What Leadbay is
Leadbay is an AI tool for B2B prospecting and lead qualification, backed by Y Combinator. You upload data on deals you won and lost, and it studies that history alongside company information and business indicators to predict which prospects are most likely to convert. The goal is to help sales teams spend time on high-intent buyers instead of cold lists. It also surfaces decision-maker contact information so outreach can go straight to the right person. It is used by sales teams in regions such as France and the United States.
What you can do with it
- Upload won and lost deal data for the AI to learn your pattern
- Get a ranked view of high-intent potential customers
- Read company context and business indicators for each prospect
- Reach decision-makers directly with the contact details provided

- Marketing staff who want to read buyer and market intent
- Managers who track sales performance and competitive position
What to watch out for
A free trial is offered, but exact pricing is not listed and may change, so confirm terms before committing. The quality of predictions depends heavily on the volume and accuracy of the deal data you upload, so thin or messy records will weaken results. It is designed for B2B prospecting, so it is not a fit for consumer-style lead gen. Treat its rankings as a guide to prioritize outreach, not a guarantee of a closed deal. Features and interface details may change between versions, so review the latest notes on the page before you start.
