Eric Ries's Lean Startup taught the world to build, measure and learn. Lean Innovation 3.0 keeps everything that worked — and fixes the loop that kills idea-stage startups: Build–Fail–Pivot–Build–Fail–Pivot, until the runway runs out.
Startup Success = Problem Validation × Design Partners × MSP × AI Acceleration
Multiplied, not added. If any factor is near zero — the product is near zero.
Not motivation. Frameworks, checklists and decision gates for every stage: Idea → Pre-Start Marketing → MSP → Local PMF → Global PMF.
Five forms of the first sale — Deposit, Concierge, Pilot, Service, Hybrid — and how to choose yours.
10 operational steps from segment analysis to the first paid deal — all before a line of code.
How a waitlist becomes paying co-builders: rewards, pricing, and the three-beat conversion.
Why 80% say "no" regardless of your product — and how to put irrationality to work (Kahneman, Nobel 2002).
A one-page artifact: hypothesis, team gap-map, competitor map and a 60-second elevator pitch.
Score segments by Problem × Solution × Monetization — and pivot with discipline, not panic.
LOI → paid pilot → paid contract, with real conversion benchmarks at every step.
The Sean Ellis 40% test, CAC/LTV, cohort retention curves and the repeatable growth engine.
Persona simulation, interview clustering, funnel analytics — months of work compressed into weeks.
Every one of them held a paying customer before holding a finished product.
"What none of them had was a system that forced the cheap question before the expensive answer."
"Sold, then built — that sequence is the sharpest line between the few who survive and the many who die."
CHAPTER 1 · THE $500 BILLION GRAVEYARD"A credit card charge is not a survey response; it cannot be explained away by politeness or curiosity."
CHAPTER 6 · MSP: THE FIRST SALES"You cannot out-argue a system with emotion, but you can defeat emotion with a system."
CHAPTER 2 · PROSPECT THEORY"Advisors tell you what they think the market wants. Design partners are the market, telling you by what they do."
CHAPTER 9 · DESIGN PARTNERS"Two billion dollars cannot buy you out of an unvalidated hypothesis. It can only let you discover the truth more slowly and more publicly."
CHAPTER 10 · A GRAVEYARD TOURAccelerators take traction. This book takes you from zero — and builds the traction they want to see.
You have an idea and no playbook. This is the route from idea to first paying customer, step by step.
New vertical, old risks. Validate the new market before you commit the next two years to it.
One shared language, one base of artifacts — instead of five opinions about what "validated" means.
No team, no MVP, no traction. The AI-accelerated workflow makes the method practical for one person.
Igor Peer is the creator of the Lean 3.0 methodology and the founder of Startup Mastery, a global venture studio. For more than twenty years he has worked at the heart of the innovation economy — as a founder and CEO, and as a business development executive who raised capital and built partnerships with companies such as Google, IBM, and Sony.
Today he directs a government-backed startup accelerator in Israel, teaches and advises at Nova SBE in Portugal, and mentors international startup and innovation programmes. This is his second book — the story began in 2018 with his first book inside Startup Mastery, the foundation on which Lean 3.0 is built.
One bad build costs six months and $100,000. The system that prevents it costs less than dinner.
