Indie Hacker Sells AI SaaS for Five Figures
Founder Yifan Goh detailed the full lifecycle of building, validating, and selling OurBabyAI for a five-figure sum. The project, which used Midjourney to generate baby images, demonstrates a viable "micro-exit" strategy: build a niche AI tool fast, validate it with real users, and sell it early after establishing product-market fit.
The founder, Yifan Goh, started OurBabyAI on April 1, 2023, with a simple idea to use Midjourney to see what his future child might look like. He validated the concept by creating a landing page in one day and, after some initial hesitation, launched it by submitting the site to various AI tool directories to gain visibility and backlinks. The first sale came on April 11, 2023, which proved people were willing to pay for the service. Initially, Goh fulfilled orders manually by generating the images in Midjourney himself and emailing them to customers. As sales grew, reaching a peak of $2,900 in monthly revenue by July 2023, he built a Node.js backend to automate the image generation and email delivery, effectively creating a passive income stream. The business operated with high profit margins of around 90%, with its main costs being fixed expenses like hosting. The five-figure exit in June 2024 happened after Goh listed the project on Acquire.com without success. The eventual buyer was a follower on Twitter who lived nearby in Singapore, and they finalized the deal after a few coffee meetings by drafting their own Asset Purchase Agreement. This type of sale is often referred to as a "micro-exit," a strategy where founders of small, profitable, niche SaaS businesses sell to individual buyers or small funds. The technical implementation of OurBabyAI relied on Midjourney for image generation. While Midjourney does not offer an official public API, developers can access its capabilities through unofficial APIs or by building their own automation using Discord bots. These unofficial solutions often involve reverse-engineering the web version of Discord or creating bots to listen for and respond to messages from the Midjourney bot. This "build and sell" strategy is becoming increasingly common among indie hackers leveraging the power of AI. Founders identify a niche problem, use existing AI models like those from OpenAI or image generators, and quickly build a "wrapper" or a specialized tool around them. The focus is on rapid validation, achieving profitability, and then selling the business as a turnkey asset, sometimes in a matter of weeks. For frontend engineers, the rise of AI coding assistants like GitHub Copilot and more advanced agents like Devin is fundamentally changing development workflows. These tools handle boilerplate code, assist in debugging, and even take on complex implementation tasks, allowing engineers to focus more on architecture, user experience, and product strategy. This shift empowers solo founders and small teams to build and ship more complex applications faster than ever before.
