I'd be curious to read some coverage of what some of these companies achieved during yc. What they had coming in, what did they work on, manage get done, etc... Writing software, getting customers.. For example: "Withfriends: Membership programs for small businesses like bars, theaters, and barbershops. So far they have 80 small businesses on the platform, with over 5000 members* How much of this was achieved during YC. Were they writing code in a flat? Selling businesses door-2-door? Did they have product and get the customers? Both? Neither?
