From "I built a thing" to "people are paying for it" — frameworks for technical founders.
You wrote the code. You wired the auth. You shipped the landing page. A hundred people signed up free. Two asked when the paid tier launches and never came back. The MRR chart is flat. Welcome to the gap — the gap between *built* and *bought* is wider than any engineer-founder expects, and it has nothing to do with your code quality.
This pack is thin on purpose: six chapters and five worksheets you can work through in a weekend. It targets one specific moment — you have a working product, zero or near-zero paying customers, and you need to figure out, without burning six more months, who pays, why now, how much, and how they find you. No "10x your runway" cringe. No generic growth advice that assumes you have a marketing team. The frameworks are battle-tested across multiple shipped products; the work is real and slow.
Inside: Chapter 1 (the four questions every product fails on), Chapter 2 (vision → killer features → user profiling → funnel), Chapter 3 (the 3-question test for features people will actually pay for), Chapter 4 (founder-led sales: DM 50, expect 3), Chapter 5 (pricing without data), Chapter 6 (growth experiment log). Plus five fill-in worksheets and founder email templates. Read in ninety minutes; work the worksheets in an afternoon.
The four questions every product fails on: who specifically pays, why now, how much will they pay, how do they find you. Why engineers are biased toward the first 30% of problems and against the 70% that contains the money.
Four stages, in order, each narrowing the next. Vision (one sentence in a tweet), killer features (three things), user profiles (who pays for which), funnel (how they find, try, pay). B2B and B2C worked examples.
Question 1: Would they pay for this feature alone? Question 2: Would they recommend it unprompted? Question 3: Would they leave a competitor for this? How to validate without building (smoke tests, manual prototypes, pre-orders).
Founder-led DM outreach (50 DMs → 3-5 replies → 0-1 paying customer), cold email patterns, community presence on Reddit/IH/HN, content as lead-gen. What does NOT work in the first 100 (paid ads, PR, SEO, affiliates).
Anchoring techniques (vs. substitute, high anchor), Van Westendorp willingness-to-pay survey (20-30 responses), the 3-tier rule ($9, 3-5x, 5-10x), the free tier trap, pre-launch pricing experiments.
What to measure at <100 / <1k / <10k users. The experiment template (hypothesis, metric, duration, result, decision). Anti-pattern: vanity metrics. Sustained compounding at 12-18 months of consistent logging.
Vision + killer features, user profile (one per user type), pricing survey, experiment log (append-only), founder email templates (cold, follow-up, churn-recovery, win-back).
Chapter 1 (The Gap) is distributed freely. It shows you the four questions and why engineer-shipped products fail on them. If it doesn't justify the price for the rest, don't buy.
Yes — exactly. That is the audience. The pack is for the moment after the build, before product-market-fit. If you have not shipped yet, focus on shipping first; come back when you have a working product and a flat MRR chart.
Especially Chapter 5. The "free tier trap" section is the core argument — free tiers work for a narrow set of business shapes and are an expensive default for everyone else. The chapter helps you decide whether your free tier is structural or just a habit.
Both. The framework is the same; the channels and price points differ. Chapter 2 includes one B2B and one B2C worked example. Chapter 4 (traction) leans slightly B2B because founder-led DMs are concrete to demonstrate, but principles port to B2C with substitutions (Twitter threads instead of LinkedIn DMs, etc).
Less so. Each worksheet references the book's frameworks (the 3-question test, the Van Westendorp survey, the experiment-log decision rule). Reading the relevant chapter takes ten minutes and is what makes the worksheet outputs defensible.
v1.x point releases (v1.1, v1.2) are free to v1.0 buyers — redownload from your purchase page. Hypothetical v2.0 would be a separate SKU. The changelog tracks which chapter changed in each release.
30 days, no questions. If the book or worksheets don't land for you, email info@shippedstack.com for a full refund. Single-seat license — please don't share the files.
6 chapters, ~5,500 words. Read the whole thing in ninety minutes. Work the worksheets in an afternoon. By the end you will have written answers to the four questions, not vibes.
