ElevenLabs is a voice artificial intelligence company founded in 2022 by two friends from Poland who were frustrated by how badly foreign films were dubbed into their own language. It builds speech synthesis, voice cloning, dubbing and conversational voice agents, and its models are widely regarded as the most natural sounding in the field, which has made it the default choice for audiobooks, video localisation and voice interfaces. Headquartered between London and New York and valued in the billions, it has also had to build unusually strict consent and detection controls because voice cloning is so easily abused.

Skild AI is building a general purpose robot brain that transfers across different machines and tasks rather than being trained for one robot at a time. Its models learn from a very large and diverse dataset of robot and human interaction, and the company has demonstrated locomotion, manipulation and inspection behaviours on multiple hardware platforms. The laboratory was founded by robotics faculty from Carnegie Mellon University and raised one of the largest rounds in embodied artificial intelligence.
