Seamless vs. Wiza: Complete Comparison for B2B Contact Data

No matter which industry a sales professional is in, they are familiar with the complexities of modern prospecting.

The tools. The processes. The tracking. The techniques. The expectations. The rewards.

It's not fun when you've got completely digital businesses, changing contact info, and market oversaturation making it difficult to determine what is reliable, relevant prospect details. 

That’s why many B2B sales teams rely on advanced B2B providers for prospecting tools that stay on top of the most accurate, up-to-date information, like phone numbers, email addresses, and other key company data.

Seamless and Wiza are two those choices for B2B prospecting buyers. How do they compare? Which is the right choice for your sales team?

Below, we take a layered approached into Seamless vs Wiza across data quality, enrichment capabilities, and more to determine which is best prospecting tool for you.

Overview of Seamless vs. Wiza

Wiza is a relatively new B2B prospecting tool that puts a heavy emphasis on generating LinkedIn leads. It claims to solve the problem of outdated, inaccurate contact data with live updates as it scours records to deliver prospect details

Wiza is primarily aimed at Small and Medium Enterprises (SMEs) hoping to power their pipeline with:

• More access to B2B contact info
• Improved monitoring of prospect development and movement along the buyer’s journey
• Integration into key platforms and programs (especially for organizations that rely heavily on LinkedIn for leads)

While Wiza claims to be the most accurate B2B prospecting tool and the only platform that checks data in real-time as you request it, other solutions offer similar features.

Seamless is a more established with 3x more 5-star reviews on G2, and proven prospecting tool that never stops searching for new, enriched contact data. That means client details are as fresh (or even fresher) than Wiza’s, offering team leads and account managers clarity, peace of mind, and certainty during outreach. 

Seamless is a robust, multi-faceted prospecting tool that reaches beyond LinkedIn to find contacts wherever you search for leads. It offers a massive database, key automation features, and smooth workflow integrations to reduce manual work during prospecting and deliver informed, viable leads.

Core Features Compared

When deciding between Seamless vs Wiza (or any other B2B prospecting tool), one key feature to look out for is access to contact data. 

Expanding your lead potential is essential for building your pipeline. That’s why Seamless offers information on 1.3 billion validated contacts. Seamless also finds more than just the basics, like industry and phone number, to deliver data across over 100 critical points, such as:

• Years in business
• Company legal structure
• Customers
• Products
• Growth trends
• Tech stack
• Socials

In comparison, Wiza’s databases hold 830 million contacts (mostly harvested from LinkedIn), less than two-thirds the reach of Seamless. While Wiza does support filtering by contact characteristics, it collects details across fewer than 20 data points, leading to less targeted outreach and segmentation.

Seamless has a wider data collection practices, which means more opportunities for contact enrichment. Seamless automatically identifies and automates enrichment opportunities to update information across its database and your integrated contacts. Seamless never stops searching because business details are constantly changing. 

Wiza supports AI-based enrichment, but requires you to select which contacts you want to update and improve, rather than automatically searching for new information for all entries.

Seamless’s wide reach also extends to available integrations. With thousands of native and Zapier-based integrations, you can connect nearly any program with Seamless for smooth, uninterrupted workflows. Wiza supports a similar range of integrations, though it focuses heavily on its functionality with LinkedIn.

Despite their differences in data depth and enrichment capabilities, the debate between Seamless vs Wiza primarily comes down to data accuracy. Without the right contact information and sales playbook, your leads result in dead ends. 

So, which platform offers more reliable, accurate data?

Email and Phone Data Accuracy

Seamless constantly checks your data against its ever-expanding roster. Round-the-clock updates ensure your client log always has the most accurate and complete records available. 

Wiza’s monitoring features allow you to search for updated contact information, but they’re not as robust or automatic as Seamless’s. To update contacts in Wiza, you need to create a list of all the entries you want to monitor for new information. Once new information is available, you’re notified to download the data to your own records. 

Unlike Seamless, the process isn’t fully automatic, making the experience more tedious and ripe with the opportunity for human error.

LinkedIn Prospecting Capabilities

The Seamless Chrome extension simplifies prospecting on LinkedIn. Instead of being limited to a user’s publicly available profile information, Seamless Chrome extension lets you:

• Preview the contact’s Seamless profile, including titles, emails, and phone numbers, directly in the sidebar.
• Sort LinkedIn connections into targeted lists based on industry, place in pipeline, and other factors.
• Find contact information for entire lists of users and then automatically save it to your Seamless database.
• Engage directly with contacts through emails, messages, or calls, or add them to a Seamless Connect campaign.

Wiza’s browser extension offers similar features, allowing you to view and download user contact details from LinkedIn profiles. You can also sort contacts into lists, export information to other platforms, and perform outreach with the given information.

While it boasts similar functionalities to Seamless, Wiza’s interface is slightly clunkier. It exports email lists as .txt files and requires switching programs to perform outreach, giving Seamless the edge for ease of use on LinkedIn.

Ease of Use and Integrations

Seamless’s User Interface (UI) is easy to navigate. With simple, intuitive features, you can view contact details, sort client lists, generate outreach content, and more without bouncing between multiple programs. Seamless also consistently updates its UI for ease of use and visual clarity. 

Wiza’s UI is also relatively clean and functional, with essential features laid out clearly and easily accessible. 

When it comes to onboarding, Seamless offers an entire support section focused on getting started. While Wiza hosts a variety of questions and answers on its support page, it’s not as straightforward when it comes to initial setup and use.

As noted, Seamless and Wiza are relatively balanced across integration potential. Both offer thousands of connections through Zapier, and each boasts its own native integrations for popular CRMs and tools.

While Seamless takes the cake for ease of use, which prospecting tool earns the title of Best Value?

Pricing and Value

Seamless’s free tier offers 1,000 annual credits per user, which you can put toward contact lookups and content generation. You can always purchase more as your pipeline and customer base expand.

The Pro and Enterprise packages give you extra capabilities, including:

• Data enrichment
• AI assistance
• Buyer intent data
• Autopilot for outreach automation
• Live chat support

With the Enterprise plan, you also get a dedicated success manager, quarterly business reviews, and phone support. All Seamless paid plans feature custom pricing, meaning you only pay for the services and features you need, rather than those you don’t use.

Wiza also offers a free model with an associated credit system. However, you’re limited to just 25 credits off the bat (redeemable for 20 emails and 5 phone numbers). Beyond this, you’ll have to pay, and Wiza doesn't necessarily come at a low cost:

• Starter – For $49 a month, you can access up to 100 phone numbers and emails.
• Email – 500 email addresses per month costs $99 (no phone numbers included).
• Email + Phone – For $199 a month, you can access 500 emails and phone numbers.

Outside of your monthly allowance, each email costs $0.15, while a phone number will run you $0.35. If you want unlimited access to contact information, you’ll need to sign up for the Team Plan (starting at $449 a month) or lock into an extended contract. Even then, Wiza’s “unlimited usage” is capped at 500 contact reveals per day, or 50 in five minutes.

Seamless scales to meet your needs. The Enterprise package supports unlimited users and unlimited exports with no caps or limitations. Wiza’s Team Plan only supports three users, though you can negotiate a custom package if you want to add more. 

Importantly, purchased credits on Wiza don’t roll over to the next month, meaning you have to use them in 30 days or watch them expire.

Pros and Cons of Each Platform

Seamless offers a variety of advantages over Wiza, including:

• A larger contact database
• More automation features for information updates, enrichment, and content generation
• More data points to track and filter

• Higher scalability

On the other hand, Seamless’s pricing structure is less transparent than Wiza’s, so you’ll have to contact sales to get an accurate quote. 

Wiza offers clearly defined pricing tiers, but falls short on:

• Automation, as it offers fewer overall features.
• Database size, which is only about two-thirds that of Seamless.
• Try before you buy options, with only 25 contact reveals before you have to purchase credits.
• Scalability, as its top plan only reserves space for three total users.

Which Tool Should You Choose?

No matter your team size, outbound needs, or budget, Seamless offers more features with less hassle and cost than Wiza. 

If you only prospect on LinkedIn, Wiza may be a viable choice, thanks to its close integration with the platform and its ability to crawl its resources. Its database, after all, is primarily populated via publicly available LinkedIn info. Unfortunately for Wiza and similar tools, LinkedIn recently banned the practice of contact scraping.

Seamless is the optimal choice for versatility, scalability, automation, and more. With a wider reach and more intelligent features, it's the only B2B prospecting tool you need to power your pipeline, maintain your growth mindset, and land more conversions.

Seamless vs Wiza: The Final Verdict

The debate between Seamless vs Wiza boils down to a single question: Which better supports your prospecting potential?

With a larger database, more features, easier automation, and higher scalability, Seamless is the essential B2B prospecting tool for businesses of all sizes.
