Why Three Groups? (and Not Four, or Two)
The grouping wasn't arbitrary. It was based on the mental model of OurCrowd's users, the way they actually think about the platform and what they come to do on it.
Investors naturally move between three modes: discovering what's available, managing what they already own, and handling account-level tasks. Explore, My Investments, and General map directly onto those three modes, which means users don't need to learn a new system. They already understand it intuitively before they've even clicked anything.
