This document introduces the GM Suite, which provides a set of best practices for startups to manage communities using existing online tools. It aims to help startups overcome common problems like poor testing of hypotheses, lack of transparency, excessive spending, and co-founder issues. The GM Suite recommends tools for tasks like marketing, discussions, sharing information, and project updates. It also suggests using tokens to motivate community contributors who help with pivots to become shareholders. While public communities can help testing, unstructured management may distract founders. The GM Suite provides a structured approach using tools like Twitter, LinkedIn, Notion, and token-based systems.
