Briefly, a B2B contact database is a set of data and contacts of private and public companies and the individuals working in those companies gathered in a consistent database used as a business reference primarily for lead generation.

Determining the best B2B contact database providers is subjective and can vary based on specific needs, but some popular options include ZoomInfo, DiscoverOrg (now part of ZoomInfo), LinkedIn Sales Navigator, InsideView, (now part of ZoomInfo), and UpLead.

These individuals may be simple employees or employers, CEOs, and decision-makers of companies and organizations. The recorded companies usually include both private and public ones. However, the data comprehensiveness of B2B contact databases depends directly on their quality and the AI technology they use.

Where to use a business contact database?

B2B data providers usually provide the names of companies and the individuals working in those companies, plus their contacts. By contacts, we mean their emails, phone numbers, domains, social media profiles, etc.

Even some of them provide some other interesting data like the No. Of employees of companies, individuals’ interests, job titles, job summaries, etc. It totally depends on the innovation level of this database!

However, all B2B contact business databases are not the same. The more contacts and data a database provides, the easier your job as a marketer will be, the faster connecting with customers will be, and the more benefits will return to you.

Prospecting and lead generation happen faster and easier by using this data and contacts unless the quality of the given information is low!

You can easily send emails to many leads’ email addresses or call them directly through their phone numbers. You can visit their websites to check their backgrounds and achievements or directly send a message to their social networks like LinkedIn.

The more data a B2B contact developer gives, the more channels are opened for you to connect with leads.

In this article, we will introduce all contact databases on the web. Still, it is necessary to know what features a perfect data provider of companies and leads should have before introducing all available databases. Then finding the best B2B contact database in the market is easier for you.

How to recognize the best online company contacts database?

Complete: The B2B contact database you choose should be comprehensive. The more data recorded in it, the more channels of connecting with prospects are available. Emails, phone numbers, and domains are not enough. Choose the one with at least the companies’ social media URLs too.

Employees & employers: Try the database, which has the data and contacts of companies and their leads, including employees and employers.

Verified data: Just trust the one which checks the accuracy of all contacts and the extracted data with the help of artificial intelligence. Verified contacts greatly speed up the lead generation process, connect with real prospects, sign contracts, and finally achieve the predetermined targets.

Rapid: You need a service that can extract the data of companies and leads from its database in the shortest possible time. You use an online database to speed up the lead generation process, so waiting a long time for the results is awful!

Up-to-date: A B2B contact database that does not update its recorded data daily, weekly, or monthly is not valuable enough to trust. Outdated emails increase your bounce rate, and outdated phone numbers just increase your telephone costs! It’s better not to forget its time-wasting too!

Price: The prices of marketing services are always essential for any company, especially SMEs and startups. But remember that if you find a very high-quality and precise B2B contact database, don’t take it hard! Some databases are really worth paying more money for.

The rest of this article introduces all online B2B contact databases of the market through which you can extract businesses’ data in bulk and in real-time.

Their upsides and downsides are all mentioned based on the reviews of people and marketers that have been published on the web.

It has a comprehensive and complete B2B contact database through which getting accurate and full data and contacts of companies and individuals is no more a dream!

What data has been recorded in the CUFinder business contacts database?

  • It has recorded the data and contacts of companies like the companies’ names, websites, social media profiles, emails, phone numbers, revenue, industries, addresses, summaries, logos, and so many other interesting data.
  • Also, the complete contacts and data of companies’ individuals, from their simple employees to decision-makers, have been gathered in CUF.

How to work with CUFinder B2B contact database?

  • To get the data of companies, you should select 5 various filters including industry, location, revenue, No. employees, and products/services. Then based on the filters you have chosen, CUF provides the contacts and data of companies.
  • To get the data of leads, you should select 8 filters offered by CUF including industry, location, job title, interests, No. of employees, companies’ domains, revenue, companies’ products/services. Then based on the chosen searching criteria, the list of individuals’ names and data are given.

Of course, in both cases, the more filters you choose, the more relevant data will be given. So try to narrow down the results as much as possible by determining more filters unless you really need a wide range of information.

Based on your chosen filters, the result may include a small amount of data or a huge one.

Suppose you ask for the data of all American companies active in the IT industry. In that case, the result is much more than the time you ask for the data of the marketing agencies registered in Adelaide city of Australia, which have less than 10 employees.

In the first example, only 2 filters of location and industry were active, and the chosen country was also a big and populated one. In contrast, 3 filters were selected in the second example, including location, industry, and No. of employees. Also, the chosen location was a city with less than 1.5 million residents!
