Productivity problems worth solving.

Productivity has been the most-shipped software category of the last decade, yet the people inside it still lose hours every week to coordination overhead, context switching, and tools that don't quite fit how they actually work. The problems collected here come from the operators on the receiving end — managers, makers, founders — not from product marketers.

Every problem on this page carries a 1-100 opportunity score that blends pain, frequency, market reach, and dollar loss. The highest-scoring entries are the kinds of frustrations that have lasted long enough to be obvious and stayed unsolved long enough to be earnable.
