“We have been tracking the development of ShareIn's technology for many years and have been impressed by what they have built. Our new council lending proposition is building momentum, it therefore felt like the right time to migrate and set ourselves up for the next phase of growth. We have been very impressed with how ShareIn managed the migration, it was painless!”
