“Can Wise extend its multi-currency account into a full financial OS by embedding investment products alongside FX and money transfer?”

The feature allows Wise account holders to invest directly within their multi-currency account, extending Wise's offering from pure FX/money transfer into embedded investment products. The known_customer_listings evidence (IBS Intelligence article) confirms this is a Wise product launch, not an independent entity.
