In its early days, Facebook couldn’t grow as quickly as it would be able to had to launched yesterday. And that, Dustin Moskovitz told the crowd at PandoMonthly, contributed to the site’s success.

Had AWS, Amazon’s cloud services business, existed today, Facebook probably would have scaled out way faster than it did, he said. Back in 2004, the company had to wait three months for it’s server orders to come in before it could roll out to new colleges.

If Facebook had grown as quickly as it wanted, the competitors may have caught on faster and sprung up to imitate the small company, he said.

Facebook took the same approach on hiring. At the advice of Peter Thiel, the company didn’t hire as fast as it wanted to, which was, in retrospect, Moskovitz said, a good thing.

“Peter thought headcount was growing too quickly,” he said. “It was easy to get caught up in fast user growth and hire as quickly as possible. But it ends up lowering your quality bar, and there’s culture dilution and mission dilution and a bunch of people that don’t necessarily think about the company the same way the earlier people to join the company do.”

Moskovitz and crew hired at Facebook faster than Peter wanted them to, but were it not for him, they wouldn’t have held back at all, and that slowness was key to keeping Facebook’s culture intact.
