The number every EdTech team reports after a conference is scans. It is the easiest number to say and the least useful, because a badge scan only means a person stood close enough to the scanner. The pipeline lives in what you knew about that person while you were still standing in front of them, and if you wait until you are back at your desk to sort it out, you have already lost the signal. We have helped enough edtech companies clean up post-event pipeline to know this is exactly where most of it leaks.
The fix is a scoring model designed to run on the floor, in the moment, before the memory fades. It is worth adopting wholesale.
