Legal AI innovation is scaling parallel queries, not prompt engineering
“And the big innovation there does not really come from, you know, how do you prompt and work with the model, but it's how do you make this run at scale? You know, how do you run a 100,000 queries in parallel at the same time and make sure nothing breaks.”

Junestrand: Legal AI will not cause a pricing race to the bottom

Bottom-up PLG is impossible in legal software due to strict procurement

Legal AI requires custom domain-specific prompting beyond raw LLM output
