We help you tell your stories, on your terms
We believe how you tell a story is just as important as the story itself, so we are giving creators around the world—from first-time podcasters to pros—the ability to take control of their voices.
Be in the moment
Don't spend your time worrying about too many uhs, umms, or pauses. We'll handle all aspects of editing so you and your guests can focus on sharing your voices.
Reach a bigger audience
A lot of Podcasts don't publish videos because of the nuances associated with video editing. With us by your side, you can publish to both mediums.
Attract more advertisers
Advertisers (especially the big ones) are looking for Podcasts that can deliver their message loud and clear. Professional editing helps you achieve that.
Save some money
When you work with Castup, you don't have to spend your money on other editing, storage, media, or other software subscriptions, which means savings for you.
Faster than any text-based audio editor because our team of editors takes care of fine-tuning every cut, adding music, and sound effects for you.
