Rule of 40: SaaS growth quality matters more than growth alone
The Rule of 40 is one of the clearest ways to evaluate SaaS and software companies because it combines revenue growth and profitability into one efficiency metric. A company above 40% usually shows a better balance between expansion and financial discipline.
For this analysis, I use GAAP EBITDA Margin TTM + next-year revenue growth estimates. The metric helps compare companies across different stages, from mature platforms to faster-growing AI-driven software names.
$ADSK Autodesk — 41% Rule 40 Autodesk is shifting from legacy CAD into a broader cloud workflow platform. The key angle is AI-assisted design, construction, manufacturing, and maintenance data integration, supported by the planned MaintainX acquisition.

Adobe still controls critical creative and document workflows. Firefly and Acrobat AI Assistant give the company direct AI monetization channels, while subscription lock-in keeps the business highly defensible.
$FTNT Fortinet — 50% Rule 40
Fortinet blends cybersecurity software with proprietary hardware. Its ASIC-based architecture creates performance and power advantages, especially as data centers need specialized firewalls for AI infrastructure.
