Stack Assets

[PlanesTrainsAutomobiles]

Do any of you know what happened to Stack Assets? They were a fractional asset ownership platform. Some years ago, I invested a small amount of money with them. In anticipation of investing in an asset, they created Investec accounts for each owner. I used to receive statements directly from Investec. This stopped, and when I checked after a while, I saw that the app was no longer functioning.

Any way in which to retrieve the investment?
