Perfect subtitles, faster: the beginning

What began as a client need became a platform used by the world’s biggest brands. CaptionHub was built to make high-quality media localisation fast, scalable, and effortless.

Trusted by the biggest brands

CaptionHub is the single source of truth for video and audio translation at the world’s largest companies — across recorded and real-time content.

Global scale, local impact

Headquartered in the UK and fully remote, our team and partner network spans the globe, delivering in over 400 languages at scale.

2015: The challenge

It all started with a global retailer who needed launch videos subtitled overnight. CaptionHub was born out of solving that problem.

Scaling with demand

By 2017, CaptionHub had become the localisation partner of choice for broadcasters, streamers, and Fortune 500s around the world.
