Chapter 1 · Verdict
Score and bottom line
Promising, but prove demand first.
The catch: People agree stock goes missing, but almost nobody is shopping for a fix yet, so you could build something useful that no one buys.
Pre-sell 10 warehouses
+6 ptsOffer a 3-month pilot at $29 to 30 owners from the association list. Ten yeses proves demand.
Lead with the loss number
+3 ptsShow owners their own shrinkage in week one. Pain they can see sells.
Ship one integration, not five
+2 ptsPick the accounting tool your first ten use and do it well.
How the score adds up
Each part is scored out of 100, multiplied by its weight, then added. The parts add up to 64.
| Part | Score | Weight | Adds |
|---|---|---|---|
Demand Owners complain about stock loss, but few say they would pay to fix it. | 52/100 | 25% | 13.0 |
Market Plenty of small warehouses, and the category is growing. | 74/100 | 20% | 14.8 |
Competition Crowded at the top; the self-serve low end is thin. | 58/100 | 15% | 8.7 |
Model Software margins are high, but $49 needs low churn to work. | 66/100 | 15% | 9.9 |
Risk No licences needed; integrations are the hard part. | 72/100 | 15% | 10.8 |
Founder fit Your answers show you know warehouse work first-hand. | 70/100 | 10% | 7.0 |
| FounderOS Score (go line 70) | 64 | ||
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.

Synthesis
Real pain, reachable market, unproven willingness to pay.
Everything points the same way except one thing: nobody has paid yet. Settle that with a pre-sale before building.
Consistency check
- Medium
Market says owners are price-sensitive; Business model assumes $49 with no free tier.
Do this: Test a $29 starter plan alongside $49 in the pilot.
Chapter 2 · Market
Market
SOLIDThere are enough small warehouses to build a real business, if you can reach them cheaply. Next: Call five warehouse associations and ask how many members still count stock by hand.
Counts come from the business census; the share without software is an assumption to check.

Chapter 3 · Demand
What buyers say
Owners talk about the pain often, but rarely about paying to fix it.
“We do a full count every Friday and it never matches.”
A reply you could post: Same problem here. What do you do when the count is off — recount, or write it off?
“Bigger tools are built for 50-person teams.”
Quotes are copied exactly, with a link to the original. Suggested replies are ours: questions to learn more, never a pitch.
Chapter 3 · Demand
Proof of demand
NEEDS WORKInterest is steady, not rising. Complaints are proof of pain, not proof of purchase. Next: Ask 20 owners to pre-pay $29 for a 3-month pilot this month.
- Noise, not proof
Search interest flat for 5 years
Steady interest is fine, but it isn’t a wave to ride.
Change in search interest, 5 years±4% - Counts as proof
Complaint threads every week
The pain is real and recurring.
- Noise, not proof
No pre-orders yet
Until someone pays, demand is a guess.
Search interest in “inventory app”: Flat. Steady for five years.
Buyer panel
Simulated buyers, reasoned from the evidence above. They are assumptions, not real people: use them to plan interviews.
Owner of a 3-person warehouse
Would pay: Maybe · $29
“Wants to see it catch a real loss first.”
Ops lead at a small 3PL
Would pay: Yes · $49
“Needs a CSV export for clients.”
Marketplace seller with a storage unit
Would pay: No
“A spreadsheet is good enough for now.”
Chapter 4 · Competition
Competitors
Big tools own mid-size warehouses. Nobody owns the 2–5 person shop with a $29 self-serve plan.

Moat and cloneability
CRITICALNo moat yet. Your best bet is owning the small-warehouse niche before big tools care. Next: Decide what data you will collect from day one that a bigger tool can’t.
No yet
- Niche focusWeak
Works only while larger players ignore small shops.
- Shrinkage dataMedium
Benchmarks across many shops would be hard to copy.
How easy to copy: Easy. A counting screen and a weekly summary can be copied in weeks.

Financials and numbers check
WATCHYou break even around 40 customers. Cash runs thin if pilots convert slowly. Next: Keep monthly costs under $2,100 until 20 customers pay.

| Scenario | Month 3 | Month 6 | Month 9 | Month 12 | Assumption |
|---|---|---|---|---|---|

We re-did the key maths. Where it doesn't add up, it says so.
- ADDS UPBreak-even matches costs ÷ margin2,100 ÷ (49 − 6) ≈ 49 customers.
- DOESN'T ADD UPMarket and price agreeMarket says owners are price-sensitive; price assumes $49.

Go-to-market
Go where small warehouse owners already gather, and sell the loss number, not the software.
Your first 100 customers
- 30 owners from one association list, called directly
- Listing on the accounting tool’s app marketplace
- Referral credit: one free month per referral
Chapter 5 · Plan
Riskiest bet
CRITICALEverything rests on owners paying monthly for something they now do free. Next: Run the pre-sale before writing any code.
Small warehouse owners will pay $29–49 a month to stop losing stock.
- Why it matters
- If they won’t, there is no business, however good the app is.
- Cheapest test
- Thirty calls, one offer, count the pre-payments.
Chapter 5 · Plan
Interview playbook
Ask about the last time stock went missing, not whether they like the idea. Next: Book eight 20-minute calls this week.
Who to ask: Owners or ops leads of 2–5 person warehouses
Ask
- 1When did a count last not match? What did it cost?
- 2What do you use today, and what do you hate about it?
- 3Have you paid for anything to fix this?
Don't ask
Would you use an app that…?How much would you pay?
Opinions about the future are polite guesses. Ask about what people did last time.

- High
Owners won’t pay
Pre-sell before building.
- Medium

Own the small-shop niche fast.

Weekly loss summaries keep value visible.

Pivots
Two nearby ideas if the pre-sale fails.
Loss-audit service
Sell the counting as a monthly service first.
Consider it when: If owners want the result, not the tool.
3PL stock statements
Small 3PLs must send stock statements to clients.
Consider it when: If 3PLs convert better than warehouses.

Executive summary
One paragraph for a co-founder or adviser.
OpsLedger is a $29–49/month stock-counting app for 2–5 person warehouses. The pain is real and recurring, rivals are priced for larger teams, and margins are high. Demand is unproven: nobody has paid yet. The next step is a 30-call pre-sale; ten paying pilots is the go signal.

Investment memo

- Problem
- Small warehouses lose stock and count by hand every week.
- Solution
- Phone-based counting with a weekly loss summary, live in an afternoon.
- Market
- Tens of thousands of small US warehouses; the share without software is an assumption to check.
- Why now
- Marketplace sellers are renting more small storage, and margins are thin.
- Competition
- Suites priced from $199/month for 20+ staff; spreadsheets at the low end.
- Business model
- $29–49/month subscription, high gross margin, needs churn under 3%.
- Risks
- Unproven willingness to pay; easy to copy.
- The ask
- Not raising yet. Ten paying pilots first.

Glossary
Every term in plain words, and why it matters for you.

- 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.
- Gross margin
- The share of each sale left after direct costs. (Price − cost) ÷ price.

- Runway
- How many months you can keep going before the money runs out.
