My preference is to remain on Crowdcube. I like the platform and user friendly. The main reason for me is consistency - all shares held on the same platform makes it far far easier, plus as an existing investor I think a Crowdcube has a greater profile and reach, and therefore is more likely to facilitate a successful raise (in terms of total capital) vs Seedrs.
I don’t think there is a huge difference, the difference in fee is negligible. Comes down to how comfortable you guys are on the back end, frankly it is more simple to stick with CC unless there is a particular benefit to switching.
Due diligence is not a consideration - Freetrde do not filter good/bad companies on their platform, if a PLC goes bust I’m hardly blaming the broker.
