Company Description

We unlock untapped revenue for sales teams targeting fragmented, data-scarce SMB markets — like construction, hospitality, startups, and retail. You might think that LinkedIn Sales Nav, Clay, ZoomInfo, or Apollo have you covered. They don’t. They miss 70% of U.S. companies and capture only 0.001% of digital signals or intent. We’re already working with enterprise clients who 5× their prospecting efficiency by simply unlocking hidden opportunities in the most data-scarce, fragmented markets. How does it look like? Upload a list of won/lost leads. That’s it. Leadbay understands your Ideal Customer Profile, discovers untapped opportunities in your market, and scores your existing dormant accounts. Every day, you’ll receive fresh, high-value prospects right in your mobile or desktop app. We make invisible companies visible.
