Papercup has secured £16.2m in a Series A funding round led by Octopus Ventures to support its machine learning research and language expansion. The London-based AI start-up attracted participation from a broad syndicate including LocalGlobe, Sands Capital, Sky, and Guardian Media Ventures. The capital will be deployed to scale its synthetic voice technology and drive further commercialisation across global markets.
From the founder
"People retain up to 70% more information when watching videos dubbed in their native language. With truly emotive cross-lingual AI dubbing, we can tackle all forms of content, making video and audio more accessible and enjoyable for everyone. This funding will allow us to double down on our promising research and break into new content categories."

Jesse Shemen
CEO at Papercup
Investor perspective
"Spotify has 3.2 million podcasts. Youtube 500 hours of video uploaded every minute. Discovery, 100,000 hours of documentaries. CNN 4 million video assets. The volume of video and audio produced for consumption is rising exponentially, yet, only 1% is currently dubbed into multiple languages. Papercup’s use of AI to provide affordable, high quality dubbing can unlock that content for audiences around the world and in, doing so, drive a 100 fold expansion in the video and audio translation market with Papercup at the forefront."
