eh. I built a lead gen system at a fortune 1000. The heuristic SQL version brought in 10M a year. The random forest version brings in 100M a year. It saw things we didn't
Set up a bunch of rules created by the sales team. Tweaked it over months. Made money
Then used real sales data tied back to search history and built a machine learning model. It found new patterns that the sales team hadn't thought of, and performs much better
