Thanks. We get that question a lot. I think currently it distinguishes;
- Shuttle allows you to make well designed sharing pages in your branding (wallpaper, logo). Looking to extend those customization features further. - Share pages can also be used to request files from others without them to require an account. - We allow you to connect your own storage account (Backblaze B2 or Amazon S3) turning it into a truly pay as you go storage - It's generally cheaper than Dropbox
Obviously Shuttle is just getting started and Dropbox is a big company that's been there for a long time. Instead of competing with Dropbox, we're currently looking into optimizing for niche like photography.
