Brian Rothenberg - Building market places from zero to billions

Key points for building market places

- The only thing that matters: Build liquidity - the first one there wins

sellers can expect their items will sell
- buyers can expect to buy items at price they can accept
- cross side network effects - one side drives the other side

- Always start with building building Supply first

seek out inefficient, fragmented markets that you can roll up
- look for fragmented + high friction for supply sign up
- pick method that works for your target market
- Methods

trojan horse strategy - provide immediate value through the offer of the use of a tool - SAAS model

- Challenges

In the short run supply is always the challenge
- In the long run demand is the bottleneck

- Network effects create virtually impenetrable barriers to entry

retention grows
- increasingly attractive economics
- reaching scale as fast as possible matters

- Competition

horizontals are going vertical
- horizontals that fail to go vertical lose market shares - craiglists
- moving forward focus on building niche networks
- technology shifts sometimes open new windows to attach horizontal market positions
- Winner either take most or takes all

- Operations

track satisfaction / separate NPS for both supply and demand side
- more satisfied demand side drives growth
- very powerful dynamic:

look for overlap between buyers and sellers
