How She Built a $100K AI App While Working Full-Time at IBM
TL;DR: Pauline spent years as a part-time indie hacker building side projects before finding success with AI Carea, an AI tool that shows what homes would look like with different interior styles. She built the MVP in one month with simple features and bad quality, then showed it to real estate agents found online and in her personal network. When people wanted to buy it immediately, she knew she had validation. She grew it to 8,000 users and $8,000/month revenue by marketing on Facebook and physical events where real estate agents gather. She reduced churn drastically by adding yearly plans, free trials, and continuously improving quality. After building the business while working nights and weekends at IBM, she quit her job two months ago to work full-time as an entrepreneur.
Key Insights
- Ship MVP in one month with simple features to validate demand quickly, then spend a year improving based on customer feedback
- Find customers by identifying where they gather online (Facebook groups for real estate agents, Twitter for developers)
- Reduce churn by offering yearly plans (locks in commitment), free trials (lets users validate fit), and continuously improving quality
- Offer both subscription and one-time payment to capture customers who hate subscriptions
- Build side projects while employed to validate ideas without financial pressure
Actionable Takeaways
- Ship your MVP in 30 days with basic features rather than waiting for perfection
- Search social platforms (LinkedIn, Facebook, Reddit) for where your target customers gather
- Ask potential customers frequency questions: 'How often do you have this problem?'
- Show your MVP to 5-10 target users and look for immediate willingness to pay
- Add a yearly plan option to reduce churn and increase customer commitment
