Most pre-seed founders drift for 9 months because nobody put a clock on the work. Put the clock back on. ## Weeks 1–4: Buyer interviews, not user interviews Talk to 30 people who would write the cheque — not 30 people who would use the product. The buyer and the user are often different humans with different incentives, and only one of them controls budget. Ask: what is currently broken, what have you tried, what stops you fixing it, and what is the cost of leaving it broken for another year? By week 4, you should have one painful, recurring, expensive problem named in the same language by at least 8 of the 30. If you do not, the idea needs a re-cut, not a build. Per CB Insights' 2024 startup post-mortem analysis, 'no market need' remains the single most cited reason startups fail at 35% — ahead of running out of cash (38% combined with funding issues) and being out-competed (20%). Skipping the buyer interview phase is the most expensive shortcut in early-stage. ## Weeks 5–8: Sell the slide, then build the slide Build a one-page proposal — not a product. Take it to the 8 buyers from phase one and ask: 'if this existed exactly like this, would you pay £X for it, when, and what would have to be true?' You are not selling — you are pricing the pain and timing the budget cycle. Two of the eight will say 'when can I have it?'. That is your design partner. The proposal becomes the spec. Now build the smallest version of the proposal that gets one of them to send a PO. ## Weeks 9–12: Cash, not pilots Free pilots are diagnoses, not validation. By week 12, the milestone is one paid contract — even if it is £500 — from a stranger you did not know in week 1. Paid is the only signal that survives a board meeting. If week 12 closes with no paid contract, do not extend by another 90 days on the same hypothesis. Re-cut the buyer, the problem or the offer. The clock is the discipline. Resetting it is allowed; ignoring it is fatal.
