After a long drought, the go-go days of hot technology IPOs appear to be back. The new age began last week with the long-awaited public offering of shares in ride-hailing service Lyft, which raised more than $2 billion for the company with a valuation climbing to over $26 billion before falling back to earth on Monday. To put that in perspective, Lyft’s valuation after the IPO rivaled those of Snapchat, Dropbox, and Spotify; it’s larger than all of this year’s IPOs combined.
