Dan Martell, Matt Verlaque, Johnny Page, Marcel Petitpas, and Patrick Campbell

Software as a Science (2024) is a collaborative work by five practitioners who have collectively coached, built, or analyzed hundreds of SaaS companies. The book represents the distillation of their pattern-matching across a wide range of SaaS businesses at different stages.

The Authors

Dan Martell — Founder of SaaS Academy, one of the leading coaching programs for B2B SaaS founders. Previously built and sold multiple software companies. Known for his operational playbooks for SaaS growth. Author of Buy Back Your Time (2023).

Matt Verlaque — Co-founder of UpLaunch, a fitness technology SaaS company that grew to significant scale before being acquired. Now a partner at SaaS Academy.

Johnny Page — Partner at SaaS Academy. Specialist in customer success and onboarding strategy for SaaS companies.

Marcel Petitpas — CEO of Parakeeto, a profitability analytics platform for agencies. Known for his work on SaaS metrics and unit economics.

Patrick Campbell — Co-founder of ProfitWell (acquired by Paddle), a SaaS metrics and pricing intelligence platform. One of the most cited researchers on SaaS pricing, retention, and expansion revenue.

Intellectual Signature

The book’s core claim is that SaaS companies are fundamentally math problems with determinate solutions, not creative or cultural entities that defy systematic analysis:

“Your company is a math problem. And math problems have solutions.”

This posture — empirical, systematic, pattern-based — runs through every chapter. The authors are explicit that the specific problems facing any SaaS company at any stage are predictable, because SaaS companies follow predictable patterns regardless of their surface-level differentiation.

“All software companies taste like chicken. They’re selling different products, but 80% of what they do is pretty much the same.”

Key Ideas

The Growth Ceiling and Three Levers

See saas-growth-ceiling-and-three-levers for full treatment.

The framework reduces SaaS growth to four variables (current customers, new customers per month, monthly churn rate, monthly ARPA) and three levers (Acquisition, Retention, Expansion). The power of the framework is its determinism: given these four numbers, you can calculate exactly when your company will stop growing.

Sequencing = Success

One of the book’s most operationally significant principles:

“You can do the right things in the wrong order and still lose. Sequencing = Success.”

The prescribed sequence in most situations: fix Retention before investing in Acquisition. A high-churn company that accelerates sales is accelerating toward its Growth Ceiling, not away from it.

The Marketing Channel Stack

The book’s marketing framework applies the same sequencing logic to channel development: master one macro channel (Earned Media, SEO, Paid Ads, or Cold Outbound) before adding the next. Each channel is fully “mature” when it has documented process, dedicated people, a measurable scorecard, a testing cadence, and a CAC Payback Period under 90 days.

“Every channel you stack will increase your growth faster than the last.”

The CAC formula:

“CAC Payback Period = CAC / (ARPA × Gross Margin)”

Target: under 90 days for self-funded companies.

Top-of-Funnel Content Strategy

One of the book’s most quoted marketing insights:

“Your top-of-funnel content must be intellectually divorced from your product, but emotionally wed to it.”

The application: create free content that teaches your target customer how to think about the problems your product solves, without making the content about your product. When readers understand the problem correctly (in the way your product addresses it), your product becomes the obvious solution.

The Feature-Ask Flow for Sales

A specific sales methodology for SaaS demos that dramatically improved close rates for the case studies presented:

  1. Identify the customer’s top pain points before the demo
  2. Show only the features that address those specific pain points
  3. After each feature, ask three questions:
    • Does what I just showed you solve the problem you have?
    • What do you think the impact on your business would be if you implemented this?
    • Is this something that you can see you and your team using?

“Every sale happens in the space between the pain and the promise.”

Customer Happiness Index (C.H.I.)

The proactive retention metric: a single score, derived from behavioral data (login frequency, feature usage) and outcome data, that predicts churn before customers know they’re going to leave.

“You can create one metric to figure out exactly how happy your customers are.”

The Win/Ask Method

The systematic process for generating referrals and social proof:

“The best time to ask someone for help is right after they win.”

Identify the moments in the customer journey where customers achieve significant wins (revenue milestones, activation achievements, case study-worthy outcomes), and build a systematic process for asking for reviews, testimonials, referrals, and case studies immediately after those wins occur.

Book Summary

Software as a Science (2024)

A playbook for scaling SaaS companies built around the Acquisition/Retention/Expansion framework. More practically operational than most SaaS books — it provides specific formulas, frameworks, and case studies rather than principles. Particularly valuable for B2B SaaS companies in the 10M ARR range who are hitting their first Growth Ceiling.

Key contributions:

  • The four-variable Growth Ceiling calculation
  • The sequencing principle (retention before acquisition)
  • The channel maturity scorecard
  • The Feature-Ask Flow for sales
  • The Customer Happiness Index for proactive retention
  • The Win/Ask method for referrals and social proof
