The Next Wave of SaaS is Vertical

TLDR: The value in software has moved from the application to the workflow, and workflows are vertical. The companies that win in the next decade won’t be the ones with the broadest horizontal tools. They’ll be the vertical platforms that own one industry’s system of record and monetize everything that moves through it.

Why is the next wave of SaaS vertical rather than horizontal?

Because the scarce thing is no longer software itself; it’s software that understands a specific industry deeply enough to run it. Horizontal tools win on breadth: one CRM, one spreadsheet, one project tracker for everyone. Vertical software wins on depth, and depth is where durable advantage now lives.

In the last era before the advent of AI, when software was scarce, owning a horizontal category meant owning a market. But software isn’t scarce anymore. What’s scarce is software that knows how a wholesale business takes orders, how a manufacturer’s representatives are paid, and the compliance requirements a clinic must meet.

A vertical company sits at the system of record for its industry: the place where the real work and the real data flow through. From that position, you can do things a horizontal tool structurally can’t: embed the payments, the credit, the insurance, the logistics that the industry runs on.

The software is the wedge. The industry’s operations are the prize.

What changed? Why is this vertical SaaS' breakout moment?

Three things converged, and they didn’t used to be true at the same time:

1. The infrastructure finally exists: A decade ago, if a vertical software company wanted to add payments or lending, it had to become a payments or lending company and provide licenses, underwriting, compliance, the whole apparatus. Today that capability is available as infrastructure you build on. The barrier that kept vertical companies stuck selling seats came down.

2. AI changed the economics of deep software: The cost of building features collapsed. That sounds like AI has commoditized software, but for vertical players it does the opposite. It frees them to do the hard, defensible work: deepening the workflow, automating operations and monetizing transactions. The generic gets cheap; the specialized gets more valuable.

3. The market learned what to reward. Operators and investors can now see plainly that revenue tied to a customer’s transaction volume is worth more than revenue tied to their headcount; it’s stickier, it compounds, and it grows on its own. That recognition has pulled capital and talent toward the model vertical SaaS is built for.
   

Vertical software was always a good idea. This is the first moment all the pieces are in place to realize it.

What should founders do about it?

If you’re choosing a path: go deep. Pick an industry you can understand better than anyone else and become the platform it runs on. Owning an industry’s system of record and the commerce that flows through it is more defensible, and ultimately larger, than being one more general-purpose tool.

If you’re already vertical: you’re sitting on the most valuable position in software. The only question is how fast you turn it into more than a subscription business. You’ve made the right bet. Now press it.
