In founders' words

The next Salesforce will be a suite of Sales & Marketing blocks used directly in Claude, ChatGPT, or Copilot. These blocks are innovative in four ways:

1 - A new way to qualify data. Ludovic Granger Beyond filters and signal-based tools, Leadbay searches, reasons, extrapolates, and qualifies the most data-scarce markets - the way your best reps would.

2 - It works the moment you log in. Milan Stankovic Your leads are already qualified, built from your website and your past won/lost deals. You like. You dislike. You contact. Every action pushes you toward better prospects.

3 - Agents that improve themselves. Ludovic Granger Leadbay learns what your best wins look like, then uses every frustration you share in chat to get sharper over time.

4 - Its own UX/UI library, native to MCP. Milan Stankovic The Leadbay MCP ships a full library of UX/UI components, so you can build apps shaped to your company's context and workflows. As it should be.

In investors' words

Garry Tan
AI can dig deeper and discover leads that just don't exist in existing data platforms — because you can “just think harder” and do more work than ever before. The result is new useful Glengarry leads which everyone wants.
