All your meetings have gone well. Everyone you talked to at your buyer's organization was really engaged. You asked good questions, and they gave great feedback. They really seemed to grasp how your particular solution could help their business.

But even if your tech team had moved faster, you wouldn't have won the deal. In fact, you were never going to win the deal for one simple reason: You didn't have an an internal advocate to carry the deal across the goal line.
