Apart from tapping onto Sophia's popularity and recognition, I don't see that they have done much, if not any marketing on SophiaVerse. Currently on their Twitter the only tweets are explanations regarding the SophieVerse, such as what SAOS is, their Wallet and uses, an Introduction to SAIL, and how the Sentience Code works. It would've been more interesting if they are partnered/invested in AI/Metaverse focused platforms/firms, but I'm assuming they are unable to do so because of a lack of token specifics and details.
Assuming that they are targeting for launch very soon, they are severely lacking in marketing. The only notable update is being mentioned in Binance's AI x Crypto Report as a Case study for "Improving the Metaverse Experience).
