AI-qualified B2B leads, delivered into your agents
Upload historical outcomes and Leadbay extrapolates what your best customers look like, then hunts for lookalike accounts and contacts in under-served markets.

Every like, dislike and outreach action feeds back into the model, so recommendations sharpen as your team uses it.
Qualified leads arrive with people, phone numbers and email addresses attached, reducing the enrichment step before outreach.
