YC S25 · Berlin · Founding Product Designer
AI motion design. Prompt-to-animation. On-canvas editing. The real stuff.
</aside>
You don't manage design. You make it.
We're building the AI motion designer — a tool where you describe what you want, get a professional animation instantly, then tweak it frame by frame on the canvas. Timelines. Keyframes. Easing curves. The controls that serious creators actually need.
We're 5–6 people. YC S25. 1,000+ active customers. Moving fast.
We need one more person to own the entire product experience from day one.
The role in one sentence

✏️
End-to-end product design for an AI-native creation interface — from the first sketch to the shipped pixel, with no PM layer between you and the founders.

Mission
Make the AI's output look so good that users get a wow moment every time they create a video.
Own two things:
- The motion design quality of what the AI produces
- The product experience of how people get there
Outcomes (12–18 months)
- Raise motion design output to a level that makes people want to share videos publicly. Define motion design rules, style parameters, and prompt templates that the agentic pipeline follows. Review output constantly, spot what feels off, and tighten rules and constraints until the default output is genuinely impressive.
- Design a creation flow that feels structured and intuitive. Define how users work step by step, from input to export.
