This document discusses when and how to use Drupal for a startup business. It recommends using Drupal early in the development process to commit code often. Drupal is best for startups that need to build a community of paying and nonpaying users and need to track key metrics like issues solved and site speed. Outsourcing development or using coworking spaces can help get past the learning curve. Costs may range from $5,000 per month for development to $70,000 for a full project. Drupal is suitable when the focus is on building a platform beyond initial development.
