The difference is that it almost never makes sense for a company to use cryptocurrency technology "internally". If you don't want to be a Bitcoin-esque distributed anonymous organization -- if you want to be able to comply with laws or sign legally-binding contracts, for example -- traditional database technology is much cheaper and easier to use.

Some companies have announced cryptocurrency-related initiatives, but the only benefit to them is that lottery-like speculator behavior might pump up their stock. (See companies like Long Blockchain, formerly known as Long Island Iced Tea.)
