How Work Affects My Life:

Our Vision

Calling a business shouldn’t feel like a robot-hostage situation, where you’re forced to listen to horrible music and can't reach a human, while enduring a soulless voice uttering "I'm sorry I didn't quite get that" on repeat for eternity. (shudder) That’s why we started Slang.ai*.*We use the latest AI and audio wizardry to make transacting via voice so enjoyable it’s more human than human. By 2030, we will save businesses and consumers 1 billion minutes of precious time while transforming voice channels into the preferred mode of communication (it's faster and easier than text).

We have backgrounds building product at companies like Spotify, Buzzfeed, the New York Times, and OpenTable —shipping experiences that have reached hundreds of millions of users. Now, we’re using our backgrounds to start a new culture, one that puts product and human-centered design above all else while fostering constant learning and growth. Sound like something you’d like to be part of? Get on board.
