Interviews a founder with the 1Sentence Deck questions, drafts three one-sentence investment theses, builds the deck story, and runs the Repeat Test. From https://1sentencedeck.com/
You are running the 1Sentence Deck method from 1sentencedeck.com. If you cannot open the site, use the questions below; they are the method's questions as published there. ## Inputs Company one-liner and stage: [COMPANY] Round, amount and the investors you are pitching: [ROUND] Anything I have already written (old deck, memo, notes): [EXISTING_MATERIAL] ## Interview Interview me using the method's questions, one at a time. Wait for my answer before asking the next question. Never invent numbers or facts for me; if an answer is vague, ask one follow-up for the specific fact. 1. Why are you doing this? 2. Who is it for? Who exactly has this problem, and how many of them are there? 3. Why are existing solutions not working, and how do you know? 4. How are you doing it? 5. How does this become a business? How do you reach customers and sell? 6. Does your math work? What are the cost and revenue signals? 7. If it's working, where is the proof? 8. Why you, when there are alternatives, other founders and giant companies that could build or copy this? 9. Can this become a huge outcome? 10. Is this the right time? 11. What do you need to get there? What is your next milestone, and how long will it take to prove this works? ## Thesis From my answers, draft three deck thesis candidates. Each is one sentence in investor language, not customer language: not what I sell, but why this becomes a huge company. Each must be repeatable (an investor could say it from memory tomorrow) and doubtable (specific enough to challenge). Give the trade-offs and let me pick or edit one. ## Story Write my answer to each question as one full sentence; these are the headlines. Keep the question order as the default story order and move a doubt earlier only when my situation calls for it (for example evidence early because nobody knows me). For each answer, propose where it lands: its own slide, a shared slide, or one line on another slide. Every question must be answered somewhere. Be honest about holes. If I gave no real proof for a question, say so plainly and tell me to either get the proof or shrink the thesis. Do not decorate weak claims. Write my ask as one line: raising X to achieve Y in Z timeframe. ## Repeat Test Show the cover first: the chosen thesis as the biggest thing in the deck. Then the ordered headlines with where each lands. Then check: does reading only the headlines re-prove the cover? What is the one sentence an investor repeats to their partner tomorrow? If it is not the cover, tell me to rewrite and say what is competing with it. Remind me to rerun this test myself one day after finishing the deck. ## Return at the end Chosen thesis, ordered headline list with placement, the one-line ask, an evidence-gap list (question, missing proof, get-it-or-shrink recommendation).

Company: Ledgerly, reconciliation software for independent veterinary clinics, seed stage Round: raising a seed round from vertical-SaaS investors Existing material: a 14-slide customer-facing deck; 9 paying clinics; founder ran a clinic's back office for six years
The assistant asks question 1 only and waits; later asks a follow-up when an answer lacks a number (for example how many independent clinics exist in the target market); drafts three investor-language theses that could be challenged; produces 11 one-sentence headlines with placements, possibly moving the proof (9 paying clinics) earlier; flags missing proof for the 'huge outcome' question with get-it-or-shrink advice; writes a one-line ask; and runs the Repeat Test. Illustrative expectation, not a recorded model run.
