If it's just success stories, I don't think that you won't last long. To me, you also need to add something like the stories of start ups like what the site Trends does where they share stories of upcoming trends before they are even a thing. I like the idea but you might want to scale to more than just success stories because it will get stale or will eventually run out.

The only thing lacking is some sort of communication between each one of those creators and the readers, within your platform ^{[it'll also help with having a better retention rate]}.
^{- Just simply add a comment section and allow readers to ask other questions as well [you could also give unique badges to the creators so they're easily distinguishable from the rest].}

The interview looks fine, there's no obvious bias or stealth advertising. Although i don't have much interest towards DeFi, i'll bookmark your website for now. But do you plan to contact few famous people on DeFi? I doubt many people will bother contact you first.

Your plan project is so good since its good to read some stories came from different people but the question here is can you really convince people to share their success stories on defi's? Maybe not since people in crypto are into profits and this is also a risk to their identities since many people will know about little information about  them, so better compensate the writers a amount which you can afford to pay for the efforts they made to write a stories to your site. Maybe those compensations  could convince more writers since they can get paid for their amazing stories.
