Having worked at a company that went from < $50 million to > $1 billion in less than 10 years I think the biggest dark side is when it's all over. Either the company will get bought, leadership will leave and company priorities will change -- or you'll just end up leaving. When you decide to move on, you'll notice that all other companies seem less smart and a LOT less intense. You might find yourself attempting to unsuccessfully chase that high that you had before when working for a successful startup or attempting to 'go back to the way it was' ... but the odds are stacked against you. There's no going back. And there's no recreating what you had. Just treasure it. Very few devs get the opportunity to work for a startup. Even fewer get the opportunity to work for a successful startup.
