What is Data Enrichment?
Data enrichment is the process of enhancing existing data records with additional information from external sources, improving accuracy, completeness, and usefulness for sales and marketing teams.
Data enrichment is the practice of taking an existing dataset - typically a CRM, marketing database, or lead list - and appending additional information from third-party sources. This might include adding missing email addresses, phone numbers, job titles, company revenue, industry codes, technographic data, or social media profiles to records that previously had only basic information.
For B2B organizations, data enrichment is essential because the data collected at the point of lead capture is rarely sufficient for effective outreach. A webform might collect a name and email, but sales teams need to know the prospect's title, company size, industry, and technology stack to personalize their approach and qualify the lead against the ideal customer profile.
There are several types of data enrichment. Contact enrichment adds personal and professional details to individual records. Company enrichment (also called firmographic enrichment) adds organizational data like revenue, headcount, industry, and location. Technographic enrichment reveals the software and tools a company uses. Intent enrichment identifies signals that suggest a company is actively researching a solution.
The enrichment process can be batch-based, where a list of records is processed at once, or real-time, where records are enriched as they enter the system. Real-time enrichment is particularly valuable for inbound lead flows where speed-to-response matters. Batch enrichment is better suited for periodic database cleanup and enhancement.
Cleanlist approaches data enrichment through a multi-provider waterfall model, which means each record is checked against multiple data sources rather than just one. This significantly increases the likelihood of finding accurate, up-to-date information. The platform normalizes data from different providers into a consistent format, resolving conflicts and deduplicating results to produce the cleanest possible output. Teams can enrich records via CSV upload, API integration, or direct CRM connection.

What types of data can be enriched?
Common enrichment data types include contact information (email, phone, job title), company firmographics (revenue, headcount, industry, location), technographics (software and tools used), social profiles (LinkedIn, Twitter), and intent signals. The specific fields available depend on the data providers used in the enrichment process.
How often should B2B data be enriched?
B2B data should be enriched at least quarterly, though monthly enrichment is ideal for high-velocity sales teams. Job changes, company growth, and technology adoption happen constantly - studies show that 30% of B2B data decays annually. Real-time enrichment at the point of lead capture is also recommended to ensure new records are complete from day one.
What is the difference between data enrichment and data cleansing?
Data enrichment adds new information to existing records (e.g., appending a phone number to a contact that only has an email). Data cleansing corrects or removes inaccurate, incomplete, or duplicate data that already exists. In practice, the two processes are complementary - Cleanlist combines both enrichment and cleansing to ensure records are both complete and accurate.

Firmographic Data
Firmographic data describes the characteristics of a business organization, including industry, revenue, employee count, location, and company structure - the B2B equivalent of demographic data.
Waterfall Enrichment
Waterfall enrichment is a data enrichment strategy that routes each record through a sequence of data providers, moving to the next source only when the previous one fails to return a match.
