Marc Andreessen joins a16z's Head of Marketing Margit Wennmachers for the first episode of "4B with Margit" — a Clubhouse show  for raw and unfiltered advice from comms and marketing experts who have seen it all, as well as insider stories from the builders and pioneers who were in the trenches. Think “Scandal” meets “Halt and Catch Fire.” Catch it live Wednesdays 4-5 PST.  

In this episode: 

• What is a 4B? 
• What is the playbook for dealing with a crisis? And has it changed with the rise of social media and other direct channels?
• How does a company or startup build its media machine? And how should they think about different channels, especially new channels like Clubhouse?
• When do you add internal comms? And how do you (or even should you) set a policy for individual employees on social media?
