ironically, there are no underwriters in the Spotify IPOThe governments don't rule the world, Goldman Sachs rule the world
-Alessio Rastani
"There are no underwriters. Consequently, prior to the opening of trading on the NYSE, there will be no book building process and no price at which underwriters initially sold shares to the public to help inform efficient price discovery with respect to the opening trades on the NYSE. Therefore, buy and sell orders submitted prior to and at the opening of trading of our ordinary shares on the NYSE will not have the benefit of being informed by a published price range or a price at which the underwriters initially sold shares to the public. "
So, apparently they are fine doing this without a investment bank 'stamp of approval'
