AudioStack

AudioStack is a London-based AI startup founded in 2019 that provides an end-to-end platform to revolutionize large-scale audio production for enterprises. The company's technology suite enables scalable creation of studio-quality audio assets, including voiceovers, audio spots, dynamic creatives, custom brand voice synthesis (voice cloning), sound design, mastering, and delivery.

Through the use of AI, AudioStack empowers users to generate thousands of variations of audio assets at high speed, ensuring better quality based on voice, language, and call-to-action requirements. This significantly reduces turnaround time for audio production from several days to just a few hours or even minutes. The platform integrates cutting-edge technologies like text-to-speech, AI-based post-production, and audio versioning into a seamless workflow.

AudioStack's business model operates on a subscription basis, offering its services through flexible APIs and SDKs for Python and JavaScript integration. As of 2024, the company works with leading advertising agencies like Omnicom and Publicis, publishers such as Acast and iHeart, and global brands including McDonald's, Porsche, and Mountain Dew.

In February 2024, AudioStack raised a EUR 2.9 million pre-Series A funding round led by Quadri Ventures to support global expansion and enhance its AI-driven audio production capabilities. The company was previously acquired by Australian media company Unith in February 2021, raising GBP 1 million in seed funding to integrate AudioStack's technology into Unith's social commerce application.

Key customers and partnerships

In April 2024, AudioStack partnered with ElevenLabs to extend its synthetic voice offering, adding 66 new human-like multilingual voices to its platform. This collaboration aims to provide clients with a wider breadth of hyper-realistic AI voices, enabling endless creative possibilities through AudioStack's AI-powered audio technology.
