About ai|coustics
At ai|coustics, we’re building the quality layer for Voice AI. Our AI-powered speech technology turns any audio - live or recorded - into studio-quality output in real time. Since our launch, we’ve built a community of over 500,000 users, have processed more than 2 million audio files and signed contracts with leading audio brands like Elgato, Radio France International or Deutsche Welle.
We recently closed our 5M Seed round with leading investors like Partech and Connect Ventures alongside Inovia Capital, FOV Ventures, Intuition and Arc Investors. We’re at a pivotal moment of growth and product innovation - and we’re looking for ambitious builders to join us on this journey. If you’re excited about defining a new category in Voice AI and shaping the future of audio, we’d love to meet you.
