About Leadbay
Summary
Leadbay qualifies B2B leads in markets where data and signals are scarce, including construction, hospitality, manufacturing, and healthcare. Sales teams use it to prospect accounts that conventional filter-based or signal-based tools cannot surface, replacing the manual research and judgment a top sales rep would otherwise apply. The platform learns from a team's won and lost deals, then feeds qualified, ranked accounts directly into AI agents running on Claude, ChatGPT, or Copilot.
Business model
A free tier plus a paid plan, with a tailored demo entry point for larger teams.
Go-to-market
SMB-to-enterprise sales teams sign up via a self-serve free tier or request a tailored demo; the product is ready to use immediately on login, seeded from the customer's own website and deal history.
