Nitin Kartik book tops 70-week Amazon bestseller run as AI changes marketing

Princeton-area author and Caribou Strategic CEO Nitin Kartik says his book Product Marketing Wisdom has crossed 70 weeks as an Amazon bestseller, tapping demand for human-centered marketing guidance as AI reshapes the field. The book blends customer insight, messaging and go-to-market strategy with AI to help leaders grow in more competitive markets.

Why it matters: - AI is speeding up content creation, market research, personalization and customer engagement. - Kartik’s message is that the human parts of marketing still drive growth: empathy, positioning, storytelling and judgment. - The book’s momentum suggests leaders want practical guidance on what AI can automate and what still requires human decision-making.

What happened: - Princeton-area bestselling author Nitin Kartik, CEO of Caribou Strategic, said Product Marketing Wisdom has spent more than 70 weeks as an Amazon bestseller. - The milestone comes as companies rethink how to use AI across marketing and go-to-market work. - Kartik wrote the book as a practical resource for marketers, founders and business leaders. - Product Marketing Wisdom is available on Amazon: More information

The details: - The book draws on insights from more than 100 product marketing leaders. - It covers market research, competitive analysis, positioning, messaging, go-to-market strategy, storytelling, sales enablement, cross-functional collaboration, KPIs, AI, technology and personal development. - Kartik frames product marketing as a strategic discipline that connects customer needs, product value and business outcomes. - The book is meant to help readers turn customer understanding into stronger positioning and clearer growth strategies. - Kartik is a 2X bestselling author. - Readers and leaders cited in the release praised the book’s value for product marketers, revenue teams and people entering the field. - The release quoted praise from Ryan Sorley of DoubleCheck Research, Partho Ghosh of Magnet Forensics, Catie Ivey of GrowthZone AMS, Madhav Bhandari of Storylane and Robert Kaminski of FletchPMM. - Kartik said the field needs deeper customer understanding, clearer stories and stronger strategic thinking as the market gets noisier and more competitive.

Between the lines: - The release positions product marketing as a company-wide discipline, not just a function for marketing teams. - Kartik argues that AI may make execution faster, but differentiation will depend more on the quality of thinking behind the message. - That framing reflects a broader shift in marketing: tools are multiplying, but trust and clarity remain hard to automate. - The book’s sales streak also doubles as proof of demand for leadership content that blends AI with timeless business skills.

What's next: - Kartik expects product marketing to matter more for CEOs, founders, sales leaders, product leaders and customer success teams. - He says the core questions will remain the same for businesses: who they serve, what problem they solve and why customers should care. - The book is positioned as a playbook for sustainable growth in AI-driven markets. - Kartik and Caribou Strategic continue to promote the book alongside the company's broader author and launch services.

The bottom line: - Kartik’s pitch is simple: AI can help with speed, but growth still depends on human clarity, customer insight and strategic judgment.
