been ghostwriting on linkedin for 5 years (managed to generate 100M+ views for clients) but the process was killing me. spending hours interviewing clients, understanding their voice, crafting authentic content.
After failing at 3 other SaaS products – all built in isolation with zero customer input – he decided to build something for a problem he actually had.
gave myself a deadline: ship in 42 days. instead of assuming what people wanted, asked them. then built exactly what they asked for, often shipping features in 24 hours after feedback.
The result is Oiti, an AI ghostwriting tool for LinkedIn. His first customer was an agency managing 30+ LinkedIn posts per week.
~$600/month after about 4 months.
not life-changing money yet, but it’s growing and people actually use it daily.
He taught himself to code at 30. Three failed products before this one. The difference? This time he built a tool around work he’d been doing for years.
What repetitive work do you already do that could be made faster with a simple app? 
With vibe-coding tools available now, you don’t need to spend months learning to code. You could prototype something in a weekend.
If it makes your own work easier, chances are other people doing the same work would pay for it too
