Lemon Slice just raised $10.5M seed from Matrix Partners, YC, and The Chainsmokers for AI avatars that actually work. What it is: Real-time interactive video avatars from a single photo. 20B-parameter model running 20fps on single GPU. • Founded 2024 by 3 PhDs (Lina Colucci, Sidney Primas, Andrew Weitz) • Built proprietary video diffusion transformer (not just face-swapping) • API + embeddable widget (1 line of code integration) • Works for human + non-human characters • 8-person team, targeting education/e-commerce/training How it happened: • Started in YC experimenting with video models • Realized interactive video was the missing layer for AI agents • Built end-to-end diffusion model vs. piecemeal solutions • Focused on solving "uncanny valley" problem competitors ignore • Launched with both API and no-code widget for fast adoption • Secured high-profile angels (Dropbox CTO, Twitch CEO) Link: https://www.finsmes.com/2026/01/lemon-slice-raises-10-5m-in-seed-funding.html Takeaway: Video avatars failed before because they were creepy. Build the foundational tech right, and distribution follows. Source: FinSMEs Brewed by Startup Beaker.
