Hera

Hera is an AI motion designer built for video professionals and content creators who need studio-quality animations without the manual effort. Founded in 2025 by Peter Tribelhorn and Chia-Lun Wu and backed by Y Combinator (S25), Hera generates code-based animations from text prompts in seconds — covering product launch videos, animated infographics, social media overlays, and explainer content. Unlike traditional video-generation tools, every parameter in Hera's output is fine-tunable after generation, giving creators precise control over the final result. Since launching, Hera users have created over 200,000 animations and the platform draws approximately 200,000 monthly visitors, making it one of the most-trafficked startups in its YC cohort.
