I came across this article :https://www.financemagnates.com/cryptocurrency/news/dappradar-secures-2-3-million-in-naspers-led-seed-round/?utm_source=dlvr.it&utm_medium=facebook
It reads "DappRadar Secures $2.3 Million in Naspers-Led Seed Round"

It seems as if this site that I didnt think of much before has allured investors like Naspers Ventures, Blockchain.com, Angel Invest Berlin etc to collectively invest in it. But what I cannot understand is, why?
How would DappRadar recoup the investors let alone make a ROI? I don't know of any sustainable revenue model from DappRadar, are they now going to charge listing fees from Dapps to get listed there? But if they did that, wouldn't that go against the basic need of such a website that lists Dapps without any biases?

I am confused. Can someone explain this to me?
