Thanks for the question!

We plan on charging firms on a per case basis.

Eventually we also plan to to sell to other customers, particularly courts and prosecutors, but we have to start somewhere and this is where we felt there was the biggest mismatch between need and current tech.

Both prosecutors and courts have more money than PDs (generally), but they are also much much harder markets to crack since they tend to be more directly integrated with the governments IT and contracting infrastructure.
