Why market research matters to a first-time founder
Every early decision about price, channel and features rests on assumptions about customers and competitors. Research tests those assumptions before you commit money or months to them. Skip it and you risk building for a problem buyers do not rank highly, pricing above what they already pay for alternatives, or entering a market a competitor already serves well. Good research is cheap compared with a failed launch, and it should be able to change your mind.
Examples of market research
A founder talks to fifteen freelance designers, asks what they do when an invoice is thirty days late, and notes the price of two tools those designers already pay for. That market research can overturn a guess. A poll of friends cannot.
Common misunderstanding
A stack of articles, or a survey of people who already like you, is not yet market research. Research can be traced back to customers, competitors, or the market, and you have to be willing to drop an idea because of it.
When to use it
Do it before you lock a price, a sales channel, or a feature that would be expensive to undo. If you already have paying customers, start with what they do. Their behaviour is the market research.
