As a sole-owner and President of a boutique real estate company I have what I call my own, private advisory board of amazing experts at the top of their game in all aspects from finance to HR but one-on-one. They are all so busy that it would be impossible to meet all together with me at the same time four times a year; impossible for them and for me to plan! So I just pay them for them time and meet with them either regularly or on an as-needed basis. And it works amazingly well for me. I don't know what I would do without the 5-6 of my functional experts and friends. My start-up went from 0-$91M in sales in 6 years, creating the number 1 ranked agent team in our MLS system too 4 years in a row. Just met with one last night over a huge hiring need I have now. Great article.  So true. I know where my expertise lies and where it doesn't! So I go to the pros who tell me what I should consider.
