The $2M ARR one-person SaaS — Jason Zigelbaum @ Zigpoll

A year ago, Jason Zigelbaum was running a SaaS business at roughly $1M ARR completely alone. A year later, he's approaching $2M — and he's still alone. So, how? Jason is one of the clearest real-world examples of what running an extremely lean SaaS with AI actually looks like. He uses AI to build product, analyze customer behavior, understand churn, identify his ICP, create marketing campaigns, build landing pages, analyze ad performance, and automate much of the work that would traditionally require a team. But this isn't a story about handing your company over to a bunch of autonomous agents. Jason is still very much in the driver's seat. We talk about how he structures AI workflows, why domain expertise makes AI dramatically more useful, and why the best tasks to delegate are often the ones you already know how to do — but simply don't have enough time to do yourself. We also get into one of the biggest questions facing SaaS founders right now: if anyone can build your product in a weekend, what makes your company defensible? For Jason, the answer is depth. Knowing your customer incredibly well, listening to their weirdly specific problems, and building solutions that someone starting from a blank prompt would never know to ask for. Then there's marketing. Jason explains how he's using AI to go from “nothing to good” rather than pretending it can automatically create world-class content, how he feeds his own customer and performance data back into the system, and why authentic founder content still tends to outperform perfectly automated posts. We also talk about the part of bootstrapping that doesn't get nearly as much attention: what do you actually do with the money once the business starts generating it? Jason has spent — and lost — plenty of money trying Google Ads, social ads, influencers, YouTube and other acquisition channels. Now he's using AI to create and optimize dozens of campaigns and landing pages while trying to solve the same problem every SaaS founder eventually faces: figuring out where another dollar of investment will actually produce more than a dollar in return. And despite automating almost everything, there's one thing Jason still refuses to hand over to AI: customer support. Because when you're the person answering every frustrated email, your customers are effectively writing your roadmap for you. Finally, we talk about the strange side effect of all this new leverage. AI was supposed to give us our time back. Instead, Jason is working harder, doing more, and moving the goalposts again. The next target? $4M ARR. Still solo.
