The top data enrichment companies right now

Data enrichment is useful for discovering new customer data, and expanding upon the data your business already has. A good data enrichment vendor allows you to enrich low quality records, thus improving the ability to tailor personalized offerings to the right customer at the right time. Here are the best data enrichment tools in 2021.

Data enrichment is a critical component of your customer data strategy. This article walks through a large list of options for data enrichment companies, what you can use them for, and some recommendations for the best partners depending on your specific sales or marketing need.

Maintaining high quality data in your customer data stack sometimes requires external inputs like data enrichment tools. So if you’re looking for a data enrichment partner, this list is a good place to start. The industry has come a long way since its humble beginnings when you’d file-transfer a .csv to a provider who’d spruce it up and send it back.

What is data enrichment?

“Data enrichment” refers to software that takes a person’s email, LinkedIn profile, phone number, or company website, and checks its own database for a match. If it discovers a match, it sends back data to fill other fields that may be missing. The data enrichment provider’s database then “enriches” these missing fields. You can also think of data enrichment as the process of enhancing, changing or improving existing datasets by adding additional information or attributes to them. 

You essentially supplement raw data with more detailed, relevant or valuable data from external sources. To clarify, raw data refers to original, unprocessed and untransformed data that’s collected directly from its source. It’s the most basic form of data (often in its native format) without any modifications, calculations or organization applied to it. 

The general purpose of data enrichment is to enhance data quality so it’s more useful for analyzing other business purposes.

Here are some techniques used to enrich data:

  • Sourcing demographic information: Adding demographic data (such as age, gender, income, or education level) to customer records or contact lists will give you a better understanding of your target audience. You can also use this demographic data for marketing or segmentation purposes.
  • Geolocation data: Using geographic information (such as latitude and longitude coordinates or ZIP codes) to enrich your data will help with your location-specific insights. This can be useful for geo-targeting, localizing services and analyzing regional patterns.
  • Social media data: Gathering and integrating social media profiles, posts and interactions with existing customer data. This helps you understand customer preferences, sentiment analysis and also how to identify influencers.
  • Firmographic data: Adding business-related information (such as industry type, company size, or revenue) to enrich datasets for B2B analysis or sales prospecting.
  • Third-party data: Integrating external data sources (such as market research reports, public records or government databases) to expand the scope and depth of existing data records. It also provides a broader context in terms of industry benchmarks and market trends.
  • Data normalization: Data normalization is a technique used to transform data into a consistent format, making it easier to analyze and compare. It’s often considered a part of data preprocessing, which is an essential step in data enrichment. 

Standardizing and regularly cleaning your data ensures its consistency and accuracy across different sources (and formats, too). This involves processes like deduplication, name convention standardization and resolving any outstanding inconsistencies. 

The overall objective of data enrichment is to improve the quality and completeness of data. This enables organizations to gain more comprehensive insights, make better-informed decisions, and create personalized experiences for their customers.

As you consider the various types of data enrichment and the unique needs of your business, you may want to ask yourself: what type of enrichment do I need?

Types of data enrichment 

Data enrichment — the process of appending additional data to a list, or updating select values to make the data more “fit”— comes in several sizes. There are one-off enrichments, like the sort of cleanse you might conduct upon inheriting an old CRM instance, or double-checking a target account list. And then there are ongoing enrichments where bots make many minor changes as updates arrive, like correcting a contact’s title after they’re promoted.

Then there are enrichments for different roles — for operations, for marketing, and for sales. Operations and marketing enrichments tend to happen on a grand scale. They may require significant work to upload and operationalize. Whereas sales enrichments may be one-offs — like pulling a new target account list, or tiny changes here and there such as verifying a single email at a time.

Which one you need all depends on what you’re running into.

Which types of data enrichment do you need?

Which types of data vendors you need depends on your objective. For most sales organizations, however, the first step is account identification – in other words, which companies to target. Some data enrichment tools do both company and contact lookups (ZoomInfo, Cognism, Apollo.io), but there are specialist tools like BlueprintGTM.com or Keyplay.io that do account identification.

The second step then is identifying which people to reach out to at those accounts – contact information lookups. Tools like RocketReach, Uplead, or Clearbit are often chosen for this step.

There is a third layer of enrichment that is often overlooked, which is human validation on the contact information you receive from a data enrichment tool. There are not many vendors in this space, but Phone Ready Leads and Cloudlead are good examples.

Benefits of data enrichment

Big one-off enrichments are great for a refresh, but they don’t combat some of the most pernicious issues that affect data quality, such as plain old time (people move jobs, swap out marketing softwares, etc.) and APIs. 

Few companies realize what a mess many interrelated systems linked with pre-built connectors can make. Without any central intelligence or sense of which system or person has the authority to update a field, changes can create a lot of mayhem. MIT estimates bad data of this sort is responsible for chipping away at 15-20% of the average company’s revenue

One of the best things you can do, then, is enrich continuously—and implement continuous fixes. The more often the system is updated, the more opportunity it has to catch issues before they compound. 

(If having a passive data defense sounds interesting, you may want to skip to Syncari.)

One thing to keep in mind as you evaluate multiple data enrichment companies, is where in your tech stack they send data. For instance, let’s say your marketing automation is HubSpot and you have Salesforce and Outreach, some marketing operations and RevOps leads prefer to have the data enriched in Salesforce there, and some in HubSpot. A lot depends on whether you have all your active contacts in both HubSpot and Salesforce (in this example).

Best for sales automation with embedded enrichment

Apollo combines the functionality of a sales automation and email sequencing tool, like Outreach or Salesloft, with a database of contacts and companies.

The list wouldn’t be complete without it. In all seriousness, sometimes you need data enrichment and sometimes you don’t. All too often, sales and marketing operations teams fix gaps in their data with the addition of new data. Sometimes this works, but often it’s a band-aid over the real problem (which is usually that existing data is getting lost or messed up). These data quality issues can be extremely painful.

The best fixes are automatic and continuous, and the more structure and governance you have in place, the less need you have for enrichment. And having automatic controls will only help you make better use of the data you do purchase. For example, if you have controls set such that the CRM has data authority over phone numbers, the correct numbers are safe from marketing enrichments.
