About Us
We're redefining entertainment with AI. We're one of the fastest-growing startups globally, serving 20 million users in our first year — and we're just getting started.
We're an in-person company based in Sydney, Australia, guided by a set of principles that are foundational to everything we build:
- User-first — We build things that people want. We invest time to understand our users and focus on adding value instead of extracting value.
- High agency, high ownership — We're responsible for the pieces we own, end-to-end. We own every mistake, figure out what went wrong, and fix it. We don't blame anyone or anything else.
- Urgency — This is a once-in-a-lifetime opportunity. We prioritize well, find ways to increase leverage, and move at an inspirational pace.
