Seamless.ai vs ZoomInfo – Which is Better and Why?

When considering a purchase between Seamless.ai vs ZoomInfo, there are a few factors to consider such as features, integrations, and pricing. There’s also a free trial which is a great way to sample the product.

What is ZoomInfo?

After over 20 years of business, ZoomInfo has become one of the most trusted brands in the subscription-based, software as a service (SaaS) and B2B marketing industries. ZoomInfo’s business model is built around their contact database, offering users access to their lists of individuals and companies across the globe. ZoomInfo employs the use of artificial intelligence (AI) and machine learning (ML) to connect users with the contacts that will be most valuable to their efforts. ZoomInfo displays a sizable database, which includes over:

  • 100 million company records
  • 150 million contact records
  • 50 million direct dials
  • 41 million mobile phone numbers
  • 129 million email address

According to ZoomInfo, all of their contacts are voluntary contributors, meaning that they have willfully agreed to being featured in the database. This is a huge plus for individuals working on sales teams, as cold calling is difficult enough without having an unwilling participant on the other end of the line. ZoomInfo’s contact database is regularly updated via automated machine learning, which does so by scanning outside sources, such as news articles, corporate websites, job postings, SEC filings, and more.

Though ZoomInfo’s website states that their contacts are global, the bulk of their information is centered around contacts in North America, followed by those in Europe.

ZoomInfo’s database is massive, but that does mean that the software comes with a higher price tag, though there are options to access a smaller amount of their contacts for a cheaper price. Either way, this wellspring of data is an invaluable tool for those working in recruiting, marketing, and sales at large companies that are looking to make connections with large, big ticket contacts that fall into the mid-market range or above. The larger the company, the more information ZoomInfo’s database contains about them, meaning that smaller businesses may not have as much detail.

What Is Seamless.ai?

Seamless.ai is a relative newcomer in the B2B market, but its low prices have begun to attract a number of small businesses. It operates similarly to ZoomInfo in the sense that it has a contact database that is available to its customers, but describes itself as a “business research tool” that offers its data for business research rather than making sales. It is estimated that Seamless.ai has a database that features roughly 800 million contacts.

As the company’s name suggests, Seamless.ai uses artificial intelligence to present its users with professional information that is directly relevant to their business, identifying the most useful or profitable connections based on a company’s past and present profile.

Unfortunately, Seamless.ai does not display all of their company information in a way that is as readily available as some of its competitors, which can be a detriment as potential users do not know exactly what they are getting into. To bypass this, users can create a free account to peruse the website and its features and earn “credits” for completing certain activities. These credits can go toward making contact searches through Seamless.ai, meaning that a user can potentially use the service for free — almost like a free trial — but will have to upgrade their account once they run out of credits.

Finally, Seamless.ai is considered to be easy to use, as users on G2 gave the software above average scores in the Ease of Use, Quality of Support, and Ease of Setup Scores.

Seamless.ai vs ZoomInfo Features

In addition to their contact databases, ZoomInfo vs Seamless.ai offer extra features that can benefit its users in a number of ways. These features can be customized to fit the individual or company’s needs, whether it be in recruiting, sales, or marketing.

ZoomInfo offers its subscribers a number of features in order to maximize their efficiency and effectiveness while using the software. Keep in mind, some of these features are not included with a standard ZoomInfo subscription and may cost more. Here are some of the best additional features ZoomInfo has to offer:

Buyer Intent

ZoomInfo’s artificial intelligence and machine learning offer the unique ability to potentially gauge a contact’s buyer intent. ZoomInfo uses what they refer to as the “intent engine” to recognize and analyze patterns and notify sales teams which contacts are ready to buy and when.

ZoomInfo Engage

ZoomInfo Engage is a sales tool that has the ability to automate phone calls and emails, which is a plus for sales teams that have a large client and contact base. ZoomInfo Engage is technically considered an integration and does come at an additional cost, but the price is worth it when compared with the time that could be saved with automation.

Conversation Intelligence

ZoomInfo’s Conversation Intelligence is another feature that takes advantage of the service’s artificial intelligence capabilities. It captures and analyzes calls, emails, and meetings that users conduct between themselves and customers, putting the information discussed in an easily understandable format.

Seamless.ai does not have much information about their useful features on their website, which could be a tactic to encourage potential users to sign up for the software in order to learn about it themselves. Like ZoomInfo, Seamless.ai uses artificial intelligence and machine learning to inform decision making, but takes it a step further by centering the majority of its functions around AI. Here are some of Seamless.ai’s best features:

Chrome Browser Extension

Instead of solely operating in a separate window, Seamless.ai offers the unique ability to add the software as a browser extension for Google Chrome. This is useful when browsing LinkedIn or company websites, as the Seamless.ai browser extension can quickly gather relevant data about the company or individual from their web page.

Lead Enrichment

While nearly all B2B database software services regularly update their contact information, usually on a month-to-month basis, Seamless.ai does more than just updating pre-existing data. Instead, Seamless.ai’s Lead Enrichment feature uses artificial intelligence to learn more about a specific contact, plucking specific data from the internet about that individual or company and adding that new, relevant data into the contact’s information, allowing users to be better informed.

Lead Analysis

Lead Analysis is Seamless.ai’s most invaluable feature, as it uses artificial intelligence to deliberately select and present contacts to its user. This selection is based on lead scoring and market interactions, analyzing patterns, and comparing the contact’s data with that of the user,  in order to determine whether or not this connection would be beneficial to the user. This is a crucial feature, as it does not force subscribers to search for their own leads and saves them time.

ZoomInfo vs. Seamless.ai Integrations 

When considering Seamless.ai vs ZoomInfo, it’s important to remember that software needs to work well together. Almost every company uses multiple types of software to assist with their day to day functions, so it is essential that each one of these programs can function well with another and communicate. Additionally, there are a wide range of business-based programs and no two companies use the same combinations, meaning that software needs to be able to accommodate all of these options.

Seamless.ai and ZoomInfo both have a wide range of compatible integrations, making it easy for users to have every tool they need to be as efficient as possible. It is important to note that many of these integrations are not included within the ZoomInfo or Seamless.ai software and may have an additional cost. Employing multiple subscription-based software can be pricey, so it is paramount that companies choose wisely when selecting new programs to ensure that they work well with their other programs.

ZoomInfo offers a large number compatible integrations, from the most popular software to programs that are not common, including many of ZoomInfo’s own integrations:

  • Salesforce
  • HubSpot CRM

This means that Seamless.ai has the highest number of compatible integrations amongst its competitors, which can be useful for users who employ unorthodox programs. Here are some of Seamless.ai’s most popular integration options:

Seamless.ai vs. ZoomInfo Pricing 

Especially for small businesses or start-ups, price may be the deciding factor when it comes to choosing between ZoomInfo and Seamless.ai. Both services function using tier-based pricing in order to cater to a wide range of customers. The smallest packages are cheaper, but offer less, while the larger packages are far more expensive but give the user access to more features.

The more popular of the two software services, ZoomInfo offers three different tiers: professional, advanced, and elite. Each package comes with its own customizable features with corresponding price tags. Because of the varying options for every business, ZoomInfo does not display a set cost for any of these packages, and pricing reports range anywhere from $6,995 a year for the professional tier to $44,995 for the elite tier.

Seamless.ai proves to be a much cheaper alternative to many of its competitors, depending on the package selected. It currently has three price tiers: Basic, which is priced at $250 a month for a single user; Pro, which costs $1,000 per day, per user, but allows up to five users; and Enterprise, which has no set price and potential users must ask for a quote.
