Companies have been operating remotely and/or distributed for much longer than 2 years. Pretty much every company I worked for from 2010 onwards had at least half the team separate from the "sales office" that owned the relationship. Most often this was having dev teams in South America or Eastern Europe, but pretty frequently we just had multiple offices in the US working together. And frequently with clients that were in a third location. Slack, Zoom, JIRA. That's all you need.
