Ask HN: How to recruit a top notch CTO?

Hi HN,

This isn't intended to be a job advertisement, so I've omitted our company name.

We're a 2 year old company in the social gaming space with 7 figure annual revenue and profitable. Our products and company are growing and we have the opportunity to take it to the next level, but feel we need a stellar CTO/VP Engineering to lead the technology team. One of our technical co-founders fills this role now, but he's better utilized on the business side.

How have you recruited great CTOs for your companies? Have you used head hunters? Are there meet-ups that facilitate this type of high level recruiting?

Please share your thoughts. Cost isn't a factor because we're already profitable, we're really just searching for advice on finding top talent.
