What It Actually Cost to Build a SaaS in 2026: $35,020, Five Months, One Person

I spent five months and a little over $35,000 building a fully featured software company by myself. I can tell you every line of code, every dollar, and every mistake.

What I cannot tell you is whether it becomes a profitable business. Those are two different things, and most building-in-public content pretends they are the same thing. This is the first half of the story - the half I can prove.

The idea arrived on February 13. Twenty-four days later JobIntel went live. Five months on, the codebase is about 566,000 lines - and there is more test code than application code, roughly 1.26 lines of test for every line of app. That ratio is not an accident. It is the only reason one person can operate this.

The money, in six categories: AI agents $11,597, AWS hosting $4,545, marketing and media $4,765, domains $3,895, hardware $3,723, everything else $6,495. Total $35,020. The napkin math against the old way - five engineers for five months at a loaded $12,500 a month - is about $312,500. Call it a 9x difference.

The failures section is longer than the wins, deliberately. A CI misconfiguration that nearly locked in a $59,500-a-year AI bill. A fully green pipeline that coexisted with a bug giving users 0% match scores. A bug that quietly destroyed user data for three days while the logs reported success. An entire enterprise module built and then deleted. A review robot that filed 133 bad tickets before I switched it off.

And the part that matters most: none of it is product-market fit. If building is now roughly ten times cheaper, the technical implementation is no longer the moat, or the proof, or the finish line. It is the entry fee.
