Why would you be worried that your employees will leave after you've helped them grow and develop? If you're hiring employees for potential and fit rather than just going after people with big names on the resume (Stanford, Google, Apple, etc) you're not going to have to pay exorbitantly to get them in the first place. Or at the very least, you'll be able to hire faster and spend less money chasing a very small group of devs.

Put another way, you'll spend less money overall if you can identify, hire, and retain undervalued talent. If you build an exceptional workplace (and pay well) most will want to stay. And if you've done that, it'll be far easier to attract talent in the future.
