It is well worth the time and the effort spent to navigate through this book when starting a company or investing your time and effort in a new idea. OPTICS will help founders challenge their own assumptions and take a more systematic approach before overbuilding.

Ninety per cent of startups fail. The industry treats this like gravity, a law of nature founders have to accept. This book argues it's not inevitable.
Drawing on founder interviews and field studies, Natasha Gorobinskaya traces most failures to identifiable gaps in customer understanding and validation, then offers a way to close them. Her OPTICS method gives founders a clear, easy-to-follow structure, drawing on Michael Margolis's Bull's Eye Customer Sprint and her proprietary Experience-Value Framework, and lands on a traceable product-market fit evaluation. AI-assisted when you choose, for early-stage and mature ventures alike.
Why most startups fail, where founders miss their customer, and why Customer Development so often goes unapplied.
Observation, Problem, Targets, Insight, Calibration, Strategy — the six moves from first signal to validated strategy.
Evaluating outcomes, running a five-day OPTICS Sprint, and how OPTICS sits alongside other frameworks.
Written for the accelerators, studios, and incubators building the next wave of companies, and for the founders inside them who suspect the standard startup playbook is incomplete. Coaches, mentors, and investors who want a faster, evidence-based way to evaluate ventures will find it just as useful.
