This is the layer the core thesis overweights. The moat here survives model commoditization because the asset is the proprietary data loop, not the model on top of it.
Closed-loop genomic, clinical, and imaging data compounds with every patient encounter. It cannot be replicated by a fast follower or a frontier lab, and it strengthens the more it is used. The trade-off is capital intensity and slower ramps — but the retention and defensibility are the highest in the sector.
