“Bro vibe coded a $20k MRR app in 14 days.”

“Left my job. Left my home. Living on savings. […] Goal: Build a $10k/month SaaS and document the process.”

“SaaS” is software paid for by subscription. “Vibe coding” means having an AI tool write the code. MRR, monthly recurring revenue, is the price times the number paying this month, before fees, costs and tax. We checked what became of the second tweet’s goal against payment records; see The upside. This page judges the scheme, not the people who tweeted.

The sums

The most common monthly price across more than 115,000 subscription apps is $10⁶. At that price, $10,000 a month needs 1,071 paying subscribers on the web or 1,177 in an app store, after payment or app-store fees (our sums)²⁴.

If 2% of downloads end up paying (our estimate), 1,177 payers needs about 59,000 downloads⁶. On monthly app plans, 6% to 14% of subscribers still pay after a year, so an MRR figure describes one month⁶.

Buying those downloads with ads loses money at median (middle) numbers. A US subscriber costs about $67 to $130 on Apple’s ad system (our sums); the median payer on Apple’s store worldwide brings in about $23 (different samples, so rough)⁶¹⁴.

What happens to most people who try

Among newly launched subscription apps, 17.3% reach $1,000 in monthly revenue within two years and 4.6% reach $10,000: about 1 in 6 and about 1 in 22⁶. The median app earns about $72 a month a year after launch⁶. These count apps, not people, and include companies’ apps⁶.

Web figures come from TrustMRR, a public list that reads money received, not profit, from the founder’s payment account¹⁶. Two outside analyses of it put the median at $169 and $145 a month. One is by a forum user, the other by a company that sells a database of software ideas; we recomputed neither¹⁰¹¹. No sample counts people who never finished or never charged.

Our estimate: a capable newcomer’s first product most likely earns between nothing and about $100 a month after a year.

The upside

One year after launch, the top quarter of subscription apps earns above $429 a month and the top tenth above $2,574⁶. Among listed web products of every age with revenue, that company’s analysis puts the top quarter above $894 a month, the top tenth above $5,107, and says 23.6% reach $1,000 a month¹¹.

Two payment-verified outcomes:

• SuperX, @robj3d3’s tool for growing an audience on X: $21,866 MRR about 21 months after he started¹⁹. He had about 65,000 followers in October 2026¹.
• Conductor, which connects other software to an accounting program: $41,447 MRR from 264 subscriptions after about four years. Its founder has 1,032 followers⁶¹. We do not know whether one person runs it.

These are rare. About 50 of the more than 15,000 listings TrustMRR says it has show $41,000 a month or more: about 1 in 300 (our sum)¹⁶.

Our estimate of a good result about a year in, for a product that charges: roughly $430 to $900 a month. A very good one: roughly $2,500 to $5,000⁶¹¹.

What it takes to compete

Stripe, using data from a service it sells, compared the top tenth of solo founders with the middle. All had paid to set up a US company, so they are a committed group⁵⁸. The top tenth:

• More often sell to businesses. They were nearly 30% more likely to. By month 24 the median solo founder selling to businesses had more than four times the revenue of one selling to consumers⁵⁸. Mobile apps point the other way: 1.6% of business apps reached $10,000 a month, against 8.9% of gaming apps⁶.
• Keep their customers. Nearly 30% of first-month customers came back the next month, against 8% in the middle⁵⁸.

The rest of the record adds:

• Time. First-year projects had a median of $148 a month; five-year-old survivors $2,509¹⁰.
• A price that fits the buyer. The verified web products take in about $14 to $157 per subscription a month (our sums) and hold 264 to 3,019 subscriptions. Conductor takes in the most per subscription and holds the fewest^1920606162.
• Several attempts. One winner reports nine failures in ten, another 4 that grew out of more than 70¹⁸⁶⁸.

Tools cost about $800 to $2,300 a year (our estimate)¹⁵. The larger cost is time: about 21 months to nearly six years in the verified cases¹⁹⁶².

Early tests: strangers pay soon after launch, and first-month customers pay again. The commonest reported failure is sign-ups without payments²⁶.

Who else makes money from it

Of our 52 tweets, 31 lead to something (our labels): the author’s own app, a paid list, a service, a tool, or a link sent on request¹.

Starter Story, which posted the first tweet, sells builders a $395 programme; we found no outcome figures for buyers²¹. Marc Lou runs TrustMRR¹⁶⁹. Of the $3,212,777 of verified revenue on his own page, about two thirds (our sum) came from a starter code kit and a coding course sold to would-be builders¹⁷.
