About Zuma

Zuma makes an automated sales agent that converses with 100% of inbound leads, ultimately improving the way consumers interact with businesses and organizations. We’ve built this from the ground up using AI, ML, and human support which helps increase sales conversion and support capacity for businesses of all kinds. Zuma is one of the fastest-growing startups in Los Angeles, and is well-funded and backed by world-class investors such as Andreessen Horowitz (a16z), Y-Combinator, Joe Montana’s fund (Liquid 2 Ventures), Day One Ventures, Soma Capital, and other notable angel investors including Austen Allred (from Lambda School), YC’s former-COO Qasar Younis, among others.

Headquartered in Los Angeles, USA, we operate nationally and have plans to grow rapidly over the next few years. To do that, we need great people committed to our vision in a big way. We're looking to build a team of rockstars that are equally excited about the opportunity to leverage technology to improve the way customers interact with businesses!
