Kero research

Before anything is designed, find out what exists, why it fails, and what one sentence explains it. The output is a diagnosis with sources and a thesis.

Facts

  • Every claim carries its source. A link, a store listing, a public filing, a page anyone can open. If it cannot be checked in a minute in front of whoever decides, it is an opinion and is labeled as one.
  • Measure what exists before imagining what could. What the client uses today, what it costs, who uses it and how much. "There is no app" is a finding; "the app is bad" is a guess until it is shown.
  • Numbers come with their source and their date. Downloads, ratings, prices, sizes and revenue age fast. A number without a date cannot be compared with the next one.
  • Assumptions are written next to the figures they shape, never folded into them.

The competition

  • Read what their users say, not the score. Ratings say how many are unhappy; reviews say why. The repeated complaint is the product gap.
  • Look at what the best competitor already proved for free. What works at their scale is a pattern; what their users keep asking for is the opening.
  • Separate who pays from who uses. Many products fail because the person who benefits is not the one who buys.
