The Magic Of Great Conversations

The Magic Of Great Conversations

Think back to the last time you had a really good conversation. How did that make you feel? People coming together to exchange thoughts, debate opinions, share advice – that's when the true magic happens ✨ And we are dedicated to bringing that enriching feeling of authentic human interaction to everyone, everywhere.

The idea for Angle audio was born when a physicist, an electrical engineer, and a designer walked into a bar – or a kitchen, in our case 😉 In early 2020, Matthias, Valerius, and Matthias K. reconnected over dinner, discussing ways to bring great conversations to people’s everyday lives. That first idea turned into a platform for audio group conversations, which catapulted us to the forefront of social audio.

👉 Throughout our journey, we discovered that special spark audio interactions add to customer engagement. We are now using our unique industry knowledge to enable organizations to add a social audio experience to their product that turns their audience into a community.
