Role overview
Known is a matchmaker that talks to users and supports them like a friend. Our mission is to empower humanity by applying general intelligence to human connection.
Users join Known by telling us their life story. On average, our new users talk to our AI voice agent for 27 minutes, giving us a uniquely intimate multi-modal data set.
We are a team of engineers who’ve created some of the most widely used AI-driven consumer products including Uber Eats, Uber, Faire and Afterpay.
We love to work hard, with a high degree of autonomy and ownership. We work together in Cow Hollow, San Francisco.
How It Works: On Known, who you see is intentional by design.
There's no feed to scroll. No feeling that someone better is one profile away. It starts with a conversation with Known. Understanding who you are, how you live, and what you're actually looking for. You're introduced to one person at a time, guided by what Known learns about you. Your profile is created for you, dynamically. It evolves as Known gets to know you better. When you're curious about someone, you can ask Known questions. The things you'd normally wonder but never quite know. When interest is mutual, Known takes care of what's next. Schedules are coordinated. The venue is chosen. And the date is set. Less scrolling. More
