“I started building this in August 2024 when I discovered Cursor... Within 15 minutes, I got it to $100,000 of ARR and within two weeks, I got it to $300,000 of ARR. We have almost 500 active paid subscribers”
Editor's note: The founder had a large X audience before launch (his thread on the open-sourced X algorithm went viral and brought him hundreds of thousands of followers), and he credits that audience for the launch-day sales. He started building in Cursor in August 2024 and later moved to Windsurf; he uses ChatGPT o3 as his 'product manager'. The interview was published in June 2025, so the figure is from then.
How they got customers
His own X audience. He shared the build for six or seven months, ran a beta with about 150 testers from his followers (meeting each one), announced the launch date 12 days ahead and spent launch day talking about it on X Spaces.
Steps to try
