What I Would Fix First About Idea Filters (AI SaaS)

Three changes that lift filtering for AI founders fast.

Fix 1: Add a Defensibility Filter

F5: "Is the wedge anything beyond a model call?" If no, kill or refine.

Fix 2: Add a Token Economics Test

Run unit-economics math at 100 customers. If gross margin is below 50%, the idea is borrowed.

Fix 3: Reachability Before Capability

Can you reach the buyer? If no, capability does not matter.

What Stays the Same

Four core filters. Same questions. The AI version adds two, not replaces.
