SEObot: An AI That Writes SEO Articles Hits $46K MRR and $1.8M Lifetime — the Numbers Come from a Public Stripe-Linked Dashboard
John Rush's SEObot is a SaaS where AI keeps writing SEO articles. As of August 2026, its $46,517 MRR, $1.82M lifetime revenue, and 636 subscriptions are verifiable by anyone on a Stripe-connected public dashboard. Reading the numbers, AI-content controversy and all.
GummySearch: The Reddit Research SaaS That Chose to Close While Profitable — Four Years Ended by a Commercial API License That Never Came
After roughly four years running his Reddit research tool alone, founder Fed shut GummySearch down in November 2025 when commercial-license negotiations over the Data API fell through. Failory reported $35K MRR at closure. With 140,000 users and the business in the black, this was an ending caused by neither churn nor running out of money.
The God of Blog: 310K Pageviews Made ¥47K a Month, 6,499 Pageviews Made ¥53K — a 6-Year-2-Month Measured Record of Niche Selection
A One Piece analysis blog earned ¥46,801 on 310K monthly pageviews; the third blog, about blogging itself, earns ¥53,232 on 6,499. Per-pageview value of ¥0.15 versus ¥8.2 — Hebo published the full 6 years 2 months it took to reach ¥50K a month, failed sites' numbers included.
BoltAI: $15K a Month on One-Time Licenses in a Subscription-Only AI Market
Vietnamese solo developer Daniel Nguyen went against the "AI tools = subscriptions" consensus and sells BoltAI, a native macOS AI app, as a one-time license: an average of $15K a month and 7,000 customers 18 months after launch. He also documented the $19→$79 price climb and the year lost on his failed first product, KTool.

ProjectionLab started at $150 MRR in 2021 and reached $1M ARR in June 2025. Developer Kyle Nolan quit his job only at $23K MRR. A Hacker News post, one word from Mr. Money Mustache, and an 8,500-member Discord were the main engines of growth.
Inkdrop: ¥150,000 a Month from a $4.99 Markdown Note App — Two Years of an Indie SaaS That Stopped PR Emails and Refused to Go Freemium
Japanese developer TAKUYA's Inkdrop reached ¥150,000 in monthly sales about two years after launch, with a ¥950,000 single-month spike in August 2019. A 1,000-person private beta, a 60-day free trial, no freemium, no more PR emails — the reasoning behind each decision is public, alongside the numbers.
Skeb: The "Personal Hobby Service" That Sold All Its Shares for ¥1 Billion — Settling the Risk of One Person Holding ¥200 Million a Month in Transactions
Skeb, which its founder called a "personal hobby service," reached 1 million registered users and roughly ¥200 million in monthly transaction volume in just over two years, then became a subsidiary of Jitsugyo no Nihon Sha in February 2021 for ¥1 billion.

Youform found its first 200 users by searching X and Reddit for people complaining about Typeform's price hike and DMing them individually. A 40-day lifetime deal raised $35,000 up front; about two years in, MRR is $18,000 with 80,000 signups.
AI Directories: $10,000 a Month from One-Time Purchases, Built on a Chore He Automated
A service that submits AI products to 100+ directories by hand. Built for the founder's own use, it became the biggest earner in his portfolio, now at $10,000/month across products. But the three numbers he publishes — interview, pricing page, revenue page — don't match.
Base44: Six Months Old, Eight Employees, an $80M All-Cash Sale — but $25M of It Was Retention Pay
Base44, the AI app-building platform started by one person, sold to Wix for $80M in cash about six months after founding. But $25M of that is retention compensation for its eight employees — the headline number cannot be read as the founder's take.
Questgen & Supermeme Today: 2.5 Million Signups, $6,500–7,000 a Month — Three AI Tools Down From a $100K Peak Year

Katsuhito Saiki, who worked at a seafood trading company, took over "Abbey Road," a watchband shop that had run for 20+ years on Rakuten Market.

Negotiations spanned about 1 year and 8 months.
Is a coin laundry passive income? ¥150,000-500,000 a month, 7-10 year payback — an owner's numbers
A current owner running a coin laundry as a side business published their income statement: initial investment of ¥13-22 million, monthly revenue of ¥150,000-500,000, fixed costs of ¥250,000-530,000, take-home of a few tens of thousands to over ¥100,000 per month, with a 7-10 year payback period. We examine content in which the operator personally dismantles the "passive income" image.

22 Udemy Courses, 8 Bestsellers, $2,124 a Month on Average: Building a "Shelf of Courses" on a Global Platform

The Daily Lodging Report, a daily newsletter covering the hotel and lodging industry, was run by Alan Woinski and his wife, who sold annual subscriptions at $450 to thousands of readers before selling the business to travel-industry media company Skift in 2021.

Damon Chen: Bought a GitHub Repo for $20K, Grew It to $1.5M ARR — the “Buy, Don’t Build” Indie Playbook
Former engineer Damon Chen grew Testimonial.to to over $2M cumulative revenue in four years, then in the early ChatGPT boom bought a pre-revenue repository (now PDF.ai) for $20K. Repositioned as "AI you can chat with about PDFs," it grew to $1.5M ARR within months. A defining example of indie development that buys the seed instead of building from scratch.

Puzzle Ready, a puzzle-table e-commerce brand, kept 99% of sales on Amazon FBA and still reached $3M/year, selling to eBrands in December 2021 at 6x profit (3.5x upfront + 2.5x earnout). The turning point was a design choice: pick an aggregator as the target buyer and refuse to diversify.
A high schooler's paid Discord bot nets ¥12,000/month profit — reading the logic behind pricing ¥500 on top of a ¥320 cost
Entering a Discord text-to-speech market full of free bots at ¥500/month, cost about ¥320 per 200,000 characters, and ¥12,000/month profit by year two. Even the signup pace is quantified.

The Revenue Record of 9 Udemy Courses — the First Took 100 Hours and Made $165, and What It Taught Produced a "¥1.5 Million Course"
Udemy bestselling instructor Naoto Takizawa published real data across 9 courses. His first course took about 100 hours and earned $165 (about ¥20,000) in a year, but a later course refined through iteration cleared $10,000 (¥1.5 million) in profit. Monthly students grew from 34 in the first month to 563 within a year. The explanation of the mechanics — including revenue shares (97% for self-referred sales / 37% for Udemy-sourced) — is invaluable.

Over three-plus years of persistence, MAU grew more than 100x and revenue reached ¥100,000 a month from AdMob ads alone. A record of the growth curve of an app with no paid features and no marketing — one that simply stayed on the store.
Four Rental Spaces Generating ¥360,000 in Monthly Profit. 30% Fees, ¥450,000–700,000 Upfront — the Going Rates of the Hourly-Rental Market
Serial entrepreneur Kenji Sato published both his track record — four rental spaces producing ¥360,000 in monthly profit — and a market-wide picture of the going rates. Hourly rates cluster at ¥3,000–6,000, platform fees run 30–35%, upfront costs are ¥450,000–700,000, and roughly 30% of operators lose money in year one.

A regional residential street (20 min walk from the station) saw 32 days of use in a year — ¥741/month average, ¥2,164 best month. The urban case filled 3–4 days a week for about ¥4,500/month.

Justin Welsh, a former healthcare-SaaS sales executive, went independent in 2019 and built a one-person business portfolio of social-media content, digital courses, and a newsletter, generating over $2M a year and over $12.5M cumulative (self-disclosed).

A 50-something engineer at a manufacturer published 8 apps for iOS and 2 for Android. Steady ASO work drove growth until 2021, when he peaked at nearly 50,000 yen a month. After he stopped building new apps in 2022, revenue declined, and it now sits around 30,000 yen a month.

From ¥2,000 to ¥20,000 a video: three years of video editing, and the turning point of "direct sales after the director quit"
An individual on leave from an engineering job moved into video editing with no prior experience. The first gig paid ¥5,000 a video; the cheapest paid ¥2,000 for six hours of work. Of eight clients, all but one fell through — until in June 2023 he pitched the one surviving client directly and converted it into a direct contract. The rate rose from ¥10,000 to ¥14,000 to ¥20,000. He now earns ¥200,000–300,000/month from that single client.

A restaurant company running a dozen-plus outlets divested a Tokyo grilled-fish specialty restaurant as part of "selection and concentration"; an experienced individual took it over in January 2024.
