What attributes would the worst, least desirable businesses have? This way of thinking is surprisingly helpful for figuring out what good businesses should look like.
Here’s what a high risk or bad business might look like (the more of these attributes a business has, the more difficult it will be to succeed):
- Very expensive to build the primary product or core service; difficult to find or rare components 
- Takes a long time to build the product or service before it can address a real customer need and unknown if it will ever fulfill the needs 
- Easy for other companies and teams to replicate the product or service 
- Marginal cost to produce product or service is very high 
- Can’t improve over time easily to prevent replication 
- Difficult to attract and retain customers 
- Long sales cycle that requires specialized expertise to sell product or service 
- Kills customers or harms society over time eg tobacco, environmental impact, etc 
- Hard for customers and others to understand benefits 
- Many other good companies doing it, very competitive 
- Not enough customers, limited number of people want to buy the product or service 
- Product or service costs customers money and returns little back eg it is a cost-center vs revenue driver 
- Team and leadership is dishonest 
- Core team doesn’t have right skills and/or motivation 
- No plan or possible growth opportunities 
- Highly leveraged with debts and limited free cashflow 
Ideally, you can eliminate and solve for as many of the negative attributes above:
