Selling to specific industries
Guides to finding and selling to businesses in one industry: how many there are, who decides, what they buy and where to find them.
Short answer
Each industry guide explains how to build and use a prospect list for one kind of business: how many establishments there are (from US Census Bureau data), how the industry buys, who the decision makers are, public sources for finding them, and an outreach angle that fits.
