The email you are seeing from Carta is legitimate.
During our Title III (RegCF) campaign on StartEngine, we happily gained over 1300 investors. One obstacle was issuing and tracking stock certificates. This is where Carta comes in. Carta is a capitalization table management and valuation system. Carta allows us to issue shares quickly and efficiently. Then for shareholders, view their stake in Mycroft AI, track their investment (valuation changes), and communicate with the Mycroft AI team quickly (with regards to investments).
In regards to, “old certificates need to be destroyed,” we haven’t issued any paper certificates so there’s nothing needed to be destroyed. Our certificates are issued digitally while maintaining all the same legal protections and legitimacy as a physical stock certificate. This is legal wording that covers companies who have previously issued paper certificates.
I hope this helps clear up some questions.
