The Preview platform

There’s something magical about watching a developer in flow state, fingers flying as they type into Codex, Claude, or Cursor. A powerful creation interface unfolds in response to every keystroke, powering a workflow that would have been unrecognizable, even alien-like, to any professional software engineer just two years ago. The entire IDE has been torn down and rebuilt from scratch for the age of AI, and developers are flying as a result.

Video models have raced ahead over the same two years. Yet unlike coding, video creation remains stuck in the stone age, with its entire toolchain still built around capturing, uploading, storing, and editing enormous files.

Generative video is at a threshold moment: the models are now expressive enough to become the new camera. The bottleneck is no longer the technical art of animation or the $100M budgets for film crews and visual effects; it’s human creativity and token inference. But video creators are not yet flying.

Without a proper AI-native tool suite, or a “Cursor for video,” the people who make films, TV series, and commercials for a living remain stuck bolting model outputs onto legacy editing pipelines. Generation, review, and production tracking each live in a separate application; workflows buckle under the sheer volume of material; and a finished take often can’t be traced back to its source for legal clearance. It’s a gaping problem and is the biggest roadblock on the industry’s path to truly embracing AI.

Preview clears that block. An AI-native video creation and production platform built for professional creators, Preview combines a video timeline with an infinite canvas for ideation into one collaborative multiplayer workspace. Teams can generate with any model and track every character, location, and prop, with complete records of how every asset was made. It enables both halves of a hybrid production to work together seamlessly. There is simply nothing like it in the market.

Co-founders Stefan Fejes and Veljko Tornjanski have been best friends since high school in Serbia, and were seemingly born for this mission. They were founding team members at video creation pioneer Veed; later, at Vizcom, Veljko was the first hire and became Head of AI, while Stefan led Product. They understand well the tricky nuances of video, they have deep empathy for their customers, and they have delivered sophisticated, polished work on impressively short timelines.

More than 100 studios are already actively using Preview, from agencies making commercials for Fortune 500 brands to AI-native studios to Hollywood feature filmmakers. Simply put, they love it. Customers tell us it has become the most significant tool in their work, and the single source of truth from which all downstream inference flows.

We are at the precipice of a video token tsunami, and many billions of dollars of inference will run through this category, driving the next wave of iconic films and IP. Value will accrue to where the work actually happens—the platform a creative team opens in the morning and closes at night, where the decisions get made and the record gets kept. We believe Preview is that platform, and that this is the right team, the right product, and the right moment. We are thrilled to partner with Stefan and Veljko and to lead their seed round.
