We are often asked for a number: how many weeks of events before a report is worth commissioning. The honest answer starts with the marketplace’s calendar, not with a rule of thumb from another practice.
Hari Raya, Chinese New Year, and school holidays move food and ride-hail volumes in Penang enough that a window sitting entirely inside those weeks will describe a festival, not the ordinary first week of a new account. Conversely, a window that avoids every holiday in a young app may be too small to see seller activation at all.
For a two-sided report we look for a stretch in which both new buyers and new sellers appear in numbers large enough to narrate — not to claim statistical theatre. If a B2B parts app on the industrial estate signs eight new suppliers in a month, the seller chapter will be a set of account stories, and the report will say so. Padding those eight with older accounts just to draw a funnel is a different job.
Bring what you have. In the kickoff we will say if the window is a festival, a drought, or usable. If it is unusable we will recommend waiting rather than charging for a document that only restates the problem of sparse events.
