Not every moat in your portfolio is one.

AI isn't killing software.
It's removing the reason to buy it.

The companies that survive share four things. Every one is a reason the customer still has to buy.

The Durability Stack
01
Encoded domain knowledge.
The domain is structured into something a customer would have to rebuild from scratch and keep current as the rules move.
02
Regulatory standing.
Taking it back means owning the risk of getting it wrong. Few customers insource a liability they can offload.
03
First-party data.
The longer customers stay, the more the data compounds. Leaving means rebuilding it from zero.
04
Attention & distribution.EMERGING
Even when the capability is replicable, being the default channel isn't.
