Fastly, a startup that helps websites run faster, is set to go public this week on the New York Stock Exchange under the symbol "FSLY." If Fastly prices at the high end of its $14 to $16 range, the IPO could value the company at $1.45 billion. It's much lower than Uber's $75.5 billion market cap at the time of its IPO, but don't let that fool you — Fastly has more in common with this year's crop of successful enterprise tech IPOs, like PagerDuty and Zoom, than it does with any car-ride company.
