With Ben Cera, Founder of Polsia
Polsia had about $1.5 million in annualized revenue when its founder first came on the podcast. Ben Cera, founder of Polsia, told Julian on Solo Founders, about seven months later, that the company has passed a $20 million run rate and raised $30 million at a $250 million valuation, with no co-founders.
Startup investors have long expected a technical co-founder beside a business founder. Ben's last company had two co-founders, added largely for the pitch deck, and he now writes software by prompting AI tools himself.
"I was like, okay, I could hire an engineer, but then I would have to explain to that engineer what to build and then they would prompt Claude Code to build it, versus me directly prompting Claude to do it." — Ben Cera
Polsia is Ben's sixth company, an AI product that builds and runs online businesses for nearly 50,000 paying customers, and he remains its only full-time employee.

Here are the 9 lessons that matter.
Key Takeaways
Polsia grew from about $1.5M to more than $20M in annualized revenue in roughly 7 months, with one founder
Ben says AI has replaced the reason to have a technical co-founder
Customers complained about bugs, never about the name, which is "AI slop" spelled backwards
Every setup step loses customers, so Polsia's job is to remove them
Stripe, a bank account, an address: "just like those two or three steps, you just lose people"
Ben thinks only about 2% of Americans pay for AI, so the market is early
Ben compares taking a co-founder to getting engaged, and advises trying to build alone first
1. $1.5M to $20M in 7 Months
Ben spent a year building four or five software-as-a-service products before Polsia. Building had become so easy, he found, that taste decided which ones were any good.
Ben Cera says cheap software made judgment the scarce part of building
"I spent the year building four, five SaaSes, but very fast I realized it's so easy to build that there's so much subjectivity and taste you have to put in everything you do." — Ben Cera
In mid-2025 he settled on an idea he describes as a creative choice more than a researched one.
"What about I start this product which is an AI that can help you build and run companies autonomously, which sounded kind of crazy at the time." — Ben Cera
