It depends on what using Oracle means. As a backed? I seriously doubt it. Oracle fees are huge for startup-style growth and non-oracle equivalents are 1) cheap and 2) have plenty of talent available. If you're a start-up going after B2B market, and you want to offer on-prem service, I suggest you get into the Oracle developer network and try as hard as you can to make sure your product works with Oracle as a backend. Just having it as an option for big corporations is worth the effort... But not as a first time option (unless ORA funds you, which is another story).
