🚀 Whatnot

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!

Partner closely across the machine learning, platform, and product engineering teams to train models to solve product problems and productionize data science and machine learning artifacts.
Contribute scalable solutions across various serving stacks at the machine learning service and application layers.

Develop high quality communication devices such as dashboards, notebooks, documents, and presentations to convey insights across a broad audience.
Define and advance our technical approach to scalable machine learning.
