I have experience with carta as an angel only, and I can say that in comparison to AngelList, Odin, Mara and Uniborn this is the worst experience I had from a platform.
Can't find the wiring instructions. ACH failing. Support that's only PST for a company that serves the whole world.
I've heard from funds, it can be an ok solution, but if you are a founder and you are doing a round, I'd recommend looking elsewhere for your investors.
