Multi-Drive Storage Gateway

Users struggle to manage multiple Google Drive accounts and hit storage limits. 9Drive creates a single dashboard to connect multiple Drive accounts, automatically routing uploads to accounts with available space, and providing unified file organization and quota tracking.

Google Drive's 15GB free tier hasn't changed in years while file sizes have ballooned, and the pattern of people creating throwaway Gmail accounts just for storage is well-documented in forums and Reddit threads. No clear incumbent owns this exact space — MultCloud handles multi-cloud transfers but isn't focused on the quota-routing and unified-org angle. The $500–2k/mo revenue band is believable given this is a convenience tool people will pay a few dollars a month for, but the ceiling is real because most users hit this pain point once, solve it with a workaround, and move on rather than paying recurring fees. The biggest risk is Google quietly raising free storage limits or bundling a better multi-account experience into Workspace, instantly evaporating the core value proposition.
