About Playback

Playback is pioneering the future of watching sports. We believe sports are at their best when enjoyed together — with your friends, at a bar, or in the stadium — but online streaming remains a frustratingly solitary experience. Playback is rethinking sports streaming as a community-first activity, building a home for sports creators (think podcasters) and their communities to watch live games together, all in perfect sync. Check out our demo video for more detail.

We’ve raised over $6M from Khosla Ventures and other top tier investors - come help us build the future of watching sports!

Why work at Playback?

At Playback, you’ll have the opportunity to build a potentially category-defining product in a massive market. As an early hire, your contributions will have a tangible impact on the future of our product, and you’ll have the opportunity to define your own role as we grow.

We’re well-funded, have product market fit, and our user base is highly engaged and growing quickly — our average user spends over 2 hours and 15 minutes in a Playback room every week! And in a world of buzzwords and cliches, we genuinely believe that our product enriches our users’ lives by providing meaningful social experiences. As one of our users described it, “I love this - normally I am yelling at the TV by myself, now I get to yell with everyone else!”
