Jason Gillyon
- Founder of Convert Case
- $25,000 monthly revenue
Jason Gillyon is the founder of Convert Case, “a website that provides a simple and user-friendly tool for converting text between different letter case formats.”
💬 In a recent interview, he reveals…
The site earns well over 5 figures every month and my latest hosting bill is still only around $20 [per month].
Update: Right after publishing this story, Jason told us via email that the site has averaged $25,000 per month in revenue over the past 12 months.
🚀 It all started back in 2006, when…
A freelancer sent me an email in ALL CAPS and I needed it in the normal case, so I built a prototype in around an hour rather than retyping it all.
Jason has added more tools to the site over the years, so it’s no longer just a case formatting site.
For example 👇
Jason writes…
I try to add a new tool around once a month and continue to invest in SEO and content optimisation. The site continues to grow.
🤑 As for monetization…
The site started off ad free, but once traffic started picking up, Adsense was added. I’ve since migrated to a header bidding solution and try to recover adblocked traffic too as much as possible.
I love how this business started with Jason building a small tool for his own use.
Can you think of any issues you faced recently, even small ones? 🤔
Could you build a simple tool to solve that issue and put it online?

Hello, I’m a bit surprised of success of convertcase.net most of its functionalities can be found in Word
True, but many people don’t have Word or don’t know how to use it, or they don’t want to load up a big piece of software just to perform a simple function. Often quicker just to google a free tool that does the job and use that.
