Leadbay
Qualify millions of data-signal-scarce leads
We built Leadbay to help sales teams find and qualify leads that have little or no data signals available anywhere else. Our product uncovers millions of leads that traditional tools can't find and qualifies them, giving customers a much larger and more accurate addressable market. For example, teams at L'Oréal and Nespresso have tripled their market and found 10x more qualified leads using our AI-driven platform.
We live and work in San Francisco, CA. After YC, the company will remain based in San Francisco.
San Francisco is where we live and have access to skilled AI and B2B talent. It's also where many of our customers are, making communication and growth easier post-YC.
