AI business case studies: revenue and exits
These are case studies of businesses built on generative AI, image generation and LLMs, where the founder has publicly disclosed revenue or a sale price. Small Start records the monthly revenue, exit price and acquisition channels with sources.
AI numbers are easy to exaggerate. Everything here is a figure the founder published, with the source attached — including businesses that grew and were then shut down anyway.

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.
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.
Leadverse Gets All Its Customers From Reddit, and 90% of Its Costs Are LLM Fees — $3,300 MRR Built Between a Day Job and a Newborn
Leadverse, an AI tool that finds prospects on social media, reached $3,300 MRR and 130+ paying customers ten months after launch. Every dollar of revenue comes from Reddit, and LLM API fees make up about 90% of operating costs.
Faceless.video: $1M ARR in 10 Months — a Non-Engineer's Seventh Bubble App After Six Misses
A former music producer built six failed apps on no-code Bubble, then hit with the seventh: Faceless.video reached $1M ARR ten months after launch. Current MRR exceeds $83,000, with 2.5 million cumulative 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
Three AI tools run by a data scientist alongside his day job. Combined signups exceed 2.5 million, yet current monthly revenue is $6,500–7,000 — down from the 2025 peak of $100K a year.
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.
MDZ.AI: Bundling $200/Month of AI Tool Subscriptions Into a $49 Plan — $165K/Month in Two Years
Su Jimmy's AI tool for e-commerce sellers, "MDZ.AI," launched in January 2024. Bundling 15+ AI models into a $49/month plan, it hit 500 beta signups in 24 hours and 100 paying users in two weeks, now generating $165K/month (about ¥24.75M).
Business Name Generator Domainify Sells for Eight Figures: A Suite of Tools That Captured the "Naming Moment"

SEO Content SaaS Contentpace Sells to an AI Content Company at 2.5x Revenue
Contentpace, a SaaS for building and optimizing SEO article outlines, was sold to AI content generator Content at Scale for 2.5x revenue. Rather than fighting the generative AI flood as a standalone tool, the founder chose to become a feature inside an AI company.
36,500 subscribers, but two years of total revenue in the high hundreds-of-thousands of yen. An AI-explainer YouTube channel's hourly wage: ¥416
An AI-tool explainer channel grew to 36,500 subscribers two years after launching in April 2024. But two-year total revenue was only in the high hundreds of thousands of yen, recently a few tens of thousands of yen per month. Across 112 videos at an estimated 30 hours each, that works out to an hourly wage of ¥416. The turning point wasn't stagnation — it was the year-two conclusion that ad revenue had plateaued, reached after every stated goal had been met.
Boardroom Insiders: A Solo-Founded Executive Database Hits $5M ARR, Sells for $25M — Winning With “Human-Curated Data”
Boardroom Insiders, a profile database of large-company executives started by former marketer Sharon Gillenwater, grew to $5M ARR and was sold to UK information giant Euromoney for $25M (5x revenue). A textbook exit for "human-curated data" that AI can't replicate.
TalkNotes: Sold for $200,000 in 11 Months — Why the $7,000-MRR AI Voice-Memo App Chose an All-Cash Deal
Nico Jeannen sold his AI voice-memo app TalkNotes for $200,000 just 11 months after launch — turning down a higher $300,000 earnout offer for cash up front.

Easy Folders: One Chrome Extension, $3,700 MRR and $42,000 Lifetime Revenue in 6 Months — a “Fill the Gap” Structure
Edmund Yong's Chrome extension "Easy Folders" hit $3,700+ MRR and $42,000+ in lifetime revenue 6 months post-launch. Running costs are just his Mailgun bill. This piece breaks down a structure built on filling a $9/month gap: ChatGPT's missing folder feature.
AI Generation × Adobe Stock: ¥500,000 a Year. Twelve Months of Real Data Behind the ¥42,000/Month a Salaryman in His 40s Built on Weekends Alone
Rossin, a company employee in his 40s, sells Midjourney-generated images on Adobe Stock and published his 2025 earnings month by month: ¥501,834 for the year (¥41,819 monthly average). The peak was ¥56,000 in December — seasonal assets drive sales. Three years of continuous operation, working weekends only.
The Neuron: A College Sophomore’s AI Newsletter Hit 500,000 Subscribers and 7-Figure Revenue in 2 Years — Growth Design, Up to the Sale
The AI newsletter The Neuron was launched in 2023, right after ChatGPT went public, by a college sophomore and a recent graduate. It went from 10,000 subscribers in month one to 200,000 in year one to 500,000 in year two, with 7-figure annual revenue. Using organic posting, Meta ads, and acquisitions of smaller newsletters, it sold to TechnologyAdvice in January 2025 for cash plus an earnout.
Talknotes: 17 Built, 1 Hit — the Breakdown Behind an AI Voice-Notes App at $9,000/Month and 900 Paying Users

The turning point was abandoning SEO and building a loop that recycled annual prepayments straight into ad spend.
Klipy: COVID Debt, Six Wasted Years — How a 3-Person AI CRM Reached 5-Figure MRR and 4,000 Companies
Jung Hong Kim, who had sold two machine-vision companies, lost his third to COVID and was left in debt. During roughly six years as a consultant, he noticed a mismatch between how people think and how data gets stored — and from that insight built the AI CRM Klipy, coding the MVP himself in three months and reaching 4,000 companies and 5-figure MRR in about a year and eight months.
Jenni AI: From $2K MRR to $6M ARR on 12,000 TikToks a Month — Examining the “Creator Factory” Marketing
AI writing-assistant Jenni AI went from a stalled $2K MRR to $6M ARR and 3 million users by systematically mass-producing short-form videos on TikTok/Reels. At its peak, 200+ creators were posting 12,000 videos a month — a textbook case of modern "industrialized virality."
InteriorAI: An AI That Redesigns a Room From a Photo, at $40K a Month — The First Mass-Produced "AI × Existing Industry" Product
InteriorAI, which generates interior-design concepts from a photo of a room, earns $40K a month (about ¥6M). Like PhotoAI, it's one of the products Pieter Levels mass-produced early in the 2022 AI-image-generation boom — a case of "AI substituting for an existing high-cost service."
AppAlchemy: A Mobile App Builder Built in 2 Weeks Hit $10,000+ MRR in a Year — Finding an Open Seat
Diego Roshardt built an MVP in two weeks and started charging from day one. About a year after launch, he passed $10,000 MRR. The turning point was positioning — spotting that mobile was an empty seat while web-based AI app builders were booming — plus a single night of traffic from a major X account.
Leadmore AI reaches $30K/month. Talked to 50-100 people before building, and says the MVP should have shipped with one feature instead of three
