What a difference a few quarters make! In the past nine months, Series A valuations have skyrocketed. In fact, 2014 Series A pre-money valuations have surpassed Series B valuations from 10 years ago, accounting for inflation. The same is true for Series B valuations exceeding median Series C valuations a decade before.
Or as Ben Narasin wrote back a few months ago, the Series A is the new Series B.
