Bug Crowd proved its two-sided marketplace viability without writing code. They used social media to attract 5,000 hackers and managed them via MailChimp. They used Wufoo forms for vulnerability submissions. The first code was only written on a plane to San Francisco for their seed round, after validating the core model.
