1) Building relationships across teams in a growing company is vital for success, as there are few formal processes and job roles are changing rapidly.
2) Knowing who to contact in other teams, especially in startups with high employee churn, is crucial. One should gather this information and share it, as it helps everyone navigate an uncharted organization.
3) Charting an organization by creating "Who to talk to" pages and seeding basic information, then asking others to update it, allows one to make valuable connections across the company as a remote employee.
