Chapter 1 · Verdict
Score and bottom line
Needs work: the returns loop decides everything.
The catch: Each mailer must come back several times to beat a single-use one on cost, and you don’t yet know if customers will return them.

How the score adds up
Each part is scored out of 100, multiplied by its weight, then added. The parts add up to 56.
| Part | Score | Weight | Adds |
|---|---|---|---|
Demand Shops like the idea; few have switched. | 55/100 | 25% | 13.8 |
Market Many online shops, thin margins. | 62/100 | 20% | 12.4 |
Competition Cheap single-use mailers are the real rival. | 50/100 | 15% | 7.5 |
Model Return logistics eat the margin. | 52/100 | 15% | 7.8 |
Risk Sourcing is doable; the returns loop is hard. | 60/100 | 15% | 9.0 |
Founder fit First physical product; you have shop-owner contacts. | 55/100 | 10% | 5.5 |
| FounderOS Score (go line 70) | 56 | ||
Why these weights
- Demand 25%: No real need is the most common reason startups fail.
- Market 20%: Size and timing set the ceiling.
- Competition 15%: How hard it is to win share.
- Model 15%: Whether the money works.
- Risk 15%: Regulatory, technical and execution risk. Higher means safer.
- Founder fit 10%: Read from your answers alone, so it carries the least weight.

Glossary
Every term in plain words, and why it matters for you.
- MOQ
- The smallest batch a factory or supplier will make for you.
- Why it matters: Decides how much cash you need before you sell a single unit.
- Unit cost
- What it costs to make one item, before shipping and duties.
- Why it matters: The starting point for your margin.
- Landed cost
- The full cost of one item once it reaches you: making it, shipping, duties and fees.
- Why it matters: Your real cost per unit. Price below it and you lose money on every sale.
- Lead time
- How long from placing an order to having stock in hand.
- Why it matters: Long lead times tie up cash and make running out of stock costly.
- TAM
- Everyone in the world who could ever buy this, in money per year.
- Why it matters: Shows the ceiling. A tiny TAM caps how big this can get.
- SAM
- The part of the TAM you could actually reach with your product, price and location.
- Why it matters: This is the market you are really competing in.
- SOM
- The slice of the SAM you could realistically win in the first few years.
- Why it matters: Plan your money around this number, not the TAM.
- CAC
- What it costs, on average, to win one paying customer.
- Why it matters: If it costs more to win a customer than they pay you, growth loses money.
- LTV
- How much money one customer brings in before they leave.
- Why it matters: Tells you how much you can afford to spend to win each customer.
- LTV:CAC
- Lifetime value divided by the cost to win a customer. 3:1 is a common healthy target.
- Why it matters: Below 1:1 you lose money on every customer.
- COGS
- The direct cost of what you sold: materials, making it, delivering it.
- Why it matters: Revenue minus COGS is what you have left to run the business.
- Gross margin
- The share of each sale left after direct costs. (Price − cost) ÷ price.
- Why it matters: Low margins leave little room for marketing, salaries and mistakes.
- Burn
- How much more money goes out than comes in each month.
- Why it matters: Divide your cash by it to see how long you can keep going.
- Runway
- How many months you can keep going before the money runs out.
- Why it matters: The deadline for proving the idea works or raising more.
- Break-even
- The point where money in equals money out.
- Why it matters: Past it, the business pays for itself.
- Churn
- The share of customers who stop paying each month.
- Why it matters: High churn means you keep refilling a leaky bucket.

- ICP
- A precise picture of the customer who needs this most and pays fastest.
- Why it matters: Everything gets cheaper when you sell to the right person first.
- Go-to-market
- How you reach your first customers and get them to buy.
- Why it matters: Most good products fail on distribution, not on the product.
- Pre-mortem
- Imagine it is a year from now and the idea failed, then list why.
- Why it matters: Finds the risks you would otherwise only see in hindsight.

- Why it matters: Shows who can push your prices down or your costs up.
