If https://site.warrington.ufl.edu/ritter/files/IPOs-VC-backed.... is right, the last time there were 150+ tech IPOs in a year was 2000 (1992-2000 were all anomalously high). 2021 is the only year to break 100 since then, and only three other years cracked 50.
Spotify: up 380% since IPO
Service Now: 4,000%
