The only other premine was the IGNIS premine in 2018 which was 50% of the supply, from which the majority were sold in a second ICO (for ARDR or NXT, I don't remember well). IGNIS however crashed pretty fast in 2018, so while I guess they made some money with that, it also were not big amounts compared to other ICOs of that time.
Jelurida actually made a ton based on the Ignis ICO.
They admit to making over 15M from the ICO alone.
This doesn't count the NXT/ARDR/IGNIS pump ... a lot of the ICO was paid in NXT, which conveniently had like a 10x runup right after the ICO ended.
They made out like bandits.
