Stress-test the plan first. Post-mortems arrive too late, dissent gets smoothed over in the room, and you stress-test your code far harder than your strategy. This book introduces the ASSAULT protocol, six skills that make adversarial thinking a daily habit for founders making irreversible bets. No tanks, no quarterly offsite, no pretend enemy. Red teaming becomes decision hygiene, not cosplay, so you stop being surprised by your own optimism.

Mark it up. Take it into the meeting. The book ## Adversarial Thinking for Operators Who Cannot Afford Surprise You wrote the strategy, so you defend the strategy. In every review you answer the objection instead of weighing it, explain away the soft number, and read the one chart that confirms the plan you already love. The market will not be so generous. It runs the experiment you keep refusing to run, and sends the invoice in lost quarters, not in feedback you can still act on. The usual answer is to gather more conviction: align the team, commit harder, treat doubt as a morale problem. Conviction feels like strength until the moment the blind spot becomes a crisis, and by then the only people stress-testing your strategy are your competitors. The Red Team Founder treats adversarial review as what it is in security and the military: a discipline, not a mood. It introduces the ATTACK framework (Assume failure, Target your assumptions, Take the adversary's seat, Audit the evidence, Counter your own defenses, Kill or commit), six moves that turn the scrutiny you reserve for rivals onto your own plan, on schedule, before the cost is real.

IntroductionIntroduction: Adversarial Thinking for BuildersThe plan did not fail because of bad luck. It failed because no one asked how it could fail.What you can do afterwardsYou will name the exact gap between how carefully you test your code and how lightly you test your plans — and walk away with a concrete method to close it.Use this chapter whenA failure arrives as a surprise that, in hindsight, had been visible for months. Or before the next big bet, when the room is convinced and no one is asking hard questions. 2. Chapter 1Beyond Military CosplayThe costume is easy. The method is harder. Most organizations adopted the costume and stopped there.What you can do afterwardsYou will leave this chapter knowing the difference between red teaming as performance and red teaming as decision hygiene — and you will have a working definition small enough to use before lunch on a Tuesday.Use this chapter whenYou feel a reflexive resistance to "red teaming" because it sounds like something a defense contractor or a McKinsey war-games team does — not something a three-person startup does at a whiteboard. 3. Chapter 2Assume FailureThe pessimist says the glass is half empty. The optimist says it is half full. The red team founder asks who drilled the hole in the bottom.What you can do afterwardsYou will run a prospective failure pass on an active plan before this chapter ends — and the failure list you produce will be more useful than a tenth iteration of the pitch deck.Use this chapter whenYou have committed to a plan in your head before you have tested it, or your team is generating enthusiasm faster than it is generating questions. 4. Chapter 3Surface DissentThe room agreed. Nobody said they agreed — they just stopped arguing. That is not consensus. That is the countdown.What you can do afterwardsYou will design a dissent slot for your next strategic meeting and a solo-founder equivalent that works without a team, so that the counter-argument reaches you before the market delivers it.Use this chapter whenA plan has been discussed and everyone seems aligned — especially when the alignment was fast, harmonious, and uncomfortable to question. 5. Chapter 4Stress-TestA weak objection knocked down is not a test. It is a ceremony. The plan needed a fight, and you gave it a sparring partner who throws on purpose.What you can do afterwardsYou will replace informal "devil's advocate" sessions with a disciplined technique for building the strongest counter-case your plan can face — one capable of revealing genuine structural risks, not just surface objections.Use this chapter whenYou are about to commit resources to a plan that has won internal agreement — especially when the team feels confident and the path forward looks obvious. 6. Chapter 5Update PriorsA stress-test that leaves your confidence unchanged is expensive venting. The whole point of running the exercise was to find out whether you were right.What you can do afterwardsYou will learn to translate adversarial evidence into concrete belief revisions — naming what moved, by how much, and why — so that ASSAULT produces genuine updates rather than the illusion of rigor.Use this chapter whenYou have just run a stress-test, pre-mortem, or dissent slot and are about to carry the original plan forward unchanged, as if the review had confirmed it rather than tested it. 7. Chapter 6LogMemory is not a recording. It is a story you tell yourself about what happened, revised every time you tell it.What you can do afterwardsYou will finish this chapter with a decision log template and one completed entry — an honest, time-stamped record of a decision that your memory will otherwise quietly rewrite.Use this chapter whenYou are about to commit resources to an irreversible bet, or you have just come out of an ASSAULT cycle and want the output to persist beyond the meeting. 8. Chapter 7TrainWhat you can do afterwardsYou will leave this chapter with a training loop — not a resolution to think more critically, but a concrete schedule that turns adversarial review from a one-time event into an automatic step you take before any significant commitment.Use this chapter whenYou have run one pre-mortem, or read two chapters on decision bias, and noticed that your thinking reverted to its prior state within ten days. 9. Chapter 8Pre-Mortems in PracticeA plan carries its failure inside it from the first slide. The pre-mortem is not pessimism — it is the surgical tool you use to find that failure before the market does.What you can do afterwardsYou will leave this chapter with a scripted, 30-minute pre-mortem you can run before your next launch, hire, or pivot — one that uses the six ASSAULT skills together for the first time and produces specific owners, not a list.Use this chapter whenA consequential, partially irreversible bet is between 48 hours and four weeks from commitment. Close enough that the failure assumption feels real; far enough that the outputs can still change the plan. 10. Chapter 9Daily Decision HygieneScale the method down, not the seriousness.What you can do afterwardsYou will match the depth of adversarial review to the actual weight of each decision — running micro-ASSAULT on reversible bets in under five minutes and knowing precisely when a decision has earned the full ASSAULT cycle instead.Use this chapter whenYou have run a pre-mortem and found it valuable, but the method still feels like something you deploy on launches and fundraises while the quieter decisions that shape each quarter pass without adversarial scrutiny at all. 11. Chapter 10The Red Team Founder SystemA plan that survives six skills in sequence is not the plan you started with. It is the plan the market will meet.What you can do afterwardsYou will run one complete ASSAULT cycle on a live strategic bet — from the selection criteria through the final log entry — and produce a plan that has been adversarially tested, belief-updated, and review-dated before you commit resources.Use this chapter whenYou have learned all six ASSAULT skills, practiced micro-ASSAULT on daily decisions, and run at least one pre-mortem. Now you want the full system on something that matters — a pricing change, a hire, a partnership, a pivot — not a workshop exercise. 12. ConclusionConclusion: Strong Plans Break EarlyThe founder who breaks a plan in a Tuesday conversation will not spend a Tuesday in March explaining to the board why nobody saw it coming.What you can do afterwardsYou will leave this chapter with one pre-mortem date blocked on your calendar, a clear picture of what the adversarial reflex looks like when it is fully installed, and a precise sense of how the six ASSAULT skills compound into something more valuable than their sum.Use this chapter whenYou have reached the end of the book with the method understood but the identity not yet claimed. The skills are in your toolkit. The reflex is not yet automatic. Something in this chapter should close that gap. Who it is for ## Who this book was written for The result is not a more confident founder defending the same plan. It is an operator who has already survived the attack in private, so the public version holds. If you would rather find your own blind spot on a Tuesday than have the market find it for you, this is the discipline you have been skipping. ### The reader it was written for The optimistic builder. Founder or operator aged 26–55 who ships fast, believes in the vision, and has been burned at least once by a plan that "could not fail." Intellectually honest enough to want adversarial methods; culturally allergic to corporate red-team theatre. Reads Kahneman, maybe Tetlock, probably skipped the war-game chapter in every other book. ### Also a fit for The technical cofounder pulled into strategy. Engineer who stress-tests systems but not roadmaps. Wants a protocol that feels like code review for decisions. ### What you will use it on - Run a pre-mortem before my next launch without facilitation training - Get cofounder/board to disagree productively - Stop repeating the same planning mistake quarterly - Build adversarial habit as solo founder - Connect red teaming to updating confidence, not just venting ### Probably not for you if - Professional offensive security red teamers - Chronic pessimists seeking validation for inaction - Enterprise risk officers needing SOX-aligned governance frameworks Editions ## Editions and specifications Edition Formats Chapters Pages Reading time ISBN (paperback) English The Red Team Founder In production 12 264 ± 4 hours — Dutch De red team oprichter In production 12 294 ± 4 hours — Both editions are written natively.
