Uh, directors do not necessarily own a part of the company. Look up the companies celebrities have. It's easy to do on sites like this: https://www.zaubacorp.com/
Many celebs have companies that list their managers and other people. It does not mean those people own part of the company. They are just part of the administration or their names are used for tax purposes.
Unless you actually know about the internal finances, you cannot tell anything just based on who was on the board of directors.
