Why I built Leddy.
I started building AI automations at 15. The more outreach I ran for those projects, the clearer it got: the part I loved wasn't the tools. It was the buyer. What makes a stranger stop, care and reply.
That became an obsession with buyer psychology and the math of growth. A business is a formula: people reached, replies, calls, deals. To scale it, you find the number that's holding you back and fix that one first.
Leddy is that obsession, run for B2B companies. Our data pipeline finds who's ready to buy. Earned Outreach earns their attention before it asks for anything.
