Joe Lonsdale: low-end SaaS without moats is in trouble, but AI-forward incumbents with strong tech cultures will thrive

Low-end SaaS faces real pressure in the next few years. This category consists of undifferentiated, sales-heavy software that private equity firms have traditionally bought and flipped. These companies required relatively little engineering investment and relied on outspending competitors on sales to gain ground.

The dividing line is sharp. Incumbent SaaS players with hundreds of millions or billions in cumulative R&D, strong engineering cultures, and active AI roadmaps are positioned to thrive. One of Lonsdale's portfolio companies, a CEO who dominates a niche in financial services, illustrates the pattern concretely. That company has rolled out AI agents and is already adding tens of millions in incremental revenue.

AI is becoming a defensibility feature, not a feature set. Companies that can actually build and integrate agents have a moat. Those that relied instead on sales distribution and shallow product do not.

“I think low-end SaaS is in trouble the next few years. It's probably the stuff that Constellation Software used to do — things with PE bought, didn't take that much to build, probably put more money into sales than tech. That stuff's in trouble. But if you have a great SaaS company that spent hundreds of millions or billions of dollars and you still have a great tech culture and you're using AI, you're fine. One of our CEOs dominates a big part of the financial industry in one particular niche and now he's rolled out agents and is adding tens of millions in revenue.”
