What was AscendEX formerly known as?

Could you please clarify for me, what was the previous name of AscendEX? I'm trying to understand the history and evolution of this cryptocurrency exchange platform, and I'm curious to know what it was called before it became AscendEX. Is there any significance behind the name change, or was it simply a matter of branding and rebranding? I'd appreciate any insights you can provide on this matter.
