Customer Success by Nick Mehta, Dan Steinman, and Lincoln Murphy
Published by three Gainsight executives and widely regarded as the field’s foundational text, this book defines what customer success is, why it emerged from the SaaS business model, and how to build a functional CS operation. It covers customer segmentation, health scoring, QBRs, executive sponsorship, and the relationship between CS and revenue retention. If you read one book before anything else on this list, it’s this one.
Pros: Comprehensive foundational coverage, authored by industry pioneers, widely used as CS team onboarding reading Cons: Written primarily for enterprise SaaS context, some frameworks may feel heavy for early-stage companies
The Startup’s Guide to Customer Success by Jennifer Chiang
Jennifer Chiang wrote this book for the CS practitioner who is building the function at a startup rather than maintaining it at an enterprise. The advice is pragmatic and resource-aware - how do you handle 50 accounts when you’re a team of one? How do you build a playbook when you have no historical data? Chiang’s framework helps early-stage CS teams prioritize effort and prove value before the company is ready to invest in CS infrastructure.
Pros: Written specifically for startup and early-stage context, actionable without requiring large teams or budgets Cons: Less applicable once a CS function matures past the early growth stage, lighter on advanced strategy
Farm Don’t Hunt by Guy Nirpaz
Nirpaz, CEO of Totango, frames this book around a single compelling shift: moving from a hunter mentality (always pursuing new logos) to a farmer mentality (cultivating and growing existing customers). The farming metaphor holds up throughout - nurturing relationships, identifying expansion signals, and building programs that grow revenue from the installed base rather than constantly filling a leaky bucket with new sales. This is the book for anyone who needs to make the internal case for investing in CS over pure sales acquisition.
Pros: Clear, memorable framework, strong case for CS ROI, short and readable in a single sitting Cons: More conceptual than tactical, needs supplementary reading for implementation specifics
Never Lose a Customer Again by Joey Coleman
Coleman’s framework tracks the first 100 days of a customer relationship across eight distinct phases - from initial excitement through potential disillusionment to deep commitment. The book is unusually specific about the emotional states customers experience during each phase, and it provides scripts, tactics, and program ideas for navigating each one. CS teams focused on reducing early churn will find this book immediately actionable.
Pros: 100-day framework is concrete and immediately implementable, emotional customer journey lens is rare and valuable Cons: Skews toward high-touch B2B relationships, some tactics require significant investment to execute properly
Outcomes Over Output by Josh Seiden
Seiden’s book is technically a product management text, but it belongs in every CS professional’s library because it provides the intellectual foundation for outcome-based conversations with both customers and product teams. The core argument - that shipping features is not the goal, and that changing customer behavior is - directly equips CS managers to lead business reviews focused on impact rather than product updates. It reframes the CS value conversation in terms that resonate with executives.
Pros: Reframes CS-product relationship around outcomes, short and immediately applicable, useful for cross-functional alignment Cons: Not a CS-specific book, some readers may need to actively translate product concepts to CS workflows
What to Look For
Your experience level: Absolute beginners should start with Mehta et al. before anything else. Mid-level practitioners looking to deepen retention expertise should go to Coleman. CS leaders making strategic investments should read Farm Don’t Hunt and Outcomes Over Output.
Your company stage: Early-stage companies under 50 employees with nascent CS functions will get more from Chiang’s startup guide than from enterprise-focused frameworks.
Your immediate problem: Match the book to your current challenge. High churn in the first 90 days? Read Coleman. Fighting for CS investment from leadership? Read Nirpaz. Struggling to connect CS metrics to product decisions? Read Seiden.
Application vs. theory: Some CS books are primarily conceptual. Balance your reading with tactical books that give you repeatable frameworks and templates you can deploy in the next quarter.
Final Thoughts
Start with Mehta, Steinman, and Murphy if you’re building foundational knowledge - it’s the CS field’s equivalent of a university textbook. Chiang is the pragmatic second read for startup practitioners. Nirpaz gives you the narrative to sell CS investment internally. Coleman provides the most tactical 100-day retention framework available in print. Seiden rounds out the stack by aligning how you think about customer outcomes with how your product team does. Read them in roughly this order and you’ll have a complete picture of the function from first principles to advanced strategy.
Frequently asked questions
What's the best customer success book for someone completely new to the field?+
"Customer Success" by Nick Mehta, Dan Steinman, and Lincoln Murphy remains the most comprehensive entry point for CS newcomers. It covers why the function exists, how to build a team, and how to measure outcomes. It was written for a SaaS context but the principles apply broadly to any subscription or recurring revenue business model.
Which customer success book is best for early-stage startups?+
"The Startup's Guide to Customer Success" by Jennifer Chiang is written specifically for founders and small CS teams who don't yet have the infrastructure of an enterprise CS organization. It addresses prioritization with limited headcount, building playbooks from scratch, and making the case for CS investment internally - challenges that are invisible in books written for mature CS organizations.
How is customer success different from customer support?+
Customer support is reactive - it addresses problems after they occur. Customer success is proactive - it works to ensure customers achieve their desired outcomes before problems arise. CS teams focus on adoption, health scores, renewal risk, and expansion revenue. The books on this list reflect that proactive orientation, with onboarding, retention frameworks, and product alignment as central themes.
