My Top 10 Seamless.AI Alternatives

After personally using different Seamless.AI alternatives, I’ve ranked my top pick based on their database size, data accuracy, user experience, unique features, and pricing plans. 

To help you make an informed decision, I’ve described each tool using a common format. 

For each tool, you’ll find a brief description of why it is a good alternative to Seamless.AI, a breakdown of its pros and cons, and its pricing information. 

Let’s go through the list! 

1. Saleshandy Lead Finder

If you’re looking for a Seamless.AI alternative that can help you find your ideal prospects and reach out to them—all from a single platform, then you can check out Saleshandy.

It has a vast in-built database (Lead Finder) with 700M+ professional contacts from 60M+ companies worldwide.

You can use the various advanced filters (demographic and firmographic) to narrow down and find your ideal prospects.

Moreover, compared to Seamless.AI, in Saleshandy, you can find prospects in highly niche industries and even within micro and small businesses.

After you have found your prospects, you can immediately reach out to them using Saleshandy’s advanced cold emailing capabilities.

Let me walk you through the pros and cons of Saleshandy.

Pros: 

• You can bulk-reveal up to 10,000 leads with just one click.
• A multi-step verification process that ensures 98% accuracy on A-grade email IDs. 
• Saleshandy integrates with CRM platforms like HubSpot, Zoho, Pipedrive, and Salesforce.

• You also get a complete suite of deliverability features to help make sure your outreach emails land in the inboxes of your prospects.
• It has flexible pricing plans tailored to the needs of SMBs, solopreneurs, and startups.

Cons:

• The trial period only gives you access to 5 free leads. 

Pricing (Billed Annually)

Saleshandy offers you two pricing models: one for just email IDs, and the other for both email addresses and phone numbers.

Lead Starter, the basic plan, starts at $24/month (only email addresses) and offers 1,000 credits for every month.

2. Apollo.io

Apollo.io is a sales intelligence platform with a database of 210M+ professional contacts and 35M+ company profiles. 

You get 65+ filters to narrow down and find the right leads that meet your ICP and prospecting requirements. 

For me, Apollo.io’s standout feature is custom lead scoring criteria, which lets you assign weight and variables to build a lead scoring model that suits your ICP. 

Overall, Apollo.io can be a great Seamless.AI alternative if you’re looking for a single platform for finding leads, multi-channel outreach, and managing deals. 

Here’s how Apollo.io worked out for me:

• Forever-free plan. 
• Tailored prospecting services for sales leaders, account executives, marketers, and founders.

Cons: 

• Mobile numbers are only available with the more expensive pricing plans. 
• Apollo.io’s credit system charges you separately for email IDs and mobile numbers, even if they belong to the same prospect. 

Pricing (Billed Annually):

• Basic: $49/UserMonth
• Professional: $79/User/Month
• Organization: $149/Month

3. Lusha

With 31M+ European and 155M+ US contacts, Lusha is your go-to Seamless.AI alternative if you’re looking for B2B prospects in the US and European markets. 

Lusha collects information from different sources and applies its compliance filter and AI algorithms to compile its GDPR-compliant database.

I’ve also noticed that Lusha has recently made two very big changes to its prospecting services. The first is its integration of AI into its lead finder: you can get AI-powered recommendations of prospects that match your ICP. 

Second, it has launched the Gen-AI Email Sequence feature, which helps you automate your outreach efforts and craft personalized emails using your value propositions to drive engagement.  

Here’s what I found when I used Lusha:

• Advanced Search features like funding and technology help you build highly targeted prospect lists. 
• Automated enrichment and CRM integration allow you to eliminate the problem of data decay. 
• Tailored prospecting services and pricing options for Small & Medium Businesses (SMBs).

Cons:

• Does not provide reliable B2B data on Asia Pacific, Middle East, and Latin American markets. 

Pricing (Billed Annually):

• Pro: $37/Month

4. Hunter.io

Hunter.io is a powerful email finder and outreach platform with a vast database of 117M+ verified B2B emails. 

Due to its flexible pricing plans, Hunter.io stands out to me as a Seamless.AI alternative for solopreneurs, SMBs, and startups. 

Hunter.io maintains a GDPR and CCPA-compliant database and offers you three ways to get your prospects’ emails: domain search, name search, and email verifier. 

In short, Hunter.io will do everything to help you build a prospect list that most closely matches your ICP. 

Here’s a recap of my experience with Hunter.io:

• The TechLookup feature helps you search for companies based on the tech stacks they use.
• Hunter.io comes with an advanced suite of cold email tools to help you initiate sales conversations.

5. Adapt.io

Adapt.io makes my list of the best Seamless.AI as the ideal option for SaaS companies. 

With a global database of 250M+ B2B contacts, Adapt.io gives you access to 16M+ decision-makers’ contacts and 12M+ company profiles. 

Here’s why I think it’s best suited to SaaS companies: with the “Adapt Tech Sector” prospecting service, you can find leads in specialized tech markets and niche industries. 

So, whether you’re looking for prospects in the tech marketing ecosystem or AI industry applications, Adapt.io will help you build a precise list of pre-qualified leads. 

Let’s check out its pros and cons:

6. ZoomInfo

ZoomInfo is one of the best enterprise-level Seamless.AI Alternative. It’s more than a prospecting tool: it’s an all-in-one marketing and sales intelligence platform. 

It boasts a database of 260M+ professional contacts, 100M+ company profiles, and 135M+ verified phone numbers from around the world. 

Plus, with ZoomInfo, prospecting is just the starting point: it also offers dedicated services to help you launch marketing campaigns, streamline sales pipelines, and attract the best talent in your industry.

7. Cognism

If you’re looking for a GDPR-compliant Seamless.AI alternative, I highly recommend checking out Cognism. 

It is a B2B sales intelligence platform that gives you access to 400M+ professional contacts and 10M+ company profiles across the EMEA, NAM, and APAC regions. 

Cognism is one of the best Seamless.AI competitors when it comes to direct dials. With Diamond Data, it gives you access to a vast database of highly accurate direct dials that are verified manually and by AI algorithms. 

In my opinion, Cognism’s strength is that it supplements prospecting with business intelligence to help you build a list of leads who are already open to buying your products and/or services. 

Let’s take a look at its pros and cons. 

Pros:

• CRM enrichment, CSV enrichment, and scheduled enrichment to help you prevent data decay. 
• Diamond Data: a database of 10M+ highly accurate direct dials. 
• In-built functionalities for marketing, sales, go-to-market, and recruitment operations. 
• Strong database for the European region with 200M+ B2B verified contacts.

Cons:

• Doesn’t provide data on the Latin American and non-US North American markets. 
• Cognism’s plans might be too expensive for startups, solopreneurs, or SMBs. 

Pricing:

Cognism offers customized pricing plans based on your requirements. 

8. UpLead

If you’re after a Seamless.AI alternative that specializes in SaaS B2B data, UpLead might be the tool you want. 

It takes a different approach to prospecting: with a relatively smaller database of 160M+ professional contacts and 16M+ company profiles, it promises an accuracy of 95%. 

However, I think UpLead’s strength lies in its tech-centric intent data. It tracks 16K+ technologies and lets you search for companies that use the tech stack you specialize in! 

Another thing that stood out to me is that UpLead verifies its contact data right before you download it, so you never have to worry about outdated information.

Here’s how UpLead stacks up as a Seamless.AI alternative: 

Pros:

• A Chrome Extension to help you scrap email and contact information from your browser. 

Cons: 

• Technographic and intent data is only available with the more expensive pricing plans. 
• Relatively low number of credits, even with the paid plans. 

Pricing (Billed Annually):

• Plus: $149/Month
• Essentials: $74/Month
• Professional: Custom Pricing

9. Lead411

Lead411 makes my list as the only B2B database that provides users with unlimited B2B data. 

It offers you access to a vast database of 450M+ professional contacts and 20M+ company profiles.

Lead411 uses an 8-step proprietary data collection process to provide you with highly accurate and verified contact information. 

One thing that caught my eye was Lead411’s  Cadence feature. It allows you to create “if this, then that” commands to automate your sales process and trigger emails based on real-time market movements. 

Let’s take a look at its pros and cons: 

Pros:

• Tailored prospecting services for SaaS companies, sales professionals, marketers, and recruiters.

10. Snov.io
