The main set is the broad one: roughly 270 million people with names, current and past roles, company, location and, where available, business email, personal email, mobile and direct dial. It also carries household attributes for consumer searches such as age range, income, net worth, homeowner status, marital status and children.
The deeper business profiles cover about 115 million people, with headline, skills, work experience and education, and work emails checked before you send. They are included on Growth and Scale.
Behind both sits a company layer of roughly 9.7 million company fingerprints, built from the people who work there, so Buzzlist can tell what a company actually does even when its industry code is wrong.
Counts are refreshed with each data release and rounded here. What matters more than the total is whether the people you sell to are in it, which you can check on the free plan before paying anything.
