13 Powerful Apollo Alternatives for Enhanced Sales Engagement & Prospecting

Apollo (or Apollo.io) has been a go-to solution for many sales teams, thanks to its comprehensive suite of lead generation and sales engagement tools. With features like advanced search filters, automated outreach, and seamless CRM integrations, it’s easy to see why the platform is popular among businesses striving to streamline their sales processes.

But here’s the thing—no tool is perfect, and the platform might not meet everyone’s needs, prompting you to look for an Apollo alternative.

If you're looking for a more cost-effective option, need features that Apollo.io lacks, or simply want to explore other platforms, I've got you covered. This guide will walk you through the 13 best Apollo.io alternatives, breaking down their key features, pricing, and unique strengths.

How I Picked the 13 Top Apollo.io Alternatives

When selecting the best Apollo.io alternatives, I focused on several factors, including previous reviews, features, ease of use, and integration with other platforms.

Here are 11 tools that made the cut:

1. RB2B

RB2B leads our list of alternatives to Apollo by focusing on pinpointing the true decision-makers within target accounts rather than just company-level data.

Our platform delivers names, job titles, LinkedIn profiles, and verified emails of website visitors directly to your sales team via Slack or Teams. This eliminates guesswork and provides actionable intelligence for immediate outreach.

2. ZoomInfo

ZoomInfo is a heavyweight in the sales intelligence space, offering a comprehensive range of features that help businesses identify high-quality leads—you can read my comprehensive review of ZoomInfo here. It’s a top choice for companies that rely on rich data to drive their sales efforts.

ZoomInfo simplifies lead generation with features like:

• Advanced Search, helping users filter leads with precision
• Intent Data, highlighting prospects already showing buying signals
• Engage Analytics, tracking interactions and optimizing follow-ups
• Seamless CRM Integration, keeping data synchronized
• Instant Enrich, automatically updating contact information

In my experience, ZoomInfo was reliable for simplifying complex sales processes. While the platform presents a steep learning curve for new users, it becomes a powerful asset for lead generation and outreach once familiar with the tool.

Pricing

ZoomInfo’s pricing is tailored based on the number of users and features, but in my experience, it quickly becomes a considerable financial commitment, particularly for smaller businesses. While the platform’s advanced features are powerful, the steep prices can easily outweigh the benefits for teams operating on tighter budgets.

Pros 

• Extensive B2B database with advanced search filters
• Intent data to identify buying signals
• Robust CRM integration
• Real-time data enrichment
• Comprehensive lead tracking

Cons

• Expensive, especially for small businesses
• Steep learning curve
• Pricing not publicly disclosed

3. Clearbit (Breeze Intelligence)

Clearbit, now a part of HubSpot, excels in data enrichment and lead generation. It's a solid pick for teams that prioritize up-to-date CRM data.

Some of its standout features include:

• Enrichment API, seamlessly integrating with CRMs to provide real-time updates
• Prospector, identifying new leads based on ideal customer profiles
• Reveal, uncovering anonymous website visitors with deep engagement insights

One area that needs improvement, in my opinion, is the size of its data—with its 50 million company records, the platform feels limited compared to Apollo.io, which has 73 million. A smaller dataset will restrict the scope of your lead generation efforts.

Source: Clearbit

Pricing

• Free version
• Paid Plan: Starts at US$45/mo for 5000 credits

My gripe with Clearbit is that it doesn’t disclose its paid plans and prices. While the credit system may offer some flexibility, I found it insufficient since the credits would get depleted quickly!

Pros

• Real-time data enrichment
• Accurate lead scoring
• Seamless API integrations
• Detailed visitor insights

Cons

• Undisclosed pricing
• Few credits
• Small database

Here’s what LeadIQ offers:

• Identify, gathering leads from LinkedIn and other sources efficiently
• Email verification, ensuring valid emails to reduce bounce rates
• CRM integration, syncing data effortlessly for smoother lead management

For me, LeadIQ was INCREDIBLE for building and managing LinkedIn-based contact lists. However, I did notice occasional lags, particularly when working with larger datasets, which could disrupt workflow, a testament shared by other users.

• Real-time email verifier, ensuring lists are up-to-date and reducing bounce rates
• Data enrichment, adding valuable information to existing contacts for targeted outreach

I’ve found UpLead to be a consistently reliable source of accurate contacts. While its dedication to ensuring data quality is impressive, it can sometimes fall short in niche markets. Occasional technical issues could be another downside of the platform.

• Chrome extension, making it easy to extract leads directly from LinkedIn

While I’ve found Lusha effective in syncing contact data with CRMs, its smaller database of 45 million contacts can be limiting for larger-scale campaigns, especially when compared to Apollo.io’s 275 million. That said, its ease of use and LinkedIn focus more than compensate for these limitations, making it a dependable option for targeted outreach.

Seamless.ai offers:

What I most enjoyed about the platform was how it incorporated real-time data into my campaigns, which made a HUGE difference in how quickly my team could reach the right contacts.

Final Thoughts

After exploring alternatives to Apollo, it’s clear that the right tool for your business depends on your specific needs and priorities. ZoomInfo stands out as a strong contender if you require a comprehensive database and advanced search capabilities. However, its steep pricing might be a barrier for smaller businesses. 

I do have a few tips to offer to help you identify the ideal GTM solution for your business:

• Assess your budget: Compare the pricing of these tools to find one that fits your budget without compromising essential features
• Consider your data needs: Evaluate the size and accuracy of each tool’s database, especially if you require niche market coverage or specific industry insights
• Prioritize integration: Ensure the tool you choose seamlessly integrates with your existing CRM and other platforms to maintain workflow efficiency

Regardless of the platform you choose, I recommend leveraging complementary tools to maximize your lead generation efforts. One such tool that has significantly improved my own sales process is RB2B’s Person-Level Website Visitor Identity tool. It’s a simple, 100% FREE solution that delivers detailed visitor profiles directly to your Slack channel, enabling you to engage with high-intent leads quickly and effectively.

How RB2B Can Help You Get More Leads

While platforms like ZoomInfo and Clearbit provide valuable data, they typically focus on company-level insights. This can leave you with the task of identifying the key decision-makers within those companies.

That’s where RB2B comes in—it bridges this gap by providing personal-level lead data, helping you directly connect with the individuals who matter most.

Here’s how it works → RB2B identifies visitors to your website and sends their complete profiles, including name, job title, company, LinkedIn profile, and email address, straight to your Slack channel. This information also includes the specific pages they visited, giving you insights into their interests and intentions. With RB2B, you can approach potential leads with tailored, relevant outreach, improving your chances of conversion.

And yes, it’s fully compliant with CCPA and CPRA regulations—since it focuses solely on U.S.-based traffic, GDPR isn’t applicable here.

Getting Started With RB2B

Getting RB2B up and running is straightforward—here’s what you need to do:

1. Sign up on the RB2B website
2. Confirm your email address and provide the required information
3. Install the RB2B script in your website’s header
4. Integrate RB2B with Slack and enable real-time alerts

The basic version of RB2B is free forever! If you want additional features like advanced filtering, CSV downloads, and integrations with other apps—including Apollo.io—you can try the Pro version free for 30 days.

If you’re looking to enhance your lead generation strategy, RB2B’s Person-Level Website Visitor Identity tool is a MUST-HAVE booster that complements any sales platform by providing instant, actionable insights.
