    With all of the tools out there today for B2B sales and marketing, which B2B data provider is the best for your company’s success? 

    Clearbit has touted its B2B intelligence and “real-time” verified data updates, while 6sense advertises AI-generated data for sales and business growth. 

    Which of these platforms offers accurate, verified B2B data that is right for your business? Here’s our in-depth comparison to help you identify which tool is best for you and your sales team.

    Clearbit Overview

    Clearbit

    Clearbit is a well-known data analytics tool that provides a variety of integrations and built-in tools to help businesses enrich their customer data, identify key industry contacts, automate tasks, improve their security, provide real-time insights, and predict customer behavior. 

    Clearbit collects reliable information from the web and its proprietary data and converts this information into detailed, standardized data sets. They have also recently partnered with HubSpot to further help businesses through “Breeze Intelligence,” which gives users all of the data needed to boost their productivity and scale growth. The overall goal of Clearbit is to ensure that customers have the right data to make more informed decisions, target key contacts, and improve sales results.

    6sense Overview

    6sense

    While 6sense may not have a partnership with HubSpot, they do claim to be the only ABM platform powered by Revenue AI. What does this mean for the company and how does it make them stand out? 

    6sense can help a business’ sales team drive growth and revenue by streamlining account-based marketing practices with AI. The tool helps identify key accounts, craft tailored messages, and assist with cold outreach, all in one platform.

    This is done by using data to understand the behaviors of these target contacts and then engaging them with the right message at the right time.

    Key Features of Clearbit vs. 6sense

    Here’s an overview of what we feel are the top five features of each platform to help you see how they stack up.

    Clearbit Features

    Clearbit provides a variety of APIs and data-rich tools for small to large-size businesses. Unlike 6sense, which focuses more on sales and marketing tools, Clearbit creates more detailed and accurate customer profiles for users: 

    • Data enrichment: Users can enrich their customer data through Clearbit’s process of including additional customer information and details to their existing data records. This means you can get your customers’ accurate email addresses, social media profiles, and the job titles and industries of important leads.
    • Personalized marketing messages: Once you attain customer and lead information, Clearbit will help you personalize your marketing messages by using Clearbit’s detailed customer profiles. That way, you can create marketing messages that are actually relevant to potential clients.
    • Automated data entry: Similar to 6sense, Clearbit also improves the efficiency of your sales and marketing teams by automating data entry and other routine tasks so that your team can focus on more important responsibilities.
    • Enhanced security: Clearbit’s Risk API will enhance the security of your business’s data to identify and prevent fraudulent activity.
    • Provide real-time data insights: One of the most important features that sets Clearbit apart from 6sense is its real-time insights and recommendations for your sales and marketing team. Clearbit’s Enrichment API automatically adds missing information to your customer data records to help your teams gain a better understanding of your customers’ immediate needs.

    6sense Features

    Here are 6sense’s top features you should be aware of: 

    • Predictive analytics and intent data: Predictive analytics help users time their campaigns based on where their potential buyers’ specific interests are, while intent data helps users focus on prospects with the most muscular intent.
    • Personalized emails: 6sense also crafts conversational emails that can be personalized for leads, saving time for the marketing and sales team while driving up engagement.
    • Real-time data: Similar to Clearbit, 6sense also provides access to real-time contact and company data.
    • Multi-channel outreach and custom segmentation: From email to advertising, 6sense automates cross-channel outreach and detailed audience segments for better marketing campaign performance.
    • Chrome Extensions: Account insights are delivered directly within B2B websites, such as LinkedIn, through a handy Chrome Extension.

    Winner: Clearbit

    While it’s close between the two, we’d choose Clearbit as the winner in overall features. With a well-rounded host of features and an easy-to-use platform, Clearbit is a better choice to enhance lead gen activity in your business.

    Clearbit vs. 6sense Database

    Database size and accuracy are crucial for any B2B lead generation database – here’s how these two compare.

    Clearbit Data

    Clearbit’s database consists of 395 million contacts spanning 20 million companies in 165 countries. The platform utilizes 250 different public and private data sources and sorts through billions of data points to add to its database. 

    This information includes social media profiles, company websites, and legal findings, among other important pieces of information. Every record goes through four stages of verification – ensuring the record has been refreshed within the last 30 days, seeing if the data sources agree with one another, looking for any anomalies, and sending the data through a team of researchers.

    6sense Data

    The 6sense database has more than 400 million B2B buyer profiles, 65 million company profiles from across more than 200 countries, 60 million direct-dial phone numbers, and 100 million verified email addresses. 

    Accuracy is key here, as all of this data is stored on buyer profiles that first pass through numerous validation levels so that the contact information continuously goes through a vetting process. Companies can use their B2B account and contact data search engines to engage with prospects that meet their specific needs. 

    Winner: 6sense

    Both tools offer good verification practices, so the winner comes down to database size – with a slightly larger database, 6sense takes the win here.

    Plans & Pricing

    Here’s what you need to know about plans and pricing for each platform.

    Clearbit Cost

    Clearbit is much more transparent about pricing than 6sense, so here’s what you can expect across their plans:

    Free Plan

    • 25 monthly credits
    • Best for individuals or small teams exploring data enrichment

    Growth Plan ($150–$275/month)

    • 125 to 1,000 monthly credits
    • Lead discovery and visitor identification
    • Designed for growing businesses

    Business Plan (Custom pricing)

    • Volume-based pricing tailored to business needs
    • Comprehensive company and contact enrichment
    • Lead scoring and form optimization
    • Best for larger enterprises

    Enrichment Batch Service ($0.10 per accessed record)

    • Provides instant context on leads, contacts, and accounts

    6sense Cost

    6sense has no published pricing, meaning you’ll need to contact the sales team to get a custom price quote. Additionally, there is no free trial available, meaning customers can’t really get a sense of the product before committing to a purchase. In reading customer reviews, pricing may be high compared to competitors.

    Winner: Clearbit

    Without transparent pricing, it can be difficult for businesses to understand if the platform is even an option – not everyone wants to connect with a sales team to get an initial understanding of the cost. 

    Integrations & API

    Both Clearbit and 6sense offer a wide range of integration options, so here’s how the two compare in integrations and API capabilities.

    Integrating With Clearbit

    Clearbit clearly leans into its CRM integrations with HubSpot and Salesforce as a means to enrich users CRM data. Clearbit also allows users to build targeted lead lists and personalized marketing efforts through marketing automation tools like Pardot and Marketo. 

    This way, users can integrate their advertising platforms with their social media platforms to build target audiences and through advertising sites like Google Ads to personalize their advertising campaigns. Finally, sales teams can integrate with sales engagement tools like SalesLoft and Outreach.

    Integrating With 6sense

    6sense has impressive CRM integrations through seamless data synchronization using built-in integration platforms like Microsoft Dynamics and Salesforce. This integration platform allows users to effortlessly leverage the company’s predictive analytics and account identification competencies directly within their CRM. 

    Similar to Clearbit, 6sense also integrates with many popular marketing tools like HubSpot, Marketo, and Pardot so users can coordinate a multi-channel messaging campaign to target specific accounts. 6sense also integrates with popular social media platforms so that users can target high-priority accounts with personalized ads on LinkedIn, Facebook, and Google Ads.

    Winner: 6sense

    6sense offers better data synchronization, while Clearbit’s integrations require more manual setup and data syncing. Remember that Clearbit primarily integrates with HubSpot, while 6sense integrates with other popular sales and marketing tools like SalesLoft, Outreach, and CRM systems.

    Clearbit vs. 6sense Implementation

    Usability is key to any business intelligence tool, and both Clearbit and 6sense tout their ease of user experience and implementation. Let’s see if they are as easy to use as they claim.

    Clearbit Usability

    Unlike other ABM platforms that sometimes take weeks or months to implement, Clearbit can be up and running in a few minutes. Then, it is easy to use with one-click native integrations with CRM systems like Salesforce and marketing automation platforms like HubSpot. 

    6sense Usability

    Users have noted that if they do not have experience with advanced ABM platforms, they have more trouble implementing 6sense. Expect a learning curve when the platform is up and running.

    The platform itself was designed to be user-friendly, yet navigating through the setup process and then leveraging the interface could take some time to get used to in everyday settings.

    Winner: Clearbit

    Clearbit’s quick setup and ease of use make it the clear winner in this category.

    However, as we mentioned, implementation time can be long, and there is a learning curve to the platform. The tool may be better for larger, more established sales and marketing teams.
