Convert Case is a free online text manipulator that assists you with tasks like converting letter cases, among others. A super boring business for a solo founder.
Convert Case was started in 2006 as a small, fun side-project by Jason Gillyon and has remained a solo endeavor since its launch.
Convert Case currently relies on two primary revenue streams: Google AdSense and donations.
The majority of the revenue is generated through Google AdSense, which benefits from an estimated 3.6 million monthly visits.
Donations contributes only a small portion to the overall revenue.
