Product Context (5 minutes)

Facebook Marketplace is a platform within the Facebook ecosystem that enables users to buy and sell items locally. It leverages Facebook's vast user base and social graph to create a peer-to-peer marketplace experience.

Key stakeholders include:

1. Buyers: Seeking good deals on local items
2. Sellers: Looking to monetize unused items or run small businesses
3. Facebook: Aiming to increase user engagement and monetization
4. Advertisers: Interested in reaching users with high purchase intent

User flow:

1. Discovery: Users browse listings or search for specific items
2. Interaction: Interested buyers message sellers for more information
3. Transaction: Buyers and sellers agree on terms and complete the sale offline

Marketplace fits into Facebook's broader strategy of increasing user engagement and time spent on the platform. It also aligns with their goal of connecting people and fostering local communities.

Competitors include platforms like Craigslist, eBay, and local buy/sell groups. Marketplace differentiates itself through its integration with Facebook's social network and user profiles.

Product Lifecycle Stage: Marketplace is in the growth stage, continuously expanding its user base and features while still having room for significant improvements and market penetration.
