In this short monologue, Jason M. Lemkin explains how recent advances in AI have ignited a massive wave of new B2B SaaS products, making traditional SaaS appear to be fading. The surge has dramatically raised competition and quality expectations, as vendors must now match the performance of leading models like Claude and ChatGPT; subpar agents can no longer succeed. Lemkin highlights how AI agents have expanded previously niche markets—citing CX support tools and legal assistants such as Harvey—by ten to a hundred times, creating larger addressable markets and intensifying competition. He concludes by forecasting an imminent battle over a single, unified agent interface: despite the explosion of specialized apps, customers will gravitate toward one cohesive interface, shaping the next competitive frontier.

Chapters

Everything got so much more competitive the last year because AI just created a thousand flowers. As I said in the beginning, old SaaS may be dying, but new SaaS, new B2B is exploding like never before. And you can feel it in the competition. And but it's not that simple. The competition is so much better than everyone was. Not only are the vendors better, but everyone knows what's great now. Claude and ChatGPT are so great. You can't get away with crappy agents and crappy software. We all know And this— the fact that we can replace humans or make humans more, much more effective means that even niche markets are much larger. And the one example I'll give, and then I'll give two more and then I will wrap— it's the craziest one are some of these CX support products. And I've done a lot of investments, worked a lot, but these Sierra Decagon and also legal, Harvey Lawred, these were niche markets before agents. These were niche markets that are like 10 to 100 times larger because the agents add so much value. So that also means in a lot of markets there's a lot more competition because you can monetize them much better than you could with agents. And then maybe two last things to think about and then we will wrap. I copied this from— or a version of this from Owen from Intercom the other day. But another thing over the next couple of months is when we use 21 agents at Saastr, but everyone really— your customers just want to use one. They want to use one interface, maybe not one agent, but one interface. And there's a big battle that's coming. Even though the number of apps is exploding, when customers come to you, they want to use one agent, one interface. And this is rebooting.
