On the top of my head, I remember LTO and Sharering who managed to get a partnership with businesses outside of the crypto ecosystem such as the UN, and some small businesses that I can't remember. The use case is quite simple though, mostly just data stamping on the blockchain as a way to secure digital identity information, not that complicated and unique in this day and age. However, they have connections that allow them to reach out to markets that are not saturated with crypto jargon. Unfortunately, it doesn't reflect that well on their token price, since most people want to jump on the newest hype instead of a growing business. So I'm not sure if they'll even be around in the next 3 years or so.
