Concept
Worth-solving problems are frequent, urgent, expensive (money or time), and owned by someone with budget or authority.
Why it matters
Interesting problems entertain founders. Expensive problems fund companies.
Action steps
- 1Shadow or interview 5 people in the workflow; list moments of swearing or spreadsheet hell.
- 2Estimate annual cost of the status quo for one customer.
- 3Check whether a budget line already exists (tools, agencies, headcount).
- 4Prefer problems that reoccur weekly over annual ‘strategy’ pain.
Done when
You can quantify the problem’s cost for at least one real account.
Metrics
- · $ or hours wasted / month
- · Frequency
- · Number of people affected
Anti-patterns
- · Building for yourself only without check for willingness to pay
Follow the money already being spent on workarounds — that’s your pricing ceiling signal.
