Entity Resolution

Also known as: record matching, deduplication, identity resolution

Entity resolution is the process of determining whether multiple records refer to the same real-world entity — the same company, the same person, the same domain. It combines fuzzy matching, domain anchoring, and confidence scoring to merge duplicates and prevent the same lead from appearing multiple times in a CRM or campaign.

Data Enrichment

Data enrichment is the process of appending missing or updated attributes to existing records — company, contact, firmographic, and technographic fields. It turns a thin list of names or domains into complete, actionable profiles. Quality enrichment is source-attributed and confidence-scored so each field can be trusted and audited.

Contact Validation

Contact validation checks that a contact record is accurate and current — correct name-to-email mapping, working email, valid phone, and a real role at the company. It removes junk, duplicates, and stale entries before data reaches a CRM, keeping pipelines clean and rep trust high.

Firmographics

Firmographics are the descriptive attributes of a company — industry, employee count, revenue, location, and ownership — the B2B equivalent of demographics. They are the primary filters for building a target account list and segmenting outreach, and a core output of company enrichment.

Sales Intelligence

Sales intelligence is the practice of collecting, enriching, and analyzing data about companies and buyers to inform outbound and account-based selling. It combines firmographics, contact data, and buying signals so reps know who to contact, why, and when. Unlike a static database, modern sales intelligence is continuously refreshed and source-attributed.
