I was once told by my ex-CEO & co-founder — “Niraj, you don’t have business acumen.” It hurt like hell. Read the full story -> https://lnkd.in/gVRSQVqW So I spent my time and energy reverse-engineering how the best companies actually win. - 112 deep case studies. - 15 transparent quantitative models. - 33 chapters of no-BS, practitioner-first strategy. Today, I’m releasing it — Meet "The Strategy Engine" The deepest playbook ever built on Business Models, Unit Economics, Competitive Moats, and real-world Strategy. What you’ll get to know: - 50+ business model architectures torn apart (SaaS, Marketplaces, Fintech, D2C, Zero-Margin, Aggregators…) - Full value-chain breakdowns of Zoho, Atlassian, Zerodha, Meesho, Lenskart, Asian Paints, Jio, HDFC Bank and 100+ others - 15 live quantitative models (NRR, LTV:CAC, Payback Period, Moat Strength Score, Platform Flywheel KPI…) with actual formulas - 112 case studies — exactly 50% Indian, 50% global (because Silicon Valley templates alone don’t work in Bharat) - Every chapter ends with action items, decision trees, and questions you can run on your business TODAY - 300+ glossary terms, 20+ frameworks, 7 appendices This is the guide I wish I had before my first startup crashed and burned. I built it for every technical founder, operator, investor, or strategist who’s tired of winging it… and who refuses to ever again hear “you don’t have business acumen.” Strategy isn’t about being the smartest person in the room. It’s about asking the questions that expose bad ideas before they kill you. If you’re building, investing, or advising in 2025 and beyond — this is your new operating manual. Bookmark it. Share it with one founder who needs it. Come back to it every time you face a big decision. Let’s turn every “you don’t belong here” into “watch me build something unbreakable.”
