You can always have a choice to start small business first using your own money/ family money with 100% shares ownership, then, you grow big soon and later or getting a huge investment fund to lose money for the first few years with only slightly more than 1% of shares of the total shares you have in your business

Of course, there are exceptions.

Let's explore the total wealth which Grab CEO and Founder has in GRAB taxi, i.e. 2.2% shares.  He is definitely not the decision-maker because his percentage of shares is not the largest portion among the group.  With 2.2%, his net worth is USD 829 million.  My startup, www.SoLemMi.com  is going after GRAB's investment model, i.e. lose money for a few years first and earn it very soon.
