I Turned This Spreadsheet Into a $30K/Month Micro-SaaS

Profit AI launched in December, has generated a total of $147,000 in revenue to date, and currently achieves $30,000 MRR for the app alone and just under $40,000 MRR including services.

Jack, with no prior coding experience, built the app over 3 to 4 months using AI (Cursor, later Claude Code). He developed it by simply downloading the spreadsheet as a CSV and instructing the AI to 'build this'.

There are currently 122 users, with 38 to 39 being paying customers. A free plan is offered, providing new registrants with a 30-day free trial of the paid plan. The monthly fee was initially $5,000 but has since been lowered to $800.

With 47 installs and 43 uninstalls, the churn rate is almost equal to customer acquisition. Most of the growth has been through word-of-mouth, as no extensive marketing campaigns have been launched yet.

In 2016, Jack launched an e-commerce brand for music producers, offering software and sample packs, and succeeded with a high-profit-margin business. Subsequently, as a consultant for e-commerce brands and agencies, he created spreadsheets to aid in decision-making.

The e-commerce tools and software sector presents significant opportunities. There's an example of an entrepreneur named Erikas, whose Shopify plugin grew from $200,000 a month a year ago to $1,000,000 a month currently.

The current tech stack includes Claude Code (approx. $200/month on the max plan), Framer (for the website), Instantly (for marketing), CodeX (within the terminal, effectively free with a 100% discount), and Google Sheets (free).

The biggest advice for transforming a spreadsheet into an app is 'don't aim for laziness'. If your goal is to make a lot of money doing nothing, you'll quickly be replaced by the market. It's important to ask Claude 'can it do this?' and to keep trying and sticking at it.

Good decision-making comes from information. Data should be provided in an easily accessible format, but since spreadsheets are tedious and time-consuming, there's significant room for automation.

Turning repetitive, boring tasks into simple products is a great source of SaaS ideas. While building apps was difficult a few years ago, now is the perfect time to transform spreadsheets into profitable apps.
