In SaaS entrepreneurship, it’s easy to believe that success requires venture capital, rapid scaling, and billion-dollar valuations. However, Joe Kowalski offers a compelling counter-narrative, one built on discipline, clarity of vision, and long-term commitment.
In this episode of SaaS That App, Joe shared with hosts Aaron Marchbanks and Justin Edwards his incredible journey from grinding aluminum parts for the minimum wage to building and selling a SaaS company with 35% market penetration, all without VC funding, and why he believes the future of software lies in smaller, tightly focused ventures: micro-SaaS.
Along the way, he unpacked hard-earned lessons in vertical market selection, pricing, AI adoption, and why a $3–5M ARR business can be just as exciting and profitable as a unicorn.
From the Lab to Launch
Joe’s path into SaaS wasn’t paved with investor decks or Ivy League degrees. At 23, he had no college education, a baby on the way, and a job polishing metal. Driven by curiosity, he worked his way into a chemistry lab and then discovered coding while optimizing lab processes.
Programming became a passion, and after recovering from cancer, Joe made a bold move: he left his job and launched one of the first SaaS companies for small businesses before SaaS even had a name.
His first product: A CRM platform for carpet cleaners, priced at $50/month, running over dial-up.
Two Mistakes That Cost Him a Billion-Dollar Exit
Despite building a solid product and eventually exiting for eight figures, Joe’s early decision came with tough lessons.
Mistake #1: Choosing the wrong vertical
Joe focused on carpet cleaners, a segment with a low average invoice value (around $250) and limited room for pricing elasticity. Meanwhile, competitors like ServiceTitan went after HVAC with $7500 invoices and charged $1200/month. The result? ServiceTitan became a $4B company. Joe’s? “I sold for a lot, but it could’ve been way more.”
Mistake #2: Bad pricing decisions
He priced his services slightly above cost and continued to honor the original rates for his early customers for many years. Some were still on 2003 pricing when he sold. Joe’s reluctance to raise prices stemmed from fear of churn. But when he finally did, the churn barely moved.
Joe’s Secret
Joe’s company eventually thrived not through flashy growth hacks but deep attention to retention and user behavior. He scrutinized onboarding flows, post-90-day engagement, and what made customers stick. He found that repeat business was the key to customer lifetime value and that mailing physical reminder cards was the killer feature. Automating the process with in-house printers and part-time college workers allowed Joe to double monthly sales and generate a third of total revenue through direct mail marketing.
AI and the Rise of the Micro-SaaS Movement
Today, Joe sees a new wave of opportunity, especially for technical founders. With AI tools and infrastructure-as-a-service platforms, the barrier to entry is lower than ever.
“If you know what you’re doing, you can be a 100x engineer with AI,” Joe explained. He’s bullish on small, highly targeted SaaS products solving niche problems, what he calls micro-SaaS.
The formula?
- 2500 customers
- $100/month pricing
- 1.5% churn or better
- 70% margins
- = approximately $3M ARR and a $15–20M exit at a 5–7x multiple
However, Joe cautions about the hype: non-technical founders using AI to build MVPs without understanding what’s under the hood are often setting themselves up for failure.
Investing in Founders, Not Just Ideas
Now operating as an investor and advisor through SaaS Labs, Joe is focused on supporting the next generation of founders. But his criteria are exacting. An MVP with early traction is a minimum requirement. The idea alone is not enough. Nor is pure technical talent. He also advises founders to be highly selective about who they accept investment from. A misaligned investor can create years of tension, distraction, and misdirection.
The Long Game Requires Sacrifice
Joe spoke openly about the personal cost of bootstrapping a SaaS company over two decades. While he prioritized family, he made significant sacrifices in other areas, including leisure and personal income. In his view, sustainable success requires both deep commitment and thoughtful prioritization over the long term.
Final Thoughts
After stepping away from active operations and focusing on personal health, including multiple cancer recoveries and ongoing heart treatment, Joe is re-engaging. He plans to raise a small investment fund and resume working with founders, building the next wave of micro-SaaS products.
He’s also exploring opportunities in decentralized protocols such as AT Protocol (ATP), which powers social platforms like Bluesky. As Joe sees it, the same long view that served him well in the early days of SaaS will be essential as new data ownership models and infrastructure emerge.
