Founding Product Designer at Hera (YC S25)
We're building the world's first AI motion designer that creates professional animations in seconds.
About Hera
Video is the most effective medium, but video creators waste countless hours animating seconds of content. Motion design tools like After Effects require mastering complex user interfaces, turning creative work into button-clicking hell. We're starting with motion design because it's the most painful and expensive part of video creation.
Hera is the first AI motion designer that creates professional animations through conversation. Unlike video-gen tools, Hera generates code-based animations where every parameter can be fine-tuned through prompts or on-canvas editing, giving users the control of After Effects with the simplicity of Lovable.
In our first two weeks after launch, users created over 200,000 animations.
Our founders:
Peter Tribelhorn (CEO) built YouTube channels with 50B+ views. Chia-Lun Wu (CTO) was one of the first developers at Vyond, where he built their video editor used by 20,000 businesses today.
