I haven't been to a demo day in a while but it's typically been split into an "on the record" group and an "off the record" group. Startups like to share their MRR number because it can help grab the attention of potential investors.
Yup. But afaik most founders don't want this info to be public. (I'm an investor and was at demo day. I seem to recall that previous TC coverage described what each company did without exposing metrics, but I could be wrong.)
Right, I was at Demo Day today. They warned us repeatedly, that unless we opted in to the "off the record" group, anything we said was fair game to become public.
