AI made execution free. Knowing first is the whole game now.
The advantage goes to whoever is first into the right conversations, most often. Fundz stacks those odds: more of the moments that create demand than anyone else catches, as they happen, matched to who you sell to, with the decision maker to call. Now it answers in Claude too: ask for today’s leads and who to reach, then write the note in the same window. Not a feed. Not a list you rent. A system for being first.
