How do I prepare for a family office meeting?

Family Offices typically require a substantial diligence process. They want to ensure that your firm will be in business for a long time and has a major edge over the 100s of mangers they diligence every year. In general, Family Offices like to invest in VC funds for direct follow on and co-investment opportunities. Be prepared to answer a litany of sourcing related questions such as:

What channels do you use to source besides traditional accelerator demo days?
How do you win competitive deals?
What is your process for narrowing opportunities? Note: they are trying to identify that you have logical approach that you can scale. 
What signal do you communicate to the market after you invest in a company?
What is your co-investment strategy/policy? 

Then, be prepared to share a robust data room that includes the following: Presentation, Deal Memos, References, Research, Models, Bios and Legal Agreements.
