There's a difference between generating business value and generating profit. It's common for founders to get liquidity during financing events and this typically involves a sale of equity (i.e. transfer of business value from the founder to another stakeholder).

This is distinct than the company becoming profitable; many companies will increase in value while not being profitable.

The original commenter is making this comment I presume because he/she thinks Spotify is a mature enough business where it should be generating profits instead of operating at a deficit in order to grow and grab market share.

you're probably thinking of Pandora's CTO who has a gorgeous house there. Spotify's founders are from/live in Sweden.
