Lina Colucci is co-founder and CEO of Lemon Slice, a frontier AI lab building interactive video. She shipped Lemon Slice-2, a 20B-parameter real-time diffusion model that renders an animated avatar at 20fps from a single photo on a single GPU. A second-time technical founder (previously Infinity AI, a synthetic-data company; both ventures went through Y Combinator), she is actively defining the interactive-video layer of the agent economy — making her session valuable for anyone working on real-time avatars or agent UX.
