When analyzing B2B SaaS opportunities, I like to think through things like nice-to-have vs must-have, market size, point on the lifecycle adoption curve, etc. There’s another area that I like to bucket SaaS apps: functional categories. Functional categories are a big, general way to think about what the app does and how it fits in with the user.
Here are the three main functional categories for B2B SaaS apps:
- Major Job Function — This is for apps where the app is one of the top three apps used daily by the person (e.g. SalesLoft and Gmail would be the main apps for an SDR).
- Specialized Job Function — This is for apps where the app is used at least weekly to accomplish a function but aren’t an app that the end user “lives” in daily (e.g. Calendly for automating meeting scheduling).
- Utility — This is for apps that are always running in the background acting as a utility for a specific function (e.g. Rigor for performance monitoring).
Look at the public SaaS companies and you’ll be able to easily categorize each one into one of the three main functional categories for SaaS apps. Also of note is that the largest SaaS companies by revenue are all major job function apps (there are plenty of successful specialized job function and utility apps as well, but they aren’t nearly as large as the major job function apps).
What else? What are some more thoughts on the three main functional SaaS app categories?
