Any examples of failed/scam crypto businesses compensating customers in the end?

Apologies if this is a noob question or if it's been answered before. I'm new to the space and I'm still trying to understand the history of crypto so far. I keep seeing posts of people saying once you've lost the money it's gone. I know there's a difference between scams and failed businesses but I guess I'm wondering if there are any examples of people being fairly compensated either through law enforcement action or by the founders of these businesses in the past and how that worked out.

I know that in the Coffeezilla Cryptozoo scam it took a YouTube investigator to post a public investigation to get the promise of compensation for investors. Even then it's just a promise until it happens. In the American based businesses it seems that people get a fraction of their investments back after many years. I haven't come across solid businesses that genuinely failed due to external factors that may have actually tried to make their investors whole again so far. Are there any?

This is obviously discounting the Do Kwon type of scammers who ran off with the money specifically to evade accountability.
