About Preview

Preview.io operates as an AI-native video creation and production platform designed for professional creators, studios, and filmmakers. The company was co-founded by Stefan Fejes and Veljko Tornjanski, who have been friends since high school in Serbia. In August 2026, it was announced that Sequoia Capital led the company's seed funding round. The founders possess significant experience in the video and AI sectors. They were part of the founding team at the video creation company Veed.io and later held key positions at Vizcom, where Veljko was the Head of AI and Stefan led Product. This background provided them with insights into the nuances of video technology and customer needs, leading them to conduct over 100 interviews to refine Preview's product direction. The platform addresses inefficiencies in the AI filmmaking pipeline by providing a unified, collaborative workspace. It integrates an infinite canvas for creative ideation with structured production tools like a video timeline, storyboards, and shot lists that can be generated from a script. This allows creative teams to move from initial concept to final cut within a single environment. The system is model-agnostic, enabling users to generate video and images using various frontier AI models side-by-side. Key features include tools for maintaining consistency across projects, such as a 'Camera Bag' for defining a unique visual style and the ability to save and reuse characters, locations, and props. A core component is its ability to provide complete provenance for every generated asset, creating a verifiable record of who created it, with which model, and at what settings, which is crucial for compliance and client reviews. The platform also includes a 'Preview Agent,' an AI assistant that helps with tasks like script breakdowns and exploring creative directions. The business model is credit-based, where users pay for usage without a recurring subscription. Preview targets a professional clientele, with over 100 studios, including agencies creating commercials for Fortune 500 brands and Hollywood filmmakers, actively using the platform.
