Startup problems.
A startup can only have four problems:
1. People in large numbers are not ready to pay for what we do.
2. We cannot make money on one sale, because the cost of attracting a buyer is too high.
3. We cannot attract external financing because we provide too low a return on it (loans or investments).
4. We do not have the necessary abilities and competencies to create the MVP.
