tl;dr is that 1) It's a competitive domain, so we felt we needed to grow our team quickly to stay relevant 2) There's a lot of technical challenges with video editing in the browser + cloud, so we needed to be able to hire talented engineers to scale and 3) I believe there's a huge business in empowering creative teams, so we think we can get to venture scale and needed the capital to support that.
