• SurveyMonkey's parent company, SVMK Inc., has confidentially filed to go public.
  • SurveyMonkey was last valued at $2 billion in 2014, though we don't have any indication that it will go public at that valuation.
  • It would be the latest enterprise software company to go public in a wild year for initial public offerings.

SurveyMonkey, a dot-com-era survey-software company, has made a big move toward going public.

SVMK Inc., the survey site's corporate parent, confidentially filed a draft S-1 with the Securities and Exchange Commission, it announced on Monday.

It isn't clear how many shares would be offered and at what price, though the company said its initial public offering "is expected to commence" once the SEC reviews its documents.

SurveyMonkey, founded in 1999, was last valued at $2 billion in a 2014 private-equity growth round, according to PitchBook.

It's been a busy year for enterprise tech companies looking to enter the public markets. Dropbox went public at an $11 billion valuation at the end of March and is now worth about $17 billion.

The software companies ZscalerZuora, and Smartsheet all went public in the first half of the year.
