Here's a fun stat: a few years ago, I surveyed some of my fund's portfolio companies and asked, "for a similar level of product/service, how much higher or lower are your prices compared to your initial pricing?"

Out of a dozen replies, about 10% were pricing their product lower, 30% were pricing the same but taking higher margins, and 60% companies were charging 2.5x-6x more than they used to. Median was around 3.5x. So the majority of companies had marked up their prices severalfold, and only one company had lowered their prices.
