Ask HN: Has anyone ever hired lots of developers and shipped faster as a result?

I've read plenty of horror stories about adding too many engineers too fast in high growth companies and the only real result being interview/onboarding chaos.

It feels like there's some complex function that describes optimal rate of hiring where you're optimizing for average speed of shipping...

Which tech companies have improved their engineering output successfully by hiring engineers fast? Why did it work for them?
