What are the famous product (Successful) ever launched on PH

I was trying to look at the products launched on PH which became successful after being launched on PH but getting more up-votes/featured won't make any startup successful (Please correct me if i am wrong). Sometimes i really get to know about new unique products that can really help the masses with their solutions but not sure whether their valuations reach millions/billion dollar or they no longer exist. Do you know any really successful products?
