Fit before volume
Define the audience using explicit inclusion and exclusion rules before discussing how large the dataset should be.
Source B2B Data is built around a simple operating idea: prospect data is more useful when the audience definition comes before the file size.

A name and email can identify a person, but they do not explain why that person belongs in a campaign. Role, seniority, company size, industry, geography, technology use, healthcare specialty and organization context help teams understand fit.
That is why our service structure covers business contact and company data, healthcare audiences, technographics, appending, enrichment, account-based marketing data, custom research and licensing.
Projects can begin with an ideal customer profile, an existing account list, a CRM file that needs more fields, a healthcare specialty, a technology platform or a niche research brief.
These principles guide how the site frames every data service.
Define the audience using explicit inclusion and exclusion rules before discussing how large the dataset should be.
Choose fields based on how the team will segment, route, research, contact or enrich the records after delivery.
Data should be used responsibly, with the buyer responsible for applicable privacy, communication and marketing requirements in each market.
Send the target criteria, required fields and use case. We’ll start from the audience definition.
