In ‘The Science of Scaling: Using Data to Decide When – and How Fast – to Scale Revenue,’ Mark Roberge explores the two critical questions in any startup, product launch, or market expansion: are you ready to scale sales, and how fast should you do it?
Many decisions rely on intuition, recent funding, or comparisons with other companies, but The Science of Scaling offers a structured, data-driven alternative.
Mark Roberge, Founding Chief Revenue Officer at HubSpot, Senior Lecturer at Harvard Business School, and Co-Founder of Stage 2 Capital, draws from 25 years of experience and observations across hundreds of startups.
The book outlines five common pitfalls that cause revenue scaling to fail:
- prioritizing top-line growth too early instead of consistent customer value,
- using vague or non-data definitions of product-market fit,
- misunderstanding go-to-market readiness before sales hires,
- rushing sales team expansion without pacing, and
- mistaking short-term gains for durable advantages.
It targets founders preparing to scale, executives managing growth, investors evaluating portfolio companies, and general managers launching new products. On Amazon, the 1st edition holds a 5.0 out of 5-star rating from 18 reviews and ranks as the #1 bestseller in Business Development.
What You Will Learn
You will learn a measurable, stage-based framework to assess scaling readiness and pace using your own company’s data rather than external benchmarks or gut instinct.
The book defines three sequential stages of scaling, each with quantifiable indicators for product-market fit and go-to-market fit.
You will gain tools to identify when these fits are achieved and stable, then determine optimal hiring speed to avoid breaking them.
Roberge explains how to monitor leading metrics that signal loss of fit during acceleration, so you can adjust before damage occurs.
You will discover why premature or mismatched scaling efforts fail and how to build go-to-market systems grounded in internal performance evidence.
This approach helps you scale as quickly as possible while preserving retention, unit economics, and sustainable growth. It serves as a practical guide for making irreversible decisions with clarity, particularly useful if you lead a startup, advise portfolios, or drive new market entries.
