Leadbay

Discover and qualify SMB leads others can’t find.

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.

ORIGIN STORY:

Milan (CTO) is a knowledge graph pioneer who’s been perfecting LLMs in information-poor contexts for 15 years.

In 2023, he joined Ludo (CEO), who had brought a community of 300 sales reps from his family and VC background — the perfect playground to iterate on underserved use cases.

Together, they set out to tackle what every sales team wants: discover and qualify untapped opportunities.
