Of Family Offices (private family funds) US under $500mm.

Given the vague nature of the term 'Family Office', coming up with an exact count is more difficult. According to the Wall Street Journal, the threshold for single family offices is generally considered to be $100 million due to the costs and challenges of running such an entity. In the United States alone, there are approximately 20,407 individuals with more than $100 million in assets, as reported in the Credit Suisse 2018 Global Wealth Report. Of these individuals, 1,144 have over $500 million in assets. According to Family Office Exchange, a network of family offices and their managers, roughly 50% of high net worth individuals with assets between $100 and $500 million have a family office, resulting in 9,631 private family funds with assets under $500 million.

Keep in mind that this is an estimate and other sources disagree with this number. Family Wealth Report estimated that there were about 6,000 family offices total while Campden Wealth puts the figure at 7,300. That said, Family Office Exchange holds a bienniel survey of family offices and boasts that they are the "The world’s largest peer-to-peer network for ultra-wealthy families and their family offices and the leading authority on matters related to legacy wealth management."

Of venture capital funds in the US under $500mm:
  • Is this asking the number of VC firms with AUM under $500mm or the number of current funds in the US that are less than $500mm. So for instance, if a VC firm is on fund VII, and has 7 funds of $100 million (i.e. $700mm AUM) do you want that to be counted as 7 funds or does this firm not count because it has over $500mm in AUM. Either way, both are murky. If it's the former, it's hard to determine when a fund is 'closed' i.e. is no longer listed. If you want firms with AUM less than $500mm, knowing AUM would require access to a VC firm's internal valuation marks for all of its portfolio companies plus its remaining dry powder from previously raised fund(s).
