Timing really matters here.
In most well-run SaaS organizations, the VP of Sales is constantly using the SDRs as a farm team for AEs. In part to groom great AEs, but also maybe even more so, to provide SDRs a career path. The reality is in a perfect world, your best SDR would always stay an SDR. But the best ones often want to get “promoted” to AE (or group manager of SDRs). By providing a career path, good VPs can recruit more SDRs.
The problem is time, and timing. They are only so many you can promote. And you also need to bring in outsiders too.
So typically what happens is at first, there’s no room to promote, because you are just building an SDR team. Then you start to grow quickly. And there’s room to promote 1–2. And then. You hit a few speed bumps. And that promotion path gets all shut down.
