Whatnot (YC W20) is a livestream shopping platform and marketplace backed by Andreessen Horowitz, Y Combinator, and CapitalG. We’re one of YC’s top companies and one of the fastest growing marketplaces ever. We’re laser focused on creating an exceptional software company, team, and place to work. You can read our principles here.

Our mission: enable anyone to turn their passion into a business and bring people together through commerce. We’re building the future of ecommerce; an interactive community where creators can make a living off their passion.

Did we mention we’re growing? In January 2021, Whatnot had 10 ambitious employees. We started 2023 with 350+ employees and are continuing to grow. We’re hiring forward thinking problem solvers across all functional areas. We recruit thoughtfully, can adapt quickly, and are scaling fully remotely.

Opportunity Size

The e-commerce experience has been static for 20+ years and is one of the largest opportunities for disruption in the startup space today. Livestream shopping is a $300B GMV market in China and has grown 100% YoY. Retail is a $5T market opportunity!


  • Help us launch a world-class live shopping platform into new categories, such as clothing, luxury, and sneakers, by contributing to the development of both category-specific and platform-wide features and infrastructure.
  • Deliver useful, fun, trusted, and seamless user experiences to help people find what they’re looking for, enjoy their time on Whatnot, and share with their friends.
  • Help recruit and grow successful sellers to Whatnot, by working closely with our marketing & operations teams to identify seller needs, pain points, and opportunities, and designing and implementing effective solutions.


Curious about who thrives at Whatnot? We’ve found that low ego, a growth mindset, and leaning into action and high impact goes a long way here.
