Most of what mattered was learned the hard way, in real time, under pressure. The world doesn't need more companies for the sake of it — it needs more companies with conviction.

About the book

An origin story.
An operating manual.

Part memoir, part playbook. Made in Fire is what every founder wishes they'd had on day one — distilled from two crises, twenty years and more than twenty companies that emerged from the ixigo ecosystem.

When you build a company, you are never building just a product. You are building people, instincts, habits, ways of thinking — and a kind of fire that can either forge something extraordinary or quietly burn everything down.

This book is for the founder who feels alone in the chaos. For the leader trying to grow without becoming hollow. For the builder who wants to create something durable, not just something flashy. And for the future founder who may still be inside a company today, learning how to think, how to own and how to build.

If you are holding this book, maybe you are trying to build one of those.

Sparks from the book

Lines that cut.

Twelve ideas from the manuscript. Each one earned the hard way.

"

Skills can be taught. Belief cannot be faked.

Ch 2 · Assembling the Avengers
"

Bad news must travel faster than good news.

Ch 1 · The Invisible Engine
"

Empathy isn't softness. It's strength — and one of the most underrated business strategies there is.

Ch 1 · The Invisible Engine
"

Integrity isn't about what you say. It's about what you do when it costs you something.

Ch 1 · The Invisible Engine
"

Creativity doesn't come from comfort. It comes from constraints.

Ch 1 · Scarcity as Catalyst
"

When the culture is alive, standards don't need enforcement. They spread by osmosis.

Ch 1 · People Are Your Culture
"

In moments of real crisis, when people genuinely care for each other, the org chart simply disappears.

Inside the book

Eight chapters. Forged in fire.

Culture, conviction, customers, AI and what every founder has to face when the dashboard goes dark.

01

The Invisible Engine

How culture drives start-up growth — and why it's built less by what you say than by what you tolerate.

02

Assembling the Avengers

Finding true believers for your start-up journey. Missionaries compound. Mercenaries corrode.

03

The User Is Your Universe

The only thing that matters. Why customer obsession is a discipline, not a slogan.

04

The Human Engine

People power and the art of building teams that think like owners.

05

Full-Stack Thinking

How breaking silos creates unstoppable teams — and why "that's not my job" kills companies.

06

Scaling Without Breaking

How to grow without losing your soul. Scale doesn't fix culture — it amplifies it.

07

Future-Proof Yourself

How to rebuild for the AI age — from first principles, before the market forces you to.

08

Beyond Profits

The founder's real scorecard. Scaling yourself without breaking — health, family, identity.

Advance praise

What builders are saying.

From sharp insights on culture, to an uncompromising focus on the user, to navigating scale and reinventing for the AI-native future — Rajnish captures the crucible moments of our journey vividly. In a world obsessed with speed, this book is a reminder to think deeply and play the long game.

Aloke Bajpai
Co-founder & Group CEO, ixigo

A raw, unfiltered playbook that shows how real companies aren't built with ideas, but forged in fire — through culture, conviction and relentless ownership.

Bestselling Author

Most founders underestimate the role of culture in building great companies — this book doesn't. It's a clear, experience-driven take on what actually compounds over time: ownership, customer obsession and the ability to scale without losing your soul.

The next best thing to going through the journey of building a high-growth company yourself is to read Made in Fire. The advice and knowledge here is otherwise only learned after years of effort.

Shailesh Lakhani
Investor & Partner, Ambition Capital

A practical guide that covers the principles that truly matter: how to assemble believers, how to keep your customer at the center of every decision, and how to grow as a leader. I recommend it to anyone serious about building something that lasts.
