AI character video platform - Character-3 model generates lip-synced talking portraits with facial micro-expressions; 3M+ users, $42M raised from a16z.

Hedra is an AI character video generation platform built on its proprietary Character-3 model - described as the first omnimodal foundation model for digital characters that simultaneously processes image, audio, and text to produce phoneme-accurate lip-sync, natural micro-expressions, and eye movement from a single static image. Founded in 2023, Hedra launched publicly in June 2024, reached nearly 3M users who created 10M+ videos, and raised a $32M Series A led by a16z Infrastructure in May 2025 at approximately $200M valuation. The Infinite Canvas video editor allows composing and chaining character video clips in a full non-linear workflow. Live Avatars extends Character-3 to real-time streaming at $0.05/minute for interactive applications. A free tier provides 300 credits/month (watermarked output) with no credit card required.

Cons

Free plan watermarks all output and restricts commercial use - any professional content requires at least the $15/month Basic plan immediately
Clip length and resolution limits per generation restrict use in professional broadcast or feature-length production contexts
Platform is still maturing - multi-character scenes and complex scene composition require manual workarounds in the Infinite Canvas editor
