You are joking? You really think a book will get filled by using onmarket platforms, friends and family? What incentive is there for people to hold?
When you use a single "quality" broker, they will generally have good relationships and an existing client base of loyal sophisticated investors with deep enough pockets.
A quality broker will then ensure that the deal is corner stoned by large investors that they trust to be in teh stock ling term and then supplement this with other loyal investors. If need be they may use an alternate broker or an alternative online platform to get basic spread. This ensure there is liquidity moving forward (as many will flip) and that they get the minimum shareholder numbers.
