The Ultimate B2B Data Provider Market Overview (+ Side-by-Side Comparison of 55 Tools)

The Ultimate B2B Data Provider Market Overview (+ Side-by-Side Comparison of 55 Tools)

Every sales team runs on data. From prospect information to buyer intent and engagement metrics, having the access to up-to-date, valid data (and making a good use of it) is crucial to your revenue growth.

On the other hand, corrupt or stale data – or lack thereof – can impair even the best sales team.

That is why it’s so important to choose the right data providers. 

We’ve been there and know first-hand how many options are available and how hard it is to pick the best one. We’ve even built our own contact database to solve this problem (we’ll get there).

So in this post we will explore the current state of the B2B data provider market, review the most popular tools, and provide some actionable recommendations to help you make the right choice.

Where do SDRs get B2B prospect data?

People tend to be very protective of their personal data. While business emails or other professional details can’t be considered sensitive information, it’s still relatively hard to get ahold of it.

Generally speaking, there are just two ways to get B2B prospect data: 

  • Manual research

There are many ways to find anyone’s email or practically any other contact information online. 

If you know who you’re after, you can look up their info on Google, social media, or their company website, make an educated guess using common patterns, or use various email finder tools

The latter offers a perfect mix of manual sourcing and automation, offering a fast and convenient way to find prospect information, especially if there’s a bulk search option.

In my experience, manual research allows you to build high-quality, targeted lists with accurate data (since you get to double-check every detail you find). However, it is also a time-consuming task requiring more than a little ingenuity. And even if you use free tools, you can’t call it a cost-effective approach given all the time you or your team spend on it.

  • B2B database

Data providers offer a faster, more convenient way to source prospect contacts. Simply put, they aggregate the available information in one place, making it searchable and easy to navigate. This information can include anything from an email and phone number to business revenue, technographics, and even certain intent signals associated with each specific account.

The data is usually pre-verified and segmented by industry or other filters, which makes it easy to create targeted lists at scale.

Yet, building and maintaining such a B2B database isn’t an easy task. As a result, many contact databases are getting stale and the information – outdated or invalid. That is why you should always make an extra investment to validate the data (on top of the already high cost of the data).

Sidenote: You can also choose to get your data from a vendor – usually an agency – that will do all the work for you. However, the agency sourcers will still either do manual research to look up the right contacts or use some sort of contact database (their own or a third-party’s).

What to look for in a B2B data provider?

The B2B database market is very versatile. There are dozens if not hundreds of different tools ranging in size, price, focus, and many other features. 

So, before we talk about specific data providers, let’s do a quick market overview to identify some common or distinctive capabilities you should be looking for in a contact database.

1. Data attributes

The main function of a B2B data provider is, well, to provide businesses with relevant business data on their prospects. So the first thing you should look into when evaluating the potential data providers is the size, completeness, and quality. 

  • database size – meaning the number of contacts you can get (and, as a result, your potential reach) is very important. What’s more, you should also consider the geography of the data, if you target prospects outside of the US. 
  • available information, from personal contact data (email addresses, phone numbers, social links, even addresses) to job-related details (company, department, role).
  • data quality – in other words, its accuracy and validity (or built-in validation capabilities). This will directly impact your delivery rate and sales outcomes in general.   

Note: Don’t be fooled by the numbers you see on the landing page. The biggest database isn’t always the best choice. Consider all of these data attributes in total to pick the right provider. 

2. Specialization

As mentioned above, a B2B database can contain different types of data. Yet, there are also providers that specialize in certain information, for example:

  • Contact data – exhaustive contact and personal information about your prospects and accounts (companies) in general.
  • Firmographics – information about a company, from industry and headcount to funding or acquisitions (Owler, Vainu)
  • Technographics – the tools and technologies a business is running on (BuiltWith)
  • Psychographics – insights in the prospect’s personality (Crystal)
  • Intent data – like research signals or website visits (G2, Leadfeeder)

All of this information can be extremely valuable in sales prospecting, so it’s up to you to choose the provider that better fits your needs. But there are more things to keep in mind when making this choice 👇.

3. Pricing

This is the most important and most difficult part of the data vendor evaluation process, especially considering the complex (and often undisclosed) pricing options they offer. While the budgets may vary, I will leave the choice up to you. But there are a few things to keep an eye on.

First of all, review the available pricing plans and their terms, including the number of seats/team, search credits/month, as well as the required minimum commitment. Different teams might be looking for different terms. For example, usage-based pricing is a great choice for startups while enterprise teams could go with fixed plans. 

The free/freemium option is a nice way to test the waters or for those of you looking for a quick and dirty way to build a smaller list.

Note: It also makes sense to know the cost per 100 contacts to calculate the sales ROI you could get from this tool. This will also allow you to understand if this option is scalable and feasible in the long run. 

4. Additional features

It’s said that an average sales stack contains around 10 tools. But the number is increasing as more sales software categories emerge on the market. As a result, many sales teams try to optimize their budgets choosing complex, all-in-one solutions or at least tools that combine a few key features.

As for the B2B data providers, there are several additional features they may offer as a part of the package.

  • Sequencing capabilities for sales engagement. This may be limited to emails or cover other channels as well (calls, social, messengers). BTW, it’s also one of the recent sales tech trends for email finder tools to introduce some sort of email sending as a hybrid solution.
  • Intelligence/AI features can help you better tailor your ICPs, get extra insights into your audience, or even prequalify the prospects using intent data. In the case of AI, it can enrich your buyer persona based on certain patterns or use its algorithms to provide you with custom-built lists.
  • Data enrichment allows you to get some extra data points for the existing records in your CRM. So, rather than hand-picking new prospects, you can discover more information about the ones you already have on your list (inbound or outbound).
  • Data validation is a crucial element of your deliverability toolset. Of course, you can use a third-party tool to verify your data, but having it as a part of the package (rather than moving data back and forth between the tools) could be a nice option.

On top of that, many data providers also offer Chrome extension or a lightweight addon – usually an email finder tool to use on the go. These can help you discover prospects anywhere on the web, especially on LinkedIn, or have all the information about your prospects right in your inbox. While it’s not as important as, for example, validation, it can definitely make your life as an SDR easier.

5. Integrations

If you don’t want to limit your choice of a B2B data provider based on the extra features they provide, at least make sure the vendor integrates with the rest of your stack. There are at least two must-have tools that any contact database should integrate with: a customer relationship management platform and a sales engagement platform. Being able to sync the data you get from the vendor to your CRM or your SEP directly – rather than exporting and importing the CSV files – will save you a ton of time and effort. 

I would recommend you go with native integrations when building your stack. In this case you can rest assured that your data will move smoothly across your toolset. 

However, there are also other integration options that you can explore, including tools like Zapier or Integrately. In this case, you can build a no-code bridge between your data provider and practically any tool in your stack and automate not just data synchronization but also certain processes.

Note: Some tools also offer an API so you can build your own integrations. This option, however, isn’t always easy or free and will require some technical efforts.

Overview of the top B2B data providers on the market

Considering the growing adoption of sales engagement and automation tactics, the B2B data market is thriving. There are dozens of tools available, ranging from niche solutions to  industry leaders and from lightweight email finders to rich databases containing hundreds of millions of contacts.

Analyzing each of the available options would take too long, so we’ve made this brief overview table highlighting the most important aspects of each tool.

Now, I’d like to focus on B2B databases specifically – the most popular and the largest. Here are my top 10 picks with a more in-depth analysis.

Reply Data

Most of my professional life as an SDR I’ve been a sceptic when it came to B2B data providers. I’ve always preferred manual research, coming up with creative tactics to find business leads and trying to automate certain parts of the list-building processes.

This eventually led us to develop our own database to fuel our prospecting efforts with high-quality, relevant, and affordable contact data. And just recently we’ve decided to make it available to Reply users. Let’s break down its unique selling points.

First and most importantly, it contains data we’ve sourced internally; it’s not just a purchased list. There’s currently just over 100 million contacts, mostly covering the US and European audience. You can fine-tune your search using 10+ filters and source contact info (name, email, phone, and LinkedIn profile) as well as full firmographic data.

We verify the data internally and mark the contacts accordingly so you know if the email is safe to use (or simply filter out just 100% valid contacts). However, you can also double-check the data using our validation feature. 

Secondly, it’s integrated into our core sales engagement platform, which makes it an all-in-one tool. From building a list to booking meetings – you can do all of that without leaving your Reply account.

But the best part about it is that Reply Data is 100% free to use with 10,000 monthly email search credits (per organization). This makes it a perfect choice for small-medium teams working with laser-focused lists.
