p>
Customisability
8

Customisability

8/10

<p>ZoomInfo being an enterprise focused tool, is one of the most customisable products that we've tested in the sector. You can customise the layout of core screens such as the contacts and company tabs. You can also customise what columns are shown in search results when prospecting. Additionally, you're able to customise lead scoring algorithms, ICPs and much more to really tailor the setup to your needs.</p>
5

Customisability

5/10

<p><span style="color: rgb(0, 0, 0);">Cognism offers a handful of basic avenues for customisations. Beyond the ability to create custom searches or build targeted lists, you are also able to define an ideal customer persona to help hone and narrow searches more easily.</span></p>
5

Customisability

5/10

<p>Sales Navigator only offers a handful of avenues for customisation. Beyond the ability to simply create targeted lists, you're also able to create custom org charts to match buyers and champions within organisations. Additionally, you're able to create custom buying personas to more easily run complex searches. However, we noted the lack of some more enterprise friendly features, such as the ability to assign/manage territories to specific teammates.</p>
10

Customisability

10/10

<p>Clay is deeply customisable on a number of fronts. The primary channel is via its primary enrichment interface. The ability to add custom columns to tables to enrich lead lists with almost any datapoint you can imagine, is immensely powerful. Additionally, if a datapoint you're looking for is not natively integrated with Clay or cannot be scraped by its web agent, you can also take advantage of any external APIs with ease.</p>

Customisability

7/10

<p>There are a number of ways to customise your experience with Apollo, including basic channels such as creating custom lists, custom searches (which you can share with team mates) and defining criteria for lead scoring. There are also some deeper levels which you can customise such as providing the platform with context about your business and what you are selling - this information will then be used by their AI when drafting email sequences for example.</p>
Ease of Setup
1

Ease of Setup

1/10

<p>ZoomInfo is particularly difficult to get set up with. Frustratingly, they do not offer a self-serve option to try out the platform. Instead, you’ll need to trudge through two sales demos before you are able to access their trial and even a end of trial feedback call! Once access was granted, we found the platform simple to set up initially, however, there are a lot of details you’ll want to customise (such as personas etc.) let alone integrations with external platforms that can take a week to fully configure.</p>

6

Ease of Setup

6/10

<p>Customers are able to get started with Sales Navigator self-serve via their website. However, whether or not you get a free trial depends on your LinkedIn plan status e.g. premium, free etc. If you already have a LinkedIn account though, inital setup is extremely simple &lt;5 mins.</p><p>However, there are a number of things which you might want to customize that can take some time. For example, you are able to create buying heirarchy maps manually within the platform, something that can take several days to get the most out of.</p>

Ease of Setup

6/10

<p>Clay offers a self-serve free trial for their platform. Initial set up can be a little confusing though, given the novelty of their spreadsheets style user interface (taking &gt;15 minutes). However, their help centre and 'university' guidance centre is particularly well crafted which eases the burden in terms of getting the most out of the platform.</p>

<p>Unlike many of similar products of this scale, Apollo offers a simple, self-serve free trial for their platform. When tested, we found the initial setup to be simple (taking &lt;10 mins).

For example - most customers will still need to connect CRMs and customize Apollo's AI 'power-ups' to suit their needs.</p>
Customer Support

Customer Support

3/10

<p>When tested, ZoomInfo's primary method of support is via an account executive or sales agent. These agents, though helpful, often take over a day to respond and responses were often geared towards commercial goals rather than explicitly providing support. We were disappointed to see a lack of any kind of live chat widget embedded inside the web app. Additionally, ZoomInfo's help centre is one of the most overwhelming and hard to consume on the market.</p>

Customer Support

<p><span style="color: rgb(0, 0, 0);">You can contact Cognism's customer support via a live chat widget inside their web app. At first, you'll be greeted by an AI bot which, when tested, we find to be relatively unhelpful and eager to hand off to irrelevant help centre articles.

<p>The primary channel for support in LinkedIn Sales Navigator is via a chat widget inside their web app. The initial chat will be with an AI chatbot instead of a real agent.

How we test products

With so many Lead Generation platforms on the market, we focus on identifying the best options for small and midsize businesses. Our evaluation process reflects real-world usage, prioritizing functionality, ease of use, and overall value. Here’s how we do it:

Functionality

Lead Generation software should help sales teams find, analyze, and act on high-quality data. We start by identifying key use cases—lead enrichment, intent data, contact discovery, and predictive insights—then test how well each platform supports these needs. Tools that provide valuable insights without unnecessary complexity score highest.

User Experience & Onboarding

Sales teams need fast, intuitive tools. We test each platform’s interface by navigating core features without prior training and track onboarding time—from account setup to first data pull. Platforms that require complex setup or manual data wrangling lose points.

Data Accuracy & Coverage

The value of Lead Generation software depends on the quality of its data. We assess the accuracy, freshness, and depth of company and contact information, looking at factors like data sources, verification methods, and global coverage. Platforms with outdated or incomplete data lose points.

Integrations & Compatibility

Lead Generation software must integrate seamlessly with CRMs, Sales Engagement tools, and marketing platforms. We test how well each product syncs with key business systems, prioritizing native integrations over third-party connectors.

Pricing & Value

We compare pricing across competitors, analyzing what each plan includes and whether critical features are locked behind paywalls. Hidden costs—such as per-credit fees, add-ons for premium data access, or required implementation services—are factored into our assessment. Platforms that offer strong core functionality at a fair price score highest.

Stackfix’s Fit Score

All of these factors contribute to Stackfix’s Fit Score, a proprietary ranking system that measures how well each Lead Generation tool aligns with a buyer’s needs. It combines two key elements:

  • Requirements Met – How many buyer requirements the software fulfills
  • Stackfix Rating – Our expert assessment of the software’s overall quality, usability, and value

The result? A clear, data-driven recommendation that helps businesses choose the right Lead Generation software—without hours of trial and error.

FAQs

What is a Lead Generation Platform?

A lead generation platform helps businesses find, enrich, and engage with potential buyers more effectively. It provides sales teams with accurate contact data, real-time insights, and automation tools that streamline prospecting and outreach—allowing them to close deals more efficiently. The key features of a lead generation platform usually include:

  • Contact & Company Data Enrichment: Providing access to verified email addresses, direct dials, firmographics, and intent signals to help sales teams prioritize high-quality leads.
  • Advanced Prospecting & Filtering: Allowing users to search for leads based on job titles, industries, revenue, location, and behavioral intent—ensuring outreach efforts are highly targeted.
  • Sales Engagement Tools: Some platforms include built-in outreach automation for email, LinkedIn, and phone calls, enabling multi-channel engagement without switching between tools.

What should I consider when buying a Lead Generation Platform?

The right lead generation software can give your team a competitive edge by providing real-time insights, better prospecting, and smarter decision-making. But with so many options available, it’s crucial to find one that aligns with your sales process, integrates with your tech stack, and delivers real value. Here are the key factors to consider before making your decision.

  1. Your sales needs. Are you focused on cold outreach, account-based selling, or high-volume prospecting? Do you need verified mobile numbers for phone outreach, or is email accuracy your priority? Choosing a platform that aligns with your strategy will maximize ROI.
  2. Data quality & coverage. A database is only valuable if the information is accurate. Look at email deliverability rates, phone number verification methods, and geographic coverage to ensure the platform meets your needs. If your sales efforts are US-focused, some platforms may offer better regional coverage than others.
  3. Ease of use. A lead generation tool should make prospecting faster, not more complicated. Look for a clean, intuitive interface that enables quick lead discovery, list building, and outreach automation. That’s why Stackfix gives every platform an ‘Ease of Use’ rating—click into each product above to see how they compare.
  4. Integration with your tech stack. Does the platform sync smoothly with your CRM, sales engagement tools (like Outreach or Salesloft), and marketing automation software? Some platforms offer native integrations, while others rely on third-party connectors—make sure you check before committing.
  5. Pricing & scalability. Some platforms charge per contact export, while others limit access to premium features unless you upgrade. Consider hidden costs like API access fees, seat limits, and enrichment credits—and think about whether the platform can scale as your team grows.
  6. Customer support. Sales intelligence is mission-critical—so what happens if data syncing fails or a key integration breaks? Check for 24/7 support availability, response times, and self-serve resources like help centers and community forums.
