WHO WINS THE AI APP LAYER?

Summary from the TLDR Founders newsletter

AI labs are now shipping products aimed right at vertical AI customers, like OpenAI's tool for lawyers that launched a week after Harvey raised at $15.5B. Most of the value still lands with the apps, as long as they own data the labs can't simulate or buy. Coding took off because the labs can grade it automatically, so the moat is outcome data that only exists when someone does the job, like whether a loan defaulted or a claim got approved. A quick test is to list every outcome your product touches and capture the job byproducts as structured data from day one.
