It is difficult for me to answer. I know that you have a very good base.
As far as I understand, the infrastructure is in place. I think the ability to keep registries also already exists, as there is really nothing exceptional to that.
Do you need to hire more people? I cannot speak to that, but I would not be surprised if you did. However, I don't think that you need to make massive hirings, as you already have a solid team.
