Validated Problem Statement Template
📋 Template companion to the Mom Test synthesis section. Print after running 10 interviews. Fill in 30 minutes. Show to 2 advisors before building anything.
Validated Problem Statement Template - One Page, Five Sections
The synthesis sheet that turns 10 Mom Test transcripts into a build, pivot, or kill decision.
The Validated Problem Statement (one-page, 5 sections)
- Who has the problem - persona, vertical, strong-signal count
- What it costs them - hours per week, dollars per month, one sanity quote
- What they’ve tried - 3 workarounds + why each failed
- Why now - trigger event in last 12 months + market shift
- How big is the pain - average + strong-signal score → BUILD / PIVOT / KILL
Fill in order Mon morning. Send to one founder friend by Mon EOD.
Why this exists
A solo founder I spoke with last month sent 47 cold DMs to Twitter strangers complaining about their CRM. Twelve answered. Of the twelve, two said yes and ten said honest, paragraph-long no’s. She had spent six weekends collecting transcripts in a folder labeled notes. When she opened the folder to write the problem statement, she realized she had never named the persona, never tallied the strong signals, and never written the why-now. The ten no’s looked alike in her memory and contradicted each other on the page. Half of them were not even the persona she was building for. The synthesis took 90 minutes the first time she sat down to do it - and the decision the page produced was pivot to a different ICP rather than build. She kept the calendar she would have spent prompting Lovable and ran 5 sharper interviews instead. This template is the page she filled in.
How to use this
Block 90 minutes on a single morning. Print the template (or copy the markdown version below into a Notion doc). Bring all 10 interview transcripts, your handwritten Q4 scores, your emotional-flag counts.
The order matters. Score first, count second, write the page third. Write the page before scoring and you write the page you wished the calls had returned, not the page the transcripts actually support. The friction of writing the score before the prose is what stops you from talking yourself into the build.
Take the filled page to 2 readers within 48 hours. One advisor (a founder one step ahead, a fractional CTO, a board member). One peer (another founder still pre-launch). Ask each: “Would you argue with this?” If both nod, you’re done with Module 3. If either picks a fight on the persona, the cost, or the why-now, you have your next 5 interviews to run.
Total time budget: 30 minutes to write, 48 hours to circulate, 1 hour to incorporate the 2 advisor reads. Hard cap at 3 hours total. Beyond that, you’re polishing instead of validating.
The template - copy and paste
Use the markdown block below directly in Notion, or print the PDF version (the SVG version of the page is embedded in the Mom Test synthesis section).
================ VALIDATED PROBLEM STATEMENT ================

-------------------------------------------------------------
1. WHO HAS THE PROBLEM
-------------------------------------------------------------
Persona (named, specific):
____________________________________________________________
Industry / vertical (one, not many):
____________________________________________________________
Of 10 interviewees, this many confirmed the problem: ___ /10
Quote from a strong-signal call (one sentence, verbatim):
"___________________________________________________________"
-------------------------------------------------------------
2. WHAT IT COSTS THEM
-------------------------------------------------------------
Time per week: _____ hours
Money per month: $_______
Sanity cost (one concrete moment from a transcript):
"___________________________________________________________"
Cost is consistent across the 10 calls (Y/N): _____
-------------------------------------------------------------
3. WHAT THEY'VE TRIED
-------------------------------------------------------------
Workaround 1: ______________________ Why it failed: _______
Workaround 2: ______________________ Why it failed: _______
Workaround 3: ______________________ Why it failed: _______
Current spend on workarounds: $_______ /month (average)
The workaround is the budget your product would replace.
Name the closest competitor: ______________________________
-------------------------------------------------------------
4. WHY NOW
-------------------------------------------------------------
Trigger event (what changed in last 12 months):
____________________________________________________________
Market shift (regulation, AI cost, platform, behavior):
____________________________________________________________
If this section is empty, the why-now is missing.
A missing why-now usually means the idea is good and the
timing is wrong - park it, run a smoke-test landing page,
revisit in 6 months.
-------------------------------------------------------------
5. HOW BIG IS THE PAIN
-------------------------------------------------------------
Average pain score across 10 calls (Q4 + emotional flags):
______ /10
Strong signals (score 7+ with 3+ emotional flags): ___ /10
Decision based on strong-signal count:
[ ] 7 or more → BUILD. Move to Module 4.
[ ] 4 to 6 → PIVOT. Run 5 sharper interviews.
[ ] Fewer than 4 → KILL. Find a different problem.

============================================================
What good looks like vs what bad looks like
Section 1 - Who has the problem
Bad: “Founders and small business owners who need help with productivity.”
Good: “Pre-seed B2B SaaS founders running their own bookkeeping reconciliation between Stripe, QuickBooks, and a Google Sheet. 8 of 10 interviewees confirmed (industry: vertical SaaS, May 2026 sample). Quote: ‘Last Tuesday at 9pm I spent 40 minutes copying Stripe payouts into my QuickBooks ledger. I called my CFO. She did it in 90 seconds. I felt stupid.’”
The good version names the persona by stage, industry, and the specific workflow. It puts a number on the strong-signal count and includes one verbatim quote. A peer can argue with it: “Are you sure pre-seed is the right segment? Wouldn’t seed-to-Series-A be the buyer?” That argument is exactly the value. The bad version is too broad to argue with, which is why advisors nod and the post-launch failure mode is crickets.
Section 2 - What it costs them
Bad: “It costs them time and money. It’s a significant pain point.”
Good: “6 hours per week. £800 per month in CFO contractor time. One founder I spoke with paid $1,500 for a SurveyMonkey panel after the bookkeeping pain spiked - the panel returned 47 useless responses and she did the work herself anyway. Cost was consistent across 8 of 10 calls; 2 were running their own pre-revenue and had zero contractor spend (but 12 hours of personal time per week).”
The good version uses real numbers from transcripts. The £1,500 panel anecdote is from a specific person. The 6 hours and £800 are averages with the sample’s variance noted. The bad version is unfilled white space dressed up as prose.
Section 4 - Why now
Bad: “AI is changing everything. The market is ready.”
Good: “AI inference cost for the document-classification step fell from $0.04 to $0.001 per call between 2024 and 2026 - the unit economics flip at $9/month per seat. Stripe’s automated tax product (launching Q1 2026) signals SMB finance is being deconstructed feature by feature, but bookkeeping reconciliation at pre-seed founder budgets is still manual.”
The good version names the specific cost number, the specific competitor’s specific product, and the specific gap. It cites a competitor signal that supports the timing rather than refuting it. The bad version is filler that means nothing and helps no one.
What to do after
The decision the filled page makes for you:
- BUILD if: 7+ strong-signal calls (score 7+ with 3+ emotional flags), a named workaround the customer is already paying for, and a named why-now from the last 12 months. Move to Module 3 Product Brief.
- PIVOT if: 4-6 strong signals, OR the pain is real but belongs to a different persona than you targeted (e.g., you interviewed founders but the pain lives with their CFOs). Run 5 sharper interviews with the corrected ICP, then refill this page.
- KILL if: fewer than 4 strong signals OR no workaround surfaced in the 10 interviews. Find a different problem and write the 200-word post-mortem below.
Then walk the page through these four moves:
- Get 2 advisor signatures within 48 hours. Email the page as a PDF. Ask: “Would you argue with this problem statement?” One sentence response is enough. If both say no, you’ve passed Module 2’s checkpoint and you move to the Module 3 Product Brief next.
- If you landed in the BUILD lane (7+ strong signals), run the 3 pre-orders test before writing code. Email your 5 strongest-signal interviewees. Ask each for a £500 deposit, a signed letter of intent, or a paid waitlist slot. Three yes-and-paid out of five = build. Zero yes = the 7+ scores were politer than you thought, slide back to pivot.
- If you landed in the PIVOT lane (4-6), pick the cleanest segment and run 5 sharper interviews using the Mom Test interview script again. Don’t rerun the same 10 - they’ve already given you their honest answer. New segment, new interviews, one week.
- If you landed in the KILL lane (fewer than 4), write a 200-word post-mortem to your future self. What ICP did you pick wrong? What why-now did you assume that wasn’t true? What workaround did you not learn about until interview 7? The post-mortem is the most valuable artifact from a kill round - it stops you from picking the same wrong target again next quarter. The stop-AI-obsession validation post has the long version of the discipline.
Skip the synthesis page and start prompting straight away and you’re the founder who, six weeks later, posts a salvage or rebuild question about a working MVP nobody wants. The page is cheap. The build round you skip because of the page is the expensive thing you avoid.
