In today’s vast marketplace, connecting with leads can feel like chasing shadows.
LinkedIn profiles are rarely updated and website contact details often go out of date. In fact, it has been estimated that 70% of the data you have in your CRM will become inaccurate annually, leading to your emails bouncing and phone calls going unanswered.
That’s why your business needs a B2B contact database—a regularly updated repository of contact details and data on all your potential leads.
But with so many B2B data providers on the market, where do you start?
We’ve researched 12 of the best B2B data platforms to help you choose the right one for your business. But before we get into it, let’s talk about B2B data.
What is a B2B contact database?
A B2B contact or B2B leads database is a list of contact details businesses use to reach leads.
Contact databases traditionally contain information like:
Addresses
Phone numbers
Email addresses
Social media profiles
Company headcount
Financial details like revenue
Your company can compile B2B contact data through networking and research efforts.
But for modern businesses, succeeding in today’s fast-paced, hyper-personalized marketplace requires a more comprehensive solution.
B2B database providers offer that solution. Tools like Dealfront offer extensive B2B lead lists containing both contact details and additional data, such as:
Historic data: This might include a company’s previous interactions with you. For example, a business might have signed up for an email newsletter, trialed your products, emailed your team with inquiries, or even made a purchase. Having this data on hand allows your sales and marketing teams to score B2B sales leads and develop deeper relationships with potential clients.
Deep insights: B2B data, such as behavioral, technographic, psychographic, and firmographic data, allows you to better understand your leads. This gives your sales and marketing teams a way to personalize outreach based on a company’s budget, ethics, past behavior, culture, location, and specific pain points. It also provides a way to analyze patterns and trends that indicate conversion likelihood.
A company’s key decision-makers: It’s one thing to know who to contact; you also need to know details like their phone numbers, email, and social media accounts. This data helps you reach out to the right people through the most effective channels.
Sounds like a handy tool, right? So how do they work?
A B2B sales leads database scrapes publicly available data from across the web—from LinkedIn profiles and company websites to Google business data and beyond. The provider can also purchase datasets of relevant B2B contacts from third-party data collection companies.
It compiles all of this data into a single source, cleaning and categorizing it via human input or machine learning algorithms—or a mix of both.
The data is then uploaded to the provider’s platform so you, the end user, can search it to find the best leads.
B2B data providers often create integrations with your other business-essential tools, like CRM (customer relationship management) software. This ensures that your sales and marketing teams can work seamlessly together to generate and reach leads.
How important is it to use a B2B contact database for leads?
So how important are B2B databases? And, do you really need a B2B data provider or can you go about things manually?
Every business has its unique needs and budget restraints. But, a good B2B contact database provider has a lot of benefits. Here are just a few:
Providers do all the work for you, collecting and sorting messy data from around the web and accessing third-party data that is often expensive.
Your sales and marketing teams have a single B2B company list to pull contact details from.
B2B data providers update and verify contact information for you, saving you time from bounced emails and dead phone lines.
The information in a B2B sales leads database is searchable, with customizable filters to drill down to the leads most likely to convert.
B2B data providers can find and highlight key decision-makers in a company.
Comprehensive lists allow you to learn more about your leads, letting you create hyper-personalized outreach that addresses them and their pain points.
You can focus your efforts on the leads most likely to convert and reach the right decision-makers with the right sales strategies.
B2B contact databases can generate more revenue for your business by automating the busy work and helping your sales and marketing teams focus on the most qualified leads.

How to choose the best B2B leads database provider for your business
When choosing your B2B contact database provider, it’s important to consider a few things. Let’s explore the most critical factors that will help you make a decision.
Database size and quality: If you’re paying for a service, you need to know it’s worth it. To assess a provider’s database, look at how many companies and individual contact profiles they list. It’s not just about quantity, though. Data quality is vital to streamlining your lead generation and outreach. For example, Dealfront has the largest B2B database in Europe, with over 40 million companies and 180 million contacts sourced from local registers in multiple languages.
Country coverage: Make sure the database provider you’re considering contains data from the areas you wish to market in. For example, few providers focus exclusively on European markets, making Dealfront a lead generation pioneer in the region, while other platforms like Ampliz Salesbuddy are ideal for those targeting Asian markets.
Update frequency: Databases with high levels of out-of-date or missing data will cost you time and money. Look for B2B data providers that regularly update and verify their databases. At Dealfront, we regularly verify all of our data to make sure you’re getting the most up-to-date contact details.
Features and filtering: Every B2B contact list uses a different platform. Some work like software; some load in your web browser; and some utilize browser extensions. Check in with the needs of your sales and marketing teams to understand which features and search filters you need to look for. Also keep in mind that some B2B data services have a steep learning curve, so if your team isn’t tech-savvy, look for a smooth user interface and low barrier to entry. Dealfront offers an all-in-one software solution as well as browser extensions for prospecting on the go.
Integration and ease of use: B2B data services need to integrate with your existing tech stack, either natively or by utilizing APIs to create custom integrations. Without these integrations, your sales and marketing teams will waste time and energy transferring information and workloads between different programs and databases. Dealfront offers integrations with the most commonly used sales and marketing platforms. If you don’t see an integration listed on our website, you can use Zapier to seamlessly create your one with your favorite tech tools.
Compliance and security: B2B databases contain personal data, including names and contact information, about business leads. This makes them subject to high levels of privacy and security scrutiny, however, data protection regulations can vary greatly between countries. This means that you have to be careful when choosing a platform to ensure your business remains compliant and avoids legal trouble. For the EU, the relevant data protection legislation is governed by the GDPR. Built in Europe, Dealfront understands and prioritizes true compliance and the highest data privacy standards. Instead of looking for GDPR loopholes, we focus on providing complete transparency for our data sources, which are chiefly official trade registers, with enrichment from public web data and directories. This means that you can confidently explain to your prospects which public source you got their contact details from instead of ruining your relationship with a prospect before it has even begun. We believe in true transparency, privacy, and compliance, and we are proud to help our users uphold these strong values as well.
Customer support: Paying B2B database providers means getting good customer service when things go wrong. You can’t always trust a company’s own words about the quality of their support, though, so read reviews and customer testimonials to find the truth. If you’re uncertain of anything involving Dealfront, we have a comprehensive help center with countless articles written by our experts as well as a dedicated customer support team contactable by email and telephone.
Cost: Costs vary greatly in this industry. Many providers state prices up-front, while others require you to contact them. Costs are often flexible, with different tiers and features available to suit unique budgets and needs. Look for price tiers that reflect your requirements, potential return on investment, and the quality and size of the database you’re gaining access to. Don’t be afraid to utilize free trials or freemium models to try before you buy. Book a demo with Dealfront to explore our features, and we’ll tailor a pricing model to suit your needs and budget.
