I've been editing videos since I was a kid. At 16, I started making YouTube thumbnails in 3D and giving them away for free to small creators. Their videos started getting more views, and that's when creators started paying me.

I did every part myself, from coming up with the idea to the final image. Over time I started writing scripts too, for long videos and short ones. And I kept asking myself why some videos get clicked and others don't.

Then I found people online building real businesses from nothing, and I became obsessed. I started teaching myself how businesses actually work in my spare time. That's what led me to start Adgenic, where I use everything I've learned to help businesses sell more and stand out.
