Literally everything is a UI atop a database. Writing the data models, crafting the right uI and the right flows is non trivial. It requires iteration and that refinement is what customers pay for. The reality with SaaS stocks is they dont make anything critical. eg Take any large consumer tech company and they dont use Klaviyo. These companies build their own stack and one thats intimately connected with the data lake. It works for tech companies since they hve good data and it doesng work for non-tech companies because a good fraction of their data is trash.
