If you're a founder of a venture backed company, one of your main jobs is to build a pipeline of investors and constantly be planning for the next round of funding (that takes a significant amount of energy away from building the company).
With this strategy, you raise one round, then you go back to being similar to a bootstrapped founder where your only focus is to make the business sustainable and you're not spending mind-share trying to raise more money.
So it is a different way of building.
do you have some statistics to that? i'd expect that most startups that raise only once do so because they failed before they could raise again.
how many startups raise once and then become a successful profitable business without ever raising again? that's what "this third" way is about.
This is qualitatively different from the founders collectively having a majority of the shares (even factoring in granting tons of equity to thousands of employees), or, if not, they at least control a majority of the board seats for a long time, if not forever.
Honestly, implementing a 10M share one class common company just to make a VC happy sends horrible signals for negotiating with investors. It shows that you are happy to pre-negotiate against yourself from the get go just to look VC friendly. If you cared about retaining control, why would you do that?
