When a startup grows beyond its initial small team, internal communication becomes increasingly challenging. To overcome this, companies like Intercom have implemented various mechanisms to ensure information flows clearly and smoothly across teams. These include bi-weekly "All Hands" meetings where the CEO answers questions and shares updates on company goals, strategic projects, and business performance; weekly "Show and Tell" sessions where employees share their work with the whole company; and a weekly newsletter that informs and reminds employees of important dates, product releases, or media coverage. To make internal communications effective, it's essential to be inclusive, practice patience and persistence, lean on subject-matter experts, be organized but flexible, find a tone of voice, value transparency, schedule for everyone, and continue adapting as the organization grows. By implementing these techniques, companies can maintain alignment, build camaraderie, and stay connected as they scale.
