Why Idea Filters Matter More for AI SaaS

In AI, capability is the cheapest part. Filters catch the trap of building because you can.

The AI-Specific Trap

• Model gets better. New thing becomes possible.
• You build it because you can.
• You ship to no one in particular.
• The next model release makes the demo a commodity.

What Filters Catch

• Reachability: do you know paying buyers?
• Adjacent spend: are they paying for tools nearby?
• Crowding: how many startups got the same model release ideas?
• Defensibility: is your wedge anything beyond the model?

Why It Bites Harder Here

Capability commoditizes fast. The filter is what keeps you from chasing capabilities that will not matter in three months.
