AdTech Is Now the Top US SaaS Vertical

Something fascinating is happening in SaaS.

For more than 20 years, Software was the dominant sub category among SaaS companies. Now it has fallen to second place.

AdTech Is Now the Top SaaS Vertical in the US

In the US, the new leader is AdTech.

And that may tell us something about where the US sees the next opportunity.

AI tools such as Claude can dramatically reduce the time, engineering effort and capital required to turn an idea into working software.

Now you have to sell it.

Distribution, customer acquisition, targeting, attribution and advertising become even more valuable. The US SaaS market appears to be moving in that direction, with more companies helping businesses compete for attention and customers.

Education Leads SaaS Outside the US

Outside the US, the picture looks very different.

Education is moving to the top.

AI can explain algebra, teach languages, tutor students, personalize lessons and make high quality instruction available at a fraction of the historical cost.

For developing countries, that could change the economics of education.

Higher education levels can mean stronger economies, more skilled workers and a much larger pool of engineers, scientists, founders and researchers entering the global economy.

Selling vs Learning: Two Different SaaS Bets

So there is an interesting contrast emerging.

The US appears to be investing heavily in selling more effectively.

Much of the rest of the world appears to be investing in learning more effectively.

Which turns out to be the smarter move?

Healthcare SaaS Is Rising in Both Markets

Healthcare is also rising in both tables.

Healthcare has enormous administrative complexity, expensive skilled labor and constant pressure to improve access while lowering costs, making it one of the clearest areas where AI enabled SaaS can create value.
