Video editing is the final frontier of software tools moving to the cloud. We're making the next generation of modern creators tools to enable everyone to share their story online. Join us at Kapwing on our mission to make content creation fast, accessible, and collaborative.


Everyone is a creator. The problem, however, is that today's tools get in the way of expressing our creativity fully. Especially when it comes to video, the gap between an idea and a video is wide enough that it's hard to even start.


Our mission at Kapwing is to make content creation easier and more accessible. Our main product, Kapwing Studio, is an online video editor that is both powerful and easy to use. Millions of creators every month choose Kapwing to tell their story and bring their ideas to life.


Our vision is to build a modern video editing platform that serves as the go-to tool for anyone creating video for Youtube, social media, or work. Kapwing turns video editing, traditionally a heavyweight, time consuming workflow, into a joyful, collaborative experience. We believe that we can use technology to augment the video editing and content creation experience, and we've already started on this path with a wide array of templates, applications of artificial intelligence, and new pipelines for exporting and video processing.


Join us on our journey to democratize creative tools and invent the future stack of video creation.
