Last week, the initial public offering floodgates swung wide open, and it’s no accident that five of the companies that filed paperwork to sell shares to the public are software as a service businesses. 

The five companies—Snowflake, Asana, Palantir, JFrog and Sumo Logic—are in a sector that has proved to be one of the more resilient parts of the tech industry during the Covid-19 downturn. All of the companies have continued to show strong revenue growth since the pandemic began. Their filings are also packed with tantalizing tidbits about a variety of subjects, including their spending with big cloud computing providers like Amazon Web Services and the risk of political interference in the bidding for U.S. government contracts.
