What these fields mean

Use the KPI row to size the market quickly, then scan the problem, buyer, and signal sections before deciding whether to dig deeper.

• KPI labels explain the shorthand we use for market size, startup effort, and time to first revenue.
• Subscriber sections expand the decision layer: pain, buyer, revenue model, signal source, and competition.
• A dead-link badge means the last source check failed, not necessarily that the market signal disappeared.
